I bought a Powerball ticket for the $500MM lottery last Saturday, and was actually interviewed by a local TV crew when I bought my one ticket, and said something to the effect that $2 buys me several minutes of daydreams about buying ridiculous things (that $100k lake submarine in SkyMall magazine). Later I discovered a better reason for my purchase. In the many-worlds interpretation of quantum mechanics, every quantum event happens. It\’s basically the only way many can reconcile the EPR paradox or Schrodinger\’s cat being alive and dead. All possible alternative histories and futures are real, each representing an actual \”world\” or \”universe\”. Therefore, after buying that ticket, I actually won the $500MM jackpot in many of those universes. Unfortunately, in this particular universe I did not win the lottery, but, I can take comfort that many of \’me\’ did win, and my utility function somewhere among those universes is insanely high. For some reason, I\’m not enjoying that as much as I should based on the math.
