Understanding Distance Measurement in Time

The video explores the concept of measuring distances using time, a method we use daily without realizing it. Examples include describing travel times between locations in minutes or hours. The video further explains how this concept applies to astronomical distances, like the moon being 1.3 light-seconds away. It also introduces the idea of measuring time using distance, such as the length of a movie in feet of film.
