After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a force, as Newton had believed, but the result of a ...

apparent FTL is not excluded by general relativity. Examples of FTL proposals are the Alcubierre drive and the traversable wormhole, although their physical plausibility is uncertain.

General relativity "describes how our universe was ... violent events could cause spacetime to shudder—a supernova, for example, or the titanic collision of two neutron stars or black holes.

When around 1916 Einstein first used general relativity to build a cosmic model, he followed the orthodoxy of the day and assumed that the universe was static: that is, neither expanding nor ...
