I'm trying to categorize all the theorise currently out there on how to travel FTL and avoid light speed limit, does anyone know where I can find links and what not and would anyone like to discuss it all in general?
All I remember is Alcubierre's theory involving negative energy to warp space time and some other theory that sent a ship to another dimension where the rules were either different or non existant.

You want actual theories or sci-fi-not-really-based-in-physics theories?
Cause I'm not sure I've heard any theories of the former sort on avoid the speed of light, but there are lots of the latter sort. Warp and hyperspace being two of them.
Edit: Ooops, Forgot about wormholes (eg, Stargates). Silly me. Wormholes are a more valid theory. There isn't any experimental evidense for them per se, but the math works out quite nicely (IE, it their existance can't be excluded mathmatically) and the theory is not impossible. Their existance is widely hoped to be likely.
I don't want to say that they are considered likely because so far they are really a mathmatical theory and no more. So even if we physicist personally believe they exist we're not supposed to say they do until there is evidense for them Posts: 3295 | Registered: Jun 2004

Real theories, like ones that haven't been debunked by the entire scientific community as poppycock. Like ones that seem like they could work.

Well, there are some solutions to general relativity which involve closed time-like loops; that's time-travel to the likes of you, and mathematically equivalent to going FTL. Most of them involve easily found objects like infinitely long, infinitely dense cylinders rotating at lightspeed. But that's math; in actual physics, you could probably make do with a mere light-year, density of a neutron star, and 99.9999 percent of c. A mere engineering problem.

Gah. Blayne, that's annoying enough on CK chat; do you think you could keep it out of forum posts?

You know, for the longest time I had no idea what you meant, so I didn't click on the link. Then I thought it meant "For the lose" as my friend says. I see I was wrong. No matter, go on with you argument.

Somebody else was very kindly occupying the attention of Hungary and Georgia with his aggressive posturing. Posts: 10645 | Registered: Jul 2004

Might wanna take a look at Cramer's columns on SpaceDrives and GeneralRelativity, then google up some more explanatory pages-with-diagrams using the names&jargon found there.

No, I was thinking of someone rather closer to Italy, who insisted on divvying up the Balkans his way.
