How fast is Gravity?

The moon is moving away from the earth at 1.6 inches a year.

There is a gravity is everywhere theory:

Moreover, with the pushing gravity model, there is no need for the singularity concept, because the pressure at the centre of a black hole depends on the nearly constant gravitational field of the Universe, so gravity does not increase infinitely. (If it is presumed that gravity is totally absorbed on passing through the mass of a black hole, the pressures at the centre of a small

Not a proton size!!! Minimal mass of a black hole is at least 1.4 Sun
and a huge black hole should be the same.)

That's because, like I said, The Moon is being "Thrown" by the Earth. Then Pulled back Toward. Thats why I said "Falling Around" the Earth. If it is moving away, it just means that it's momentum is stronger than the Earth Gravity, by an insanly small fraction.

If I recall correctly Gravity is thought to traval at the speed of light, I remember seeing a PBS documentery on string theroy they used the senerio of our sun just blinking out and not exploding to explain

with neutons theroy earth would feel the loss of the suns gravitational pull instantly and shoot off in to space before we even noticed the sun was gone.

however Einstiens therory of relitivity shows that at we would notice the loss of the gravitational pull of the su at the same moment as we see the sun blink out. so being no physist im guessing that means gravity travels at the speed of light .

How strong is gravity.

On earth gravity accelerated at 32ft/sec/sec, if the Moon
is a million miles away, the distance squared means there
is hardly any earth gravity on the Moon's surface.

The nearest star to the sun is light years away.

In between stars there is very little gravity.

So anti gravity propulsion can't be the ET secret to space travel.
