Scientists Refute Stephen Hawking’s Controversial Theory About Black Holes

In the 1970s, the renowned British physicist, Stephen Hawking, generated an important exchange of opinions after assuring that there was an error in the theory of general relativity and in quantum mechanics, two fundamental pillars of physics to explain and understand the universe.

The controversial apprehensions of Hawking, who died in 2018 after a long battle with amyotrophic lateral sclerosis (ALS), were called “Paradox of the loss of information in black holes”, but over time it became known as the “Hawking paradox”. Until now, no one had been able to refute his approach.

hair or quantum hair

In the 1960s, the American physicist, John Archibald Wheeler had proposed the “no hair theorem” (no hair theorem), which simplistically says that black holes are bald because they lack information or have no distinctive features.

However, recently, and according to a study published by the journal Physical Review Letters, Some scientists have found an answer to refute Hawking’s -and Wheeler’s- approaches to black holes, after having shown that they do have “quantum hair or hair”.

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

Refuting Hawking

On this occasion, the so-called “yes hair theorem” aims to resolve Hawking’s paradox by building a bridge between the theory of general relativity and quantum mechanics, through a new mathematical formulation. In this way, scientists ensure that they do not violate either of the two essential theories.

“One of the consequences of Hawking’s paradox was that general relativity and quantum mechanics were incompatible. What we are discovering is that they are very compatible.”assured the BBC Xavier Calmet, director of the investigation and professor at the University of Sussex.

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

Notwithstanding 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 through astronomical observations: black holes have such a strong gravitational force that nothing can escape from them, not even light, which makes them even more difficult to observe, study and study. understanding.
