WARNING: A VERY RETARDED QUESTION

Ahem.

In actuality, the prospect of time travel as presented by science fiction is completely impossible. To suggest that time is made up of events that continually repeat themselves is to misunderstand the very nature of chronology. One cannot return to the past and revisit the happenings therein, because those happenings are finished and done with, a once-in-history event that cannot be duplicated. One could, however, make the argument that mankind is continually engaged in time travel, as we hurtle through the chronology of our lives at breakneck speed, endlessly moving from one moment to the next. In the last twenty-four hours, for example, we have travelled forward through time exactly one day. An interesting point, however, is that the actual speed we move through time often seems disproportionate. For example, this lecture started roughly ten minutes ago, whereas it feels more like three hours. Similarly, if you were engaged in viewing your favorite television program, half-an-hour may have seemed like scant seconds.
