She set out one day In a relative way, And returned on the previous night. Reginald Buller Faster-Than-Light Travel is a staple of Space Opera that allows an "out" to the unfortunate fact that space is honking bigmaking it impossible within physics as we understand it now to get anywhere remotely interesting within the average lifetime of a civilization.

Today, it is widely understood that in order for the protagonists to be able to plausibly visit a new Planet of Hats every week, they need to travel through space at speeds faster than that of light itself. The problem is that as far as present-day science is concerned, going faster than — or even just as fast as — the speed of light is, for all human intents and purposes, impossible.

See Analysis for more of this. Of course, writers may wave away the issues surrounding FTL travel by invoking incredible advances in future technology, or they may simply not worry about the complications too much at all. In either case, explaining how people may travel from Earth to the edge of the Galaxy in less than an hour will generally involve equipping a Cool Starship with some kind of "exotic" propulsion systemwhich, approximately, holds the normal laws of physics in abatement.

This is the Faster Than Light Drive.

The exact mechanism varies, but more detailed works may explain how the system avoids the lightspeed limitation. There are three broad favorites: Ship waves hands very very fast and can thus go faster.

Distinguished by the ship still traveling in normal space just like a conventional drive, with all the hazards that may entail. Only to an outside observer it would appear the ship is moving impossibly fast.

Most notably used in Star Trek where the warp drive actually compresses space in front of the ship while stretching it out behind it. Some simplify it as the ship is riding a wave warp of space, not unlike how a surfboard rides a wave of water.

Ship disappears and reappears elsewhere. Functionally, a ship using one does not travel faster than light; instead, they alter the distance that has to be traveled, generally to about zero. Sometimes called "fold drives" from the analogy of folding a piece of paper to make two distant points adjacent.

As the range is rarely unlimited the ship typically moves in a series of "jumps", needing some time to recharge or re-calibrate its engine between jumps, but the jump itself is generally instant making this technically the fastest method. Oddly enough this rarely uses Teleportation Tropes excepting perhaps Tele-Fragas those are personal tropes.

Notably used in Dune. Ship leaves local space and goes into another dimension where it can go faster. Usually called "X"space, with X usually being "Hyper" or whatever the drive is called so a Zerodrive takes you to Zerospace etc Maybe the laws of physics are different so you can go faster than light there.

Or perhaps hyperspace has weird topography so that by traveling for a day there you can reenter the real universe thousands of light-years from where you started.

Because travel still takes time it may take a trip in hyperspace exactly as long as it needs to but is still not instant. Has decent odds of being a scary place with its own hazards to manage. Most notable example can be found in Star Warsthough the picture above is actually only of entering hyperspace.

The actual Technobabble explanation for FTL travel in works that use this "restricted" flavor of the trope can still fit into any of the above categories. The important distinction from a story-telling perspective is that our protagonists first have to use conventional, comparatively slow travel to reach some special location before they can warp away across the galaxy.

This may lead to the existence of "choke points" where Standard Starship Scuffles may take place, or tension-building delays during a trip. Hyperspace Lanes may or may not apply: This concept can also be seen as the inverse of the No Warping Zone.

Whatever the nature and form of FTL travel, many works will try to come up with some appropriately snappy name for it. The most generic term for an FTL drive is probably the "hyperdrive", but many books and series come up with their own terminology. It should be noted that any particular name used for FTL travel does not necessarily have to correspond to a specific means of travel as described earlier in this article.

Similarly, Babylon 5 used the term "Jump Drive" to describe moving in and out of an alternative dimension, hyperspace, where ships could cross interstellar distances in a short time, rather than instantaneous travel between two points in real-space.

For example, Jump or Hyperdrives may provide a very easy but often dramatic way to escape an antagonist because it is usually hard for anyone to track a ship that just disappears; exactly what Applied Phlebotinum allows the ship to do so is less significant.

A Warp Drive, on the other hand, usually does not allow the same escape option; we may get a Stern Chaseinstead. Often, the exact mechanism by which FTL is achieved is only important insofar as it supports various kinds of Phlebotinum Breakdown. Exotic FTL drives also give us an "out" against inertia: Since the laws of physics are being held in abeyance, we can safely assume that if the drive breaks, the laws of physics reassert themselves, so it is impossible to "coast" at superluminal velocities see Space Friction.

Thus, we can effectively ensure that Space Is an Ocean. It is generally assumed that FTL travel is for travel between star systems and furthermore, it is the only viable means of travel between stars. Conversely, subluminal, conventional travel is for use within a star system:Thorne's research has principally focused on relativistic astrophysics and gravitation physics, with emphasis on relativistic stars, black holes and especially gravitational waves.

He is perhaps best known to the public for his controversial theory that wormholes can conceivably be used for time travel. However, Thorne's scientific contributions, .

An Einstein–Rosen bridge, or wormhole, is a postulated method, within the general theory of relativity, of moving from one point in space to another without crossing the space between. Wormholes are a popular feature of science fiction as they allow faster-than-light (FTL) interstellar travel within human timescales.

But “time slows down close to the speed of light”, and indeed at the speed of light no time . July 7–8 is World Firefly Day!
