Well yes, but actually no.

The set of all possible universes does not include impossible universes.

The multiverse either exists or it doesn't. Individual universes have no influence over that.

there is a universe full to the brim with chickens, all that chicken space.

There's a parallel universe in which the fundamental laws of physics are different: the weight of an electron, the gravitational constant, how many fundamental particles there are, the cosmological constant, ...

One night I was thinking about multiverse stuff and I wondered if you could cause a paradox in another timeline. I got stuck on thinking that it might not immediately destroy the timeline and then I began to worry what it would be like if we lived there. (I was not sober lol.)

Group theory already solved that one 😄

Aargh! Okay, I'm going to fix this and the fine tuned universe argument all at once.

Nature does not care about your silly numbers and hypotheses. All of our scientific mechanics are models of the observed universe. The ones we call theories are just models good enough to be usefully predictive as to forecast outcomes, allowing us to safely land airplanes, build bridges, make safe pharmaceuticals (or super addictive ones, if we want), split atoms safely to produce power (or unsafely to level cities) and so on.

We care about the math and the numbers because they give us results that are consistent with nature. But nature is doing what it's doing because it's behaving as a giant causal engine (ever-smaller forces that drive observable phenomena, at least until we get to Planck scale). So when it comes to the fine tuned hypothesis, to quote a Texas physicist whose name I can't remember These numbers ain't for fiddlin'

If there are any storm gods at all, anywhere in the world, to the last, they are content to allow lightning to behave strictly according to static-electricity electrodynamics. And ball lightning happens whether or not we have a model that explains it. (Presently, we don't.)

If one or more of the many-worlds hypotheses are true, no given universe cares what its science-savvy inhabitants have determined and whether their mathematical models allow for models that are factual. Facts don't care about your feelings. Facts don't care about your science either. It's more that the science does is best to describe what's going on in the facts.

Irreducible complexity is solved.

PS: This also stabilizes the cosmic horror scenario of Azathoth's dream, that Azathoth gibbers in the center of the universe dreaming its whole, and each and every one of us is a mere figment, who will vanish to oblivion when eventually he awakes: From what we can observe Azathoth has been dreaming consistently for thirteen billion years, and doesn't seem to be in a hurry to wake up, and his dream is profoundly consistent so that the mathematics we use to send probes from planet to planet, eventually into the outer solar system always works. Azathoth has our back!

Nah but here's the real staggering part. It should be far easier for universes to form locally conscious beings than it is to form all the pieces necessary to naturally evolve conscious beings. These would mostly be very short-lived arrangements of energy with no hope of surviving but certain arrangements would even have false memories, making them believe that they have existed far longer than they actually have.

They may even have false memories of living on earth.

They may even have false memories of your exact life.

And they would be, by far, more common than any form of actual sustainable life. It is vastly more likely that you have experienced this post as a false memory created inside one of these short-lived consciousnesses than for any of this to be real.

There is no such thing called Multiverse
