In Newton's Law of Gravity,     how do we know a value for "G"?       G is calculated from other fundamental constants based on the principles of physics.       It depends on what the masses are made from.     Only by experiment     We do not know how large G is.

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
