how I know I really in blackhole,because I think we not have any light here?

Question

i also need to know, how to see the singularity point of blackhole???

Answer 1

You'll know that you're in a black hole because your body will be ripped apart atom by atom due to the tidal forces generated. And then, at the singularity even the atoms of your body will be shredded to form the 'quantum foam' which *is* the singularity.

Answer 2

We can't really see blackholes in the first place. We can certainly see their effects, however. Similarly, a singularity cannot be seen either. You said it correctly when you referred to it as a point -- an infinitesimally small thing where a lot of stuff goes. The only way to "see" one would be to calculate one mathemetically.

If your question was really "how can I tell I'm in a black hole versus an isolated universe", you should be able to tell by the differences between your legs (if you were falling feet first toward the hole) and arms or head, especially if you reached the point where your legs were being torn apart before your head.

You could also attempt to measure Hawking radiation (someone else made a reference to this). Hawking radiation is the process of virtual particles creating and annihilating themselves just beyond the event horizon of a black hole such that one particle falls into the hole and another escapes. To conserve the conservation of energy, the black hole loses energy and the virtual particle that escaped becomes 'real'.

Answer 3

There are a few ways I know of detecting a Black hole
1 when the black hole is feeding an other sun the gas falls in and you can detect this as in the super massive black hole in the centre of the milky way.
2 is do with the lensing effect of gravity when a Black hole passes in front of distant star the light Will be bent around the Black hole like a lense pretty cool really I guy spent years trying to get a photo of it it final manged it.
You cant see the singularity as light can not pass beyond the event horizon and as such we can not see any thing beyond this point

Answer 4

the presence of a black can only be identified by studying the the behavior of the near by stars,and or by studying the Strong x ray field that these emits. other than this the presence of the black hole can only be found when Ur being sucked in.

Answer 5

If you read the book by Stephan Hawkins, he talks about radiance caused by them.

Answer 6

Uh? What are you talking about?
