This simulation created by researchers in the Netherlands might help us know more about mysterious black holes. Black holes are the most mysterious cosmic objects that NASA has ever studied. The most intriguing thing about a black hole is that gravity and spacetime are so strong that even light can’t escape.
Scientists have created simulated black holes to help their understanding of the phenomenon. These scientists have used a chain of atoms in a single file to simulate the event horizon of a black hole and experienced what is known as the “Hawking radiation.” The researchers believe that the simulation can help resolve the friction between two conflicting frameworks that describe the universe i.e. the general theory of relativity and quantum mechanics.
For a unified theory of quantum gravity, the relation between these two theories needs to be found first. Black holes may be the answer to this question. When something enters a black hole’s event horizon, what happens is unknown. However, Stephen Hawking said that the interruptions to quantum fluctuations caused by the event horizon of a black hole are quite similar to thermal radiation.
As per Hawking radiation, if a black hole loses more mass than it gains, it will eventually vanish. It is the theoretically made black hole analogs that can help us learn some things about the behavior of a black hole in a laboratory. The team led by Lotte Mertens from the University of Amsterdam in the Netherlands has done something different.
They tried to analyze the properties of Hawking radiation and were quite surprised when the black hole analog started to glow. This shows that an entanglement of particles in the event horizon is necessary to create the radiation. “This can open a venue for exploring fundamental quantum-mechanical aspects alongside gravity and curved spacetimes in various condensed matter settings,” the researchers wrote in the Physical Review Research.
