Where does the energy go if you are already moving when you teleport? Do you somehow lose all mass for a brief second? Instant transportation from point A to point B means that there is no in-between state to change the variables of nature. Zero time passes between being here one second and there the next.
Most everything that has mass and is moving has momentum. If momentum were to somehow be cancelled, which it can’t be, your body would probably just stop completely. Even electrons have mass (9.1093837 × 10-31kg) and just stopping all electrical signals in your body at the same time seems like a bad thing. (I say “most everything”, because there are these strange things called photons. It doesn’t have mass, but has momentum. It’s also a particle (err… “energy packet”?) and a wave, which is even weirder.)
Sure, we are taking about a completely fictional situation when it comes to teleporting so this conversation is just really just a thought experiment.
If you were granted any wish, but you only received an extremely literal version of that wish, what are the consequences? That is humorous to think about, actually.
