The model of time travel used in StickManStickMan was chosen to be as logically consistent as possible.
Travelling forwards in time for a hundred years is effectively the same as simply vanishing without trace for a hundred years and then reappearing. This presents no causal problems as far as paradoxes etc. are concerned. Travelling backwards in time has a completely different effect. Whenever you go backwards in time, your re-emergence into the real world "nudges" the universe onto a different timeline. This is because you have changed something: just by appearing in the past, that has changed the universe and you are now in a different universe from the one you began in. You are now free to kill your own grandfather etc. without fear of paradox, because this is a different timeline entirely. Basically, a man who goes backwards in time never returns to the universe he started from.
The StickManStickMan chronicles begin in Timeline A and follow the adventures of the guys who were born in that timeline, known as the "A-guys". (There are of course infinitely many other guys, whom we don't follow.) In accordance with the theory, whenever the guys travel backwards in time, the universe diverges in two. So far in the chronicles they have travelled backwards in time three times, creating Timelines B, C and D. Currently they are in Timeline D, and if they ever travel back in time again they will presumably end up in Timeline E.
NOTE: comics occur roughly on the date they were first uploaded, but not exactly. Obviously, it's not as if 24 hours pass between each comic, or each conversation would go on for weeks.
It's a confusing diagram but it's fairly easy to follow the guys' journey. First, trace down Timeline A, ignoring divergences, until you reach the point in 2002-A when they first jump backwards in time. Now go backwards in time and shift over into Timeline B, then carry on tracing down, this time all the way to 3001-B. Go back again, and shift over to Timeline C. Follow down to 2033-C and jump back again, into Timeline D.
There are a few references to what happens differently in the timelines that the guys leave behind, included to clear up some temporal plot holes which I discovered while I was putting the timeline together.
|Creation of Universe -1.
