So what does this diagram even mean?

There's actually a paper that discusses this, if I find it again I'll post it here

Does negative one twelfth equal infinity?

We aren't sure, but it might just be the anthropic principle. Life just couldn't evolve in a universe in a universe with any other amount of dimensions, so of course we live in a 1 3 universe.

Three spatial, one temporal. Although you can define "dimension" more loosely as any attribute you feel like and then there's no limit to how many dimensions the idea you're dealing with can be modeled in terms of e.g. you might make a customer segmentation model for work with 100 dimensions and you could use a generalized version of how distance is calculated in 3 dimensional space to come up with "distance" in the sense of attribute similarity for your 100 dimension situation.

>black hole of higher dimensions
Wouldn't work.
>>As was pointed out by Ehrenfest back in 1917, neither classical atoms nor planetary orbits can be stable in a space with n > 3, and traditional quantum atoms cannot be stable either. These properties are related to the fact that the fundamental Green’s function of the Poisson equation ∇2φ = ρ, which gives the electrostatic/gravitational potential of a point particle, is r2−n for n > 2. Thus, the inverse-square law of electrostatics and gravity becomes an inverse-cube law if n = 4, etc. When n > 3, the two-body problem no longer has any stable orbits as solutions.

>exactly the same

Sorry, I was off by one dimension regarding instability, but the point remains. As only tachyons can exist in this structure, we would not exist.
