Stephen Hawking was right: & # 39; Black Hole & # 39; Made in a lab confirms the late physicist's predictions about radiation, scientists say
- Researchers say they have confirmed the existence of Hawking Radiation
- In an experiment, scientists made an analog with a black hole that traps sound
- The analog seems to confirm that systems such as black holes emit radiation
- Research can have implications for what is known as the Black Hole paradox
After the very first image of a black hole confirmed theories posed by Einstein, it is the late scientist Stephen Hawking & # 39; s turn to get parts of his life's work confirmed.
In an article published in Nature, scientists say that the scientist's theory, Hawking Radiation, has verified that black holes emit radiation from their surfaces because of a mix of various factors related to quantum physics and gravity.
To verify the theory, scientists from the Technion-Israel Institute of Technology turned to what sounds like a crazy science: creating their own black hole.
Scientists hope one day to be able to study the radiation from a black hole, which is currently too far away to collect instruments to collect data.
As reported by Gizmodo, in the absence of instruments capable of observing radiation around black holes from a great distance, researchers are turning to an analogue of using a quantum material called Bose-Einstein condensate.
The material – made with the help of a laser to capture rubidium atoms – is similar to a black hole because it is a & # 39; point of no return & # 39; creates, except that it does not use light, but that it influences the sound.
Even as a black hole, sound, as an in-position for light, has one of the two options when it encounters the material – it can leave or in the material, but once inside it cannot escape.
The analog produced exactly what Hawking predicted.
Although preliminary evidence of Hawking radiation was observed by the same researchers in 2016, their second and most recent experiment was able to confirm a series of radiation characteristics.
Among the new observations were measurements of the black hole analogue thermal spectrum and the wavelengths produced, both of which corresponded to Hawking predictions.
In a separate attempt, scientists were recently able to present a black hole for the first time ever and perhaps have now unlocked a secret about the mysterious phenomenon.
& # 39; As I see it, we saw that Hawking's calculations were correct, & # 39; Steinhauer said Gizmodo.
Research results also seem to have implications for Hawking's theory of the Black Hole paradox, which wonders whether matter consumed by a black hole is completely lost.
The paradox pits general relativity against Hawking & # 39; s discoveries related to quantum physics. While the theory of relativity dictates that energy cannot be destroyed, but transferred, Hawking radiation seems to suggest that it can be eliminated.
How to reconcile this paradox remains a constant debate between theoretical physicists.
As far as Hawking Radiation is concerned, the recent experiment provides the strongest evidence for its existence that has ever been documented, but it still does not meet absolute evidence because no one has ever been able to observe the phenomenon in a real black hole.
Researchers say they intend to continue the experiment in the hope of gaining even more insight into how radiation can change over time until science is able to analyze the real thing.
WHAT IS THE BLACK HOLE INFORMATION PARADOX?
The information paradox, traceable to Albert Einstein, has fascinated Stephen Hawking and other physicists for decades.
In 1915, Einstein published the theory of general relativity that predicted that black holes can be defined by three main characteristics – their mass, charge, and spin.
In the 1970s, Hawking built on Einstein's work.
He said that black holes have a temperature and because hot objects lose heat, they would eventually evaporate and disappear.
The laws of quantum mechanics say that information is never lost, but that is a paradox for our current understanding of black holes.
Hawking wanted to know what happened to the objects that had previously fallen into the black hole.
He said that the idea of an event horizon, from which the light cannot escape, is flawed.
Physicists believe that while the particles falling into the black hole may have disappeared, their information lingers on the edge of oblivion in the & # 39; soft hair & # 39; of quantum particles.
In a new article, Black Hole Entropy and Soft Hair, Hawking and his colleagues discovered that if an object is thrown into a black hole, the entropy will change.
& # 39; Every object with a temperature also has an entropy & # 39 ;, Professor Perry wrote in an article in the Guardian.
& # 39; The entropy is a measure of how many different ways an object can be made from its microscopic ingredients and still look the same. & # 39;
The entropy of a black hole – or internal disorder – can be captured by these photons around the edge.
This information is released through a black hole when it evaporates.
However, this does not resolve the paradox.
Scientists still want to know how information is actually stored in soft hair.
They also still don't know how that information leaves the black hole when it evaporates.
