Only the ones where Rick is the smartest being alive.

That's just what they want you to think.

The idea that a simple choice causes an entirely new universe, with all of the attendant energy requirements of its creation, to spontaneously be created has always seemed laughable to me.

The idea that more than one "universe" could have been created out of the same event, each having their own  separate and distinct dimensions, does not.

Unless you insist that it be like the Star Trek mirror universe, where every individual's opposite exists despite the radically different history each would have and the unlikelihood that all of the exact same pair bondings and offspring would exist.

"Infinite universes" only exist as statistical probabilities of specific quantum outcomes. All of those probabilities converge at the "now," when quantum events occur and cause all of those probabilities to collapse into a stable singular continuity that we call "the past."

It's the rope metaphor: the past is an indestructible rope woven from an infinite number of fibers that all weave together at the "now."

The granddaughter made a good point the other evening. She said the only way travel between the future and the past, sci-fi style, is possible is in a universe where fate is predetermined and immutable. Otherwise there would be an infinite number of alternate timelines (in both directions) making it impossible for a time traveler to ever find their way back to their genuine original point of origin.

Although "multiverses" make for some fun storytelling.

Speaking of sci-fi, you post reminded me of this:

It's kind of a waste of time to go through all the utterly unverifiable theories about the universe, and try to guess probabilities about whether they're true. We'll start making more progress when we embrace the idea that none of us have any farking clue, and more of us start exploring those things that are possible to verify.

Does it matter? Everything is coincidence.  Unless it's a defendant claiming it's a coincidence.
Or
Too small of sampling.
Or
anecdotal.
