Have you ever wondered how it all began? How
our universe itself was formed? I know I have. People have tried to contemplate
the answer to this mind-bending question since the beginning of time itself.
And after years of wondering, they came up with 7 popular theories in response
to one of humanities greatest mysteries.
** Note: These are in no shape or form all known theories, but merely the widespread or most popular ones
1. White Holes
In order to understand a white hole, you need to know how a black hole works. Black holes are created by a star that died. This star then creates a hole that sucks all light and matter into itself, where it cannot escape. A white hole does the opposite thing; It spits out the matter. So, a white hole lives in the hypothetical region in spacetime, where it can’t take any material in, but only expel it. But white holes haven’t yet been proven to exist, and are a hypothesis created by Albert Einstein’s theory of relativity.2. Mirage of the Black Hole

The slow freeze theory is to some extent a combination of different theories. Based on this idea, the universe was empty before it started. And when the contents of this existence grew in weight while gravity lessened in strength, it created not a big bang, but a slow warming and expansion of the universe. This, in turn created stars and galaxies over time.4. Plasma Creation
5. Pulsating Universe
This theory is also interesting. It talks about the expansion and the retraction of our universe. It says that our universe will always be expanding, until one day, it stops and retracts. The retraction would reach a certain size, and then a humongous explosion comparable to the big bang take place, thus beginning the procedure all over again.6. No Beginning / No End
This theory was a popular belief until the 1960s. It argues that there is the perfect cosmologic principle which declares that our universe is the exact same no matter where you look. There is always creation of matter in our ever-expanding universe. Hence, our universe is and always was the same, everywhere, and all the time, so it has no beginning nor end.
