>It takes 100s of thousands years travelling at the speed of light to get from one end of the galaxy to the other. The crazy thing is that at a constant 1g acceleration you could get to the Andromeda galaxy in your lifetime. Andromeda might be 4 million light years away, but relativistic effects mean that only about 30 years would pass for you. Of course, constant 1g acceleration would require an unimaginable amount of energy (and something to thrust with). At 1.5g-s you could make it in 20.
