Lab-grown black hole analog behaves just like Stephen Hawking said it would
They created a black hole analog out of a few thousand atoms . The absorbed photon has negative energy and subtracts energy in the form of mass from the black hole, while the escaped photon becomes Hawking radiation. From this alone, given enough time (much longer than the age of the universe), a black hole could completely evaporate away. [That's] just like being in a black hole, once you're inside, it's impossible to reach the horizon."
