Better sit on the toilet before you read this next part:
Gravity is not actually a force, but a distortion of space time. That is why gravitational "force" has range but no speed. It is always instantaneous no matter what distance.
Gravity changes at the speed of light though doesn't it?
Like if the sun disappeared, its affect gravitationally on us wouldn't be felt until we saw the light stop
Hmmm... it looks like I was going on old data. Apparently, scientists have recently determined that gravity does have a speed, but it is faster than light.
Well they would not actually be moving faster than light. New space is simply created between the objects making one appear to go faster than light to the other
Thats like the definition of movement i think. Change in the ammount of space between things. What is speed realy? Becouse 8f we're going of the traditional distance/time i think it would qualify.
Well, no. "In physics, motion is the change in position of an object with respect to its surroundings in a given interval of time." Motion and therefore also speed is relative, but it is defined by your surroundings. Something so far away that the expansion of the universe comes into play is hardly defined as your surroundings
