Assumes that teleporting involves moving,   Velocity and inertia.,(reply>), @Tricia McIntosh i like to think that teleportation just works based on the physics that we haven't discovered or understood yet.,(reply>), @Jack Aguirre considering how subatomic exchange constantly affects every particle of your body, next moment you might be considered entirely different than current moment you. On the other hand, however, there is an idea that there is nothing that can distinguish two identical particles, meaning that even an exact copy of you made down to the lowest level of material world might as well be you.<br><br>On that note: in about a decade we replace nearly all of our cells with new ones, made with different nutrients/matter. Considering how much a person can change in that timeframe, some philosophical schools, starting with fairly ancient ones, postulate that our past us are in fact already dead and gone many times over and we don't care, so there's no need to fret over yet another arbitrary point in time in the future we associate with our deaths.<br><br>Either way our notion of us is considered that way to be just a construct of our memory.,(reply>), If it involves moving then it's not teleporting, it's just moving extremely quickly.,(reply>), The issue with this is that the asteroid belt does not have that many asteroids and the ones that can actually hurt us are far away from each other and far away from us and we don't have the exact coordinates for the most part unless you look em up,(reply>), So no you would not have power over inertia unless you fall then teleport to a space Rock to push it to Earth rinse and repeat until it's on direct course
