# A Two-Dimensional Universe

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 http://img60.imageshack.us/img60/1807/1ld2.jpg [Broken].

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.

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
