After the first-ever image of a black hole confirmed theories posited by Einstein, it's the late scientist Stephen Hawking's turn to have parts of his life's work vindicated.
In a paper published in Nature, scientists say that have verified the scientist's namesake theory, Hawking Radiation, which hypothesized that black holes emit radiation from their surfaces due to a mix of different factors regarding quantum physics and gravity.
Theory - Scientists - Technion-Israel - Institute - Technology
To verify the theory, scientists at the Technion-Israel Institute of Technology turned to what sounds like mad science: creating their own black hole.
As reported by Gizmodo, in the absence of instruments capable of observing radiation around black holes from great distance, researchers turned to an analogue of the using a quantum material called Bose-Einstein condensate.
Material - Laser - Rubidium - Atoms - Hole
The material -- created by using a laser to trap rubidium atoms -- is similar to a black hole in that it creates a 'point of no return' except instead of consuming light, the matter affects sound.
Also like a black hole, sound, as a stand-in for light, has one of two options when encountering the material -- it can move away from or into the material, but once inside it can't escape.
Analogue - Hawking
The analogue produced exactly what Hawking had predicted.
While preliminary evidence of Hawking Radiation had been...
