Dammit, this is killing me! I've always loved the idea of teleportation, but with the all the things said about telekinesis, Ive grown a bit wary. Telekinesis is really catching on with me. But all this talk has caused me to formed a few other thoughts about teleportation in my head. And yes, I know you're trying to run on the movie's logic, but I want to ignore that for a few moments.
For example, why not teleport other objects? I mean, you can instantaneously change your own location at any moment, why not a soda a can a few inches away from you? With Jumper's logic, you kinda have to memorize the location, but perhaps you could develop your skills so that it could be that specific object and location. Which brings me to a minor gripe, why is it believed that telekinesis can be honed and developed upon, but teleportation can't? You're somehow bending the very fabric of space, I'm pretty sure you can develop it. Perhaps control the speed of the teleportation, the form of it, etc. There are probably a ton of things I'm not thinking about.
