What is Reality, What Fantasy?To a mathematician, the point may be a dimensionless object in 3D space, a mathematical object with an x, y, z coordinate in Euclidean space. A line would be a collection of such dimensionless points lined up all in a row. But that is in the world of the mathematician. In the real world, there can be no such thing.
Rather, in the real world, a discrete point, in size, would have to be represented by the smallest subatomic particle that exists and nothing smaller. It has to have real dimensions. Yet, it must be considered to have, at least in some sense, no dimensions at all.
Discrete Mathematics, Discrete Time?A logical question arising from this discussion is: would it be possible to invent a mathematical system based on the assumptions delineated within this article? Would there be a form of mathematics that would enable calculations, and all the other actions one needs to be accomplished in such a discrete system? Indeed, does any of this discussion make sense?
Some will say, No! It makes no sense. But wait a minute. If it does make sense and if it is true, then the time it takes to travel at the speed of light across the diameter of a point is the minimum unit of time, as well. This would mean both distance and time are (for all practical purposes) quantized, would it not?
Of course, we are speaking discretely.
