A scientist made a small black hole and it started to glow

A group of physicists from the University of Amsterdam developed the Black Hole Event Horizon. The team used a series of atoms in one file to better understand how black holes work.

Its creation proved Stephen Hawking's 1974 theory that black holes emit a rare form of radiation. They conducted research on the characteristics of Hawking radiation by simulating a black hole in the lab. According to Science Alert, Hawking radiation occurs when "particles arise from perturbations of quantum fluctuations caused by the fragmentation of black holes in spacetime."

The fact that the radiation itself glows is due to a strange spatial anomaly, as the black hole's event horizon is said to lie at a point where neither light nor matter can escape.

This is possible within a certain range of the center due to its density, so this is unavoidable even if one tries to travel beyond the speed of light (or any speed in the matter universe). The bogus black hole event also caused a temperature rise consistent with theoretical predictions for comparable black hole systems, but only when part of the chain extended beyond the event horizon, as reported by the Science Alert.

As a result, it is believed that particle entanglement across the event horizon may play a major role in the production of Hawking radiation.
Under simulations that began by mimicking what was thought to be a 'flat' spacetime, scientists say the radiation was thermal only over a certain range of 'jump amplitudes'.

Therefore, there may be certain circumstances in which Hawking radiation is emitted thermally. This can only happen if gravity changes the distortion of spacetime.

"This may open up a site for exploring aspects of fundamental quantum mechanics beyond gravity and curved space-time in a variety of condensed matter environments," scientists from  Physical Review Research wrote in their published paper.
