The idea is that nothing can escape the black hole, not even light - so they might be quite dark. However, if matter falls into the black hole, it gets accelerated so much, before reaching the event horizon, that it emits a lot of radiation - as a result, some "black holes" are among the brightest objects in the Universe! For more information, read the Wikipedia article - or some other sources - about quasars.

After whom are non-rotating black holes named?
Schwarzschild black holes. Named after the scientist who proved mathematically black holes can exist.
Are black holes named like hurricanes?
no
How did blackholes get their name?
black holes have such great gravity that nothing, not even light can escape them. That is why they were named "black holes".
Can black holes be other color?
black holes don't really have color... they just named it "black hole" because no light can escape from it... neither do anything else, for that matter.
How are black holes named?
The only "named" black hole is called "Cygnus X-1", for the first X-ray source in the constellation Cygnus.
After whom are non-rotating black holes named after?
Astronomer and physicist Karl Schwarzschild provided the first exact solutions to Einstein's field equations in the year the latter's General Theory was published (1915). Spherically symmetric non-rotating black holes are sometimes called Schwarzschild black holes.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
How did black holes in outer space get their name?
Since nothing, not even light, can escape black holes, they are invisible (so to speak). You can only see a black hole when it is sucking up light, since the object with light looks like something is pulling it away.Actually, there isn't much imagination in this. Black holes are named as such because they are, basically, holes in the universe which emit no light.
Who is rotating black holes named?
Roy Kerr, a mathematician from New Zealand, discovered the solution to the equations of general relativity that describes a rotating black hole.
Is the universe made of black holes?
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Can black holes dies?
Black holes do not die but they can evaporate.
Why are black holes round?
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
