The way you present a cyclical universe is like a perpetual motion machine.
I think anyone who has thought about cyclical universes in much depth has their own opinion on the subject. Personally I don’t much like cyclical universe models that end up looking like perpetual motion machines. In which one universe passes away, and then another one begins, and then that one passes away, and so on, and so on…forever. It just doesn’t seem very elegant to me. Not that elegance is an objective measure of accuracy.
But I like things that just somehow seem to make sense. Or at least makes me look at things in a way that I never had before.
So what I would really like in a cyclical universe model is one that explains why quantum mechanics looks and acts the way that it does. And how Everett’s “
Many World’s Interpretation” might actually be right. For the simple reason that all of those cyclical universes aren’t actually lined up end to end, but are instead stacked up one on top of another. With the beginning and end of each cycle being identical. And with no overarching space and time with which to differentiate them, they all occur at the same time, and in the same place. Such that they can interact with each other. And the observer doesn’t magically or randomly cause the wave function to collapse, but simply reveals which cycle they were always in to begin with. They’ve simply decohered their cycle, from all of the other cycles.
To me, that would be a cyclical universe model that I would like to see. One in which each cycle overlays all of the other cycles. And explains where the seemingly infinite number of world’s in Everett’s MWI come from.
But that’s just me, thinking another one of those ridiculous ideas that one thinks of when one wanders around outside of the box. But as I’ve said before, I like it out here.
