maybe in mathematics, a point can be described as a zero-dimensional "object" because it represents a position on an Argand, or Cartesian plane. But consider the physical world -- it cannot exist, a zero-dimensional point -- because to exist implies having a dimension of some sort (I mean, consider in mathematics you can have raise a number to a negative power, and express it in a + bi form, but there is no naturally occurring number which actually represents this. So you can have non-existant things in maths which never happen in the real world...) Is zero-dimensions singularity? Speaking of singularity, where does the matter and light that enters a black hole go to? One last thing... I actually do understand what you are saying, tank. A two dimensional being in "flatland" would have a single line take up their field of vision, and this line comprises of the many different objects it can see, but depth, as you say, is rendered obsolete because everything looks equally close -- just another segment of the line. That's how I interpret what you are saying. :?
