I didn't know where to put this, but sci-fi seemed fitting: Just a hypothetical regarding the Butterfly Effect that's been puzzling me, if anyone has any insight... How much could you do in the past before your very presence started affecting history? For fun, let’s say you wake up 12 years in the past, about... 45 minutes before a lottery drawing, having memorized the winning numbers. In that 45 minutes, would simply rushing to the store to buy a ticket (in, say, California) be enough to change the random trajectory of the little numbered balls in the rotating drum during the drawing? (Which takes place in Georgia). Note… I’m not talking about the whole “paradoxes” or “Time is self-correcting” thing, where one would go into their own timeline's past. We’re talking an alternate timeline, identical to the one you came from, up until the moment you arrive. Where your actions in this new world change its future (compared to the world you came from), causing a new timeline. You are (or rather, I suppose, your consciousness is) just a foreigner in this timeline. Any ideers? Is my fantasy plan for instant riches relatively solid, or am I doomed to appear in the past and instantly change the trajectory of some little ping pong balls on the other side of the country?
