Big Bang, the explosion that gave birth to our Universe, took place about 13.8 billion years ago. But, as we already know it, everything comes to an end, and that would also happen to the Universe. According to scientific predictions, the Universe will implode, eventually, taking everything with it.
But, we don’t have to worry about that since the Universe is still in its expansion phase, so the moment when it will implode is still, probably, billions of years away. According to scientists, the Big Freeze, the Big Rip, and the Big Crunch are the three possibilities regarding the end of the world. Professor Venus Keus explained each of the three possible events by comparing the forces between galaxies with rubber.
“The Big Freeze scenario is what happens if the force pulling the objects apart is just strong enough to stretch the rubber band until it loses its elasticity. The universe would become darker and colder, approaching a frozen state also known as the Big Chill, or the Heat Death of the Universe,” Professor Keus said.
The Universe will eventually implode, but it might explode back with a new Big Bang
The second end of the Universe, the so-called Big Rip, is when the Universe expansion continues to accelerate until the forces between the galaxies and other space objects will diminish, “tearing apart galaxies and solar systems,” as Keus said. Also, electromagnetic and nuclear forces that hold atoms together will disappear.
But, the most intriguing scenario is the so-called Big Crunch, which implies the fact that the Universe will implode. And this seems the most probable one, suggesting that the Universe is infinite, exploding in Big Bang-like expansions and imploding forever. “Galaxies would start rushing towards each other, and as they clumped together, their gravitational pull would get even stronger. Stars too would hurtle together and collide. Temperatures would rise as space would get tighter and tighter,” Venus Keus explained.
“The result would be an incredibly dense, hot, compact universe — a lot like the state that preceded the Big Bang. This is the Big Crunch (…) There’s no way to tell how many bounces could’ve already happened— or how many might happen in the future. Each bounce would wipe away any record of the universe’s previous history,” Prof. Venus Keus concluded, cited by Daily Star.
