Discussion Overview

The discussion revolves around the concept of negative dimensions, specifically the idea of -1D, -2D, and -3D as proposed by a participant. The scope includes theoretical exploration of dimensions and their implications in understanding objects and their existence.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant theorizes that negative dimensions could exist as non-existent forms created by the presence of positive dimensional objects, suggesting that -1D could be represented by a blank line surrounded by existing lines.
  • Another participant challenges the validity of the concept by stating that the phrase "it doesn't exist" summarizes the idea, implying skepticism about the usefulness of the theory.
  • A different viewpoint suggests that dimensions are merely a means to describe objects and that any new dimensions proposed must enhance understanding, questioning how the original theory would explain real-world events.

Areas of Agreement / Disagreement

Participants express disagreement regarding the validity and usefulness of the proposed concept of negative dimensions, with some questioning its theoretical foundation and others providing alternative perspectives on the nature of dimensions.

Contextual Notes

The discussion is limited by the guidelines of the forum, which discourage personal theories and non-mainstream speculation, leading to a lock on the thread.

I've been reading all about dimensions and started theorising myself , can there be something like -1D? The theory I came up is this:

The Minus Dimensions don't have an object (it doesn't exist), but it's form is created by the location, which is other specific positive D objects. For example: -1D - A blank line surrounded by other lines which exist. -2D - A non-existant form of a 2D square created by other 2D squares, which exist. -3D - A non existent 3D object surrounded by other 3D objects. The most important rule is that the non-existant object must be the center of the created location.

Basicly this would explain a lot of other events.

Tell me what you think

(it doesn't exist) about sums it up.
 
Objects (and things like force and momentum) exist and are what they are.

Dimensions just provide a way to describe objects (and other things). Any dimensions necessary and useful to describe the real world can be created by the person doing the explaining - provided they're understandable and actually make the description better.

So your idea wouldn't be a theory; it would be a method. It isn't totally clear how your method would explain other events, though. (Don't fall in love with unique methods that just don't add much to what you're trying to say or acocmplish.)
