Discussion Overview

The discussion revolves around the concept of different orders of dimensions, exploring the classification and physical interpretation of dimensions, including time and spatial dimensions, as well as higher dimensions in theoretical frameworks like string theory.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant proposes a classification of dimensions into orders, suggesting that time is 0th order, normal spatial dimensions are 1st order, hyper dimensions are 2nd order, and so on up to higher orders.
  • Another participant questions the physical meaning of dimensions and the conceptual differences between dimension and order, emphasizing the need for clarity before ordering dimensions.
  • A participant references general literature on dimensions, noting that while commonly three spatial dimensions and time are discussed, there are theories like SuperString and SuperGravity that involve 10 and 11 dimensions respectively, suggesting a potential for higher dimensions.
  • There is a reiteration of the need to define what a dimension is, with one participant asserting that a dimension is a measure of something that cannot be formed by combination.
  • One participant expresses disapproval of speculative ideas, indicating a desire for more grounded discussion.

Areas of Agreement / Disagreement

Participants express differing views on the classification and interpretation of dimensions, with no consensus reached on the definitions or orders of dimensions. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Participants highlight the ambiguity in the definitions of dimensions and their orders, as well as the speculative nature of some claims regarding higher dimensions in theoretical physics.

Different orders for different dimensions.

e.g.
time(0D): 0th order
'Normal' spatial dimensions (1D,2D,3D): 1th order.
'Hyper' dimensions: 2nd order.
dimensions up to D15: 3rd order.
D16 up to D-idontknow: 4th order.
etc, etc.


Am I completely wrong?

Before we even begin to talk about dimensions, we must ask the following questions:
what is a dimension physically? What is space physically?

Before we can order dimensions we must be clear as to what exactly we are talking about. Also what is the conceptual difference between dimension and the order of dimension, what is the purpose for ordering the dimension?

General literature speaks about three dimensions and time therefor astating difference nl. space and time (later on put together:spacetime). furthermore if spoken about a hypercube "..it's a cube in the fourth dimension..." actually meant is D5. And up to D9 you can probable visualize mentally.

Nowadays SuperString works with 10 dimensions; not 5 or 6 or 21. And SuperGravity does it with 11; not 10 or 12 or 43. Behold...SS 10 and SG 11...interchangeable. And I feel that we will fine-tune the whole lot with dimensions up to D15.

Probablely dimensions aren't that different from each other, but because we humans seem to get it in chuncks (first three spatial dimensions, then time, then the dimensions for the hyperthingies, etc. etc.) it might be so
that dimensions reveal themselves (or get useful) in portions. Maybe that's why I never heard from the 8-dimensional-string-theory.

And when you want to explain graviton hopping, noninteger branes, bubblebranes and intermitting time you just have to wait another 7 decades or so, we might get 37-dimensional theories.

You still haven't answered the question, what is a dimension? You use the word dimension but do you know what it means?

(A dimension is alone.)

It's a measure of something which can not be formed by combination.
 
Abject speculation is not welcome here.
