SUMMARY

The discussion centers on the naming conventions and hypotheses surrounding the 11 dimensions in string theory. It establishes that higher dimensions do not have specific names and that in string theory, the dimensionality can vary, with M-theory proposing 11 dimensions. The conversation also touches on the implications of the universe's shape, specifically the dodecahedron hypothesis, and its potential effects on dimensional theories. Key contributors to the discussion include Jeebus, Spaz, and references to Charles H. Hinton's terminology for the fifth dimension.

PREREQUISITES
  • Understanding of string theory and M-theory
  • Familiarity with the concept of dimensions in physics
  • Knowledge of Minkowski space and its implications
  • Basic grasp of gravitational theories and their relation to higher dimensions
NEXT STEPS
  • Research the implications of M-theory and its 11 dimensions
  • Explore the terminology used in higher-dimensional physics, including terms like "ana" and "kata"
  • Investigate the relationship between gravity and higher dimensions in string theory
  • Study the Kaluza-Klein theory and its implications for compactified dimensions
USEFUL FOR

Physicists, cosmologists, and students of theoretical physics interested in advanced concepts of dimensionality and string theory.

How do you know it is space like?

That's the way the physics comes out. Physicists are not going to assume more than one time dimension until they see some real reason to do so. There hasn't been any so far. So all their theories follow the relativistic model: one time dimension and the rest spacelike.

I mean how do you know the physics represent space. Could they be representing something that just has the properties of space?

Doesn't matter if it's "space" or something "just like space". What matters is what the equations say, and they can't tell the difference. You have the same thing in general relativity, with "curved spacetime". Is spacetime a thing? That it can be curved? Or do we just mean that geometry varies from point to point?

Maybe i should refine my question.. What kind of form does this space take and could you compare it to anything in form that can be seen by us.
