1. Well, can I?

But seriously, how fast would I be going to travel a million light-years from Earth and make it back to Earth (where only five years has passed)?

Unless I fudged the simple math(which I may well have done..im tired)

The answer is you would have to reach a speed of 119916983200000 meters per second.

That would be the speed required to travel two million light-years, in the space of five human years.
3. no.
no physical object (at least nothing bigger than sub-atomic stuff) can travel faster than light.

And what of *speculative* FTL proposals like the Alcubierre drive and traversable wormholes?
