In 1974, researchers were able to develop in the laboratory a theory predicted by physicist Stephen Hawking.
In 1974, Stephen Hawking described black holes, the darkest gravitational giants in the universe, as objects that astronomers could not have imagined, but could now emit light on their own, calling this phenomenon “hawking.”
The problem is that no astronomer has observed Hawking’s nigu radiation, and they have never been observed because they were predicted to be very faint. That’s why scientists are now creating their own black holes.
Researchers at the Technion-Israel Institute of Technology were the only ones. They created a black hole similar to thousands of atoms. Scientists have tried to confirm two important predictions by Stephen Hawking, namely that Hawking’s radiation does not appear anywhere, that their intensity does not change over time, and that it is stationary.
“That’s what we wanted to confirm. We really succeeded.”
“A black hole should radiate like a dark body, which is a warm substance that emits constant infrared radiation. Hawking commented that black holes always produce a special type of radiation. Jeff Steinhover said.
The black hole, which was developed in the laboratory, was composed of about 8,000 rubidium atoms, which were cooled to almost zero and placed with a laser. Atoms created a nigo state of matter called the Bose-Einstein condensate, which allowed thousands of atoms to act like an atom.
“This is what happens in a black hole”
Using a second laser, the researchers generated energy energy that flowed like water from a waterfall, creating a horizon of events in which half of the gas flowed faster than the speed of sound and the other half. In this experiment, scientists searched for a pair of phonons instead of a pair of spontaneously formed photons in gas.
The slower half of the phone can move against the gas stream, while the faster half of the phone is trapped due to the speed of the supersonic gas, Steinhover explained. “It’s like trying to swim against a current faster than you. This is what happens in a black hole.
The researchers conducted the experiment 97,000 times
Once the pair of phones are found, researchers need to confirm whether they are interrelated and whether Hawking radiation remains constant over time, i.e., whether it is stationary. That process was complicated, because every time a picture of a black hole is taken, it is destroyed by the heat generated. Therefore, the team tested 97,000 times, taking 124 consecutive days of measurements to find correlations. In the end, their patience paid off.
“We have shown that Hawking’s radiation is static, that it does not change over time. That is what Stephen Hawking predicted,” Steinhover added. find out.
