lets do some hands on science on Aug 31 next year, at the eclipse to see whether light (or the absence of it) arrives earlier than the gravity max, or waves!
Saintberthold, as a saint you should know, that the "speech of angels" or the head deity is a an infra-sound transmitted through a magical non medium. "Gravity waves do not require a medium and can propagate in a total vacuum". neither does the electro-magnetic radiation. the waves of photons. May be "god" used not photons but gravity phonons? ( this is classed as humour after all)
bohm: The signal they measured was emitted from a source 1 billion years ago and the universe is about 13 billion years old; the cosmic microwave background is much much older. That is why I said, " the light we see now ", implying that no light could escape from the original obscure bb condition, that should have seen a tsunami of gravity expanding, barely keeping pace during the inflationary period.
