It could come tomorrow or in a billion years. Physicists have long predicted that the universe will collapse here. Only now, however, has this hypothesis been confirmed by calculations. At the same time, they showed that the risk of collapse is more likely than previously thought.
This is claimed by researchers from the University of Southern Denmark, led by Jens Frederik Colding Krog from the Center for Cosmology and Phenomenology of Particle Physics. “We looked at three main equations that predict that a so-called phase transition will occur one day. We found that they interact with each other,” explains the scientist.

A phase transition is a phenomenon where there is a sudden change in the macroscopic properties of a substance. It can also arise in the universe, the space of which is filled with Higgs particles. They, like their earthly colleagues, are looking for the most energetically favorable state. While on our planet this phenomenon manifests itself, for example, in the kitchen by turning water into steam, in space they can create a super hot and heavy cluster.
The end of the universe?
According to theorist Jensem Krog, we cannot tell whether the collapse has already started and is making its way to us right now, or whether it will come in a few million years. However, it is likely that this self-destruction is already underway.

That means only one thing. One day, all the particles around us and in us will become billions of times heavier and become part of a small, hot, heavy sphere. The world as we know it will cease to exist.

However, there is hope that disaster will not occur at all. “The premise for the phase change is that the cosmos is made up of the elementary particles we know today, including the Higgs particle,” says Krog. “If it contains any others, not yet discovered by us, the equations cease to apply.”
The Big Crash Theory
But there is another hypothesis, they predict the end of our universe, and that is “The Big Crunch”. She says that the material that was pushed into the ever-expanding universe by the big bang 13.7 billion years ago will one day begin to attract each other again. This will cause a contraction that will inevitably end in the extinction of all matter in the singularity.

The latest measurements of the speed of the galaxies moving away do not indicate the possibility of a similar development. However, cosmologists themselves admit that they cannot perfectly explain the acceleration of the expansion. So there is a chance that the mechanism can reverse and the universe really starts to shrink.
