OK, so I have not read the whole paper, can't seem to access it so if anyone has it, please send it my way or at least a link too it. I understand the principles and with White coming out and proposing how to reduce the mass required I can see it being plausable, interesting at the least. Now, again, I have not read the paper and do not know if it covers this, but according to the special theory of relativity, those inside of the craft would get there much faster and age much slower than those of us here on Earth, thusly when they get back we would be older and possibly those that sent them would be dead. Again, I have not read this but the buzz is that it is not completely "trek-like" and that the factors of "warp" would be nearly limit-less. The weeeks or months to travel to Alfa Centuri as White was stating may be plausible, would that be for the observers or for the travelers? Further more, it is clear that the craft would travel exponentiallay faster than any communications capabilities that we currently possesses so is anyone working on any other theories taken from si-fy such as "sub-space" or any other coined phrase?

Here? http://arxiv.org/abs/gr-qc/0009013
 
Awesome! This tanker thanks you!
 
Damn, dt=dt. Assuming we can pull this off, that is cool for us here at home. Sounds almost too good to be true...
 
OK, so this has bugged me for a while about the equivalence principle and the black hole information paradox. If black holes "evaporate" via Hawking radiation, then they cannot exist forever. So, from my external perspective, watching the person fall in, they slow down, freeze, and redshift to "nothing," but never cross the event horizon. Does the equivalence principle say my perspective is valid? If it does, is it possible that that person really never crossed the event horizon? The...
In this video I can see a person walking around lines of curvature on a sphere with an arrow strapped to his waist. His task is to keep the arrow pointed in the same direction How does he do this ? Does he use a reference point like the stars? (that only move very slowly) If that is how he keeps the arrow pointing in the same direction, is that equivalent to saying that he orients the arrow wrt the 3d space that the sphere is embedded in? So ,although one refers to intrinsic curvature...
ASSUMPTIONS 1. Two identical clocks A and B in the same inertial frame are stationary relative to each other a fixed distance L apart. Time passes at the same rate for both. 2. Both clocks are able to send/receive light signals and to write/read the send/receive times into signals. 3. The speed of light is anisotropic. METHOD 1. At time t[A1] and time t[B1], clock A sends a light signal to clock B. The clock B time is unknown to A. 2. Clock B receives the signal from A at time t[B2] and...
