Is a black hole invisable?

Answer 1

The blackhole itself is invisible, but the matter that is sucked down by the black hole emits, while falling to it, radiation such light, X rays and ultraviolet, that can be detected. It is called the Hawking radiation. This is the only way to detect black holes by telescopic observation.

Answer 2

It can be detected by the huge gravity pull on the matter around it and the fact that it could have an accretion disc around it like a whirl pool of gas being sucked in too it. The light would not be visible because not even this can escape Black Holes.

Answer 3

a black hole is not neccasarily invisible, just how it works makes it invisible.

basically, it suks in everything near, but before it is engulfed, it is distorted, stretched, etc..

this counts for visible light, say from the sun, so when light reachs it, it disapears and is suked in

and without the light, we are not able to see the actual black hole, only a cluster of stars and objects orbiting it

Answer 4

If u're wondering whether you can see it, the no. Because it literally sucks in the light around it, so you can never see it through a telescope. However, you can still locate them though. They have a massive gravitational pull and you can locate them by finding distinct areas in the universe where there should be a massive object due to orbiting satellites, but there is nothing.

Answer 5

No. Distinctive radiation is emitted from the junk orbiting around the black hole.

Answer 6

Yes. It is said that gravity of the black hole is so strong, even light cannot escape.

Answer 7

no light escapes it so the hole itself is invisible

Answer 8

It is until something provokes it and it starts to suck it in. That is the only time you can "see" it, and by "see" I mean visible light. What the others said is correct about the other types of radiation.

Answer 9

No, but once you see it you'll probably be too close and be KILLED lol.
