:This view of time is a fictional one made popular by sci fi movies, but it is not correct. We use the concept of time to measure things, so we can say that one event happened before or after another, but there is no indepenent "Space-Time Continuum" (like in Back to the Future) that exists seperate from everything else. "Time" is not an entity or a "4th dimension", it is merely a concept we use to describe sequences of events. The ticking of a clock or the aging of a person are two examples of events which occur 'over time', but you need to have events to be able to measure their duration, or to have any concept of Time, just like you need to have a physical object to be able to measure its length. There are no '10.5 metres' floating around in space, or '75 degrees celcius', or '16.95 gallons', there are only physical items which have these measurements, just like there is no 'Time' except for the duration of events.
