Gravity is the universal force. Not only does it stop us getting above ourselves, it keeps Earth orbiting around the sun, our sun swinging around the centre of the Milky Way, the Milky Way in a merry dance around its neighbours, and so on upwards. It is actually the weakest of nature's four forces, but whereas the other three - electromagnetism and the strong and weak nuclear forces - unleash their full strength only at the scales of atoms and particles, gravity conserves its power to trump all

Is gravity real time and instantaneous? Light takes 8 minutes to reach the earth from the Sun, but the gravitational pull of the sun on earth is real time.

Theoretically Gravity radiates at the speed of light or real close to it.

I could be wrong but I believe the Moon orbits the Earth in the same sense as the Earth orbiting the Sun but does not rotate in the same sense as the Earth rotating and creating our day and night. This is the reason for the name "Dark Side of the Moon" and the reason why the "Man on the Moon" is always visible.
