I have two questions concerning gravity that I have never found a definite answer to.
The first: How is gravity detected from afar? I've read about scientists detecting gravity in the universe where there is not enough mass to be producing that much gravity. If the gravity can be detected or measured, how precise is the measurement?
The second: How fast does gravity travel (or the effect of gravity)? Does it behave like light or is it all together different?
