Why do gravitational waves propagate at the speed of light?

[QUOTE="Giulio Prisco, post: 5476365, member: 593379"] Saying that entanglement and the expansion of space "travel faster than light" is misleading, because entanglement and the expansion of space can't be used to send faster than light (FTL) signals (that the expansion of space can't be used to send FTL signals is evident, that entanglement can't be used to send FTL signals is a proven result of quantum mechanics). Gravitational waves are solutions of Einstein's field equations of general relativity, which predict gravitational waves traveling at the speed of light. The recent detection of gravitational waves from merging black holes (LIGO experiment) seems entirely consistent with general relativity. [/QUOTE]
