Physicists Simulated a Black Hole in The Lab. Then It Began to Glow.

Using a chain of atoms in single-file to simulate the event horizon of a black hole, a team of physicists in 2022 observed the equivalent of what we call, which describes the behavior of gravity as a continuous field known as spacetime; and quantum mechanics, which describes the behavior of discrete particles using the mathematics of probability.

If this Hawking radiation exists, it's way too faint for us to detect yet. It's possible we'll never sift it out of the hissing static of the Universe. But we can The effect of this fake event horizon produced a rise in temperature that matched theoretical expectations of an equivalent black hole system, the team said,The simulated Hawking radiation was only thermal for a certain range of hop amplitudes, and under simulations that began by mimicking a kind of spacetime considered to be 'flat'. This suggests that Hawking radiation may only be thermal within a range of situations, and when there is a change in the warp of space-time due to gravity.
