Can you explain for me what part of general relativity says that gravity must go outward from the body at the speed of light, rather than instantly?
I realize that Einstein believed nothing could go faster than the speed of light, but is there evidence that this must be so in the case of gravity? I wonder, if there is no graviton, that there may be no reason to think that massive bodies don't curve space-time around them continuously. Consider, for example, how Einstein refuted entanglement, but was found to be incorrect.
(In this, I know there is one case of indirect evidence of gravitational waves, but one example does not give strong evidence, and there could be unforeseen problems in explaining the observational results.)
Again, to sum, what exactly is it in general relativity that requires gravity to perpetuate at the speed of light. ("Because nothing can travel faster than the speed of light." is not an acceptable answer.)
