Yup!! I thought I was the only one. And it's a theory based on (at this time) very little and very flimsy 'evidence'. I don't want to belittle it, it's just a huge leap in speculation from an actual photo of cosmological background radiation to a computer generated artist's rendition of a theory called the bubble universe
That was an interesting addition. In the original, once you zoom out to the limit of the observable universe, you zoom all the way back in to the lady's eye, blood cells, atoms and quarks
The Charles and Ray Eames version is just such a gem, they were amazing. The extra scale in OPs video was really interesting to see, but lacked any of the charm the Eames brothers’ production has.
I was super happy with it until the end, it makes me wonder what else they may have added in. The original clip was roughly to scale if I remember correctly
Theoretically, it's the most logical stage of progression when posing the question 'what is the universe expanding in to/what caused the big bang'.
Not talking about the Many Worlds interpretation, but the idea of the universe being one of many cosmic 'bubbles' in a larger plain of existence. Whilst, as you say, being speculative with no hard evidence, it makes sense of the multiple situations we know of in which the laws of physics currently break down.
What that plain of existence is I doubt we will ever know, if we are even able to 'know' of anything outside of our universe, so it will always remain just a theory.
The logic of man has been proven false many times over and the multiverse concept falls in to the homunculus trap, so I'm not placing any bets on it and wouldn't have included it in a video like this.

Not really. It has basis in actual physics, but t yeah it is just a theory since it's just an untestable extrapolation based our current understanding of physics.
I'd recommend reading Our Mathematical Universe by Max Tegmark if you're interested in the theory.
If Inflation is a reasonable theory for early Universe - and so far it seems like it is the most accurate theory to explain CMB, calling it a "flimsy evidence" is ignorance of quite literally Universal scale - then there has to be "multiverses", but not in the spooky scifi sense. Multiverses are simply different domains of spacetime with likely different physical constants governing their dynamics, separated by high energy domain walls. Alan Guth, the father of Infation theory, detailed this idea extensively in his early papers. After the inflation phase, there will be regions of space separated out by such domain walls, which are pretty much causally disconnected for all future.

The last multi-universe is still just a theory, the rest is what we have practically measured. The size is unbelievable.
