that's a really cool theory I can get behind, I love this stuff so thanks for sharing!
Entropy is clearly a rule that needs to exist for some reason, when you think about life in general, it literally IS entropy, the act of something going from low chaos to high chaos is the birth of life itself, what's more chaotic (and chaos making!) than life, we throw rocks in the calm pool of the universe.
I've been pondering reality so long, I'll doubt I'll live long enough to get a confident answer but being from a game dev background you start to notice over time how some of the quirks found in our current games/simulations can be applied to real life phenomena, memory management, concurrency, lazy-loading, level of detail systems etc, if I'm seeing things in our world that somewhat resemble our current attempts to simulate worlds, does that mean we're potentially living in a man-made simulation, maybe even a recursive fractal of simulations within simulations, is our future self our current selfs god?
My current theory is
We co-exist in one simulation, but that simulation is split up into smaller parallel realities, so you can almost think of each reality as a new dimension spanning a thin slice of the other axis, so like our own little reality bubble that follows us around everywhere across time and space. So whilst you and I may be in the same place at the same time, we're both in our own little bubble realities, and our observations may differ.
These bubble realities have a higher fidelity of simulation, and things that "occur" or "exist" outside of them, do not truly occur but are simulated in a fuzzier low fidelity method as and when they are actually needed. So if I miss a live sports game, it's fine, the result isn't really decided until I check it anyway.
The creepy thing is when you start thinking you can see where your bubble ends, all those nameless buildings you pass everyday but pay no interest to, ones you have no reason to interact with, speak about, or even hear about.
One fun little trick is go for a walk but do not decide where you going, just head in a direction, and every time you have to make any sort of decision, do I turn here, do I try looking into that building etc, try to do something as random as possible. The results are usually pretty chaotic, like the simulation is trying to retroactively correct itself.
I went on a random walk (quite literally) and ended up at a pub I've never heard of, despite living here for 10 years, nobody ever mentioned it, never saw it mentioned online, it literally didn't exist, then the day I discover it and get a drink, the next day someone at work asks me about it, the day after that I see a news article about it online dated 2 weeks ago.
Have fun in your little bubble!
