Recent research on black holes may help solve one of the fundamental problems of physics. Black holes are mysterious objects with an infinite density at the center, which is called a singularity. Their gravity is so powerful that nothing, not even light, can escape beyond their outer boundary – the event horizon. Because of this, they remain invisible to us.
However, a new study published in the journal Physical Review D suggests that we may have misunderstood the nature of black holes. According to this hypothesis, black holes may be nothing more than “frozen stars” – hypothetical objects that mimic the properties of black holes but have no singularity or event horizon.
If this theory is confirmed, it will not only change the way we think about black holes, but will also help solve the paradox proposed by Stephen Hawking regarding information disappearing in black holes. “Frozen stars” may exist as superdense objects without singularities that can reproduce the observed properties of black holes, states Ramy Brustein, one of the study’s authors.
According to classical theory, black holes radiate energy due to quantum effects described by Hawking. This process, known as Hawking radiation, eventually causes the black hole to lose energy and completely vaporize. However, in this scenario, all the information contained in the black hole disappears, which contradicts the laws of physics that state that information cannot be destroyed.
If black holes are frozen stars, this paradox can be resolved. Instead of the existence of an event horizon and singularity, these stars would be superdense objects that don’t allow collapse to a point of infinite density. Thanks to string theory, they will retain information that reaches them without destroying it.
Frozen stars, according to Brustein, can absorb almost anything that approaches them, similar to black holes. They can also emit gravitational waves, and these waves could be used to confirm the existence of such objects.
This hypothesis raises questions about our understanding of black holes, but opens up new ways to investigate their nature. The detection of gravitational waves could help scientists test this theory and solve one of the biggest mysteries of modern physics.
We previously reported on how black hole jets caused stars to explode.
