Also, think of the pressure waves. What happens when you teleport from place A to place B? There will be empty space left after you on place A (that will suck in the air from around you -- implosion. And you will be teleported to place B where some air already exists, probably. What will happen to it? Will the teleport "merge your molecules with the air"? Or will the air be fushed away instantly (explosion)?<br><br>What was a reasonably good concept, was in one of Terry Pratchett's Discworld books (you can read them all, it's worth it... This one is called Interesting Times), the wizards used some sort of teleporting by which they exchanged objects - the process teleported Rincewind far away and teleported something equally heavy (some animal, not spoiling much) back to them instead.<br>Although this was only about mass, the shape and its implications (empty space left and redistribution of the air's molecules) is still in question.<br>But they also dealt with the speed (relative to the Discworld) and the fact that the Disc rotates faster, the farther you get from the center...
