Multiverses

sorry in advance for any spelling mistakes 

I dont know if anyone else feels this way but recently ive found myself caring too much about how (theoretically) the multiverse should work to even make a lick of sense if multiverses were as definition; multiple universes. Now ill admit i've done no research on this whatso ever this is all purely my current opinion if anyone can enlighten me then i'll welcome it.

I personally think how the concept is stupid with how it's presented. Dont get me wrong I LOVE this theory and believe that it has a good chance of being real, personally i dont really care about proof of existence or anything i find it fun to just believe as long as you make it make sense, yk?

but notice if you briefly brush over the basic concept of multiverses and infinite realities it makes sense but you delve into the idea of things happening in the space between the universes and stuff technically having their own universes, im aware that doesnt make sense just bare with me. 

If you take Across the Spiderverse for example, if my memory serves correctly i think the spider society and stuff happened all like, outside of prime universes or smth i cant remember exactly where but the point is that thousands of people from different universes are all just, chilling, either in the spaces between dimensions or in a whole other dimension in general. (please correct me if im wrong btw i saw the movie once and that was when it came out) 

since there are INFINITE universes there would technically be a second universe miguel tried helping miles or Pavtir's universe didn't began crumbling due to miles saviing his gfs dad which i know, beats the purpose of a canon event which also made me come to a realisation, or just an idea anyway, infinite universes mean infinite possibilities no matter how small the difference there will always be a universe where that happens, there's a universe out there where your life's exactly the same but you had blueberry pancakes instead of ceral for breakfast today, theres a universe you're literally godzilla, endless possibilities which made me wonder, if universes have infinite possibilities  then theres always going to a universe where someone enters the space between them, which theoretically, could not work if people where always jumping into the space at some point it would have to become obvious that the multiverse is real or whatever, take marvels 'What if?' for example, the watcher (for those who dont know, is literally just a guy who observes universes never allowed to interact although that doesnt completely stop him) if the watcher were to exist in a space surrounded by multipul realities, the spot wouldve been bound to see him im sure the doctor wouldve been bound to know abt him or mention him when dropping rose off to another dimension (im not that far into it sorry) 

but my point is i believe that if the multiverse were to be real it would work like one of those russian doll things

these things

if this gets to confusing think of an onion ig i just dont like onions, basically i think to work the infinite realities would work as layers the first layer/bottom layer (the baby doll) would be where basic seperate universes, like ours, the second layer would be where an infinite amount of universes would be kept, eg. where all the different possibilites of what could happen in across the spiderverse could be i havent thought this far but i think the final or at least second to last if there would be a higher power is where someone like 'the watcher' would lie

anyway if you actually read all this gold star for you thanks for reading the rambles of a mad man and i hope this made some sort of sense
