The sound the universe makes | Janna Levin

Prevoditelj: Damjan Kovač Recezent: Tilen Pigac - EFZG

I want to ask you all to consider for a second

Želim vas zamoliti da razmislite na sekundu

the very simple fact

o jednoj jednostavnoj činjenici

that, by far,

kako je, za sada,

most of what we know about the universe

svo znanje koje imamo o svemiru

comes to us from light.

temeljeno na svjetlu.

We can stand on the Earth and look up at the night sky

Sa Zemlje možemo gledati u noćno nebo

and see stars with our bare eyes.

i vidjeti zvijezde golim očima.

The Sun burns our peripheral vision.

Sunce smeta našem perifernom vidu.

We see light reflected off the Moon.

Vidimo svjetlo reflektirano s Mjeseca.

And in the time since Galileo pointed that rudimentary telescope

Od vremena kada je Galileo usmjerio svoj stari teleskop

at the celestial bodies,

prema nebeskim tijelima,

the known universe has come to us through light,

poznati se svemir uočavao zahvaljujući svjetlu,

across vast eras in cosmic history.

putujući ogromnim razdobljima povijesti kozmosa.

And with all of our modern telescopes,

A sa svim našim modernim teleskopima,

we've been able to collect

uspjeli smo skupiti

this stunning silent movie of the universe --

ovaj zapanjujući nijemi film svemira --

these series of snapshots

ove serije fotografija

that go all the way back to the Big Bang.

koje sežu sve do velikog praska.

And yet, the universe is not a silent movie

Ali ipak, svemir nije nijemi film

because the universe isn't silent.

jer svemir nije tiho mjesto.

I'd like to convince you

Voljela bih vas uvjeriti

that the universe has a soundtrack

kako svemir ima svoju zvučnu pozadinu

and that soundtrack is played on space itself,

a tu zvučnu pozadinu proizvodi sam svemir

because space can wobble like a drum.

jer se prostor može klatiti poput bubnja.

It can ring out a kind of recording

Diljem svemira može odašiljati zvuk

throughout the universe

koji je zapravo snimka

of some of the most dramatic events as they unfold.

nekih najdramatičnijih događaja koji su se ikada dogodili.

Now we'd like to be able to add

Željeli bismo da možemo

to a kind of glorious visual composition

veličanstvenim vizualnim kompozicijama

that we have of the universe --

koje imamo o svemiru, dodati i --

a sonic composition.

zvučne kompozicije.

And while we've never heard the sounds from space,

I pošto nikada nismo čuli zvukove svemira,

we really should, in the next few years,

stvarno bi trebali u sljedećim godinama,

start to turn up the volume on what's going on out there.

obratiti pažnju što se to tamo sa zvukom događa.

So in this ambition

Ambicija za snimkom

to capture songs from the universe,

svemirske pjesme,

we turn our focus

fokusirala nas je na

to black holes and the promise they have,

crne rupe jer su obečavajuće

because black holes can bang on space-time

pošto udaraju prostor-vremenom

like mallets on a drum

poput udaraljke o bubanj

and have a very characteristic song,

stvarajući pritom karakterističan zvuk,

which I'd like to play for you -- some of our predictions

želim vam pustiti zvuk -- koji je pretpostavka

for what that song will be like.

kakav bi mogao biti taj zvuk.

Now black holes are dark against a dark sky.

Crne rupe su crne na crnom nebu.

We can't see them directly.

Ne možemo ih direktno vidjeti.

They're not brought to us with light, at least not directly.

Ne manifestiraju se putem svjetla, barem ne direktno.

We can see them indirectly,

Ali ih možemo vidjeti indirektno

because black holes wreak havoc on their environment.

jer one pustoše prostor oko sebe.

They destroy stars around them.

Uništavaju okolne zvijezde.

They churn up debris in their surroundings.

Ostavljaju krhotine u svom okruženju.

But they won't come to us directly through light.

Ali nam se neće prikazati putem svjetla.

We might one day see a shadow

Jednom možda vidimo sjenu

a black hole can cast on a very bright background,

koju crna rupa stvara na vrlo svijetloj podlozi,

but we haven't yet.

ali to još nije bio slučaj.

And yet black holes may be heard

Ali ipak, možemo ih čuti

even if they're not seen,

iako ih ne vidimo,

and that's because they bang on space-time like a drum.

a to je zbog toga što udaraju prostor-vremenom poput bubnja.

Now we owe the idea that space can ring like a drum

Ideju da svemir udara poput bubnja dugujemo

to Albert Einstein -- to whom we owe so much.

Albertu Einsteinu -- kojem već toliko dugujemo.

Einstein realized that if space were empty,

On je shvatio da bi, kada bi prostor bio prazan,

if the universe were empty,

kada bi svemir bio prazan,

it would be like this picture,

izgledao poput ove fotografije,

except for maybe without the helpful grid drawn on it.

osim možda bez ove nacrtane pomoćne linije.

But if we were freely falling through the space,

Ali kada bi slobodno padali svemirom

even without this helpful grid,

i bez ove nacrtane linije,

we might be able to paint it ourselves,

mi bi je i sami uspjeli nacrtati,

because we would notice that we traveled along straight lines,

jer bismo primijetili da se krećemo ravnom linijom,

undeflected straight paths

ravnim putem

through the universe.

kroz svemir.

Einstein also realized --

Einstein je također shvatio --

and this is the real meat of the matter --

i to je pravo meso matrice --

that if you put energy or mass in the universe,

da ako stavimo energiju ili masu u svemir,

it would curve space,

ona će savinuti prostor,

and a freely falling object

i slobodno padajući objekt

would pass by, let's say, the Sun

prošao bi kraj, recimo, Sunca

and it would be deflected

te bi bio skrenut

along the natural curves in the space.

prirodnom prostornom krivuljom svemira.

It was Einstein's great general theory of relativity.

To je bila Einsteinova velika teorija relativnosti.

Now even light will be bent by those paths.

Na tom putu iskrivljava se i sama svijetlost.

And you can be bent so much

I toliko vas može skrenuti

that you're caught in orbit around the Sun,

da budete uhvaćeni u Sunčevu orbitu

as the Earth is, or the Moon around the Earth.

kao što je to Zemlja, ili Mjesec oko Zemlje.

These are the natural curves in space.

To su prirodne krivulje svemira.

What Einstein did not realize

Ono što Einstein nije shvatio je da

was that, if you took our Sun

ako uzmete naše Sunce

and you crushed it down to six kilometers --

pa ga zgnjećite šest kilometara prema dolje --

so you took a million times the mass of the Earth

tako mu uzmete milijun puta Zemljine mase

and you crushed it to six kilometers across,

pa ga zgnjećite šest kilometara poprijeko,

you would make a black hole,

napravili biste crnu rupu,

an object so dense

toliko gust objekt

that if light veered too close, it would never escape --

da mu ni svijetlost ne bi mogla pobjeći kada bi se dovoljno približila --

a dark shadow against the universe.

crna sjena protiv svemira.

It wasn't Einstein who realized this,

To nije shvatio Einstein

it was Karl Schwarzschild

već Karl Schwarzschild,

who was a German Jew in World War I --

njemački židov u prvom svjetskom ratu --

joined the German army already an accomplished scientist,

priključivši se njemačkoj vojsci već je bio kompletan znanstvenik,

working on the Russian front.

radnik na ruskoj fronti.

I like to imagine Schwarzschild in the war in the trenches

Volim ga zamišljati kako u ratnim rovovima

calculating ballistic trajectories for cannon fire,

izračunava balističke putanje topovske paljbe,

and then, in between,

i tada, u međuvremenu,

calculating Einstein's equations --

izračunavajući Einsteinove jednadžbe --

as you do in the trenches.

kako se to i radi u rovovima.

And he was reading Einstein's recently published

Čitao je nedavno izdanu Einsteinovu

general theory of relativity,

teoriju relativnosti

and he was thrilled by this theory.

i bio je oduševljen.

And he quickly surmised

I ubrzo pretpostavlja

an exact mathematical solution

točno matematičko rješenje

that described something very extraordinary:

koje opisuje nešto fantastično:

curves so strong

toliko snažnu krivulju

that space would rain down into them,

koja iskrivljava sam prostor,

space itself would curve like a waterfall

sam prostor se savija poput vodopada

flowing down the throat of a hole.

gubeći se u ustima rupe.

And even light could not escape this current.

Toj sili ni svjetlo ne može pobjeći.

Light would be dragged down the hole

Svijetlo bi bilo usisano u rupu

as everything else would be,

poput svega ostaloga,

and all that would be left would be a shadow.

i jedino što bi ostalo bila bi sjena.

Now he wrote to Einstein,

Pisao je tada Einsteinu,

and he said, "As you will see,

rekavši, "Kao što ćete vidjeti

the war has been kind to me enough.

rat je bio meni dovoljno dobar.

Despite the heavy gunfire,

Unatoč teškoj paljbi

I've been able to get away from it all

uspio sam svemu tome pobjeći

and walk through the land of your ideas."

i kročiti zemljom Vaših ideja."

And Einstein was very impressed with his exact solution,

Einstein je bio impresioniran njegovim rješenjem,

and I should hope also the dedication of the scientist.

i nadam se njegovom predanošću znanosti.

This is the hardworking scientist under harsh conditions.

To je težak znanstveni rad u teškim uvjetima.

And he took Schwarzschild's idea

Odnio je Schwarzschildovu ideju

to the Prussian Academy of Sciences the next week.

Pruskoj Akademiji Znanosti sljedeći tjedan.

But Einstein always thought black holes were a mathematical oddity.

Ali Einstein je na crne rupe gledao kao na matematičku iskrivljenost.

He did not believe they existed in nature.

Nije vjerovao da postoje u prirodi.

He thought nature would protect us from their formation.

Smatrao je da bi nas priroda zaštitila od njihove formacije.

It was decades

Prošla su desetljeća

before the term "black hole" was coined

prije nego su crne rupe prihvaćene

and people realized

i ljudi shvatili

that black holes are real astrophysical objects --

da su one stvarni astrofizički objekti --

in fact they're the death state

one su zapravo mrtvo stanje

of very massive stars

masivnih zvijezda

that collapse catastrophically

koje se katastrofalno urušavaju

at the end of their lifetime.

na kraju svog života.

Now our Sun will not collapse to a black hole.

Naše se sunce neće urušiti u crnu rupu.

It's actually not massive enough.

Nije dovoljno masivno.

But if we did a little thought experiment --

Međutim, ako napravimo jedan misaoni eksperiment --

as Einstein was very fond of doing --

kako je i Einstein volio raditi --

we could imagine

možemo zamisliti

putting the Sun crushed down to six kilometers,

kako gniječimo Sunce šest kilometara prema dolje,

and putting a tiny little Earth around it in orbit,

i stavljamo malu Zemlju u njegovu orbitu,

maybe 30 kilometers

možda 30 kilometara

outside of the black-hole sun.

izvan sunca - crne rupe.

And it would be self-illuminated,

Bila bi samoosvijetljena,

because now the Sun's gone, we have no other source of light --

pošto je sada sunce nestalo, nemamo drugog izvora svjetla --

so let's make our little Earth self-illuminated.

pa učinimo Zemlju da sama svijetli.

And you would realize you could put the Earth in a happy orbit

Shvatit ćete tako da možete postaviti Zemlju u sretnu orbitu

even 30 km

i 30 kilometara

outside of this crushed black hole.

izvan ove srušene crne rupe.

This crushed black hole

Ova crna rupa

actually would fit inside Manhattan, more or less.

mogla bi se smjestiti, više-manje, unutar Manhattana.

It might spill off into the Hudson a little bit

Mogla bi malo otići u Hudson

before it destroyed the Earth.

prije nego uništi Zemlju.

But basically that's what we're talking about.

Ali u osnovi to je ono o čemu govorimo.

We're talking about an object that you could crush down

Govorimo o objektu koji možete stisnuti

to half the square area of Manhattan.

do veličine pola Manhattana.

So we move this Earth very close --

Tu Zemlju primičemo veoma blizu --

30 kilometers outside --

30 kilometara izvan --

and we notice it's perfectly fine orbiting around the black hole.

i primijetit ćemo da savršeno kruži oko crne rupe.

There's a sort of myth

Postoji mit

that black holes devour everything in the universe,

da crna rupa uništava sve u svemiru,

but you actually have to get very close to fall in.

ali zapravo se morate veoma približiti da bi u nju upali.

But what's very impressive is that, from our vantage point,

A najimpresivnije je to da, s našeg povlaštenog položaja,

we can always see the Earth.

Zemlju uvijek možemo vidjeti.

It cannot hide behind the black hole.

Ne može se sakriti iza crne rupe.

The light from the Earth, some of it falls in,

Nešto Zemljinog svjetla upada u nju,

but some of it gets lensed around and brought back to us.

ali nešto se uvečaje pa nam biva reflektirana.

So you can't hide anything behind a black hole.

Ništa se ne može sakriti iza crne rupe.

If this were Battlestar Galactica

Kad bi ovo bili ratovi zvijezda

and you're fighting the Cylons,

a vi se borite protiv Clyona,

don't hide behind the black hole.

Ne sakrivajte se iza crne rupe.

They can see you.

Vidjet će vas.

Now, our Sun will not collapse to a black hole --

Dakle, naše se Sunce neće urušiti u crnu rupu --

it's not massive enough --

premalena mu je masa --

but there are tens of thousands of black holes in our galaxy.

ali postoje tisuće crnih rupa u našoj galaksiji.

And if one were to eclipse the Milky Way,

I kad bi jedna zamračila Mliječni Put,

this is what it would look like.

ovako bi to izgledalo.

We would see a shadow of that black hole

Vidjeli bi sjenu te rupe

against the hundred billion stars

nasuprot stotina milijardi zvijezda

in the Milky Way Galaxy and its luminous dust lanes.

Mliječnog Puta i njegove svijetlosne staze.

And if we were to fall towards this black hole,

I ako bi padali prema crnoj rupi,

we would see all of that light lensed around it,

vidjeli bi kako se svo to svijetlo oko nje uvečava,

and we could even start to cross into that shadow

čak bi mogli početi prelaziti u tu sjenu

and really not notice that anything dramatic had happened.

i ne bi primijetili da se dogodilo nešto dramatično.

It would be bad if we tried to fire our rockets and get out of there

Bilo bi loše kada bi ispalili rakete ne bi li pobjegli

because we couldn't,

jer ne možemo

anymore than light can escape.

ništa osim svjetla ne može pobjeći.

But even though the black hole is dark from the outside,

I iako je crna rupa izvana tamna,

it's not dark on the inside,

nije takva i iznutra,

because all of the light from the galaxy can fall in behind us.

jer svo svijetlo galaksije pada u nju s nama.

And even though, due to a relativistic effect known as time dilation,

I unatoč relativističkom efektu poznatom kao diletacija vremena,

our clocks would seem to slow down

vrijeme bi nam se na satovima učinilo sporije

relative to galactic time,

u vezi s galaktičkim vremenom,

it would look as though the evolution of the galaxy

izgledalo bi kao da je evolucija galaksije

had been sped up and shot at us,

ubrzana i bačena prema nama,

right before we were crushed to death by the black hole.

netom prije nego što nas je ubila crna rupa.

It would be like a near-death experience

Bilo bi poput iskustva bliskom smrti

where you see the light at the end of the tunnel,

gdje se vidi svjetlo na kraju tunela,

but it's a total death experience.

ali to bi bilo totalno iskustvo smrti.

(Laughter)

(Smijeh)

And there's no way of telling anybody

Tamo nema načina da se nekome kaže

about the light at the end of the tunnel.

o svjetlu na kraju tunela.

Now we've never seen a shadow like this of a black hole,

Nikada nismo vidjeli takvu sjenu crne rupe,

but black holes can be heard,

ali se one mogu čuti,

even if they're not seen.

iako se ne vide.

Imagine now taking an astrophysically realistic situation --

Zamislimo sada jednu astrofizički realnu situaciju --

imagine two black holes that have lived a long life together.

zamislimo dvije crne rupe koje već dugo žive zajedno.

Maybe they started as stars

Možda su počele kao zvijezde

and collapsed to two black holes --

te se urušile u crne rupe --

each one 10 times the mass of the Sun.

svaka od njih s masom 10 puta većom od Sunca.

So now we're going to crush them down to 60 kilometers across.

Sada ćemo ih smanjiti na poprečnih 60 kilometara.

They can be spinning

Mogu se vrtiti

hundreds of times a second.

stotine puta u sekundi.

At the end of their lives,

Na kraju svojih života

they're going around each other very near the speed of light.

kreću se skoro brzinom svijetla jedna oko druge.

So they're crossing thousands of kilometers

Prelaze tisuće kilometara

in a fraction of a second,

u djeliću sekunde,

and as they do so, they not only curve space,

i čineći tako, ne svijaju samo prostor

but they leave behind in their wake

ali za sobom ostavljaju trag

a ringing of space,

prostorne zvonjave,

an actual wave on space-time.

stvarni val prostor-vremena.

Space squeezes and stretches

Prostor se stišće i rasteže

as it emanates out from these black holes

i kako proizlazi iz crnih rupa

banging on the universe.

on udara svemirom.

And they travel out into the cosmos

Putuju diljem svemira

at the speed of light.

brzinom svjetlosti.

This computer simulation

Ovu računalnu simulaciju

is due to a relativity group at NASA Goddard.

dugujemo ekipi iz relativnosti iz NASA-e Goddarda.

It took almost 30 years for anyone in the world to crack this problem.

Bilo je potrebno 30 godina ne bi li netko napokon riješio ovaj problem.

This was one of the groups.

Ovo je jedna od tih grupa.

It shows two black holes in orbit around each other,

Prikazuje dvije crne rupe u međusobnom kruženju jedne oko druge,

again, with these helpfully painted curves.

ponovno s ovim pomoćnim iscrtanim linijama.

And if you can see -- it's kind of faint --

I ako možete vidjeti -- malo je nerazgovjetno --

but if you can see the red waves emanating out,

ali ako možete vidjeti crvene valove koji izlaze izvan,

those are the gravitational waves.

to su gravitacijski valovi.

They're literally the sounds of space ringing,

To su doslovno zvukovi prostora,

and they will travel out from these black holes at the speed of light

i proizlazit će iz ovih crnih rupa brzinom svjetlosti

as they ring down and coalesce

približavajući se prstenu sve dok ne upadnu

to one spinning, quiet black hole

u vrtlog, tihu crnu rupu

at the end of the day.

na kraju svog dana.

If you were standing near enough,

Kada bi stajali dovoljno blizu,

your ear would resonate

uhom bi odjekivalo

with the squeezing and stretching of space.

to stiskanje i rastezanje prostora.

You would literally hear the sound.

Doslovno bi se čuo zvuk.

Now of course, your head would be squeezed and stretched unhelpfully,

Naravno, i vaša glava bi se bespomoćno stiskala i rastezala

so you might have trouble understanding what's going on.

pa možda ne biste shvatili što se događa.

But I'd like to play for you

Ali pustit ću snimku

the sound that we predict.

zvuka kakav smo predvidjeli.

This is from my group --

To je od mog tima --

a slightly less glamorous computer modeling.

malo manje glamurozno računalno modeliranje.

Imagine a lighter black hole

Zamislite lakšu crnu rupu

falling into a very heavy black hole.

kako upada u veoma veliku crnu rupu.

The sound you're hearing

Zvuk koji čujete

is the light black hole banging on space

je udarac manje rupe o prostor

each time it gets close.

svaki put kada se približi.

If it gets far away, it's a little too quiet.

Ako se udalji postaje tiše.

But it comes in like a mallet,

Ali dolazi poput malja

and it literally cracks space,

i stvarno lomi prostor,

wobbling it like a drum.

udarajući poput bubnja.

And we can predict what the sound will be.

A mi možemo predvidjeti taj zvuk.

We know that, as it falls in,

Znamo da, kako sve više upada,

it gets faster and it gets louder.

postaje brže i glasnije.

And eventually,

I eventualno,

we're going to hear the little guy just fall into the bigger guy.

čuti ćemo malu rupu kako upada u veću.

(Thumping)

(Udaranje)

Then it's gone.

Gotovo je.

Now I've never heard it that loud -- it's actually more dramatic.

Nikada to nisam čula tako glasno -- malo je dramatičnije.

At home it sounds kind of anticlimactic.

Kod kuće zvuči manje dramatično.

It's sort of like ding, ding, ding.

Poput ding, ding, ding.

This is another sound from my group.

Ovo je sljedeći zvuk mog tima.

No, I'm not showing you any images,

Ne, neću vam pokazati fotografije,

because black holes don't leave behind

jer crne rupe ne ostavljaju za sobom

helpful trails of ink,

pomoćni trag,

and space is not painted,

i prostor nije obojan,

showing you the curves.

prikazujući krivulje.

But if you were to float by in space on a space holiday

Ali kada biste putovali svemirom tijekom svemirskih praznika,

and you heard this,

čuvši ovo

you want to get moving.

željeli biste otići.

(Laughter)

(Smijeh)

Want to get away from the sound.

Željeli biste otići što dalje od tog zvuka.

Both black holes are moving.

Obje se crne rupe pomiču.

Both black holes are getting closer together.

Obje se međusobno približavaju.

In this case, they're both wobbling quite a lot.

U ovom slučaju obje snažno udaraju.

And then they're going to merge.

I obje će se spojiti.

(Thumping)

(Udaranje)

Now it's gone.

Gotovo je.

Now that chirp is very characteristic of black holes merging --

Taj cvrkut je karakterističan prilikom spajanja crnih rupa --

that it chirps up at the end.

to se čuje na kraju.

Now that's our prediction

To što smo vidjeli

for what we'll see.

naše je predviđanje.

Luckily we're at this safe distance in Long Beach, California.

Srećom smo mi na sigurnoj udaljenosti u Long Beachu, Kaliforniji.

And surely, somewhere in the universe

Ali sigurno su se negdje u svemiru

two black holes have merged.

spojile dvije crne rupe.

And surely, the space around us

I sasvim sigurno, prostor oko nas

is ringing

zvoni

after traveling maybe a million light years, or a million years,

nakon putovanja milijunima svjetlosnih godina, ili milijunima godina

at the speed of light to get to us.

brzinom svjetlosti ne bi li došao do nas.

But the sound is too quiet for any of us to ever hear.

Ali taj je zvuk pretih za sve nas.

There are very industrious experiments being built on Earth --

Mnogo je eksperimenata napravljeno na Zemlji --

one called LIGO --

jedan se zove LIGO --

which will detect deviations

koji će detektirati devijacije

in the squeezing and stretching of space

stiskanja i rastezanja prostora

at less than the fraction of a nucleus of an atom

manjeg od djelića atoma

over four kilometers.

na četiri kilometra.

It's a remarkably ambitious experiment,

To je nevjerojatno ambiciozan eksperiment,

and it's going to be at advanced sensitivity

i vršit će se naprednom osjetljivošću

within the next few years -- to pick this up.

unutar sljedeće četiri godine -- ne bi li se to zabilježilo.

There's also a mission proposed for space,

Postoji i misija koja se predlaže za prostor,

which hopefully will launch in the next ten years,

koja će biti realizirana, nadam se, u sljedećih 10 godina,

called LISA.

zove se LISA.

And LISA will be able to see super-massive black holes --

LISA će moći vidjeti super-velike crne rupe --

black holes millions or billions of times

crne rupe koje su milijune ili milijarde puta

the mass of the Sun.

masivnije od Sunca.

In this Hubble image, we see two galaxies.

Na ovoj Hubbleovoj fotografiji vidimo dvije galaksije.

They look like they're frozen in some embrace.

Izgledaju kao zamrzute u zagrljaju.

And each one probably harbors

I svaka je vjerojatno pristanište

a super-massive black hole at its core.

super-masivnim crnim rupama u svojoj jezgri.

But they're not frozen;

Ali nisu zamrznute;

they're actually merging.

zapravo se spajaju.

These two black holes are colliding,

Ove dvije rupe se sudaraju,

and they will merge over a billion-year time scale.

i spojit će se u periodu od preko milijarde godina na vremenskoj skali.

It's beyond our human perception

Izvan je našeg poimanja

to pick up a song of that duration.

snimiti zvug takvog trajanja.

But LISA could see the final stages

Ali LISA može vidjeti završni stadij

of two super-massive black holes

dvije super masivne crne rupe

earlier in the universe's history,

iz svemirske povijesti,

the last 15 minutes before they fall together.

zadnjih 15 minuta prije nego su se spojile.

And it's not just black holes,

I to nisu samo crne rupe,

but it's also any big disturbance in the universe --

to je i veliki nemir u svemiru --

and the biggest of them all is the Big Bang.

a najveći od njih je veliki prasak.

When that expression was coined, it was derisive --

Kada se prihvatila ta ekspresija, bila je izrugivana --

like, "Oh, who would believe in a Big Bang?"

"Ma tko bi vjerovao u veliki prasak?"

But now it actually might be more technically accurate

Ali sada je to više tehnički precizno

because it might bang.

jer bi moglo prasnuti.

It might make a sound.

Moglo bi stvoriti zvuk.

This animation from my friends at Proton Studios

Animacija prijatelja u Proton Studiosu

shows looking at the Big Bang from the outside.

prikazuje pogled na veliki prasak izvan njega.

We don't ever want to do that actually. We want to be inside the universe

Mi to zapravo nikada ne želimo. Ne želimo biti izvan svemira

because there's no such thing as standing outside the universe.

jer nema izvan svemira.

So imagine you're inside the Big Bang.

Pa zamislite da ste unutar velikog praska.

It's everywhere, it's all around you,

On je posvuda, svuda oko vas,

and the space is wobbling chaotically.

a prostor kaotično bubnja.

Fourteen billion years pass

14 milijardi godina kasnije

and this song is still ringing all around us.

ta pjesma još uvijek odjekuje oko nas.

Galaxies form,

Oblici galaksija

and generations of stars form in those galaxies,

i generacije zvjezdanih oblika u tim galaksijama,

and around one star,

i oko jedne zvijezde,

at least one star,

barem jedne zvijezde,

is a habitable planet.

nalazi se nastanjiv planet.

And here we are frantically building these experiments,

I tako mi grčevito gradimo te eksperimente,

doing these calculations, writing these computer codes.

Izračunavajući i pišući računalne kodove.

Imagine a billion years ago,

Zamislite milijardu godina nazad,

two black holes collided.

kada su se dvije crne rupe spojile.

That song has been ringing through space

Ta pjesma zvoni kroz prostor

for all that time.

svo to vrijeme.

We weren't even here.

Nismo još ni bili ovdje.

It gets closer and closer --

Sve je bliže --

40,000 years ago, we're still doing cave paintings.

prije 40.000 godina još smo crtali po pećini.

It's like hurry, build your instruments.

Kao brzo, izgradite svoje instrumente.

It's getting closer and closer, and in 20 ...

Sve je bliže, i 20 ...

whatever year it will be

koja će već godina biti

when our detectors are finally at advanced sensitivity --

kada naši detektori napokon budu super osjetljivi --

we'll build them, we'll turn on the machines

napravili smo ih, pa upalite strojeve

and, bang, we'll catch it -- the first song from space.

i bum, ulovit ćemo ih -- prve zvukove svemira.

If it was the Big Bang we were going to pick up,

Ako će ti zvukovi biti oni velikog praska,

it would sound like this.

zvučat će poput ovoga.

(Static) It's a terrible sound.

(Statičnost) Strašan zvuk.

It's literally the definition of noise.

To je doslovno definicija buke.

It's white noise; it's such a chaotic ringing.

Bijeli šum; takva kaotična zvonjava.

But it's around us everywhere, presumably,

Ali ono je svugdje oko nas, naravno,

if it hasn't been wiped out

ako nije bilo izbrisano

by some other process in the universe.

nekim drugim procesom u svemiru.

And if we pick it up, it will be music to our ears

I ako snimimo, bit će to muzika za naše uši

because it will be the quiet echo

zbog tihe jeke

of that moment of our creation,

tog trenutka stvaranja

of our observable universe.

našeg postojećeg svemira.

So within the next few years,

Tijekom nekoliko sljedećih godina

we'll be able to turn up the soundtrack a little bit,

moći ćemo malo upaliti glazbu,

render the universe in audio.

pustiti svemir preko zvučnika.

But if we detect those earliest moments,

Ali ako pronađemo te rane trenutke

it'll bring us that much closer

odvest će nas mnogo bliže

to an understanding of the Big Bang,

razumijevanju velikog praska,

which brings us that much closer

što nas dovodi mnogo bliže

to asking some of the hardest, most elusive, questions.

postavljanju najtežih pitanja.

If we run the movie of our universe backwards,

Ako pustimo film svemira unatrag

we know that there was a Big Bang in our past,

znamo da je tamo bio veliki prasak,

and we might even hear the cacophonous sound of it,

i možda čujemo i njegov kakofonički zvuk,

but was our Big Bang the only Big Bang?

ali, da li je veliki prasak jedini veliki prasak?

I mean we have to ask, has it happened before?

Mislim, moramo se upitati, je li se dogodio i prije?

Will it happen again?

Dogodit će se opet?

I mean, in the spirit of rising to TED's challenge

Mislim, u duhu TED-ovog izazova

to reignite wonder,

da se čuda ponovno ožive

we can ask questions, at least for this last minute,

možemo postavljati pitanje, barem u ovih zadnjih minutu vremena

that honestly might evade us forever.

koja će nas možda zauvijek izbjegavati

But we have to ask:

Ali moramo upitati:

Is it possible that our universe

Da li je moguće da je naš svemir

is just a plume off of some greater history?

samo pero na perjanici veće povijesti?

Or, is it possible that we're just a branch off of a multiverse --

Ili je moguće da smo samo grana multisvemira --

each branch with its own Big Bang in its past --

svaka grana sa svojim velikim praskom u prošlosti --

maybe some of them with black holes playing drums,

možda neki od njih bubnjaju crnim rupama,

maybe some without --

neki možda ne --

maybe some with sentient life, and maybe some without --

neki možda osjetljivim životom, neki možda bez --

not in our past, not in our future,

ne u našoj prošlosti, ne u budućnosti,

but somehow fundamentally connected to us?

ali ipak nekako istinski spojeno s nama?

So we have to wonder, if there is a multiverse,

Moramo se zapitati, ako postoji multisvemir,

in some other patch of that multiverse,

u nekom sloju tog multisvemira

are there creatures?

postoje li neka bića?

Here's my multiverse creatures.

Ovdje su moja bića iz multisvemira.

Are there other creatures in the multiverse,

Ima li i ostalih bića,

wondering about us

koja se pitaju i o nama

and wondering about their own origins?

tražeći svoje vlastito podrijetlo?

And if they are,

I ako ih ima,

I can imagine them as we are,

mogu ih zamisliti poput nas,

calculating, writing computer code,

računaju, pišu računalne kodove,

building instruments,

grede instrumente,

trying to detect that faintest sound

pokušavaju pronaći te tamne zvukove

of their origins

svojih korijena

and wondering who else is out there.

pitajući se ima li još nekoga tamo.

Thank you. Thank you.

Hvala. Hvala.

(Applause)
