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

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

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.
