Scientists have therefore started creating artificial black holes inside labs to study their properties.
Scientists made the impossible possible. Black holes are born in laboratories. Stephen Hawking’s prediction 47 years ago was absolutely correct. Maybe as little as possible. black holes also radiate light. That radiation is called ‘Hawking radiation’.
The exciting study, by scientists at the Technion-Israel Institute of Technology, was published in the science journal Nature Physics. In the first week of March.
That’s what Hawking said in ’74
The former idea was that the gravitational force of a black hole was so strong that no object around it could ignore that tension. Everything is forced to fall into the black hole. Even light cannot survive his hunger.
Ignoring the gravitational force of a black hole, the photons of light cannot come out. In order to avoid that tension, a particle of light or an object has to run faster than the speed of light. Which is impossible. So black holes cannot be seen. That ‘monster’ is covered in darkness.
Hawking was the first to point out in 1974 that there was something wrong with the idea. Black holes can also emit light. No matter how small he is. That is Hawking Radiation.
47 years later
the birth of a black hole in the laboratory, scientists have shown that everything Hawking said about black hole radiation 47 years ago is correct. They found that black holes also emitted Hawking radiation. He also observed that the intensity of radiation did not increase or decrease with time, Hawking said.
How was the black hole born in the laboratory?
The researchers cooled the gas flow of 6,000 rubidium atoms to absolute zero temperature (below 263 degrees Celsius). Then held the frozen gas flow in place with a laser beam. It gave birth to a strange state of matter.
Whose name is ‘Bose-Einstein Condensate (BEC)’. In this state, thousands of atoms of matter behave like a single atom. With another laser beam, the researchers were able to disperse the rubidium gas like shower water. That’s how the black hole was born, in the laboratory.
Researchers, however, used phonons, a sound wave-particle, instead of photons in the laboratory.
