A Two-Dimensional Universe

  1. Aug 11, 2006 #1
    This is a model that describes a universe comprised entirely of points (0-dimensional objects) and time. The underlying mechanism of this model is very simple: any object is a collection of point-time constructions. A construction of a higher order can be accomplished through a kind of 'time exposure' of an object of a lower order.

    Let me illustrate:

    Think of one of the tail lights in this picture as our 0-dimensional point. When time is added, this becomes a one-dimensional line.

    Likewise, when a line is exposed to time its time exposure creates a rectangle.

    And a rectangle creates a rectangular solid in time exposure.

    A shape can therefore be thought of as a cross-section exposed to time.

    Illustration (time exposure is from left to right)

    Note that, while a cube in our perception is the very unit of substance and form, it is nothing more than a point and some time in this model.

    When you mentioned a "two-dimensional universe" I was guessing at first that it only included spatial dimensions and not time. I personally don't believe dimensions exist in nature but is only a fabrication of geometry. Singularities gives us good intuition of this.
    There was a book that I think was written in the 19th century called "Flatlanders" It tells of a story of beings living in a 2 dimensional spatial universe when a three dimensional sphere passes through their plane of existence.
    I coudn't find it on Google and the only reference to it was made in a book review of the book, "The Elegant Universe" which is probably where I heard about "Flatlanders". The book is probably out of print and cannot be ontained used due to its age but I would imagine that some university libraries have it in stock

    What's your point? Looks like an oversimplified model that might be used say to illustrate some simple point in relativity but I don't see why it is in philosophy section.
