Memory is a funny thing. It's not linear. We remember things in random chunks at different times in our histories. You might have a memory of an event from childhood in one moment then in the next you'll have a memory from adulthood. The two memories may or may not be related, however the two different time jumps in a matter of moments proves memory is not linear. Traveling throughout time is like remembering events in random order. We see an event that might have happened in 1947 and then a similar event ten years later. A fraction of time has passed from one moment to the next, ten years in memory. Time travel may or may not be a process of gaining memories. Just a thought.
