Eternety is a long time, especially towards the end. – Woodie Allen

Since ancient times people have been curious to know how it could be the end of humanity.
Although we assume that this happened several times, some are still wondering how could mankind find its final days?

We went ahead and we wondered how that might end up even the universe itself.
Below we share some of the most plausible theories that scientists claim could be real:

The Big Crunch

It is similar to the Big Bang Theory, but in reverse.

The Big Crunch Theory claims that everything we know in the universe will come back to the same point from which it started.

Having the reversed effect of the big bang, it means that our universe is not expanding, but will it eventually shrink.

The Big Freeze

This theory is not about expansion or restriction universe. Instead, we talk about the future stars that we see. They are running out of fuel and will fade out.

Not having any source of light and heat, the universe will enter in a total freeze with temperatures that are unimaginably low.

Called “The death of the heat ‘, the fulfillment of the theory would bring total darkness in the universe.

The Big Rip

This theory is more complex than the previous ones. It says that due to the continuous expansion, all the elements that make up the universe, from atoms to galaxies, will be broken.

All the material in the universe will explode.

Observations of the stars and galaxies indicate that the universe is expanding. In the end, eventually the stars will die out, everything will drift apart, and the universe will dissapear. It could collapse back on itself, like a balloon. The rate of this expansion may eventually tear the Universe apart, forcing it to end in a Big Rip.
