They're not "getting out" of a gravity well — they're bypassing it entirely! Why should they have to generate waste heat coming back down? They're bypassing the whole notion of "coming back down"!<br><br>Seriously, you're calling out comic book teleportation for not following the laws of thermodynamics? It's <i>teleportation!</i> That's the whole <i>point!</i> If you needed to expend the same amount of energy to teleport somewhere as you needed to get there the normal way, there'd be no point in teleporting unless you were on an interplanetary expedition (in which case it'd save loads of time)! Jeez, you might as well point out that it's FTL travel, too! Well, of course it is! IT'S TELEPORTATION!<br><br>I mean, I get that that you were just setting the stage for explaining why teleportation would be so useful, but it was an utterly unnecessary digression, because it was basically a tautology. We all know that teleportation lets you go anywhere using basically no time or energy input. <i>That's the whole idea.</i> You might as well have said "Teleportation allows you to teleport."<br><br>A better method would've been to skip that part entirely, skip straight to "what we can do with teleportation", and introduce each potential use by calling to mind a use that we often see in the media, explaining what unstated principles and abilities ("required secondary powers") such a feat would require, and then explaining how those principles or abilities could be applied to a more ingenious feat.,(reply>), +Katie Katie But that's exactly what it is, because superpowers exist only in fictional universes (which incidentally, probably do exist, given an infinite number of parallel universes) where our laws of physics may not apply, at least not in the say we know them.
