Is Our Universe's Dimensionality Just an Illusion of Information?

Click For Summary
SUMMARY

The discussion centers on the implications of the Holographic Principle and the Bekenstein Bound as presented in Brian Greene's "Fabric of the Cosmos." It asserts that the maximum entropy and information capacity of any volume of space is determined by its surface area, not its volume. This leads to the conclusion that regardless of the number of dimensions, a volume can be described using one less dimension. The inquiry posed suggests that if the universe has 10 or 11 dimensions, the loss of one dimension could still allow for complete freedom in the dimensions we experience, supporting the idea that dimensionality may be less than what is observed.

PREREQUISITES
  • Understanding of the Holographic Principle
  • Familiarity with the Bekenstein Bound
  • Basic knowledge of entropy in physics
  • Concepts of dimensionality in theoretical physics
NEXT STEPS
  • Research the Holographic Principle in detail
  • Explore the implications of the Bekenstein Bound on black hole physics
  • Study the relationship between entropy and information theory
  • Investigate theories of higher dimensions in string theory
USEFUL FOR

The discussion is beneficial for physicists, cosmologists, and anyone interested in theoretical physics, particularly those exploring the nature of dimensionality and information in the universe.

I've finished reading Brian Greene's "Fabric of the Cosmos" and the last chapter intrigued me.

He talks about how Hawking et al have proven that the maximum entropy inside a black hole is a function of the surface area of the BH, not the volume. This can be expanded to any volume of space, ultimately leading to the conclusion that the maximum entropy of (and thus the maximum information containable within) any volume of space is a function of its surface area.

(Wait for it, there's a question at the end of all this)

This places a constraint on the freedoms with which anything within that volume can be described, which implies a limit on our free will. (I am greatly simplifying.)

Generalizing: no matter how many dimensions a volume has, it can be described using n-1 dimensions (eg. a 4 dimensional space has a 3 dimensional surface area and can only contain as much information as can be described upon its surface).

So, my question:

If our universe turns out to have 10 or 11 dimensions, it would only take the loss of one of them (or equivalent loss, divided up among more than one) to satisfy this constraint. This would leave complete freedom in all dimensions that are experienced by us.

Would it not?

What no takers? Am I, like, the only one who's read about the Holographic Principle and the Universe?
 
Holography and the Bekenstein Bound STRONGLY suggests that spacetime is emergent from computational processes in 2 DIMENSIONS and that the fundamental particle is a bit of information- thus any theory positing 10-11 dimensions must be a result of the degrees of freedom of the computation- not a physically higher dimensional background metric- the computational/information based perspective which yields the holographic principle implies that dimensionality at fundamental levels is LESS than observed [built up from the computational graph] as opposed to the notion of fundamentaly higher dimensions
