Theoretically yes it is possible. When you travel at the speed of light, time slows down. Realistically, not right now. After figuring out how to travel at the speed of light you would then have to deal with the black hole you would cause, and in case you didn't know, nothing can escape from a black hole, not even light. But who knows, there might be an "easier" way to go to the future.
not within the forseeable future
No, time travel isn't possible.
just go up!
The correct form is 'was'. 'Were' is in the plural and only one person is represented by the statement, making it incorrect. If you are talking about a possible or probable past then the correct form is "If I was your man..." E.g. "If I was your man, why didn't you tell me?" [conditional past] If you are talking about a possibility or imaginary situation in the future then the correct form is "If I were your man..." E.g. "If I were your man, I would bring you roses every day." (I'm not your man, but if I were...) [possible future] "If I were a woman..." (I'm not a woman, but if I were...) [imaginary / impossible future]
no
You can't, time-travel isn't possible.
No, since the testicles are still in the body of the man.
Debatable. Some would say hynotism is a form. In the future it may become possible if man ever uses 100% of their brain.
