SETI forsker Seth Shostak vædder med at vi vil finde udenjordisk liv i løbet af de næste 24 år, eller han giver han en kop kaffe. Ved TEDxSanJoseCA forklarer han hvorfor nye teknologier og loven om sandsynlighed gør gennembruddet så forventeligt -- og forudsiger hvordan opdagelsen af civilisationer der er langt mere avanceret end os vil påvirke os her på jorden. (Filmet ved TEDcSanJoseCA.)

Is E.T. out there?

Er E.T. derude?
00:13
Well, I work at the SETI Institute.
1
1037
2979
Jeg arbejder ved SETI instituttet.
00:16
That's almost my name. SETI:
2
4016
1235
Jeg hedder næsten SETI:
00:17
Search for Extraterrestrial Intelligence.
3
5251
2407
Search for Extraterrestrial Intelligence.
00:19
In other words, I look for aliens,
4
7658
1619
Jeg søger altså efter rumvæsener,
00:21
and when I tell people that at a cocktail party, they usually
5
9277
3668
og når jeg siger det til fester,
kigger folk som regel
kigger folk som regel
00:24
look at me with a mildly incredulous look on their face.
6
12945
2761
på mig med et skeptisk blik.
00:27
I try to keep my own face somewhat dispassionate.
7
15706
2333
Jeg prøver at holde et neutralt udtryk
00:30
Now, a lot of people think that this is kind of idealistic,
8
18039
2760
Mange mener, dette er lidt idealistisk,
00:32
ridiculous, maybe even hopeless,
9
20799
2250
latterlig, måske endda håbløst,
00:35
but I just want to talk to you a little bit about why I think
10
23049
3705
men jeg vil bare tale lidt om,
hvorfor jeg mener
hvorfor jeg mener
00:38
that the job I have is actually a privilege, okay,
11
26754
3814
at det job jeg har
faktisk er et privilegium, okay,
faktisk er et privilegium, okay,
00:42
and give you a little bit of the motivation for my getting into
12
30568
2098
og fortælle jer om motivationen
for at starte
for at starte
00:44
this line of work, if that's what you call it.
13
32666
2355
denne karriere,
hvis man kan kalde det sådan.
hvis man kan kalde det sådan.
00:47
This thing — whoops, can we go back?
14
35021
3008
Denne ting -- oops, kan vi gå tilbage?
00:50
Hello, come in, Earth.
15
38029
2699
Hallo Jord, kom ind.
00:52
There we go. All right.
16
40728
1351
Sådan. Okay.
00:54
This is the Owens Valley Radio Observatory
17
42079
1993
Dette er Owens Valley Radio Observatory
00:56
behind the Sierra Nevadas, and in 1968,
18
44072
3436
bag Sierra Nevadaerne, og i 1968,
00:59
I was working there collecting data for my thesis.
19
47508
2909
arbejdede jeg der
og indsamlede data til mit speciale.
og indsamlede data til mit speciale.
01:02
Now, it's kinda lonely, it's kinda tedious, just collecting data,
20
50417
3341
Det er temmelig ensomt arbejde,
temmelig ensformigt at indsamle data,
temmelig ensformigt at indsamle data,
01:05
so I would amuse myself by taking photos at night
21
53758
2533
så jeg underholdte mig selv
med natlig fotografering
med natlig fotografering
01:08
of the telescopes or even of myself,
22
56291
2761
af teleskoper eller af mig selv endda,
01:11
because, you know, at night, I would be the only hominid
23
59052
5234
fordi jeg om natten,
var jeg den eneste hominide
var jeg den eneste hominide
01:16
within about 30 miles.
24
64286
1748
i cirka 50 kilometers omkreds.
01:18
So here are pictures of myself.
25
66034
2009
Her er billeder af mig selv.
01:20
The observatory had just acquired a new book,
26
68043
3588
Observatoriet havde lige fået en ny bog,
01:23
written by a Russian cosmologist
27
71631
1750
skrevet af en russisk kosmolog
01:25
by the name of Joseph Shklovsky, and then expanded
28
73381
3618
der hed Joseph Shklovsky,
og derefter udvidet
og derefter udvidet
01:28
and translated and edited by a little-known
29
76999
2453
og oversat og redigeret af en ukendt
01:31
Cornell astronomer by the name of Carl Sagan.
30
79452
2609
astronom fra Cornell, der hed Carl Sagan.
01:34
And I remember reading that book,
31
82061
1997
Og jeg kan huske at have læst den.
01:36
and at 3 in the morning I was reading this book
32
84058
2008
Jeg læste den klokken 3 om morgenen
01:38
and it was explaining how the antennas I was using
33
86066
2693
og den forklarede,
hvordan de antenner, jeg brugte
hvordan de antenner, jeg brugte
01:40
to measure the spins of galaxies could also be used
34
88759
4947
til at måle galaksers rotation,
også kunne bruges
også kunne bruges
01:45
to communicate, to send bits of information
35
93706
2312
til at kommunikere,
og sende information
og sende information
01:48
from one star system to another.
36
96018
2592
fra et stjernesystem til et andet.
01:50
Now, at 3 o'clock in the morning when you're all alone,
37
98610
1468
Klokken 3, når man er alene,
01:52
haven't had much sleep, that was a very romantic idea,
38
100078
2931
og ikke har fået meget søvn,
var det en meget romantisk ide,
var det en meget romantisk ide,
01:55
but it was that idea -- the fact that you could in fact
39
103009
3889
men det var den ide,
det faktum at man faktisk kunne
det faktum at man faktisk kunne
01:58
prove that there's somebody out there
40
106898
1484
bevise at der er nogen derude
02:00
just using this same technology --
41
108382
2716
ved hjælp af den samme teknologi --
02:03
that appealed to me so much that 20 years later I took a job
42
111098
2230
der 20 år senere fik mig ind i jobbet
02:05
at the SETI Institute. Now, I have to say
43
113328
1973
ved SETI Institut. Nu må jeg så sige
02:07
that my memory is notoriously porous, and I've often
44
115301
4450
at min hukommelse er notorisk porøs,
og jeg har tit
og jeg har tit
02:11
wondered whether there was any truth in this story,
45
119751
1833
tænkt på, om historien er sand
02:13
or I was just, you know, misremembering something,
46
121584
1504
eller om jeg husker forkert,
02:15
but I recently just blew up this old negative of mine,
47
123088
2748
men for nyligt forstørrede jeg
dette gamle negativ,
dette gamle negativ,
02:17
and sure enough, there you can see
48
125836
1599
og søreme så, der kan man se
02:19
the Shklovsky and Sagan book underneath that
49
127435
2111
Shklovsky og Sagan bogen der ligger under
02:21
analog calculating device.
50
129546
2477
analog regnemaskinen.
02:24
So it was true.
51
132023
903
Det var sandt!
02:24
All right. Now, the idea for doing this, it wasn't very old
52
132926
2441
Idéen bag var ikke særlig gammel,
02:27
at the time that I made that photo.
53
135367
1664
da jeg tog billedet.
02:29
The idea dates from 1960, when a young astronomer
54
137031
3478
Ideen stammer fra 1960, da en ung astronom,
02:32
by the name of Frank Drake used this antenna
55
140509
2496
der hed Frank Drake brugte sin antenne
02:35
in West Virginia, pointed it at a couple of nearby stars
56
143005
3610
og stillede den ind
på et par nærliggende stjerner
på et par nærliggende stjerner
02:38
in the hopes of eavesdropping on E.T.
57
146615
3389
i håbet om at smuglytte på E.T.
02:42
Now, Frank didn't hear anything.
58
150004
1596
Nu hørte Frank ikke noget.
02:43
Actually he did, but it turned out to be the U.S. Air Force,
59
151600
2409
Eller jo, men det viste sig
at være U.S. Air Force,
at være U.S. Air Force,
02:46
which doesn't count as extraterrestrial intelligence.
60
154009
2965
altså ikke udenjordisk intelligens.
02:48
But Drake's idea here became very popular
61
156974
2766
Men Drakes ide blev meget populær,
02:51
because it was very appealing — and I'll get back to that —
62
159740
2457
fordi den var meget tiltalende,
02:54
and on the basis of this experiment, which didn't succeed,
63
162197
3416
og på baggrund af det eksperiment,
som ikke lykkedes,
som ikke lykkedes,
02:57
we have been doing SETI ever since,
64
165613
1855
har vi udført SETI lige siden,
02:59
not continuously, but ever since.
65
167468
2034
ikke uafbrudt, men lige siden.
03:01
We still haven't heard anything.
66
169502
1886
Vi har stadig ikke hørt noget.
03:03
We still haven't heard anything.
67
171388
1678
Vi har stadig ikke hørt noget.
03:05
In fact, we don't know about any life beyond Earth,
68
173066
1793
Vi kender ikke til liv andre steder,
03:06
but I'm going to suggest to you that that's going to change
69
174859
2800
men jeg tror, det vil ændre sig
03:09
rather soon, and part of the reason, in fact,
70
177659
2369
temmelig snart,
og en del af grunden til det...
og en del af grunden til det...
03:12
the majority of the reason why I think that's going to change
71
180028
2775
Ja, størstedelen af grunden, er...
03:14
is that the equipment's getting better.
72
182803
1265
at udstyret bliver bedre.
03:16
This is the Allen Telescope Array, about 350 miles
73
184068
2937
Dette er Allen Telescope Array,
omkring 560 kilometer
omkring 560 kilometer
03:19
from whatever seat you're in right now.
74
187005
2016
fra hvor i sidder lige nu.
03:21
This is something that we're using today
75
189021
2005
Dette er noget, vi bruger i dag
03:23
to search for E.T., and the electronics have gotten
76
191026
2004
til at søge efter E.T.
og elektronikken er
og elektronikken er
03:25
very much better too.
77
193030
1470
også blevet meget bedre.
03:26
This is Frank Drake's electronics in 1960.
78
194500
2526
Dette er Frank Drakes elektronik
tilbage i 1960.

03:29
This is the Allen Telescope Array electronics today.

Dette bruges af
Allen Telescope Array.
Allen Telescope Array.
03:31
Some pundit with too much time on his hands
80
199047
3489
En ekspert med for meget tid
03:34
has reckoned that the new experiments are approximately
81
202536
3007
har regnet ud,
at de nye eksperimenter cirka er
at de nye eksperimenter cirka er
03:37
100 trillion times better than they were in 1960,
82
205543
4495
100 billioner gange bedre
end de var i 1960,
end de var i 1960,
03:42
100 trillion times better.
83
210038
1496
100 billioner gange bedre.
03:43
That's a degree of an improvement that would look good
84
211534
2089
Der er en grad af forbedring
der ville pynte
der ville pynte
03:45
on your report card, okay?
85
213623
2407
i ens karakterbog, ikke?
03:48
But something that's not appreciated by the public is,
86
216030
2634
Men noget, der ikke er værdsat
af offentligheden, er,
af offentligheden, er,
03:50
in fact, that the experiment continues to get better,
87
218664
2725
at eksperimentet stadig bliver bedre.
03:53
and, consequently, tends to get faster.
88
221389
2648
og derfor har tendens
til at blive hurtigere.
til at blive hurtigere.
03:56
This is a little plot, and every time you show a plot,
89
224037
1689
Hver gang man viser
et diagram,
et diagram,
03:57
you lose 10 percent of the audience.
90
225726
1638
mister man 10 % af publikum.
03:59
I have 12 of these. (Laughter)
91
227364
2309
Jeg har 12 af disse. (Latter)
04:01
But what I plotted here is just some metric
92
229673
4420
Men det jeg optegner her
er bare et diagram,
er bare et diagram,
04:06
that shows how fast we're searching.
93
234093
2554
der viser, hvor hurtigt vi søger.
04:08
In other words, we're looking for a needle in a haystack.
94
236647
2108
Vi søger altså nålen i høstakken.
04:10
We know how big the haystack is. It's the galaxy.
95
238755
2287
Vi ved, hvor stor høstakken er.
Det er galaksen.
Det er galaksen.
04:13
But we're going through the haystack no longer
96
241042
2711
Men vi kigger ikke længere gennem den
04:15
with a teaspoon but with a skip loader,
97
243753
2292
med en teske, men med en liftdumper,
04:18
because of this increase in speed.
98
246045
1971
på grund af denne stigning i hastighed.
04:20
In fact, those of you who are still conscious
99
248016
1435
De af jer, der stadig er vågne
04:21
and mathematically competent,
100
249451
2560
og matematisk kompetente, ved -
04:24
will note that this is a semi-log plot.
101
252011
2078
at dette er en
semilogaritmisk afbildning.
semilogaritmisk afbildning.
04:26
In other words, the rate of increase is exponential.
102
254089
4392
Med andre ord
er stigningstakten eksponentiel.
er stigningstakten eksponentiel.
04:30
It's exponentially improving. Now, exponential is an
103
258481
2733
Det forbedres eksponentielt.
Nu er eksponentiel et
Nu er eksponentiel et
04:33
overworked word. You hear it on the media all the time.
104
261214
2319
slidt ord. Man hører det
i medierne hele tiden.
i medierne hele tiden.
04:35
They don't really know what exponential means,
105
263533
1537
De ved ikke,
hvad det betyder,
hvad det betyder,
04:37
but this is exponential.
106
265070
2011
men dette er eksponentielt.
04:39
In fact, it's doubling every 18 months, and, of course,
107
267081
2920
Faktisk fordobles det
hver 18. måned, og, selvfølgelig,
hver 18. måned, og, selvfølgelig,
04:42
every card-carrying member of the digerati knows
108
270001
2004
enhvert kortbærende medlem af digerati ved,
04:44
that that's Moore's Law.
109
272005
1492
at det er Moore's Law.
04:45
So this means that over the course of the next
110
273497
2601
Det betyder, at vi i løbet af
04:48
two dozen years, we'll be able to look at a million star systems,
111
276098
3912
en række år vil være i stand til
at kigge på en million stjernesystemer,
at kigge på en million stjernesystemer,
04:52
a million star systems, looking for signals
112
280010
2028
for at se på tegn,
04:54
that would prove somebody's out there.
113
282038
1509
der beviser liv derude.
04:55
Well, a million star systems, is that interesting?
114
283547
2498
En million stjernesystemer,
er det interessant?
er det interessant?
04:58
I mean, how many of those star systems have planets?
115
286045
3014
Hvor mange af de stjernesystemer
har planeter?
har planeter?
05:01
And the facts are, we didn't know the answer to that
116
289059
2145
Og faktum er,
det vidste vi ikke
det vidste vi ikke
05:03
even as recently as 15 years ago, and in fact, we really
117
291204
2774
for selv 15 år siden, og ej heller
05:05
didn't know it even as recently as six months ago.
118
293978
2523
for blot seks måneder siden.
05:08
But now we do. Recent results suggest
119
296501
2878
Men det ved vi nu.
Nylige resultater indikerer,
Nylige resultater indikerer,
05:11
that virtually every star has planets, and more than one.
120
299379
3639
at faktisk alle stjerne har planeter,
og mere end én.
og mere end én.
05:15
They're like, you know, kittens. You get a litter.
121
303018
3326
Det er ligesom killinger.
Man får et kuld.
Man får et kuld.
05:18
You don't get one kitten. You get a bunch.
122
306344
1740
Man får ikke én.
Man får mange.
Man får mange.
05:20
So in fact, this is a pretty accurate estimate
123
308084
2934
Det er faktisk et temmelig nøjagtigt skøn
05:23
of the number of planets in our galaxy,
124
311018
3996
på antallet af planeter i vores galakse,
05:27
just in our galaxy, by the way,
125
315014
2027
kun i vores galakse, for øvrigt,
05:29
and I remind the non-astronomy majors among you
126
317041
2770
og jeg vil minde de
ikke-astronomstuderende om,
ikke-astronomstuderende om,
05:31
that our galaxy is only one of 100 billion
127
319811
2245
at vores galakse
kun er én ud af 100 milliarder
kun er én ud af 100 milliarder
05:34
that we can see with our telescopes.
128
322056
1984
der kan ses med vores teleskoper.
05:36
That's a lot of real estate, but of course,
129
324040
1523
Det er meget fast ejendom, men
05:37
most of these planets are going to be kind of worthless,
130
325563
1909
de fleste planer er temmelig værdiløse,
05:39
like, you know, Mercury, or Neptune.
131
327472
2092
som f.eks. Merkur, eller Neptun.
05:41
Neptune's probably not very big in your life.
132
329564
2090
Neptun er nok ikke så stor i jeres liv.
05:43
So the question is, what fraction of these planets
133
331654
4347
Så spørgmålet er,
hvilken del af disse planeter
hvilken del af disse planeter
05:48
are actually suitable for life?
134
336001
1682
er faktisk egnet til liv?
05:49
We don't know the answer to that either,
135
337683
1405
Det ved vi heller ikke,
05:51
but we will learn that answer this year, thanks to
136
339088
2238
men det kommer vi til i år,
takket være
takket være
05:53
NASA's Kepler Space Telescope,
137
341326
1756
NASAs Keplerteleskopet.
05:55
and in fact, the smart money, which is to say the people who work on this project,
138
343082
4022
Et fornuftigt gæt,
altså folkene, der arbejder på projektet,
altså folkene, der arbejder på projektet,
05:59
the smart money is suggesting that the fraction of planets
139
347104
3429
er at foreslå, at den del af planeter,
06:02
that might be suitable for life is maybe one in a thousand,
140
350533
4036
der muligvis er egnede til liv,
måske er én ud af tusinde,
måske er én ud af tusinde,
06:06
one in a hundred, something like that.
141
354569
3307
én ud af hundrede, noget i den stil.
06:09
Well, even taking the pessimistic estimate, that it's
142
357876
2140
Selv hvis vi giver et pessimistisk skøn,
06:12
one in a thousand, that means that there are
143
360016
3111
som én ud af tusinde,
betyder det, at der er
betyder det, at der er
06:15
at least a billion cousins of the Earth
144
363127
2529
minimum en milliard slægtning til jorden
06:17
just in our own galaxy.
145
365656
1727
bare i vores egen galakse.
06:19
Okay, now I've given you a lot of numbers here,
146
367383
2253
Okay, nu har jeg givet jer en masse tal,
06:21
but they're mostly big numbers, okay, so, you know,
147
369636
3926
men det er mest store tal,
06:25
keep that in mind. There's plenty of real estate,
148
373562
2479
Det er masser af fast ejendom,
06:28
plenty of real estate in the universe,
149
376041
2013
masser af fast ejendom i universet,
06:30
and if we're the only bit of real estate in which there's
150
378054
2949
og hvis vi besidder det eneste stykke
fast ejendom, hvor der er
fast ejendom, hvor der er
06:33
some interesting occupants, that makes you a miracle,
151
381003
3035
interessante beboere,
gør det os til mirakler.
gør det os til mirakler.
06:36
and I know you like to think you're a miracle,
152
384038
2681
Jeg ved, i gerne vil opfatte
jer selv som mirakler,
jer selv som mirakler,
06:38
but if you do science, you learn rather quickly that
153
386719
1910
men er man forsker, lærer man
06:40
every time you think you're a miracle, you're wrong,
154
388629
1883
at man ofte tager fejl.
06:42
so probably not the case.
155
390512
2528
Så det er nok ikke tilfældet.
06:45
All right, so the bottom line is this:
156
393040
2051
Okay, så det, der tæller, er følgende:
06:47
Because of the increase in speed, and because of the
157
395091
2963
På grund af stigningen i hastighed,
og på grund af den
og på grund af den
06:50
vast amount of habitable real estate in the cosmos, I figure
158
398054
4951
enorme mængde beboelig fast ejendom
i kosmos, regner jeg med,
i kosmos, regner jeg med,
06:55
we're going to pick up a signal within two dozen years.
159
403005
2045
at vi finder et signal
inden for en årrække.
inden for en årrække.
06:57
And I feel strongly enough about that to make a bet with you:
160
405050
2971
Og derfor er jeg villig til
at indgå et væddemål med jer:
at indgå et væddemål med jer:
07:00
Either we're going to find E.T. in the next two dozen years,
161
408021
2437
Enten finder vi E.T.
i løbet af en årrække,
i løbet af en årrække,
07:02
or I'll buy you a cup of coffee.
162
410458
3618
eller også køber jeg en kop kaffe.
07:06
So that's not so bad. I mean, even with two dozen years,
163
414076
2634
Det er ikke så dårligt.
Om en række år
Om en række år
07:08
you open up your browser and there's news of a signal,
164
416710
1859
finder man enten nyt om
et signal,
et signal,
07:10
or you get a cup of coffee.
165
418569
1751
eller man får en kop kaffe.
07:12
Now, let me tell you about some aspect of this that
166
420320
3973
Lad mig fortælle jer om
et aspekt af dette, som
et aspekt af dette, som
07:16
people don't think about, and that is,
167
424293
2038
folk ikke tænker over:
07:18
what happens? Suppose that what I say is true.
168
426331
3708
Hvad sker der?
Lad os sige, at det, jeg siger, er sandt.
Lad os sige, at det, jeg siger, er sandt.
07:22
I mean, who knows, but suppose it happens.
169
430039
2365
Hvad nu, hvis det skete?
07:24
Suppose some time in the next two dozen years
170
432404
1487
Hvis vi i løbet af en række år
07:25
we pick up a faint line that tells us
171
433891
2177
finder et svagt signal, der fortæller os,
07:28
we have some cosmic company.
172
436068
1688
at vi har kosmisk selskab.
07:29
What is the effect? What's the consequence?
173
437756
2295
Hvad er effekten? Hvad er konsekvensen?
07:32
Now, I might be at ground zero for this.
174
440051
1964
Jeg har måske ramt noget her.
07:34
I happen to know what the consequence for me would be,
175
442015
1821
Jeg ved, hvad følgerne ville være,
07:35
because we've had false alarms. This is 1997,
176
443836
2909
for vi har haft falske alarmer.
Dette er 1997:
Dette er 1997:
07:38
and this is a photo I made at about 3 o'clock in the morning
177
446760
2284
Jeg tog dette billede
cirka klokken 3 om natten
cirka klokken 3 om natten
07:41
in Mountain View here, when we were watching
178
449044
2009
her i Mountain View, da vi kiggede på
07:43
the computer monitors because we had picked up a signal
179
451053
2315
computerskærmene,
fordi vi havde et signal,
fordi vi havde et signal,
07:45
that we thought, "This is the real deal." All right?
180
453368
3078
hvor vi troede,
"Dette er den ægte vare." Okay?
"Dette er den ægte vare." Okay?
07:48
And I kept waiting for the Men in Black to show up. Right?
181
456446
3368
Og jeg blev ved med at vente på
at Men in Black dukkede op. Ikke?
at Men in Black dukkede op. Ikke?
07:51
I kept waiting for -- I kept waiting for my mom to call,
182
459814
4203
Jeg ventede på...
at min mor skulle ringe,
at min mor skulle ringe,
07:56
somebody to call, the government to call. Nobody called.
183
464017
3004
at nogen ringede,
at regeringen ringede. Ingen ringede.
at regeringen ringede. Ingen ringede.
07:59
Nobody called. I was so nervous
184
467021
3170
Ingen ringede. Jeg var så nervøs.
08:02
that I couldn't sit down. I just wandered around
185
470191
1824
Jeg kunne ikke finde ro og gik rundt
08:04
taking photos like this one, just for something to do.
186
472015
2990
og tog de her billeder,
bare for at have noget at lave.
bare for at have noget at lave.
08:07
Well, at 9:30 in the morning, with my head down
187
475005
2034
Klokken 09.30 om morgenen,
med hovedet nede
med hovedet nede
08:09
on my desk because I obviously hadn't slept all night,
188
477039
2030
på bordet, fordi jeg ikke
havde sovet,
havde sovet,
08:11
the phone rings and it's The New York Times.
189
479069
2337
ringede telefonen.
Det var New York Times.
Det var New York Times.
08:13
And I think there's a lesson in that, and that lesson is
190
481406
2626
Og hvad kan man så lære af det?
08:16
that if we pick up a signal, the media, the media will be on it
191
484032
2980
Fanger man et signal,
kaster medierne sig over det
kaster medierne sig over det
08:19
faster than a weasel on ball bearings. It's going to be fast.
192
487012
4334
hurtigere, end man kan tælle til ti.
Altså, meget hurtigt.
Altså, meget hurtigt.
08:23
You can be sure of that. No secrecy.
193
491346
1678
Ingen hemmelighedskræmmeri.
08:25
That's what happens to me. It kind of ruins my whole week,
194
493024
2983
Det ødelægger på en eller anden måde
hele min uge,
hele min uge,
08:28
because whatever I've got planned that week is kind of out the window.
195
496007
2623
for alt, jeg har planlagt,
ryger i vasken.
ryger i vasken.
08:30
But what about you? What's it going to do to you?
196
498630
2420
Men hvad med jer?
Hvad ville det gøre for jer?
Hvad ville det gøre for jer?
08:33
And the answer is that we don't know the answer.
197
501050
2007
Og svaret er, at vi ikke kender svaret.
08:35
We don't know what that's going to do to you,
198
503057
885
Vi ved det ikke.
08:35
not in the long term, and not even very much in the short term.
199
503942
3124
Hverken på lang eller kort sigt.
08:39
I mean, that would be a bit like
200
507066
2828
Jeg mener, det ville være lidt ligesom
08:41
asking Chris Columbus in 1491, "Hey Chris,
201
509894
3106
at spørge Chris Columbus i 1491:
"Hey Chris,
"Hey Chris,
08:45
you know, what happens if it turns out that there's a
202
513000
2014
hvad sker der, hvis der viser sig et
08:47
continent between here and Japan, where you're sailing to,
203
515014
3536
kontinent mellem her og Japan,
hvor du sejler hen?
hvor du sejler hen?
08:50
what will be the consequences for humanity
204
518550
2775
hvad vil konsekvensen da være
for menneskeheden,
for menneskeheden,
08:53
if that turns out to be the case?"
205
521325
1746
hvis det viser sig at være sandt?"
08:55
And I think Chris would probably offer you some answer
206
523071
2230
Og Chris vil nok give jer et svar
08:57
that you might not have understood, but it probably
207
525301
2711
som i nok ikke ville forstå,
men det havde sikkert
men det havde sikkert
09:00
wouldn't have been right, and I think that to predict
208
528012
2834
ikke været rigtigt, og jeg tror det,
at forudsige
at forudsige
09:02
what finding E.T.'s going to mean,
209
530846
1759
hvad det vil betyde at finde E.T.
09:04
we can't predict that either.
210
532605
1080
heller ikke går.
09:05
But here are a couple things I can say.
211
533685
1622
Men det her kan jeg dog sige:
09:07
To begin with, it's going to be a society that's way in advance of our own.
212
535307
4157
Til en start vil det være et samfund
meget mere avanceret end vores eget.
meget mere avanceret end vores eget.
09:11
You're not going to hear from alien Neanderthals.
213
539464
1624
Ikke fremmedartede Neandertalere.
09:13
They're not building transmitters.
214
541088
1290
De bygger ikke radiosendere.
09:14
They're going to be ahead of us, maybe by a few thousand
215
542378
1926
De vil være foran os, måske tusinder af
09:16
years, maybe by a few millions years, but substantially
216
544304
3067
år, måske med et par millioner år,
men betydeligt
men betydeligt
09:19
ahead of us, and that means, if you can understand
217
547371
2229
foran os, og det betyder,
at vil man kan forstå
at vil man kan forstå
09:21
anything that they're going to say, then you might be able
218
549600
3786
noget af det, de siger,
vil man måske være
vil man måske være
09:25
to short-circuit history by getting information from a society
219
553386
3090
i stand til at omgå historien
ved at få information fra et samfund,
ved at få information fra et samfund,
09:28
that's way beyond our own.
220
556476
1574
der er meget længere fremme.
09:30
Now, you might find that a bit hyperbolic, and maybe it is,
221
558050
2951
I finder det måske en smule overdrevent,
og det er det måske,
og det er det måske,
09:33
but nonetheless, it's conceivable that this will happen,
222
561001
2653
men det kan dog ske.
09:35
and, you know, you could consider this like, I don't know,
223
563654
2373
Man kunne sige, det er,
09:38
giving Julius Caesar English lessons and the key
224
566027
2469
som at give Cæsar engelskundervisning
og nøglen til
og nøglen til
09:40
to the library of Congress.
225
568496
1107
Library of Congress.
09:41
It would change his day, all right?
226
569603
2455
Det ville ændre hans dag, ikke?
09:44
That's one thing. Another thing that's for sure
227
572058
1995
En anden ting, der helt sikkert
09:46
going to happen is that it will calibrate us.
228
574053
3500
vil komme til at ske, er,
at det vil kalibrere os.
at det vil kalibrere os.
09:49
We will know that we're not that miracle, right,
229
577553
3938
Vi får vished om,
at vi ikke er et mirakel,
at vi ikke er et mirakel,
09:53
that we're just another duck in a row,
230
581491
1562
men bare endnu et nummer i rækken.
09:55
we're not the only kids on the block, and I think that that's
231
583053
1995
Vi er ikke de eneste børn i kvarteret.
09:57
philosophically a very profound thing to learn.
232
585048
2954
Filosofisk set er det
en meget dybsindig ting at lære.
en meget dybsindig ting at lære.
10:00
We're not a miracle, okay?
233
588002
3101
Vi er ikke noget mirakel, okay?
10:03
The third thing that it might tell you is somewhat vague,
234
591103
3299
Den tredje ting, det måske fortæller en,
er temmelig uklart,
er temmelig uklart,
10:06
but I think interesting and important,
235
594402
2123
men jeg mener,
det er interessant og vigtigt:
det er interessant og vigtigt:
10:08
and that is, if you find a signal coming from a more
236
596525
2105
Fanger man et signal,
der kommer fra et mere
der kommer fra et mere
10:10
advanced society, because they will be,
237
598630
2231
avanceret samfund, for det vil det være,
10:12
that will tell you something about our own possibilities,
238
600861
2652
vil det fortælle noget
om vores egne muligheder,
om vores egne muligheder,
10:15
that we're not inevitably doomed to self-destruction.
239
603513
4782
at vi ikke er dødsdømte
til selvødelæggelse.
til selvødelæggelse.
10:20
Because they survived their technology,
240
608295
1796
For hvis de overlevede deres teknologi,
10:22
we could do it too.
241
610091
1112
kan vi også gøre det.
10:23
Normally when you look out into the universe,
242
611203
1891
Når man plejer at kigge ud i universet,
10:25
you're looking back in time. All right?
243
613094
2461
ser man tilbage i tiden. Okay?
10:27
That's interesting to cosmologists.
244
615555
2039
Det er interessant for kosmologer.
10:29
But in this sense, you actually can look into the future,
245
617594
3444
Men på denne måde,
kan man faktisk se ud i fremtiden,
kan man faktisk se ud i fremtiden,
10:33
hazily, but you can look into the future.
246
621038
2015
vagt, men man kan se ud i fremtiden.
10:35
So those are all the sorts of things that would come from a detection.
247
623053
5537
Det er den slags ting,
der vil komme fra en opdagelse.
der vil komme fra en opdagelse.
10:40
Now, let me talk a little bit about something that happens
248
628590
2432
Lad mig tale lidt om noget der sker
10:43
even in the meantime, and that is,
249
631022
4212
i mellemtiden.
10:47
SETI, I think, is important, because it's exploration, and
250
635234
4778
SETI, synes jeg, er vigtig,
fordi det er udforskning, og,
fordi det er udforskning, og,
10:52
it's not only exploration, it's comprehensible exploration.
251
640012
2452
ikke kun udforskning,
men forståelig udforskning.
men forståelig udforskning.
10:54
Now, I gotta tell you, I'm always reading books about
252
642464
2865
Jeg læser altid bøger om
10:57
explorers. I find exploration very interesting,
253
645329
2715
opdagelsesrejsende. Jeg finder
det meget interessant.
det meget interessant.
11:00
Arctic exploration, you know, people like Magellan,
254
648044
2981
Arktisk udforskning. Mennesker som Magellan,
11:03
Amundsen, Shackleton, you see Franklin down there,
255
651025
2996
Åmundsen, Shackleton,
man kan se Franklin dernede,
man kan se Franklin dernede,
11:06
Scott, all these guys. It's really nifty, exploration.
256
654021
3324
Scott, dem alle.
Det er virkelig dygtig udforskning.
Det er virkelig dygtig udforskning.
11:09
And they're just doing it because they want to explore,
257
657345
2239
Og de gør det kun, fordi de vil udforske.
11:11
and you might say, "Oh, that's kind of a frivolous opportunity,"
258
659584
2116
og man siger måske,
"Hvor ligegyldigt!"
"Hvor ligegyldigt!"
11:13
but that's not frivolous. That's not a frivolous activity,
259
661700
3328
men det er ikke ligegyldigt.
Det er ikke en ligegyldig aktivitet,
Det er ikke en ligegyldig aktivitet,
11:17
because, I mean, think of ants.
260
665028
2031
Tænk bare på myrer.
11:19
You know, most ants are programmed to follow one another
261
667059
1997
De er skabt til at følge efter hinanden
11:21
along in a long line, but there are a couple of ants,
262
669056
2248
i en lang række, men der er et par myrer,
11:23
maybe one percent of those ants, that are what they call
263
671304
2696
måske en procent af de myrer,
dem, man kalder
dem, man kalder
11:26
pioneer ants, and they're the ones that wander off.
264
674000
2175
pioner myrer, der vandrer afsted.
11:28
They're the ones you find on the kitchen countertop.
265
676175
1901
Det er dem,
man finder i køkkenet.
man finder i køkkenet.
11:30
You gotta get them with your thumb before they
266
678076
1998
Man skal fange dem med fingeren,
før de
før de
11:32
find the sugar or something.
267
680074
1584
finder sukker, eller noget.
11:33
But those ants, even though most of them get wiped out,
268
681658
2405
Men de myrer,
skønt de fleste bliver dræbt,
skønt de fleste bliver dræbt,
11:36
those ants are the ones that are essential to the survival
269
684063
3292
er essentielle for overlevelse
11:39
of the hive. So exploration is important.
270
687355
3574
af tuen. Så udforskning er vigtigt.
11:42
I also think that exploration is important in terms of
271
690929
3380
Jeg mener også, at udforskning er vigtigt
med hensyn til
med hensyn til
11:46
being able to address what I think is a critical
272
694309
4870
at kunne udtrykke det, jeg mener,
er en kritisk
er en kritisk
11:51
lack in our society, and that is the lack of science literacy,
273
699179
3201
mangelvare i vores samfund:
Videnskabelig kompetence.
Videnskabelig kompetence.
11:54
the lack of the ability to even understand science.
274
702380
3643
Manglende evnen til selv
at forstå videnskab.
at forstå videnskab.
11:58
Now, look, a lot has been written about the
275
706023
2042
Hør engang. Meget er blevet skrevet om den
12:00
deplorable state of science literacy in this country.
276
708065
3398
videnskabelige kompetences sørgelige
tilstand her i landet.
tilstand her i landet.
12:03
You've heard about it.
277
711463
2552
I har hørt om det.
12:06
Well, here's one example, in fact.
278
714015
2052
Der er faktisk et eksempel.
12:08
Polls taken, this poll was taken 10 years ago.
279
716067
2319
Meningsmålinger, denne her lavet
for 10 år siden,
for 10 år siden,
12:10
It shows like roughly one third of the public thinks
280
718386
2129
viser, at ca. en tredjedel mener,
12:12
that aliens are not only out there, we're looking for them
281
720515
1964
at rumvæsener ikke kun er derude,
12:14
out there, but they're here, right?
282
722479
1618
men at de er her, ikke?
12:16
Sailing the skies in their saucers and occasionally
283
724097
2299
De flyver rundt i deres UFOer
og bortfører
og bortfører
12:18
abducting people for experiments their parents wouldn't approve of.
284
726396
3116
folk til eksperimenter,
deres forældre ikke ville give lov til.
deres forældre ikke ville give lov til.
12:21
Well, that would be interesting if it was true,
285
729512
3173
Jamen, det ville være interessant,
hvis det var sandt.
hvis det var sandt.
12:24
and job security for me, but I don't think the evidence is
286
732685
1879
Sikkert job til mig!
Men beviserne er
Men beviserne er
12:26
very good. That's more, you know, sad than significant.
287
734564
3472
ikke gode. Det er mere
sørgelige end vigtige.
sørgelige end vigtige.
12:30
But there are other things that people believe
288
738036
2019
Men der er andre ting, som folk tror på,
12:32
that are significant, like the efficacy of homeopathy,
289
740055
3411
der er vigtige, som effekten af homøopati.
12:35
or that evolution is just, you know, sort of a crazy idea
290
743466
3551
Eller at evolutionen bare er en fiks idé
12:39
by scientists without any legs, or, you know, evolution,
291
747017
3031
hos forskere uden ben, eller, evolution,
12:42
all that sort of thing, or global warming.
292
750048
2556
den slags ting, eller global opvarmning.
12:44
These sorts of ideas don't really have any validity,
293
752604
3401
Den slags ideer har i virkeligheden
ikke nogen validitet,
ikke nogen validitet,
12:48
that you can't trust the scientists.
294
756005
2075
at man ikke kan stole på forskere.
12:50
Now, we've got to solve that problem, because that's
295
758080
2243
Det er et problem vi skal løse,
fordi det er
fordi det er
12:52
a critically important problem, and you might say,
296
760323
4078
et vigtigt problem,
og man kunne sige,
og man kunne sige,
12:56
"Well, okay, how are we gonna solve that problem with SETI?"
297
764401
2629
"Hvordan skal vi løse
det problem med SETI?"
det problem med SETI?"
12:59
Well, let me suggest to you that SETI obviously can't
298
767030
2399
Jamen, lad mig sige,
at SETI absolut ikke kan
at SETI absolut ikke kan
13:01
solve the problem, but it can address the problem.
299
769429
1663
løse det, blot tage
hånd om det.
hånd om det.
13:03
It can address the problem by getting young people
300
771092
2943
Det kan tage hånd om problemet
ved at få unge mennesker
ved at få unge mennesker
13:06
interested in science. Look, science is hard, it
301
774035
2998
til at blive interesseret i videnskab.
Videnskab er svært.
Videnskab er svært.
13:09
has a reputation of being hard, and the facts are, it is hard,
302
777033
3053
Sådan rygtes det, ihvertfald.
Og faktum er, at det er svært,
Og faktum er, at det er svært,
13:12
and that's the result of 400 years of science, right?
303
780086
4935
og det er resultatet
af 400 års videnskab, ikke?
af 400 års videnskab, ikke?
13:17
I mean, in the 18th century, in the 18th century
304
785021
2479
I det 18. århundrede
13:19
you could become an expert on any field of science
305
787500
2590
kunne man blive ekspert
på ethvert videnskabsområde
på ethvert videnskabsområde
13:22
in an afternoon by going to a library,
306
790090
2914
på en eftermiddag
ved at gå på biblioteket,
ved at gå på biblioteket,
13:25
if you could find the library, right?
307
793004
2021
hvis man kunne finde biblioteket, ikke?
13:27
In the 19th century, if you had a basement lab,
308
795025
3616
I det 19. århundrede,
hvis man havde et laboratorium i kælderen,
hvis man havde et laboratorium i kælderen,
13:30
you could make major scientific discoveries
309
798641
2747
kunne man gøre
kæmpestore videnskabelige opdagelser
kæmpestore videnskabelige opdagelser
13:33
in your own home. Right? Because there was all this
310
801388
2225
i ens eget hjem.
Fordi der var al den
Fordi der var al den
13:35
science just lying around waiting for somebody to pick it up.
311
803613
2875
videnskab, der bare ventede på,
at nogen samlede det op.
at nogen samlede det op.
13:38
Now, that's not true anymore.
312
806488
1593
Det er ikke sandt mere.
13:40
Today, you've got to spend years in grad school
313
808081
2428
I dag skal man bruge flere år
på universitetet
på universitetet
13:42
and post-doc positions just to figure out what
314
810509
3498
og Ph.d. stillinger bare for
at finde ud af, hvad
at finde ud af, hvad
13:46
the important questions are.
315
814007
2056
de vigtige spørgsmål er.
13:48
It's hard. There's no doubt about it.
316
816063
1995
Det er svært. Det er der ingen tvivl om.
13:50
And in fact, here's an example: the Higgs boson,
317
818058
2309
Og faktisk er dette et eksempel:
Higgs-partiklen,
Higgs-partiklen,
13:52
finding the Higgs boson.
318
820367
1909
at finde Higgs-partiklen.
13:54
Ask the next 10 people you see on the streets,
319
822276
1800
Spørg de næste 10 mennesker
i møder:
i møder:
13:56
"Hey, do you think it's worthwhile to spend billions
320
824076
2338
"Hej, synes du,
det er iorden at bruge milliarder
det er iorden at bruge milliarder
13:58
of Swiss francs looking for the Higgs boson?"
321
826414
2641
schweiziske francs på at lede
efter Higgs-partiklen?"
efter Higgs-partiklen?"
14:01
And I bet the answer you're going to get, is,
322
829055
2321
Og jeg vil væde med at svaret er:
14:03
"Well, I don't know what the Higgs boson is,
323
831376
1657
"Jeg ved ikke, hvad det er,
14:05
and I don't know if it's important."
324
833033
1232
eller om det er vigtigt."
14:06
And probably most of the people wouldn't even know
325
834265
1799
Og de fleste ved sikkert ikke
14:08
the value of a Swiss franc, okay?
326
836064
2447
hvad værdien
af en schweizisk franc er, vel?
af en schweizisk franc er, vel?
14:10
And yet we're spending billions of Swiss francs on this problem.
327
838511
2530
Og alligevel bruger vi milliarder
på dette problem.
på dette problem.
14:13
Okay? So that doesn't get people interested in science
328
841041
2153
Mennesker interesserer sig ikke
for videnskab,
for videnskab,
14:15
because they can't comprehend what it's about.
329
843194
1876
når de ikke aner,
hvad det går ud på.
hvad det går ud på.
14:17
SETI, on the other hand, is really simple.
330
845070
1617
SETI er dog meget simpel.
14:18
We're going to use these big antennas and we're going to
331
846687
1616
Vi vil bruge disse store antenner
14:20
try to eavesdrop on signals. Everybody can understand that.
332
848303
2752
og prøve at lytte efter signaler.
Alle kan forstå det.
Alle kan forstå det.
14:23
Yes, technologically, it's very sophisticated,
333
851055
2009
Teknologisk set
er det meget sofistikeret,
er det meget sofistikeret,
14:25
but everybody gets the idea.
334
853064
2006
men alle forstår ideen.
14:27
So that's one thing. The other thing is, it's exciting science.
335
855070
3938
Den anden ting er,
at det er spændende videnskab.
at det er spændende videnskab.
14:31
It's exciting because we're naturally interested
336
859008
2414
Fordi vi naturligt er interesserede
14:33
in other intelligent beings, and I think that's
337
861422
2225
i andre intelligente væsner.
14:35
part of our hardwiring.
338
863647
1424
Sådan er vi bygget op.
14:37
I mean, we're hardwired to be interested
339
865071
1560
Skabt til at have interesse
14:38
in beings that might be, if you will, competitors,
340
866631
2801
for væsner, der kunne være konkurrenter,
om man vil.
om man vil.
14:41
or if you're the romantic sort, possibly even mates. Okay?
341
869432
3583
eller, er man optimistisk,
måske endda kammerater.
måske endda kammerater.
14:45
I mean, this is analogous to our interest in things that
342
873015
2011
Dette er parallelt
med vores interesse
med vores interesse
14:47
have big teeth. Right?
343
875026
2021
for det med store tænder.
14:49
We're interested in things that have big teeth, and you
344
877047
1474
Vi forsker i store tænder,
14:50
can see the evolutionary value of that, and you can also see
345
878521
2545
og du kan se den evolutionære værdi.
Du kan også
Du kan også
14:53
the practical consequences by watching Animal Planet.
346
881066
3688
se de praktiske konsekvenser,
når du ser Animal Planet.
når du ser Animal Planet.
14:56
You notice they make very few programs about gerbils.
347
884754
2334
F.eks. laver de få programmer
om ørkenrotter.
om ørkenrotter.
14:59
It's mostly about things that have big teeth.
348
887088
2056
Mest om ting med store tænder.
15:01
Okay, so we're interested in these sorts of things.
349
889144
2947
Så vi er interesserede i de her ting.
15:04
And not just us. It's also kids.
350
892091
3935
Og ikke kun os. Det er også børn.
15:08
This allows you to pay it forward by using this subject as a
351
896026
3427
Man kan altså give det videre
ved at bruge emnet som
ved at bruge emnet som
15:11
hook to science, because SETI involves all kinds of science,
352
899453
3232
en forbindelse til videnskab,
fordi SETI inddrager mange slags emner
fordi SETI inddrager mange slags emner
15:14
obviously biology, obviously astronomy,
353
902685
1990
Selvfølgelig biologi og astronomi,
15:16
but also geology, also chemistry, various scientific
354
904675
3334
men også geologi, kemi...
Forskellige videnskabelige
Forskellige videnskabelige
15:20
disciplines all can be presented in the guise of,
355
908009
4000
discipliner, der alle kan
præsenteres under overskriften:
præsenteres under overskriften:
15:24
"We're looking for E.T."
356
912009
1329
"Vi leder efter E.T."
15:25
So to me this is interesting and important, and in fact,
357
913338
4457
For mig er dette interessant og vigtigt,
og faktisk,
og faktisk,
15:29
it's my policy, even though I give a lot of talks to adults,
358
917795
3238
er det mit mål, selvom jeg holder
mange foredrag for voksne.
mange foredrag for voksne.
15:33
you give talks to adults, and two days later they're back where they were.
359
921033
2668
To dage senere er de dog tilbage
ved udgangspunktet.
ved udgangspunktet.
15:35
But if you give talks to kids, you know,
360
923701
2922
Men hvis man holder foredrag for børn,
15:38
one in 50 of them, some light bulb goes off, and they think,
361
926623
4152
tændes en pære i én ud af 50,
og de tænker,
og de tænker,
15:42
"Gee, I'd never thought of that," and then they go,
362
930775
1801
"Nøj, det har jeg aldrig tænkt på."
15:44
you know, read a book or a magazine or whatever.
363
932576
1792
Og så læser de en masse om det.
15:46
They get interested in something.
364
934368
1682
De bliver interesserede i noget.
15:48
Now it's my theory, supported only by anecdotal,
365
936050
4974
Okay, så det er min teori,
kun understøttet af anekdoter,
kun understøttet af anekdoter,
15:53
personal anecdotal evidence, but nonetheless,
366
941024
2023
men ikke desto mindre,
15:55
that kids get interested in something between the ages
367
943047
2473
at børn bliver interesserede i noget,
når de er
når de er
15:57
of eight and 11. You've got to get them there.
368
945520
2536
mellem 8 og 11.
Det er der, man skal have fat i dem.
Det er der, man skal have fat i dem.
16:00
So, all right, I give talks to adults, that's fine, but I try
369
948056
2620
Det er fint at holde foredrag for voksne,
men jeg prøver
men jeg prøver
16:02
and make 10 percent of the talks that I give,
370
950676
2325
at holde 10 % af dem...
16:05
I try and make those for kids.
371
953001
2077
Jeg prøver at holde dem for børn.
16:07
I remember when a guy came to our high school, actually,
372
955078
2976
Jeg kan huske den her fyr i skolen...
16:10
it was actually my junior high school. I was in sixth grade.
373
958054
2976
i 6. klasse.
16:13
And he gave some talk. All I remember from it
374
961030
2480
Han holdt et foredrag. Alt, jeg husker,
16:15
was one word: electronics.
375
963510
1575
er et ord: elektronik.
16:17
It was like Dustin Hoffman in "The Graduate," right,
376
965085
2561
Det var som Dustin Hoffman
i "Fagre voksne verden,"
i "Fagre voksne verden,"
16:19
when he said "plastics," whatever that means, plastics.
377
967646
2398
da han sagde "plastik".
16:22
All right, so the guy said electronics. I don't remember
378
970044
1995
Fyren sagde elektronik.
Jeg husker ikke
Jeg husker ikke
16:24
anything else. In fact, I don't remember anything
379
972039
2004
andet end det. Faktisk husker jeg ikke,
16:26
that my sixth grade teacher said all year,
380
974043
2010
hvad min lærer ellers sagde hele året,
16:28
but I remember electronics.
381
976053
2014
men jeg kan huske elektronik.
16:30
And so I got interested in electronics, and you know,
382
978067
2652
Så jeg blev interesseret i elektronik,
16:32
I studied to get my ham license. I was wiring up stuff.
383
980719
2325
jeg studerede for at få
amatørradio tilladelse.
amatørradio tilladelse.
16:35
Here I am at about 15 or something, doing that sort of stuff.
384
983044
2978
Som ca. 15-årig,
laver jeg altså den slags ting.
laver jeg altså den slags ting.
16:38
Okay? That had a big effect on me.
385
986022
1583
Det havde stor indflydele på mig.
16:39
So that's my point, that you can have a big effect
386
987605
1712
Man kan altså have stor indflydelse
16:41
on these kids.
387
989317
2716
på disse børn.
16:44
In fact, this reminds me, I don't know, a couple years ago
388
992033
3661
Faktisk minder det mig om,
at jeg for et par år siden
at jeg for et par år siden
16:47
I gave a talk at a school in Palo Alto
389
995694
3326
holdt et foredrag ved en skole i Palo Alto
16:51
where there were about a dozen 11-year-olds
390
999020
2013
hvor der var en flok 11 årige
16:53
that had come to this talk.
391
1001033
972
til foredraget.
16:54
I had been brought in to talk to these kids for an hour.
392
1002005
2516
Jeg skulle tale med børnene i en time.
16:56
Eleven-year-olds, they're all sitting in a little semi-circle
393
1004521
2274
Elleve årige, siddende
i en lille halvcirkel,
i en lille halvcirkel,
16:58
looking up at me with big eyes, and I started,
394
1006795
2244
der kigger op på mig med store øjne.
17:01
there was a white board behind me, and I started off
395
1009039
1656
Der var en tavle,
og jeg skrev
og jeg skrev
17:02
by writing a one with 22 zeroes after it, and I said,
396
1010695
2838
et et-tal med 22 nuller bagefter og sagde:
17:05
"All right, now look, this is the number of stars
397
1013533
2363
"Okay, ser her,
det her er det antal stjerner
det her er det antal stjerner
17:07
in the visible universe, and this number is so big
398
1015896
2872
i det synlige univers,
og tallet er så stort
og tallet er så stort
17:10
there's not even a name for it."
399
1018768
3348
at der ikke engang er et navn for det."
17:14
And one of these kids shot up his hand, and he said,
400
1022116
2465
Og et af disse børn
rakte hånden op og sagde:
rakte hånden op og sagde:
17:16
"Well, actually there is a name for it.
401
1024581
1505
"Der et navn for det.
17:18
It's a sextra-quadra-hexa-something or other." Right?
402
1026086
2934
Det er et sextra-quadra-hexa
eller sådan noget"
eller sådan noget"
17:21
Now, that kid was wrong by four orders of magnitude,
403
1029020
3996
Nu tog det barn fejl
i kæmpestor størrelsesorden,
i kæmpestor størrelsesorden,
17:25
but there was no doubt about it, these kids were smart.
404
1033016
2472
men de her børn var helt sikkert kloge.
17:27
Okay? So I stopped giving the lecture.
405
1035488
1968
Så jeg stoppede med foredraget.
17:29
All they wanted to do was ask questions.
406
1037456
2583
De ville bare stille spørgsmål.
17:32
In fact, my last comments to these kids, at the end I said,
407
1040039
3992
Min sidste kommentar til dem var:
17:36
"You know, you kids are smarter
408
1044031
2032
"Ved I hvad, I børn er klogere
17:38
than the people I work with." Now — (Laughter)
409
1046063
4942
end de folk,
jeg arbejder med." Men -- (Latter)
jeg arbejder med." Men -- (Latter)
17:43
They didn't even care about that.
410
1051005
1329
Det var de ligeglade med.
17:44
What they wanted was my email address
411
1052334
2694
De ville have min email adresse.
17:47
so they could ask me more questions. (Laughter)
412
1055028
3985
Så de kunne stille
flere spørgsmål. (Latter)
flere spørgsmål. (Latter)
17:51
Let me just say, look, my job is a privilege
413
1059013
3159
Jeg har et privilegeret job,
17:54
because we're in a special time.
414
1062172
1623
fordi vi lever i en speciel tid.
17:55
Previous generations couldn't do this experiment at all.
415
1063795
2785
Tidligere generationer kunne ikke
lave samme eksperimenter.
lave samme eksperimenter.
17:58
In another generation down the line,
416
1066580
1825
På et senere tidspunkt
18:00
I think we will have succeeded.
417
1068405
1616
tror jeg, det lykkes for os.
18:02
So to me, it is a privilege, and when I look in the mirror,
418
1070021
3481
Så for mig, er det et privilegium,
og når jeg kigger i spejlet,
og når jeg kigger i spejlet,
18:05
the facts are that I really don't see myself.
419
1073502
2807
ser jeg ikke rigtig mig selv.
18:08
What I see is the generation behind me.
420
1076309
1764
Jeg ser generationen før mig.
18:10
These are some kids from the Huff School, fourth graders.
421
1078073
2026
Børn fra Huff Skolen, fjerde klasse.
18:12
I talked there, what, two weeks ago, something like that.
422
1080099
2945
Jeg holdt et foredrag der
for to ugers tid siden.
for to ugers tid siden.
18:15
I think that if you can instill some interest in science
423
1083044
4610
Kan man indpode
lidt interesse for videnskab
lidt interesse for videnskab
18:19
and how it works, well, that's a payoff
424
1087654
2959
og hvordan det fungerer,
giver det gevinst.
giver det gevinst.
18:22
beyond easy measure. Thank you very much.
425
1090613

udover det sædvanlige. Mange tak.
