By using a chain of atoms to simulate a black hole's event horizon, researchers have shown that Hawking radiation may exist just as the late physicist described.
But detecting the hypothesized light directly is something astrophysicists are unlikely to ever achieve. Firstly, there are the considerable challenges posed both by traveling to a black hole — thebeing 1,566 light-years from Earth — and, once there, not getting sucked in and spaghettified by its immense gravitational pull.
In the absence of a real black hole, physicists have begun looking for Hawking radiation in experiments that simulate their extreme conditions. In 2021, scientists used a one-dimensional row of 8,000 supercooled, laser-confined atoms of the element rubidium, a soft metal, to create virtual particles in the form of wave-like excitations along the chain.
