Don’t let yourself get amazed too easily. Einstein said some dopey things, particularly about gravity.

whereas it is well known that gravity propagates instantaneously to within our ability to measure it.

Wendy1946 has said some mighty dopey things about Physics here at FR. Like: "There’s never been a “big bang”, the universe is not expanding, and if dark matter or dark energy could be detected, it would not be dark. For that matter if the stuff were actually 95% of the universe as claimed, you’d be vacuuming it up off your carpets four or five times a day."

You're dead wrong about gravity affects being transmitted instantaneously - it is well known that gravity works at the speed of light just like all other fundamental force phenomenon.

Not being familiar with every last thing Einstein had to say about gravity, I can't say he didn't make any goofy statements there, but let's just say I hold him in slightly higher regard than you on the subject. (Massive, light-bending sarcasm there in case you didn't catch it....)

Incorrect. If this were true, gravitometers would point at the apparent position of the sun in the sky instead of at the true position, which is ahead of the apparent position, as they actually do.

Incorrect. If that were the case, then gravity would not bend light. Since it it measurably true that gravity does bend light, the speed of gravity is faster than the speed of light.

How much faster, I do not know. But it is faster.
