Let's say we were to measure the force of gravity between two objects. Next we increase the mass of one of the objects by a factor of 6 (aka it is 6 times more massive) and decrease the mass of the other by a factor of 2 (aka it is 1/2 the original mass). How does the force of gravity in this new case compare to the original case? (aka how many times larger (value greater than 1) or smaller (value smaller than 1) is the force of gravity in the new case?

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.
