I know there are many ways in detecting a black hole, but there are odds against them too. So I wanted to know a accurate method to detect a black hole.
Here are the known methods to me and the odds I think
One is by observing a dark region of space where even photon particles are missing and other is by detecting the X rays emitted from the black holes from our reference (say earth)
- If we decide to tell there is a black hole in a specific space by the absence of light, because black hole doesn't allow light to pass over them. The odd is that one can say that there is no nearby star producing enough light or can say that the light is not reaching the reference.
- If we decide to tell there is a black hole due to X rays emitted from it, one can say that the atmosphere in reference place is absorbing the X rays and not allowing them to get detected.
So is there any way other than these two to detect a black hole in space accurately?
