Gravitation and spacetime Hans C. Ohanian
Publisher: WW Norton & Co

One needs the full theory of quantum gravity but it's generally believed that it can't help us to eliminate the singularity as a violent and irregular end of the spacetime, anyway. The observations are a powerful test of Einstein's theory of general relativity, which says gravity can bend space-time, the fabric that shapes our universe, and the light that travels through it.

They call it “lensing” because gravity acts just like the lens in your eyeglasses, bending the path of the light–except instead of bending the light with glass, gravity is actually distorting the curvature of spacetime itself. Flat space-time and negative space-time describe an environment in which the Universe is non-compact, with space extending infinitely, forever in time, in any direction. "None of us can know what the world is, in the way that we used to know it. From: Geoffrey Klempner Subject: Space, time and gravitation after Einstein Date: 5 February 2008 12:20. Einstein says that time is not the same for all of us, but different, for each one of us. Spacetime, Geometry and Gravitation book download.
