Black hole surface area
WebSep 8, 2024 · A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. Matter and radiation fall in, but they can’t get out. Two main classes of black holes have been extensively observed.

WebAug 29, 2024 · A black hole is an area of such immense gravity that nothing -- not even light -- can escape from it. Click here to download this video (1920x1080, 116 MB, video/mp4). Download a poster of this … WebWe actually define r to be the circumference of a circle centred on the black hole divided by 2 π (i.e. the circumference is 2 π r ). That means the area of a sphere of radius r centred on the black hole is 4 π r 2 by definition. So the surface area doesn't go to zero then go negative. Sorry :-)
