Physicists: The universe is in danger of evaporating


Astrophysicists have discovered a mysterious radiation in which all massive matter eventually evaporates. Nothing lasts forever, and Hawking radiation, named after the late British physicist Stephen Hawking, is characteristic not only of black holes, but of other massive objects in the universe. This means that, like all black holes, they gradually evaporate. Over time, it will completely evaporate, that is, it will disappear. Dutch astrophysicists from the University of Nijmegen predict such an outcome for the universe.

Radiation from black holes is believed to originate near the so-called “event horizon,” a certain region beyond which the black hole’s gravitational pull cannot escape. It draws you in and won’t keep you coming back.

In a study published in the journal Physical Review Letters, the Dutch demonstrated that radiation similar to Hawking radiation can occur beyond the event horizon, i.e. in the curved regions of the fabric of spacetime. For example, according to the “Russia Today” website, next to large bodies such as stars and planets.

“Some kind of Hawking radiation eventually evaporates everything around like black holes,” says one of the study’s authors. While scientists at the California Institute of Technology believe the universe may be evaporating faster than the Dutch think, its rapid expansion worries them.

And they say: “The repulsive forces resulting from dark matter or dark energy will cause the expansion of the universe, leading to the Big Bang, which will explode after 22 billion years.”

According to a hypothesis put forward by scientists, our Milky Way would have disintegrated 60 million years before the Big Bang. And 3 months before all the results are over, the planets of the solar system will be dispersed. Half an hour before that, our earth will turn to dust. At the last moment, the nuclei will dissolve, and with them everything in the universe.

And then, does something happen after the evaporation or the big bang? – Probably nothing else. But it is inconceivable that material that vaporized or decayed without a trace as we know it would suddenly reassemble into a very dense point and explode in a new big bang, as it did 14 billion years ago. , after which the resulting universe evaporated and began to expand.
