case study;Relative to itself, a reference frame is at rest and experiences neither length contraction nor time dilation. An astronaut on a speeding spaceship does not see his own rulers shortened nor his own clocks running slow. Rather, it is the man on the ground who sees the rulers on the spaceship shortened and the spaceship's clocks running slow. Also note that there's nothing wrong with the clocks and rules. Space itself is shortened and time itself is slowed down for a moving reference frame, relative to the stationary observer. These interesting effects, which have been verified experimentally many times, are all derived from the two basic postulates mentioned above.

The mathematics of Special Relativity tells us that as a reference frame moves at ever higher speeds, its space contracts ever smaller and its time becomes ever slower, relative to the stationary observer. In the limit that its speed approaches the speed of light in vacuum, its space shortens completely down to zero width and its time slows down to a dead stop. Some people interpret this mathematical limit to mean that light, which obviously moves at the speed of light, experiences no time because time is frozen. But this interpretation is wrong. This limiting behavior simply tells us that there is no valid reference frame at the speed of light. A reference frame that has exactly zero spatial width and exactly zero time elapsing is simply a reference frame that does not exist. If an entity is zero in every way we try to describe it, how can we possibly say that the entity exists in any meaningful way? We can't. Space and time simply don't exist at and beyond the speed of light in vacuum. Therefore, taking the limit towardscsimply reaffirms the two postulates.
