Hi Duane

You are professing again that gravity is faster than light. It is not faster than light. Gravitational interactions between bodies is at the speed of light, and it doesn't matter how many times you assert it, it will not change the predictions of General relativity, which as we have seen has passed every test so far.

You are again looking at it far too simply and expecting a simple truth to emerge, when the reality is a bit more complicated to try to picture or explain. As far as I understand it, the gravitational waves from black hole mergers do not originate from within the event horizons, but from the region of space outside it. Indeed, if the physics is the same with regards light, then any wave emitted, be it light or gravitational, from the event horizon or below, will be Doppler shifted to an infinitely large wavelength by the time it leaves the event horizon. And as any 1st year physics student will tell you, a "wave" with infinite wavelength is not waving, and so cannot propagate. If it cannot propagate, it does not travel through space. This is how light, which has no mass, cannot escape the event horizon of a black hole.

So how does gravity from inside the event horizon communicate with objects outside. Well, it is because the concentration of mass-energy inside the the event horizon curves space-time - BUT the event horizon marks the point where the curvature of space-time is infinite. Hence it is actually form the point just above the event horizon that communicates the gravitational field, not what is below. That is how gravity seemingly can escape a black hole. In General relativity, it is not escaping, but rather the mass is affecting space-time outside the event horizon which is what other bodies then react to.
