"<a href=""https://www.youtube.com/watch?v=zJt8yzR2aoY&amp;t=1m38s"">1:38</a> Teleporting to space and back should ignore gravity", escape velocity, heat, etc. Those are properties of matter in relation to other matter... We're not talking about traveling from point A to B at any speed here (if that were the case, traveling instantaneously to any point through atmosphere would rip your atoms apart). The whole point of teleportation is ignoring matter entirely; taking one material object, essentially removing it from spacetime in one place and having it reappear somewhere else, no need to worry about gravity/acceleration or the matter between here and there. What you would need to worry about would be instant changes in pressure (like earth atmosphere/gravity to space, or from sea level to the bottom of the Marianas Trench) you could be crushed or catastrophically depressurized etc.
