How Will the Universe End

We have some knowledge of the universe's beginning, or at least the initial moments, but the future is even less certain. There has been much discussion on the direction of the universe over the years, but no clear solution has emerged. Some people think there is no limit to the universe. It'll just carry on. Contradictory hypotheses contend that the universe won't be quite that lucky.

The Big Crunch, which is the Big Bang's antithesis, is one of the best-known hypotheses. If everyone was thrown away by the Bang, the Crunch would be analogous to the stretching and subsequent contraction of an elastic band. The universe will contract and possibly experience another Big Bang.

According to The Big Freeze, the cosmos is on the verge of dying from heat. Up until all matter and energy are distributed and the immense emptiness of close to absolute zero makes up the entirety of existence, everything will gradually die out to the same uniform temperature across the cosmos.

Another hypothesis is that the previously described dark energy may be able to accumulate more quickly than the cosmos itself. The cosmos will eventually be torn apart by an event known as the Big Rip when we eventually have too much energy and it explodes like a powder keg.
