I don't know why all you people are spending so much effort trying to iron out time-travel paradoxes, when it is such a ludicrous idea in the first place. Why do I say this? Consider the fact that whenever anyone jumps through time in any time-travel scenario I've ever heard of, they wind up in the exact same location as they left, IN RELATIVE SPACE. That is, Marty winds up in the same earthly location he left, when every nurd worth his keyboard knows that the Earth is spinning at 25000 miles an hour, flying around the sun, which is spinning around the galaxy, etc. Marty should be out in space somewhere! (sorry, I'm excluding The Time Tunnel, where the heroes always landed in exactly the spot appropriate for the time they were landing in, i.e. Philadelphia in 1776) Steve Upstill

Time and space are two different dimensions. If you travel through time, you SHOULD end up in exactly the same spot you were in "before" you left.

The problem is that the Earth would still be millions of miles away from that same spot since the Earth *moves*. Thus he would be in the same place floating in empty space, and he would have to wait 30 years for the Earth to get there! -- Sarima (Stanley Friesen) {trwrb|allegra|cbosgd|hplabs|ihnp4|aero!uscvax!akgua}!sdcrdcf!psivax!friesen or {ttdica|quad1|bellcore|scgvaxd}!psivax!friesen

Time and space are two different dimensions. >If you travel through time, you SHOULD end up in exactly the same spot >you were in "before" you left. Which same spot??? The spot relative to the center of the universe, galaxy, sun, earth, etc. ? The universe is expanding, the milky way is spinning, the earth is orbiting the sun, the earth is spinning on its axis... etc. If this spot moves in respect to time then a time machine must also be a space travel machine. Perhaps this is hinted at in the movie, ie. that's why the Delorean get so cold when it re-enters from time travel. As Khan said, "It's very cold in space...". Let's not get too analytical, say to yourself "It's only a movie... It's only a movie... It's only a movie..." then drink 2 pan-galactic gargle-blasters and send me mail in the morning.

So how do you define "the same spot"? -- Peter da Silva (the mad Australian werewolf) UUCP: ...!shell!neuro1!{hyd-ptd,baylor,datafac}!peter MCI: PDASILVA; CIS: 70216,1076

Actually there's a good rationalisation of that: since gravity effects percieved time, and the flux capacitor takes advantage of this fact (assumption), then there is no reason it can't throw you around in time so long as you stay in the same place relative to the nearest large mass.
