Yes, Moving Clocks Run Slowly, but is Time Dilated?
Year: 1991
Keywords: moving clocks, twin paradox, time dilated, gravitational field
If anything in modern physics can be said to have attracted the most attention, it is surely the topic of time dilation, along with the associated "twin paradox." Many experiments with varying degrees of precision demonstrate conclusively the phenomenon that moving clocks run slowly. These experiments are here elucidated in enough detail to remove any doubt about the existence of the phenomenon. That said, the question arises whether this means that time is "dilated," or whether "clocks" run slowly simply because they move through the gravitational (or other) field. There is, in fact, a rational basis upon which to decide the question.
