It has just occurred to me that this latest observation settles a particular scientific dispute for good; namely, the question of does gravity have a speed limit?
Some hypothesized that gravity 'travels' (if that is the correct word) infinitely fast from the mass while others hypothesized that gravity 'travels' at finite speed c.
Since now (from the OP link) ...[text shortened]... ] gravitons exist? Or is there STILL some scientifically credible way for NO gravitons to exist?
Originally posted by @moonbusBut we know those waves travel damn close to c. Theory says anything with zero mass can go exactly at c and that seems to be the case with these waves. BTW, when the first set of detections happened, they calculated a full sun's worth of energy, that is to say, all the energy available say in fusion reactions or matter-antimatter reactions, was put into making the gravity waves so it started out as a very powerful event and what we got is just the echo of it spreading through space and time.
