 Apparent FTL is not excluded by general relativity; however, any apparent FTL physical plausibility is speculative.Examples of apparent FTL proposals are the Alcubierre drive and the traversable wormhole.In the context of this article, FTL is the transmission of information or matter faster than "c", a constant equal to the speed of light in vacuum, which is 299,792,458 m/s (by definition of the meter) or about 186,282.397 miles per second.
