Illogical premise
So the whole movie is based on the "Avatar technology", but how exactly does it work? Sam W lies in a bed made of soft gel that supposedly transmits his consciousness to the avatar body temporarily.
How exactly is this possible? Does the avatar body have some kind of receiver or encoded chip in which his conscious resides? It has to be unlimited in range, since he travels far from where his actual body is resting in most scenes. Does the soft gel matrix transmit a signal of some kind or how does it work?
Has this been explained anywhere?
