I am working on a final project for my AP Physics class and must do some research on Relativity. I just have a few questions and was wondering if anybody could answer them for me. It would be greatly appreciated!

1. Assuming that traveling at the speed of light were possible, "time" would stop. Does that

imply then, that while traveling at a speed greater than light "time" would reverse?

2. If the answer to question one happens to be yes, then what would happen when "time"

reached zero for the moving observer? Would he cease to exist or continue to move

back in time living with two realities?

3. In the Twin Paradox, would the "younger" twin be physically younger, or just have

perceived a smaller time lapse?

If these could be answered, it would be awesome! Thank you in advance!
