It's time to play "I don't know crap about physics".
If events in the future can influence the present, wouldn't people in the future try to harness that to influence the past?
It's impossible to read the OP without thinking of the "future Dwight" prank from The Office.
- dfranke 18y agoI think this is supposed to be the "fixed point seeking" theory of time travel, where the resulting timeline is one where any future impact on past events is such that it results in exactly the same future as the one which caused those changes to the past. Basically, applying a Y combinator to the universe :-). I had to phrase that really carefully to avoid having to invent new verb tenses.

- dfranke 18y agoIt's a poorly-written article so I'm not certain, but model 1.2 might be getting at the same thing that I'm describing. http://en.wikipedia.org/wiki/Time_loop_logic#Time_loop_logic http://en.wikipedia.org/wiki/Time_loop_logic#Time_loop_logic is a better description.
