Author here. Sorry, I guess I misunderstood that part of the hypothesis. Do you have a source, so I can edit my post and correct it?

if you read "Our Mathematical Universe: My Quest for the Ultimate Nature of Reality" by Max Tegmark, many worlds falls in the bucket of L3 multiverse. What you're describing is a L4 multiverse (see comments below. seems it's L2, not L4. will leave my mistake in, although i'm sure there is a parallel universe where i did not make this mistake)

Whoa, I'm so out of my depth. This is really cool. Thanks for sharing. I didn't know about the multiverse levels!

I'm not sure which Sean Carroll talk you saw, but I think he only mentions the differences between worlds in terms of different "choices"-- and these universal constants don't "choose" to be what they are, right?

This is the video that inspired this project, but I don't think that I'm knowledgeable enough to answer your question with 100% certainty.

The JS equivalent would be for this to use different babel, and node.js versions? Random compatible dependencies based on semver?

That's hilarious. I should have done that.

Level 2 is universes generally like ours but with different physical constants: https://en.wikipedia.org/wiki/Multiverse#Level_II:_Universes.... Level 4 includes all abstract mathematical structures, like a universe embedded in a Game of Life simulation.

It seems you're mixing up MWI with a Max Tegmark Level II multiverse: https://en.wikipedia.org/wiki/Multiverse#Level_II:_Universes.... Tegmark considered MWI a separate idea from that and used the label "Level III" for it.

MWI is just one of multiple multiverse ideas. Most multiverse ideas (like Tegmark's Levels I, II, and IV) are basically what-if ideas without any direct evidence, but MWI specifically happens to be a more-grounded idea based on trying to make sense of what the (well-tested) Schrodinger equation says about reality.

The first part of your description of MWI ("The many-worlds interpretation of quantum mechanics imagines our universe as one node in an infinitely branching tree of universes where every possible quantum outcome exists in its own universe.") is pretty good, if a slight though common simplification (different branches aren't entirely separate, so envisioning it as a tree is only mostly correct; different branches can sum together or cancel each other out if their configurations are identical).

Ah, I think I'm beginning to understand. Perhaps I should just remove the sentence about constants changing.

i guess i got it wrong but it's still L2 != L3

It's funny that there is such a pro and anti js movement in the hardcore professional programming world. I know it's a bit off topic. But in every js topic here at hackernews you can feel this tension. I have never seen this before. And this place is visited by the best programmers out there . Very interesting

I don't like a lot of the vitriol, but I do find reading those threads interesting and sometimes really enlightening. Sometimes I disagree, sometimes I agree, sometimes I learn, other times it's just bickering but just the same... it's strange, but interesting.

Pro JS (more TS) camp here.
