Stephen Hawking's Famous Black Hole Paradox Could Finally Be Solved

Stephen Hawking’s work has influenced many fields, including those of cosmology: most notably quantum gravity and black holes. He was the first to point out that ze black holes behave in a way that places two fundamental theories at odds with each other, relativity and quantum mechanics. This paradox has baffled scientists for half a century and caused some to question the fundamental laws of the body. Recently, scientists say they may have solved it, based in particular on the fact that black holes have a property they have called quantum hair of gravity. This would be an advanced standard in theoretical technique.

Black holes are objects cosmic that we do not yet fully understand. Thus, in astrophysics, a black hole is defined as an object so small that the intensity of its gravitational field prevents any form of matter or radiation from escaping it. In other words, their gravity bends space-time to the point that nothing can reach the necessary speed could escape. Such objects cannot scatter light, and are therefore black, which in astrophysics is terrible that they are optically invisible which.

De Similarly, information cannot escape, and a sober theory of Einstein’s general relativity suggests that data about what goes into a black hole therefore cannot soberly get out, i.e., we cannot determine what, the posteriori, entered the black hole. But quantum mechanics says it’s difficult. This is the information paradox highlighted by Stephen Hawking in 1976.

A key quartet of sober physicists, including a professor and sober research student at the University of Sussex, have co-authored two posts that could dramatically affect our understanding of black holes and sony ericsson would like an answer to the problem that baffles scientists for nearly half a century. The studies are published respectively in the journals Physical Evaluation Words and Physics Characters M.

Black holes and the information-based paradox

In a top temperature, let’s come back to the paradox over information. Hawking realized that black holes radiate in a special way. Their warping of space-time would alter the wave-like character of the surrounding quantum fields so that a form of thermal radiation would be produced. This means a black hole should slowly evaporate as one, putting kid energy, photon after photon, into the Universe. As it radiates, the black hole loses energy and therefore tone. Sober fact, general relativity implies that a detail could basically disappear in the black hole, the package over the evaporation over this one. Conversely, the laws of quantum shape state that information is preserved in black holes. This is where the information paradox lies. information was supposed to burn before entering a black hole, a sober theory a sober fuzzy ball darkinos in which black holes are assumed to have fuzzy boundaries. But most of these proposals required rewriting the laws of quantum mechanics or Einstein’s theory of gravity, the two pillars of the modern whole body.

Quantum hair

All theories that assume persistence data describes these remaining connections with the Universe as “hair”. This is why Xavier Calmet and his collaborators suggest that when matter collapses into the black hole, it leaves a faint imprint in its gravitational field. The authors named it the “quantum hair of gravity”, as their theory superseded an earlier idea called the absence of hair theorem, developed over the years . This theory of bald black holes, based on classical physical structure, asserts that they can be considered surprisingly simple objects, defined only by their mass, their electrical cost and their second kinetics, linked to their rate of turn.

Instead of simple objects, the authors claim that black holes are processed better. They believe that their quantum hair theory provides the mechanism by which data is preserved during the collapse of a black hole. This new remedy applies quantum thought to gravity in the form of theoretical particles called gravitons. These hypothetical elementary particles would transmit gravity in most quantum gravity systems, in the same way that the photon is associated with a potent electromagnetic force. Through a series of logical steps showing how gravitons could potentially be learned to behave under certain energy circumstances, the team demonstrated a model for how data inside a black hole can remain connected to surrounding space.

Specifically, the researchers compared the gravitational fields over two stars with the same total tone and the same radius, but different compositions. Classical sober body, the two stars have the same gravitational potential, but at the quantum level, the potential depends on the structure of the star. When the stars collapse into black holes, their gravitational fields preserve the memory of the structure of the stars and lead to the bottom line that black holes have hair. Data on matter falling into the black hole would leave a search for its passing, giving us access, theoretically, to the structure of the black hole.

The Professor Xavier Calmet, sober at the University of Sussex, exclaimed, sober exclusively for BBC Information : The capital problem has been solved!

Our option requires no speculative ideas; instead, our research demonstrates that both theories can be used to perform consistent black hole calculations and explain how to store data without the need for a radical new technique.

Nevertheless, there is no obvious sober way to test a theory with astronomical findings, the gravitational variances would be too small to be measured. . Sober as theory, it is interesting, based on the solid framework. But it must be the subject of a meticulous examination of a component of a scientific community.

Professor Calmet concludes on the subject sober of his discovery, in a press release: It will take temperatures for people to accept it. One of the consequences of Hawking’s paradox was that general relativity and quantum mechanics were incompatible. What we find is that they are quite compatible. It will therefore take time to get people to accept that it is not necessary to find a radical alternative to solve the problem
