Multiverses and the Movies

Interesting, as I recall Spock raising an eyebrow. Interesting how movies play out in the various models of the multiverse.

“Models of the multiverse, more than one?” you ask, as you are thinking of the one model used in movies such as Doctor Strange in the Multiverse of Madness and Everything Everywhere All at Once. Encyclopedia Britannica has an excellent video describing 3 model types:

1. Bubble universes, baby black hole universes, with different laws of physics.
2. Multiple dimensions, many more dimensions that allow for multiple 3 dimensional observable universes.
3. Many worlds multiverse based on quantum mechanics. It’s commonly referred to, as parallel universes.

Regarding terminology, let’s define a universe as an observable universe. In the Doctor Strange Marvel movie, a gateway would appear between 2 parallel universes (#2 type multiverse), but only one is observable at a time … yes, except when the gateway opens and 2 are viewable. Anyway, when I write, universe, I refer to one observable universe, no gateway open.

“Are other models used in movies?”

“Yes,” as I hear in mind, and on YouTube, the echo of the quote, “No matter where you go, there you are.” It’s from the movie, The Adventures of Buckaroo Banzai Across the 8th Dimension, released 1984. Buckaroo travels from our 3 dimensional universe into another 3 dimensional universe (model #3). Each, is a universe independent of the other, they are not quantum variations of our universe.

For fun and amusement, following is the calculation to explain why 8 dimensions. Note, the movie takes place in our universe and the alien’s universe.

3 dimensions (length,width,height) + 1 dimension of time = 4 dimensions for one universe
2 universes x 4 dimensions for each universe = 8 dimension

Now, I feel like I’m in the Big Bang Theory TV series describing a multiverse for a comic book series. And, having to defend my model against those that prefer the quantum mechanics model. Fortunately, Sheldon is in String Theory, which has 11 dimensions. He’s on my side.

In the later phase of the movie, Interstellar, the character Joseph Cooper, enters a black hole and enters a 5 dimensional universe of rooms where he is able to communicate with his daughter using gravity to affect objects in her room. Hearing 5 dimensions, model #2 first comes to mind. However, it sounds more like a model #1, a 5 dimensional bubble universe inside a black hole.

Since there is no experimental evidence to support any of the models, as they are models without proof, than one is as true as the other. Or is there proof? I would argue, yes.
