Sometimes when I'm on a long plane flight,

Ponekad, kada sam na dugačkom letu,

I gaze out at all those mountains and deserts

posmatram sve te planine i pustinje

and try to get my head around how vast our Earth is.

i pokušavam da shvatim koliko je zapravo velika naša Zemlja.

And then I remember that there's an object we see every day

Onda se setim da je tu predmet koji vidimo svakoga dana

that would literally fit one million Earths inside it.

u koji bi, bukvalno, stalo milion Zemalja.

The sun seems impossibly big,

Sunce deluje nemoguće veliko,

but in the great scheme of things, it's a pinprick,

ali u celom funkcionisanju stvari, to je samo delić,

one of about 400 billion stars in the Milky Way galaxy,

jedna od oko 400 milijardi zvezda u galaksiji Mlečni puti,

which you can see on a clear night

koju možete videti po vedroj noći kao bledu, belu izmaglicu, rastegljenu preko neba.

as a pale, white mist stretched across the sky.

And it gets worse.

Stvar se pogoršava.

There are maybe 100 billion galaxies detectable by our telescopes,

Postoji možda 100 milijardi galaksija vidljivih našim teleskopom,

so if each star was the size of a single grain of sand,

tako da kada bi svaka zvezda bila veličine zrna peska,

just the Milky Way has enough stars to fill

samo Mlečni put bi imao dovoljno zvezda da ispuni

a 30 foot by 30 foot stretch of beach three feet deep with sand.

plažu širine 9 sa 9 metara i 90 cm dubine u pesku.

And the entire Earth doesn't have enough beaches

Cela Zemlja nema dovoljno plaža

to represent the stars in the overall universe.

da prikaže zvezde u celom univerzumu.

Such a beach would continue for literally hundreds of millions of miles.

Takva plaža bi se bukvalno protezala stotinama miliona kilometara.

Holy Stephen Hawking, that is a lot of stars.

Stivena Hokinga mu, to je mnogo zvezda.

But he and other physicists now believe in

Ali on i drugi fizičari sada veruju

a reality that is unimaginably bigger still.

u realnost koja je nezamislivo još veća.

I mean, first of all, the 100 billion galaxies within range of our telescopes

Mislim, najpre, 100 milijardi galaksija u okvirima našeg teleskopa

are probably a minuscule fraction of the total.

su verovatno minijaturan razlomak sveukupnog.

Space itself is expanding

Sam svemir se širi

at an accelerating pace. The vast majority of the galaxies

ubrzanim korakom. Velika većina galaksija

are separating from us so fast

se od nas toliko brzo udaljava

that light from them may never reach us.

da svetlo od njih možda nikada ne dođe do nas.

Still, our physical reality here on Earth

Ali ipak, naša fizička realnost ovde na Zemlji

is intimately connected to those distant, invisible galaxies.

je blisko povezana sa onim udaljenim, nevidljivim galaksijama.

We can think of them as part of our universe.

Možemo da mislimo o njima kao o delu našeg univerzuma.

They make up a single, giant edifice,

Oni sačinjavaju jedno, ogromno zdanje,

obeying the same physical laws and all made from the same types of atoms, electrons,

pokoravajući se istim fizičkim zakonima i svi su sačinjeni iz istih vrsta atoma, elektrona,

protons, quarks, neutrinos that make up you and me.

protona, kvarkova, neutrona koji sačinjavaju tebe i mene.

However, recent theories in physics,

Međutim, skorašnje teorije u fizici,

including one called string theory,

kao i teorija struna,

are now telling us there could be countless other universes,

govore nam da bi moglo da postoji još nebrojivo mnogo drugih univerzuma,

built on different types of particles,

koji su sagrađeni od drugačijih vrsta čestica,

with different properties, obeying different laws.

sa drugačijim svojstvima i pokoravaju se drugačijim zakonima.

Most of these universes could never support life,

Većina ovih univerzuma nikada ne bi mogla da podrži život

and might flash in and out of existence in a nanosecond,

i mogli bi da se pojave ili nestanu za nanosekundu,

but nonetheless, combined

ali ipak, kombinovani

they make up a vast multiverse of possible universes.

čine veliku različitost mogućih univerzuma

in up to 11 dimensions, featuring wonders beyond our wildest imagination.

u 11 dimenzija, uz čuda koja su izvan naše najluđe mašte.

And the leading version of string theory

Vodeća verzija teorije struna

predicts a multiverse made of up to 10 to the 500 universes.

predviđa multiverzum koji sačinjava od 10 na 500 univerzuma.

That's a one followed by 500 zeroes,

To je jedan praćen sa 500 nula,

a number so vast that if every atom in our observable universe

brojem koji je toliko veliki da kada bi svaki atom u našem vidljivom univerzumu

had its own universe

imao svoj sopstevni univerzum

and all of the atoms in all of those universes

i kada bi svi atomi u svim univerzumima

each had their own universe,

svaki imali svoj univerzum,

and you repeated that for two more cycles,

i kada biste to ponovili sa još dva kruga,

you'd still be at a tiny fraction of the total --

i dalje biste bili kod malog razlomka celine ---

namely, one trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillionth.

što znači jedan bilion biliona biliona biliona biliona biliona biliona biliona biliona biliona biliona biliona biliona biliona biliona.

But even that number is minuscule compared to

Čak je i taj broj minijaturan kada ga uporedimo sa

another number: infinity.

drugim brojem: beskonačnošću.

Some physicists think the space-time continuum

Neki fizičari misle da je kontinuum prostor-vreme

is literally infinite, and that it contains an infinite number

bukvalno beskrajan i da se sastoji iz beskonačnog broja,

of so-called pocket universes with varying properties.

takozvanih džepnih univerzuma sa osobinama koje se menjaju.

How's your brain doing?

Kako je vaš mozak?

But quantum theory adds a whole new wrinkle.

Kvantna teorija dodaje potpuno novu boru.

I mean, the theory's been proven true beyond all doubt,

Mislim, teorija je dokazana istinitom izvan svake sumnje,

but interpreting it is baffling.

ali je njeno tumačenje je zbunjujuće.

And some physicists think you can only un-baffle it

Neki fizičari misle da je jedino možete pojasniti

if you imagine that huge numbers of parallel universes

ako zamislite da se taj veliki broj paralelnih univerzuma

are being spawned every moment,

razmnožava svakog trenutka

and many of these universes would actually be very like the world we're in,

i mnogi od ovih univerzuma bi zapravo bili upravo kao svet u kome živimo,

would include multiple copies of you.

sastojali bi se iz više kopija vas.

In one such universe, you'd graduate with honors and marry the person of your dreams.

U jednom takvom univerzumu, diplomirali biste sa najboljim ocenama i udali biste se za osobu iz snova.

In another, not so much.

U nekom drugom, ne bi baš bilo tako.

There are still some scientists who would say, hogwash.

I dalje postoje naučnici koji bi rekli da su to budalaštine.

The only meaningful answer to the question of how many universes there are is one,

Jedini značajan odgovor na pitanje koliko ima univerzuma je ovaj:

only one universe.

postoji samo jedan univerzum.

And a few philosophers and mystics

Nekoliko filozofa i mističara

might argue that even our own universe is an illusion.

bi mogli da kažu da je čak i naš univerzum iluzija.

So, as you can see,

Kao što možete da vidite,

right now there is no agreement on this question,

trenutno ne postoji slaganje u vezi sa ovim pitanjem,

not even close.

ni izbliza.

All we know is, the answer is somewhere between zero and infinity.

Sve što znamo je da je odgovor negde između nule i beskonačnosti.

Well, I guess we know one other thing:

Pretpostavljam da znamo još jednu stvar:

This is a pretty cool time to be studying physics.

ovo je odličan trenutak za učenje fizike.

We just might be undergoing

Moguće je da upravo proživljavamo

the biggest paradigm shift in knowledge that humanity has ever seen.

najveću promenu paradigme u znanju koju je čovečanstvo ikada videlo.
