how was our universe born and if this seems hard to answer then how about this what was before our universe while scientists are looking for the answer to the most difficult question in history let's find out what they've come up with so far in the 20th century we've shed the light on this mystery all thanks to this man Edwin Hubble one day on Mount Wilson in Southern California he aimed his telescope at the sky and found out that these random clouds of gas flying everywhere are actually other galaxies and there are a lot of them
and also he learned something else something that changed the world forever they're moving so what you may ask well it meant one very important thing the universe is expanding and if it's expanding then it probably had a beginning somewhere right now all we have to do is run time backwards and see where the beginning was it took the scientists many more years to come up with a full-fledged Theory The Big Bang Theory and here it is nothing has ever been anywhere because neither when nor where existed do you get it but actually no there was
one thing it was the so-called CA mic Singularity a state of our universe in which it was incredibly small dense and very hot imagine if our universe was compressed into a small ball the pressure and temperature inside would be enormous at some point it became impossible to withstand them and here comes the Big Bang it was an outburst of energy and matter that created everything we see now time and space basic physical forces it also scattered quirks everywhere these corks tiny particles that make up our world were all boiling in an incredibly hot Cosmic broth
when it cooled down gravity began to attract them to each other they gathered into atoms then molecules and then into the first objects into the world stars and all this happened just some 12 to 14 billion years ago all right now we know how our universe was created but what was before that Alan Harvey Guth an American theoretical physicist and cosmologist has devoted his whole life to solving this mystery after learning about the Big Bang Theory Guth found some flaws in it for example the distribution of matter was very even although it shouldn't have been
let's hang a balloon filled with paint to the ceiling and lay a white canvas on the floor if we drop the balloon down it will burst and we'll see absolute Chaos on the canvas a bunch of spots scattered everywhere randomly neither is like the other but that's not really what the universe looked like instead of throwing a colored ball from the ceiling let's draw a small red dot on the canvas now let's expand it a little more and more and capture this all on frame by frame shooting we'll see a circle gradually growing in all
directions that's the reality the early Universe was very even and proportional that was guth's Discovery the theory of inflation here's what it says even before the Big Bang there was some kind of force that could give the bang a strong acceleration something that was able to distribute everything in space instantly and evenly guth's theory was a success and now most scientists rely on it for most of them this idea of the birth of the universe is quite enough for most but not for all Martin bojowald is a German professor of physics and in his opinion
the universe was born quite differently remember when we talked about Cosmic Singularity the state of the universe in which it was small infinitely dense and super hot according according to Martin's Theory The Singularity couldn't just appear out of nowhere this is nonsense but then where did it come from let's look at a pendulum on an old clock the pendulum rotates back and forth its movement is smooth continuous and non-stop this is how we usually see time it flows and never stops but Quantum time ho ho Quantum time doesn't work that way it's more like the
second hand of a clock it consists of small segments and makes short pauses and just like with the second hand of a clock the beginning of one segment of time is always the end of another see what I'm getting at let's go back to balloons again according to the Big Bang Theory Once Upon a Time our universe began to expand inflate like a balloon but sooner or later it will blow away back the universe will start shrinking and return to the state of Cosmic Singularity and then guess what the big bang too nothing appears out
of nowhere and disappears into nowhere according to boj wald's Theory the beginning of each universe is the end of the previous one our universe is not at all the first and not the last millions of similar universes existed before us and will exist after us this Theory although it sounds very logical is far far from complete unfortunately we don't have enough knowledge to find all the evidence for it so for now all this is just a hypothesis but some people come up with even stranger ideas scientists promote such unusual theories that no one could even
think of Neil Turk a South African physicist and his colleague Paul steinhardt an American theoretical physicist look for answers far beyond our universe they say that yes our universe isn't the first one there have been and will be an infinite number of them and not only will there be endless Big Bangs our universe is just one of an infinite number of others and all of us are stuck in a cycle of endless rebirths of parallel worlds this sounds incredible and frightening at the same time but how does it work according to this Theory our universe
is located inside a so-called brain as in membrane in other words we're stuck in some kind of elastic surface that's capable of Contracting stretching oscillating and so on like pieces of fabric on a rope these parallel universes are located near each other each one has a neighbor we're not the exception another universe may be an inch from ours but we can't see it that's because there's a tiny space between us and this tiny space contains the fourth dimension how do these universes originate through brain Collision these brains are getting closer to each other very very
slowly until one day they finally Collide their Collision creates two big bangs and two parallel universes then they're moving away from each other the created worlds continue to live we're currently at this stage but when they disappear the brains Collide again and this will lead to the birth of a new universe remember the inflation Theory there was a mysterious energy that pushed and accelerated the Big Bang well if we did Collide With Another Universe that would explain everything of course everything described here is a great simplification when you hear that our world is some piece
of fabric on a rob it sounds like complete nonsense but this idea is based on string theory and M Theory two giants of quantum mechanics if they turn note to be true they could explain almost everything in our universe creating a theory is an incredibly huge process Turk and steinhardt made a huge amount of calculations and swept away many many non-working theories also to work this out they have to overcome the limits of the human mind and think in 11 Dimensions at once unfortunately this crazy and elegant idea was laughed at turro and steinhardt say
that scientists are regular people just like everyone else they're also afraid of change and the unknown and it's really scary to question everything we once believed in many years ago people didn't believe that the Earth was round then they were outraged by The Big Bang Theory we can't make discoveries without struggle and fear that's why Turk and steinhardt don't plan to give up so easily after all the evidence that we have now only says that each of the three theories is equally possible so which answer is correct we may never know at least not at
this stage of human development unfortunately as long as we have no evidence we can only theorize but maybe one day we'll find something that will open our eyes once and for all maybe one day we'll solve the mystery of how our universe came to be that's it for today so hey if you pacified your curiosity then give the video a like and share it with your friends or if you want more just click on these videos and stay on the bright side
