The Big Bounce Theory

Every one of us knows that our universe was born after the Big Bang, but do you think that the fate of universe was a little bit different from our perception?

Maybe and maybe not.

So, my friends, let us try to explore the birth of our universe, which was probably the end of another universe.

Here, we will look at a completely different theory. THE BIG BOUNCE THEORY.

WHAT'S THIS NEW BIG B? 

This theory is based on Quantum mechanics. It states that the big bang, which was the beginning of our universe, was the end for another universe which existed before ours came into being.

You may ask that how is it possible! Another universe! 

Yes, it is possible, but everyone needs an explanation, so let's understand it.

The big bounce theory simply says that our universe goes through expansion and contraction and so on.

Hold on! we will see the procedure later in this article.

Well, big bang says that the universe started from a singularity(a point in space with infinite density, zero volume and which is extremely hot), but big bounce says that singularities do not exist! You may like to read this article to know more about, why singularities cannot exist.

BIG BOUNCE VS BIG BANG.

BIG BANG

BIG BOUNCE

Big bang says that our universe was born from a singularity. All the mass was compresses to a single point with zero volume. 

That point expanded decreasing the temperature and creating our universe.

But quantum mechanics says that when the universe was so small, it must have been ruled by micro particles, but quantum physics will not allow the particles to compress to an infinitely dense point(singularity).

But the particles are allowed to be compressed and have finite density and this place will be very hot.

This also means that there was a universe before ours which compressed into such a dense point and later created our universe.

THE CONTRACTION.

We understood the big bounce theory, but why will our universe or the one before ours contract? 

For expansion the universe requires a special energy and when this energy will be exhausted, a new force will dominate which will cause the contraction and when it will have enough energy, it will start to expand again. 

In these many ways can the universe end. 

The energy we are talking about is heat which will be produced due to high density.

This theory is also very interesting as the big bang, but it raises many new questions.

If big bang was not the beginning then, how did this all start?

There are many other questions yet to be answered. 

The unseen is yet to be answered.
