+Tom Scott Well put and indeed, superheros could do a lot more if it wasn't for the highly limited imagination of the human mind. But teleportation is a tricky thing. I'm no expert or a physicist for that matter but if I understand your version correctly, you're basically disintegrating every molecule and atom in your body, transport them at a tremendous speed and get reassembled else where, somehow. That has a huge risk to it, I think. If your mass is maintained through this journey, travelling at a speed closer to the cosmic speed limit will increase your mass exponentially. In a way, you will distort space-time and slowing time around you. Your bits and pieces start collapsing onto each other, completely destroying the information required to put you together (i.e. the chemical bonds and macromolecular shape or orientation and what not). If your speed is fast enough, you'll compressed into a singularity. YIKES! In my opinion though, it will be more efficient (for a lack of a better word) to replicate the quantum state of your constituents at that time instance and build a new you. That way, you can completely avoid turning into a goo smeared on a hunk of rock traipsing somewhere in the universe or worse. Love your shows BTW
