Newton predicted that if the sun is gone the planets would instantly fly out of their orbits. Drifting off into space in a stright line. Newton thought the gravity was the force that acts instantaniously across any distance with mass or volume.
Einstein saw a big problem with Newtons theory a problem that aroused from his work with light. Einstein knew that light doesn't travel instantaniously in fact it takes 8mins for the suns rays to travel to 93mill/miles Earth. He shown that nothing, not even gravity can travel faster than light. How can the Earth be release from its orbit before the darkenss resulting from the from the sun's absence reach our eyes?
Anything that outruns light is impossible that ment Newton. the 4D of space a single Dimention of time has bond togather a frabric of space. To understand this Einstein has to use geometry to understand this. Things move along this fabric of space time. Like the surface of a trampoline. Is morph & strech by heavy objects like stars

Its this morhping and curving of space time that creates what we feel as gravity. Not because the sun instantly grabs hold of Earth's orbit. But simply because they follow curves and bendings by the facial fabric by the curve of the sun presents.
The sun is gone, The gravitational disturbance would result that forms a wave that would travel across the facial fabric in much of a way that a pebble drops in the pond. Makes ripples that travel across the surfave of water. We wouldn't feel the change of the orbit around the sun. Until this wave reaches the Earth. Einstein calculated that ripples travel exactly the speed of light.
WHAT DO YOU THINK ABOUT HIS THEORY I BELIEVE HIM!??????????????????????????

I think that gravity doesn't travel and is a constant unwavering force. If the sun suddenly disappeared (hypothetically), I think that the gravity would instantly disappear with it and planets would fly in whatever direction they were moving at that moment.

Gravity is a force that exists between celestial bodies,but it's influence takes time to take effect.
The length of time is the same as the speed of light.
If the sun disappeared it would take 8 minutes for the effect to cause earth to fly off at a tangent.

Well I think that You r mistaken at a point that gravity "travels".
Gravity Can be said as a force which attracts Things towards itself and light can travel from a source.
Now for your ? I think That the force of gravity and speed of light are nearly same.If u like my reason then choose as the best.

if the sun were to disappear the planets would orbit as usual until the *information* (absence of gravity) made it to the planet. gravity travels at the speed of light. traveling at the speed of light you experience no time. so as far as the photon (or gravity wave in this case) is concerned, it was instant.

no . as far as i know light travels faster than gravity

hmm...thats a noodlescatcher.....
ah hah!
gravitiy is a force
force is there but not there.....
light is a wave,not a force.....
force .......
luke use the force
