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.

Describe the difference between someone who is accelerating and someone who is only moving at a constant velocity. A person moving a constant velocity will ‘feel’ how fast they are moving. A person accelerating does not feel the acceleration. A person who is accelerating will ‘feel’ that acceleration, but the person moving at constant velocity will not feel the motion. Both of the above. None of the above.
