Question

What was the question that einstein asked in his adolescence? ( "What would I see in a mirror if I held it in my hands and rao at close to the speed of light?")

and what was your answer?

Answer 1

It's very simple, if you're traveling at the speed of light no light would reach the mirror, so no light is reflected.

Secondly if you're traveling at the speed of light, no atomic, biological or mechanical process would occur, you wouldn't be conscious of anything so wouldn't see anything, not the mirror, your hands or even your spaceship.

It's like asking what you see when you're unconscious.

Good luck ✅.
