thank you so much for coming.
terima kasih sudah datang.
literally two hours ago in Vancouver.
di Vancouver dua jam yang lalu.
from Einstein's equation to a black hole?
dari persamaan Einstein ke lubang hitam?
100 tahun lalu,
geometric theory of gravity
teori geometrik tentang gravitasi
how to move around it.
materi bergerak mengitarinya.
into a small enough region
dalam wilayah yang cukup kecil
keeps even light inside.
the reason the Earth moves around the Sun
Bumi mengitari Matahari
seperti yang kita pikirkan,
is pulling the Earth as we think,
the shape of space
sort of fall around the Sun.
ke sekeliling Matahari.
how to move around the Sun.
mengelilingi Matahari.
puncture through space-time,
melalui ruang-waktu,
light orbits the black hole.
mengorbit lubang hitam.
is what's happening here.
sedang terjadi.
of what we always thought,
apa yang selalu kita pikirkan
around the black hole.
sekeliling lubang hitam.
seperti apa lubang hitam itu sebenarnya.
what a black hole really looked like.
like this in supercomputers,
simulasi dengan superkomputer,
lingkaran cahaya,
literally move around the black hole,
mengitari lubang hitam,
that's drawn to the black hole,
yang tertarik ke lubang hitam,
into a very small volume, so it heats up.
supaya panas.
you embarked on this mission
Anda memulai misi ini
one of these things.
menggambarkan hal ini.
nun jauh di sana.
it's 55 million light-years away.
jaraknya 55 juta tahun cahaya.
solar-mass black hole.
lubang hitam.
to really fathom, right?
compressed into a single point.
menjadi satu titik.
of the center of this galaxy.
pusat galaksi ini.
because it's so far away,
karena sangat jauh,
of getting an image of it,
that you need.
butuhkan harus luar biasa.
dalam semesta yang diketahui.
objects in the known universe.
on whole galaxies.
terhadap seluruh galaksi.
as large as the Earth,
that we're looking at
yang berlimpah.
all around the world,
di seluruh dunia,
with atomic clocks,
dengan jam atomik,
from this black hole,
cahaya dari lubang hitam ini,
together to make an image.
untuk membuat gambar.
waktu yang sama,
at the same time,
pemandangan yang jelas.
in a lot of different ways.
dalam berbagai cara.
daripada baik.
to be lucky than good.
kami adalah keduanya.
I like to think.
dari lubang hitam.
through intergalactic space,
ruang intergalaksi,
where water vapor can absorb it,
uap air bisa menyerapnya,
at that wavelength of light,
gelombang cahaya itu,
55 million light-years away.
55 juta tahun cahaya jauhnya.
apa yang harus kita lakukan.
huge amounts of data.
sejumlah besar data.
from just one telescope.
dari hanya satu teleskop.
of our team, Lindy Blackburn,
anggota kami, Lindy Blackburn,
Millimeter Telescope,
mountain in Mexico.
di pegunungan Meksiko.
is about half a petabyte.
sekitar setengah petabyte.
that we might understand,
lifetime selfie budget.
swafoto 5.000 orang.
you couldn't send this over the internet.
mengirimnya lewat internet.
to try and analyze it.
berusaha dan menganalisanya.
coming out of this.
works that we used --
yang kami gunakan --
and smashing it
dan memecahkannya
di tempat yang berbeda-beda.
in different places.
off the surface, which is perfect,
yang berarti sempurna,
at the same time.
di saat yang sama.
later in a supercomputer.
setelahnya di superkomputer.
kind of an Earth-sized lens.
lensa seukuran bumi.
mengirim balik data dengan pesawat.
is to bring the data back by plane.
of a 747 filled with hard discs.
747 dengan hard disc.
atau beberapa bulan lalu,
or a few months ago,
we're really looking at there.
apa yang kami lihat.
is that last orbit of photons.
terakhir dari foton.
geometry laid bare.
secara gamblang.
as I think we'll see soon,
akan kita lihat sebentar lagi,
on these parallel lines
pada kita dalam garis paralel
the square root of 27
akar kuadrat dari 27
of fundamental constants.
fundamental konstan.
when you think about it.
berpikir lubang hitam,
when I thought of black holes,
whirling around in that shape.
sekitar bentuk itu.
more complicated than that.
because it's light being lensed around it.
cahaya dilensakan di sekelilingnya.
from behind it gets lensed,
belakang dilensakan,
around the entire orbit of the black hole.
seluruh orbit lubang hitam.
di sekitar lubang hitam,
swirling around the black hole,
all of these light rays
pancaran cahaya ini
for where you and I are.
begin to come into shape.
lingkaran mulai jelas.
over 100 years ago.
lebih dari 100 tahun lalu.
what we're actually looking at here.
yang kita lihat di sini.
terang dari yang lainnya?
brighter than the rest?
is that the black hole is spinning.
lubang hitam berputar.
moving towards us below
bergerak menuju kita di bawah
has a higher pitch
memiliki nada lebih tinggi
coming towards us than going away from us.
dibanding yang menjauh.
being boosted in our direction.
dikuatkan ke arah kita.
would fit well within that dark region.
masuk ke wilayah gelap itu.
of the event horizon.
tandatangan dari event horizon.
cahaya dari sana,
to us from that place
tempat itu ke arah kita
lubang hitam,
jetting out of it,
keluar dari sana,
directly in our direction.
yang sangat kuat.
it's still powerful,
masih tetap kuat,
of this black hole
lubang hitam ini
to really see all the jet structure,
melihat seluruh struktur pancaran,
that are illuminating the space-time.
menyinari ruang-waktu.
around the black hole.
di sekitar lubang hitam.
whirling around that thing somehow,
ruang angkasa berputar mengitarinya,
to actually go around it?
untuk mengitarinya?
untuk berada dalam pesawat itu.
to be in that spaceship.
if I can get wonky for one moment --
kalau saya boleh ngawur sejenak --
materi bisa bergerak seputar lubang hitam
matter can move around a black hole
between three days and about a month.
tiga hari dan sekitar sebulan.
it's weirdly slow at one level.
satu tingkat.
if you were there.
Anda berada di sana.
"spagetifikasi."
of "spaghettification,"
is much stronger than on your head,
kuat dari yang di kepala Anda,
a spaghetti noodle.
mie spageti.
right through that event horizon.
melalui event horizon.
she ended up in Oz.
dia mendarat di Oz.
terjatuh ke dalam lubang hitam?
if you fall into a black hole?
the central mystery of our age,
di jaman kita,
and the gravitational world come together.
dunia gravitasi berkumpul.
all the forces become unified,
semua gaya menjadi satu,
to compete with all the other forces.
bersaing dengan gaya yang lain.
in the ultimate invisibility cloak.
jubah yang paling tak kasat mata.
yang terjadi di sana.
in our own galaxy.
di galaksi kita.
to our own beautiful galaxy?
galaksi kita yang cantik?
there's another one,
ada satu lagi,
and we've already taken data on it.
sudah mengambil data.
mengerjakannya saat ini.
in the near future, I can't say when.
lagi, saya tidak bisa bilang kapan.
but also a lot smaller,
juga jauh lebih kecil,
to what we saw?
yang kita lihat tadi?
that the black hole in M87,
that it appears a certain size.
nampaknya sebesar itu.
is a thousand times less massive,
seribu kali lebih kecil,
angular size on the sky.
a nod to a remarkable group of people.
untuk sekelompok orang yang mengagumkan.
that this image has had.
dimiliki gambar ini.
above the fold in all of these newspapers,
berada di atas lipatan surat kabar,
have believed you, but it was.
tapi begitulah.
and I hope it's inspiring to everyone.
dan saya harap menginspirasi kita semua.
this is just a small number of the team.
hanyalah jumlah tim yang kecil.
you need a global team.
Anda butuh tim yang global.
of linking telescopes around the world
menghubungkan teleskop di seluruh dunia
some of the issues that divide us.
isu-isu yang memecah kita.
come together to do something like this.
bersatu untuk melakukan hal macam ini.
for our whole team this week.
minggu ini.
lakukan dan datang ke sini.
and for coming here.
