End of Universe due to collapse is perhaps closer than we think

Scientists have noted that perhaps our universe is either very close to collapse or it has already started collapsing bringing it closer to its end.

Study Further:

Astronomy initially showed that our universe expanded after its coming into being and they are of the opinion that after a limit of expansion, it will start to collapse but we are not sure whether this collapse will happen and if it will happen, when it will happen.

Now scientists have presented that a radical shift (phase transition) in the forces of the universe will happen when a bubble appears in the Higgs field, the invisible energy field present throughout the universe, imposing a different value to the Higgs particle than the rest of the universe. Expansion of this bubble could result in swallowing of everything in the universe.

“Many theories and calculations predict such a phase transition – but there have been some uncertainties in the previous calculations,” Jens Frederik Colding Krog, Ph.D. student at the Center for Cosmology and Particle Physics Phenomenology at the university and co-author of the study, said in a statement. “Now we have performed more precise calculations, and we see two things: Yes, the universe will probably collapse, and a collapse is even more likely than the old calculations predicted.”

This phase transition would result in making everything heavier to a factor of millions of billions causing them to pull together into a super mass.

“The phase transition will start somewhere in the universe and spread from there,” Krog said. “Maybe the collapse has already started somewhere in the universe and right now it is eating its way into the rest of the universe. Maybe a collapse is starting right now, right here. Or maybe it will start far away from here in a billion years. We do not know.”
