Ignoring the whole destroy one body make another theme the idea of teleportation isn't at all possible with the current model of physics that we know.

It's impossible for anything that contains mass to reach the speed of light, this is due to mass increasing as speed increases (only noticeable once you achieve 10% of the speed of light) so to accelerate to the speed of light mass would increase to infinity.

This ain't really discussion material, the science behind it is impossible so unless we're completely wrong about physics teleportation is not possible.
