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...
 
I asked a question here, probably over 15 years ago on entanglement and I appreciated the thoughtful answers I received back then. The intervening years haven't made me any more knowledgeable in physics, so forgive my naïveté ! If a have a piece of paper in an area of high gravity, lets say near a black hole, and I draw a triangle on this paper and 'measure' the angles of the triangle, will they add to 180 degrees? How about if I'm looking at this paper outside of the (reasonable)...
From $$0 = \delta(g^{\alpha\mu}g_{\mu\nu}) = g^{\alpha\mu} \delta g_{\mu\nu} + g_{\mu\nu} \delta g^{\alpha\mu}$$ we have $$g^{\alpha\mu} \delta g_{\mu\nu} = -g_{\mu\nu} \delta g^{\alpha\mu} \,\, . $$ Multiply both sides by ##g_{\alpha\beta}## to get $$\delta g_{\beta\nu} = -g_{\alpha\beta} g_{\mu\nu} \delta g^{\alpha\mu} \qquad(*)$$ (This is Dirac's eq. (26.9) in "GTR".) On the other hand, the variation ##\delta g^{\alpha\mu} = \bar{g}^{\alpha\mu} - g^{\alpha\mu}## should be a tensor...
