I am interested in learning more about the Alcubierre warp drive. Although I've read every qualitative description imaginable plus Lillian Lieber's The Einstein Theory of Relativity, which gives a BRIEF introduction to the math behind GR, I am totally lost when it comes to the math. Although I realize that I will not be able to do the math (I'm a high school student), does anybody know of a resource that will make it a little more understandable?

As a starter, try Relativity Simply Explained, by Martin Gardner. It's an inexpensive paperback. You could also try Time Travel in Einstein's Universe, by Gott. The latter book is relevant because general relativity guarantees that any technology for faster-than-light travel is also a technology for time travel. I think some of Michio Kaku's popular-level books may discuss the Alcubierre drive.
 
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...
