"Exploring the Fascinating Possibility of a Universe Before Our Own"

In the beginning there was nothing then bang our universe emerged in an explosion of light and energy, or did it?

Let’s shed some light on this.

So how fast is the universe expanding? will the universe and everything in it ever die? and why could our universe have existed before the big bang?

This is what if and here's what would happen if the big bang wasn't the beginning of the universe.

The universe is big…... like astronomically big. Current theories say that it all began 13.7billion years ago and that everything we see came from an infinitely dense point called a singularity but where did that’s singularity come from? There might be more to it than you think and maybe the universe never really had a beginning.

The big bang theory tells us that after the universe emerged from a singularity it started expanding and fast this is known as the cosmic inflation phase and when I say fast, I mean fast…. One moment there was a single point half the size of a DNA molecule a fraction of a second later it expanded to 10.6light years across. This is how the universe we know and love today ended up being relatively stable with hardly any density fluctuations but these small density fluctuations are the reason why we have galaxies and stars. When we start talking about distances this big, we can use the term parsec which is a distance of 3.26 light years, a megaparsec is a million times bigger.

Currently the universe is still expanding its expanding at a rate of 73.5 kilometers per second per megaparsec that means that for every 3.26 million light years an object was away from us it’s moving 73.5 kilometers per second faster but there is a problem if the universe keeps expanding for billions and billions of years at some point it could enlarge too much as in all the energy in it would dissipate and then our universe wouldn’t exist anymore.

But what if its old and there's a new theory in town scientists are calling it the big bounce it’s the combination of the big bang and the big crunch.

The big crunch is when the expansion of the universe goes in reverse and the universe collapses you could say it's the exact opposite of the big bang the big bounce theory says that the universe will eventually start to contract and when it does instead of reaching a singularity it tunnels into another expanding universe. Just imagine a balloon expanding and contracting and each cycle would be our universe starting over again, so you might be asking well how is this different from the big bang.

Well, this theory is different because of what scientists call it the scalar field. The scalar field would make the gravitational field exert negative pressure stopping our universe's contraction then the expansion would begin all over again if this theory is right, it could have serious consequences for our universe first off it would mean that our universe would have no beginning and no end it would be reborn every time it collapsed and if you think about it, that would make our universe infinite. Maybe not in size but in time.

Now if you think you could stick around to see this well that’s probably not going to happen that’s because once the universe contracts it wouldn’t be the same. For instance, matter would be distributed differently so most likely the new version of the universe wouldn't be like ours and it could be so different that the laws of physics wouldn’t be like the laws we know. The universe could emerge in such a way that no stars or planets would form or maybe the universe would form so that complex life forms could flourish. Would that be amazing or what? So if we take a look at the big picture what does this all mean for us? Well not much all the changes would be so far in the future that they won’t affect us whatever they are when it comes to the future of the universe, we know so little that anything could happen so we'll need to keep looking at the stars as the answers are out there somewhere you know what else is out their black holes what would happen if you fell into one of them well that's a story for another what if…
