Just thought I should add. The models used to calculate the speed of gravity through gravitational dampening with respect to binary pulsars, I don’t agree with personally. It’s the best we’ve got at this point. Like you implied earlier. Theorists need more people who think outside the box. The boxes we’re in are leading to dead ends at this point.
So long as its not that dang box with the cat and flask of poison in it, I guess we're OK.
