How can we see a blackhole if light doesn't come back from it

I believe a black hole is indicated by an absence of light. So say you have a picture of a galaxy, and there's a black spot where no light returned, that's a black hole. It's black cause naturally the color black doesn't reflect light

Exactly. Scientists identify black holes because of the compete lack of light radiation. However, I'm not sure if they can be identified by using other forms of radiation such as infared, gamma or xray.

we dont see one, rather we infer its presence by its absence

looking at a space with so many stars, when we see a patch of darkness scientists infer that its a blackhole!!!

It distorts light, and things can still orbit around it without being sucked in.

That's how the science guys do it.

the absence of light/background I imagine

you have to hold up a mirror and look over your shoulder . . also wear a pair of night vision goggles

Because we cant see the stars that would be behind it or around that area.
