Document Summary

Einstein"s second revolution: two probes launched out of your free-floating ship in, space can be curved and this idea lies at the heart of opposite directions could meet each other. Einstein"s 2nd revolution a revolutionary view of gravity contained in his general theory of relativity. What are the major ideas of general relativity: special theory of relativity no gravity involved, special relativity tells us that the 3 dimensions of space and the 1 dimension of time together form an inseparable, It isn"t a mysterious force that acts at a distance. The presence of mass causes the distortions, and the resulting distortions determine how other objects move through spacetime. The stronger the gravity, the more slowly time runs. Black holes can exist in spacetime, and falling into a black hole means leaving the observable universe. The universe has no boundaries and no center, yet it might still have finite volume.
