Index – Tech-Science – Could the evaporation of celestial bodies mean the end of the world?

Stephen Hawking published his theory in 1974, according to which black holes evaporate over time as they gradually lose energy in the form of heat. Based on the theory, the larger the black hole, the slower it evaporates. However, the phenomenon called Hawking radiation has not yet been verified by observation. Hawking’s theory that combined relativity and quantum mechanics also led to a paradox, because as a result of evaporation, information is lost in a way that contradicts the basic principles of quantum mechanics.

To the faculty of Radboud University in the Netherlands Physical review lettersHowever, its theoretical explanation, which was recently published in

According to quantum mechanics, outer space is not space at all, but rather a space full of undulating fields, in which virtual particles and their antiparticle pairs constantly appear and then disappear, canceling each other out. The aforementioned event horizon is important for the generation of Hawking radiation, because it occurs with virtual particles created near the boundary and does not disappear, but due to strong gravity, one particle of the pair falls into the black hole and the other escapes. This continuously pumps out the energy of the black hole, which eventually causes the celestial body to evaporate over a period of time much longer than the age of the universe.

In their paper, the Dutch scientists prove that a black hole is not necessary to generate radiation.

We found that such radiation can also be produced in large quantities outside black holes near the curvature of space-time, where gravity separates particles.

says one of the study’s authors, mathematician Walter van Solijekum.

This means that such radiation can also be generated near objects below the event horizon, the remnants of dead stars, or other massive celestial bodies. After a very long time, this causes everything in the universe to eventually evaporate like black holes. This not only changes what we think about Hawking radiation, but also what we think about the future of the universe

Professor Heino Falk referred to the astrophysicist.

However, before we get into the idea of ​​final evaporation, let us keep in mind that all of this is speculative, that is, it is currently awaiting verification of the theory through observations.
