# Black Holes

Imagine you are standing in front of a convex mirror or a simple metal spoon (looking at the convex side). What will you see?

You will see your funny image. You can see your funny image formed most probably at the center of the mirror.

The same image is predicted if we go in front of a black hole.

My question is that: Is the black hole a convex mirror? We just can't see it easily because of no sunlight falling on it or is the prediction done by many of the physicists wrong?

My guess is that black hole is black because it absorbs the spectral light from its surroundings. Since no ray reaches the retina, it is black. Then how can we see our own reflection if it absorbs all the light?

Please Make it easy or elaborate

Ok. Now, how do we see a reflection? It is when the light contain the spectral colours in specific proportion hits our retina. Now, a black hole absorbs all the spectral colours surrounding it. Then no light excites our retina due to which we cant see a reflection. Thats what I think.

Ok! Let us assume for some time that the Black Hole Does not absorbs light, Then why do we see that funny image if we go in front of a black hole.

- 2 years, 5 months ago

That's because of the bending of the light near black hole which appears like concave/covex mirror reflections

You may be right, I guess....

Maybe because of gravitational properties of other stars surrounding it?

For reflection light need to reflect and come back towards us to see it.But in a case of a black hole,it absorbs all the light so we can't see the reflection, that's my guess.

If we can't see the reflection then How do we know that there is a black hole?

- 2 years, 6 months ago

The huge gravitational pull if black hole influences everything around it.So the motion of celestial bodies around a black hole we can calculate it's approximate position. Also the black hole appears as a void in space.

We see what's around it and guess it's there.

I think that a black hole is usually spotted using its gravitational properties....

- 2 years, 6 months ago

What kind of Gravitational Properties?

- 2 years, 6 months ago

Suppose that there r some stars near-by a black hole... Then all the stars' motion will affected by the black hole's pull... Using this, they try to locate the black hole... I am not sure, but I think this is the indirect method they use to locate a black hole
