Physicists figure out how to retrieve information from a black hole

Black holes earn their name because their gravity is so strong not even light can escape from them. Oddly, though, physicists have come up with a bit of theoretical sleight of hand to retrieve a speck of information that’s been dropped into a black hole. The calculation touches on one of the biggest mysteries in physics: how all of the information trapped in a black hole leaks out as the black hole “evaporates.” Many theorists think that must happen, but they don’t know how.

I believe that the new thinking is that far from being invisible because no light escapes they are instead very bright from the energy from atoms being ripped apart in their vicinity.

Is that like an accretion disk

Pictures that is artists impressions I have seen make them look like projecting beams from both axis.

Good point, though a bit premature in that we don’t yet even have experimental verification that black holes do evaporate.
