I was watching this video of an informal explanation/interprentation of string theory, and while it is not as sophisticated or accurate as a formal description of it, but it is appealing to those who want to get an idea about what things are discussed.
I understood both all dimensions and the term metaphor of folding a dimension, with the folded newspaper which made one appear from one point to another in the dimension below. To say that all this actually exists is an assumption, and nothing we can prove for a fact. It might not be the answer to the question "What is there?", however it is certainly the answer to another question, "What could be there?", what is possible to imagine that it could be there. In short, it describes our mental imaginative hard limit. (the soft limit is much lower)
My question is, does it answer "What could be there?", like I presupposed, or "What could be imagined by humans?"?
In other words, does human imagination have barriers? Is there something that can't be imagined by humans? If there is, is it understood by other beings, possible or not, possible in the human mental realm or not? If not, what teriffying feeling it is to realize we were in a cage all along! The bounds of our imagination.
That which I said to be our mental barrier, is not necessarily what it claims to be, "infinity". By this scheme, anything that a human imagines actually exists, because it is part of infinity, which we assumed to exist (by accepting that video)
However, all universes described are logical; they have universal constants and starting state and a timeline tree, which describes all possible endings of the universe and all paths leading to them. It is assumed, in other words, that all these universes are explained by physics. (obviously the physics in a universe with an earth with half the gravity, would be quite different, least to say about its inhabitats and evolution thereof)
What about the illogical universes that are possible to imagine? Here's one, but first I must describe what I mean of a photograph of a universe. A 'photograph' of a universe would describe everything in a universe at an exact moment. It probably has another name, but that's how I'll it. So, in that universe of mine, every photograph would be completely random and not connected with the previous or the next photograph. It's an illogical universe because it can't be described logically.
If I can imagine it, it must exist. However, it is not part of the infinity the video speaks of.
> In other words, does human imagination have barriers? Is there something that can't be imagined by humans?
What's the largest quantity you can picture in your mind?
Can you imagine a thousand bowling pins, or will you just think of a pile of them?
How about one-hundred doves? Can you think of just twenty-five coins, or will you think of five sets of five coins?
At what point does a group of objects become just an abstract number?
I believe starting with basic ideas like this is the best way to understand your/our mental limits.
> If there is, is it understood by other beings, possible or not, possible in the human mental realm or not?
Science fiction has explored this idea (since fiction is all we have). A good example are the extra-dimensional beings from Slaughterhouse Five that abduct the main (human) character at some point in his life and put him in a Zoo. They try to explain the human's perception of reality to Zoo visitors as being stuck on a rail, always going forward, with blinders on his eyes and his head is restrained so can't look around, etc, etc.
This is very much like Plato's cave in a more literal sense.
We're are as safe and as comfortable as a fish that doesn't know it's wet because it doesn't understand dry until the tide pulls back and it's gasping for breath on the beach, baking in the sun...
...Horrible, horrible freedom.
