I'm trying to figure out several methods of FTL, that are actually theoretically possible.

ALSO, What would be a viable method of high-speed travel, particularly in a Dyson-sphere (Well, A chunk of one anyway)?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

  • $\begingroup$ Hi, CaptClockobob, welcome to Worldbuilding, sorry if this hasn't been the warmest of welcomes, but questions about FTL travel are asked often & aren't well received. Despite that, you asked about theoretical FTL, which is sensible, because science allows for some theoretical modes of FTL, but that doesn't make them real. Here there is generally a strong line against FTL. It's takes time to learn ropes here. Don't let this discourage you. WB keeps its standards high. This produces quality answers to questions. Hope you understand. $\endgroup$ – a4android Sep 19 '16 at 4:55
  • $\begingroup$ A suggestion: the part of your question about high-speed Dyson sphere travel is better fit for being a question in its own right. Please give details about the structure of your dyson sphere to help answers. Dyson spheres come in several varieties: dyson swarms, dyson shells, dyson bubbles, etc. For more information try en.wikipedia.org/wiki/Dyson_sphere $\endgroup$ – a4android Sep 19 '16 at 4:59

There are a few theoretical proposals for faster-than-light phenomena. There is absolutely no guarantee they will lead to faster-than-light travel.

The basic theoretical FTL methods include: --

  • wormholes
  • the Alcubierre drive
  • Krashnikov tubes

It is recommended you look at previous questions on Worldbuilding SE for further information. See above for URL.

The Wikipedia entry on Faster-than-light is a good startling point for research. It will lead you to the theoretical concepts listed above.

This is a popular question and gets asked here often.
