The conversation between human and AI assistant.
If I could: travel, many times faster than light, to Mars, and travel back. Would I be able to see my past self travelling to Mars on the way back?
Hmm, that's true. Would it be possible for me to see myself on the way back though?
It depends on how fast you are traveling and how far in the past your past self is. There is a phenomenon called time dilation, where time appears to slow down the faster you travel. So, if you were to travel faster than the speed of light, you could technically travel back in time. However, this is currently impossible according to our current understanding of physics.
