Ok, there's a small chance that I may be working on a project sometime soon that would involve describing some types of FTl travel.

As part of it I would need to describe at least a few different types of FTL travel that worked in notably different ways.

Now, I've heard serious scientists talking about drives that expand space behind a vessel while contracting it in front of the vessel. Where are some sites where I could get more info on this, along with how the people inside the ship might perceive the effect. I would imagine that everything behind them goes black as no light is catching up to them from behind, while the front...Well, with the blue shift and all god only knows what it would look like to look forward while such a drive was going.

I've also heard of the "descriptor drive" that postulates that every particle in the universe can be described mathematically, and that if it were possible to manipulate those descriptors you could instantly change a ship's position in the universe. The processing power required along makes the mind boggle, but are there any sites discussing the issue?

Likewise, there are other postulated forms of FTL travel, can someone direct me to serious sites discussing them and possible side effects? I do NOT want to get into the whole "FTL IS IM/POSSIBLE!!!" mire, OK? I'm just looking for sites that postulate plausible, or at least plausible seeming, FTL possibilities.

Thanks, and god bless.
