Black Holes Aren’t Black After All, Say Theoretical Physicists

Black holes are a crucial part of the great cultural legacy of Einstein’s theory of general relativity. They have fascinated scientists and laypeople alike since they entered the public consciousness in the latter half of the 20th century.

But it may be time to say goodbye to the notion of regions of space so dense that even light becomes trapped within them. In the last year or so, an intense debate about the paradoxical properties of black holes has left a number of theoretical physicists, including Stephen Hawking, suggesting that black holes might not exist at all, at least not in the form that anyone had imagined.

There’s Nothing Black about a Black Hole

Is matter accreating on the surface of the black hole?

If matter is accreating do some black holes then blow it off when there is too much?

there is no “surface” to a BH. the event horizon, the radius at which the escape velocity = the speed of light, is solid. it is just a region.

ok, a region

the can be an accretion disk around a BH. and the matter in these can form Astrophysical Jets which is matter being ejected from the disk along its axis of rotation.

So if this new thinking is correct, it may one day be possible for our most powerful telescopes to actually see some black holes.
