For the first time, the temperature of a black hole in a lab was measured

When they are called black holes, they are known to be places where the gravitational pull is so strong that even light cannot repel them. But in 2009, scientists created another black hole in a laboratory. This is a black hole that can not make a sound.

These sonic black holes are a good example of light-absorbing black holes. Scientists can now measure the temperature of such a black hole, and this study confirms Stephen Hawking’s prediction 45 years ago.

Hawking Radiation

In 1974, Stephen Hawking reported that black holes were emitting tiny particles from their horizons.

In 1974, Stephen Hawking reported that black holes were emitting tiny particles from their horizons. It is named after Hawking Radiation in honor of the person who first introduced these particles. Hawking said the temperature of the eruption was determined by the mass of the black hole. These emissions are similar in concept to black-body radiation, and their temperature is inversely proportional to the mass of the black hole.
