5 Scenarios for the Death of the Universe

(ORDO NEWS) — Mainstream science holds the theory that around 13.8 billion years ago, space and time formed from an incredibly dense point of singularity, and this event became known as the Big Bang.

Since then, the universe has been expanding at an accelerating rate. How could this end?

1- Big freeze

According to the best models of the evolution of the Universe, the most likely scenario is what is called the Big Freeze.

If the expansion does not stop for many years, then all objects will be too far apart. This process will take trillions of years.

At one of the final stages, only black holes will remain in space, but they are not eternal either.

Sooner or later, even particles will stop interacting with each other, and matter and light will become a thing of the past.

2- Big gap

A similar scenario leads to a much more dramatic death, and much sooner. In this model, dark energy accelerates the expansion of the universe exponentially, eventually tearing apart matter itself.

3- Big squeeze

In this scenario, the expansion of the universe eventually changes to contraction, and the universe collapses, and eventually collapses back into a singularity.

This is possible if the density of matter in space is high enough. Then its gravity can overcome the expansion.

Different scientists give different estimates of when this contraction phase may begin – in millions or billions of years.

4- Big bounce

There is another version of the above hypothesis. Moments before the universe collapses into an infinitely dense singularity, he suggests, it will change course again and resume its period of expansion.

5- Big “slurp”

The last doomsday scenario on this list is perhaps the most troubling because it could affect us. Perhaps we will see the collapse of the false vacuum.

As a result of this, huge energy will be released, due to which a large number of particles will be formed, which will lead to the reheating of the Universe. And all this, of course, will happen without warning.
