Message: <blockquote data-quote="EzekielRaiden" data-source="post: 8353505" data-attributes="member: 6790260">The line between "teleporting" and "really fast travel" is impossible to settle cleanly. Asimov's hyperspace, for example, is a form of stutter teleport; despite not being instantaneous from one star system to another, it's made up of a sequence of instantaneous jumps. "Folding space" on one end is literally teleporting (you merge your destination point with your starting point), and on another just travelling through a faster/distorted space (B5 hyperspace, Mass Effect's relays) while using normal engines.As others have noted, physically speaking, FTL travel is all inherently a bit dodgy when compared to time travel too, so that's a thing. (Even the IRL-theoretically-possible Alcubierre drive is subject to "possibly enables time-travel" concerns, but there's a conjecture that if you try to, it'll cause a devastating energy buildup and explosion that would prevent actually succeeding.)So: there are multiple different ways (wormholes, gateways, Heart of Gold-style "visit every point in the universe" stuff, "folding space," instantaneous hyperspace travel) that produce zero-time translation between points, aka instantaneous travel/"infinite" speed. Slapping down all of them means excluding a number of non-instantaneous methods as well, potentially skewing the results heavily.Long story short? There are a lot of sci-fi methods to travel instantaneously. And even if you don't consider ones that allow instant travel, there are a bunch that are so close to instant that it's effectively instant, or could eventually be made effectively instant with sufficiently advanced tech. In Asimov's Foundation and Earth, for example, Golan Trevize's fancy-shmancy ship has a state-of-the-art jump calculation system, allowing it to do things hyperdrives couldn't do before--among them, making fewer, longer jumps between locations, giving it utterly unprecedented speed. In theory, if you had an advanced enough computer, you could make just a single jump between any two points, it would just be so fantastically difficult a calculation as to be impractical.</blockquote>
