Black holes keep ‘burping up’ stars they destroyed years earlier, and astronomers don’t know why::Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable ‘burping’ bouts. Half of all star-killing black holes may experience the same.
But it’s not a single point though, because blackholes with a different mass have different sizes, so it’s more like a “maximum density” that can exist in this universe…
It’s an oversimplification, but something with the mass of say, a human, will be crushed into a very very very very tiny space. A much smaller space than 0.1mm radius, which would hold Earth’s moon’s mass of 7.342×10^22 kg.
Yes… And something with the mass of the universe will crush into a significantly larger (yet comparatively tiny) volume of space… Thus, a black hole is basically the maximum density we can currently comprehend and theorize.
As far as i know the Mass of the black Hole is concentrated in the Center (singularity). But it is surouded by its schwarzschild Radius. Anything that enters it cant escape.
Well, unless it burps
Time slows down as the mass approaches the center, so it just can never reach it. It’s stuck in time dilation approaching infinity.
