Einstein’s relativity states that gravity propagates at the speed of light.
How can a black hole have a gravitational field when gravity propagates at the speed of light?

Wow! thanks for the insight and reference, and wonderful quotes.
I thought it was of particular interest that the phrase "Once formed, they and their gravity just are." was used. ???
No gravitons would be available, if gravity was not a force; but the effect was from another (non-force) cause.
thanks again
