Whether an electron (-) is an electron (-) or a positron (+), and a proton is (+) or (-), is the physics equivalent of a local, relative, personality issue based on environmental-physical circumstance or situation. In the quantum cloud (at all telescoping of the cloud to infinities) and unobserved it (mirrored matter and energy) is essentially an "integrated" personality . . . an integrated entity . . . probably obedient to Newton's first law.
If the universe keeps self-repairing itself, eternity to eternity, is it ever the same universe, including position and momentum, instant to instant, moment to moment?
A knowledgeable, discerning, historian will give this answer to that question, "Yes, history always repeats itself in large though rarely, if ever, in discrete local detail . . . doing it all of the time; for all time."
Sorry Bill, but you lost your bar bets eternities ago. Eternities ago, including future history, the future past.
Of course, you can keep mum about it for a good while longer and no one will ever know you already lost ("entropy" actually meaning "in turn" or "return." as "universe" means "a turning unit and/or 'unity'").
