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.

If you can imagine easily, please help me!

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?

What do you say? Please help!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

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?

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

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.

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

@Sparsh Sarode What kind of Gravitational Properties?

@Harshit Mittal 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

@Sparsh Sarode Oh Thanks! I Guess You Are Right

Harshit Mittal - 5 years, 1 month ago

@Sparsh Sarode That's about it.

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.

@Ashish Menon 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.

Harshit Mittal - 5 years ago

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

Sparsh Sarode - 5 years ago

@Sparsh Sarode You may be right, I guess....

Harshit Mittal - 5 years ago

@Harshit Mittal Maybe because of gravitational properties of other stars surrounding it?
