in back to the future, ya know when the car has to go 60mph in order to go into a future dimension. ok, that makes sense, but what i don't understand is how the car can still be going 60mph when it reaches the other dimension. theoretically, the car should be at 0mph once it enters the future world, so it would just do a massive burnout instead of truckin along at 60mph. these are the thoughts that keep me up at night.

If you want to move through space time, then accelaration is not the answer. Yeah, you can go pretty fast, but not forwards in time as time slows down at high speeds (meaning light speed). The wormhole would have to be created by mass. A large star gains enough mass to puncture space, thus creating a balck hole, a hole to another dimension. 88mph in four dimensions (lengh, width and depth plus time) would not. But i'm sure after the film was released enough people went to 88mph to see if they could time travel. The simpletons never fail to amuse.
