The propagation of gravity is something neither i or many others have even been aware of. Even the thread and the article are titled in such a way to say "Gravity travels at the speed of light" not the propagation....which is later mentioned in the article. It's completely ass about face.....lol

The article was quite obviously talking about the speed of gravity, as in it's propagation, not the force of acceleration exerted on an object by it.
The title isn't misleading either.

Then once we saw that the sun no longer existed (since the lighted had stopped reaching us) we would stop orbiting, since space-time would have reverted to a flat-state. Its cool, but also insane. It means technically speaking, we would orbit NOTHING for about 8 minutes.

Yes.
