Hmm, I’d like to see the proof of how this works. I’ll have to ask my TAs or something.
Also, note that you can theoretically get a location no matter how far, within any time span, no matter how short, in YOUR frame of reference. IE, you could reach Andromeda in a year, your time. This is allowed in relativity because time is dilated and length is contracted for a moving reference frame. To an outside observer, you are approaching, but never reaching, the speed of light. That is, you cannot transmit information faster than the speed of light (to a stationary observer). Viewed from your own reference frame, what happens is that the length between you and the distant location is reduced by Lorentz contraction, and also your clock runs slower than outside clocks.

True, but it goes to show that it could definately be possible.
Unfortunately, it shows no such thing. Other experiments have been done where the speed of light was exceeded (superluminal ultrasounds: http://www.acoustics.org/press/150th/Mobley.html). The only common point to all those experiments is that no information can be propagated faster than light.
If we ever manage that, then we’d have a real breakthrough. The current experiments, while cool, amount to no more than parlor tricks. Cool to do, but with no practical applications. The techniques used don’t lend themselves to future improvements that would allow information to be propagated.
I didn’t intend the article I posted to directly show that faster-than-light-speed information propogation was plausible. However, it does go to show that what we once thought impossible or very technologically far off could really be just one breakthrough away.[/quote]
