"Hawking’s prediction that black holes radiate heat and eventually evaporate completely gives rise to the profound 'information paradox,' which asks what happens to information about the stuff that fell into them."

In a first, scientists took the temperature of a sonic black hole
https://www.sciencenews.org/article/f...
"To produce the sonic black hole, the researchers used ultracold atoms of rubidium, chilled to a state known as a Bose-Einstein condensate, and set them flowing. Analogous to a black hole’s gravity trapping light, the flowing atoms prevent sound waves from escaping, like a kayaker rowing against a current too strong to overcome."

What is a black hole?

"A black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull"
