I’m not sure that is the case. If it were then the gravitational force between the sun and planets wouldn’t be perpendicular to their orbits but have a component opposing their motion.

So you're saying gravity acts as if it were a rigid "arm" that connects two bodies, as opposed to something that propagates through the intervening space between them? i.e., like flying cars in an amusement park ride physically attached to the rotating mechanism at the center?

The speed of gravity is faster than the speed of light.

If that were not the case, then black holes would not be able to capture and bend light.

I think that’s a good analogy.

Gravity seems to be a property of matter, like a field of mutual attraction that surrounds all matter in proportion to its static mass, so that there’s nothing that actually ‘travels’ as such but is always present.
