I think you misunderstood my plan, which was to start at the moment when the Powerball jackpot is announced, jot down the numbers, and then travel backwards in time exactly one hour and ten minutes, long enough to purchase a ticket just before sales close. I then jump back to my original time (one hour later) and watch as the numbers are drawn, with my winning ticket. Thus “the past” and “the future” you’re referring to are only an hour apart. This is specifically to minimize the various effects upon causality which you’re talking about.
