but with teleportation your not occupying the space in between you disappear and reappear in another location<br><br>"Teleportation is the theoretical transfer of matter or energy from one point to another without traversing the physical space between them"<br><br>so teleporting away from earth and escaping it's gravity well would be no problem little energy would be expended in the travel because you no longer occupy the space in between. Also the same applies to falling back to the earth would not cook them alive because they would not be occupying that space.
