I have been gone from the forum for a while, and this looks like a good place to jump back in.
Nobody has mentioned what is obvious to me. Time and space are not separate things. One second is a distance of approximately 186000 miles. We have a lot of momentum in "time", and I agree it would be impossible to pull a U-turn, travel for "years" of distance (186000 miles/second), and then pull another U-turn to align ourselves with the direction (time) we were going before, all in a matter of seconds. Ain't gonna happen. We can't just jump ourselves from one location to another, whether you think of it as time or space is irrelevant. However, there is no reason we couldn't circle "back". It would just take longer than the distance covered.
Semantics can be tricky. The same words can mean different things to different people.
P.S. - Anyone in S.W. Calgary got a doob to smoke with me? I have none right now...
