Scientists refute Stephen Hawking’s controversial theory about black holes | international | News

In the 1970s, the famous British physicist, Stephen Hawking had an important exchange of views after confirming that there was an error in general relativity and in quantum mechanics, Two fundamental pillars of physics to explain and understand the universe.

The controversial concerns of Hawking, who died in 2018 after a long battle with amyotrophic lateral sclerosis (ALS), have been called. “The black hole information loss paradox”, but over time it became known as the “Hawking paradox”. So far, no one has been able to refute his approach.

Poetry or quantitative hair

In the 1960s, an American physicist, John Archibald Wheeler proposed the “No-Hair Theory” (No hair theory, in English), which simply says that black holes are bald because they lack information or have no distinguishing features.

However, recently, according to a study published in Physical Review Letters, Some scientists have found an answer to refute Hawking’s – and Wheeler’s – approaches to black holes, after showing that they have “quantum hair or hair”.

The team of researchers suggests that black holes are more complex than previously thought, and therefore hairy. According to them, when a black hole collapses, it leaves a weak trace in its gravitational field, which was called “quantum hair”.

Hawking refuted

On this occasion, Yes Poetry Theory aims to solve Hawking’s paradox by building a bridge between general theory of relativity and quantum mechanics, through a new mathematical formulation. In this way, the scientists make sure that they are not violating either of the two basic theories.

One consequence of Hawking’s paradox was that general relativity and quantum mechanics are incompatible. What we find is that they are very compatible.”The BBC’s Xavier Calmette, director of the investigation and professor at the University of Sussex, is reassured.

Our research shows that The two theories can be used to make consistent calculations of black holes And he explained how information is stored without the need for radical new physics,” Calmette added to Britain’s Guardian newspaper.

Despite what has been said, the discussion is not closed. Many scientists have been trying to solve Hawking’s paradox for several years. For the rest, there is no way to test the theory with astronomical observations: black holes have such a strong gravitational force that nothing can escape them, not even light, which makes them even more difficult to observe, study and study.
