I'm not sure if this is the right place to put this thread but... Are they possible? I have been watching alot of StarGate SG-1 and other movies that deal with these two issues. First I want to know if matter can be effectively molecularized and reassambled in its original form (anything - from a chair to a human), even if it's only a few feet across a room? And then (I think Einstien said it was possible) I want to know if time travel is possible and the (non-mathematical only explanatory part) theory of how it's possible. Do these two phenomenon take place in the 4th dimention? If so, how? I would appreciate any help.
