Time Scales

As a writer of science-fiction I often have to think about the time scale of future history, which wraps around and has me thinking about the time scale of actual history.

For example take a hypothetical person born around the time I was 1960. (I was not actually 1960 but it good enough for an example.) If that person lives until they are 80 they die in 2040, that an interesting stretch of history. Now say that person has a grandchild or great-grandchild born when in 2030. The kid and the oldest hang out for ten years because the oldster has cool stories before personal computer, home video, cell phones and so on. The kid born in a better time has a better run and dies when they are 90, or 2120. That kid, when they die, has spoken with and interacted with a person who was alive before man flew in space, but is passing away in the 22nd century.

With the rapidly expanding abilities of our medical technology there’s no doubt those number are on the conservative side. To me this gets more staggering when you play these numbers against history.

Move it all back and we have someone passing away in 2020 who had direct contact with someone born in 1860. That old person in 2020 could very well have known someone who had born on a plantation as a slave. That’s how tight and close our history truly is. Things and events we think of as the distant past are really just barely one step removed from living memory.

It is staggering.
