On the surface of the Earth, a hammer and a feather are dropped from the same height at precisely the same moment. The feather impacts the Earth first because the force of gravity is weaker on the lighter feather. The hammer and feather both impact the ground at the same time. The hammer impacts the ground first because it is heavier than the feather. The feather hits the ground after the hammer because of air resistance.

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
