Hey Jesse,

So, if this is all true, then there would be much "empty" space in
certain frames of reference and less "empty" space in others. Not
everyone measures the amount of gas in their car by tenths of a
gallon. In fact, most of the world doesn't even know what a gallon
is! Every frame of reference you make will have to be stated before
any work is done on the problem. Still then, many people might not
understand your frame of reference! 
 
Sometimes the simpler theory is more "correct" because it makes
sense. I certainly am not a believer of Euclid's arealess point, but
it does have it's merits. People once thought that the Earth was the
center of the Universe. Aristotle made all kinds of rules to support
his theory in respect to the "strange" orbits of Jupiter's satellites
and moons. But Copernicus's idea of the Heliocentric galaxy
(although not widely accepted at first) was simpler and makes more
sense.
 
I am not doubting the accuracy for your circular geometry. It seems it
will make sense once certain things are worked out.
 
[You then continue, answering my first question]
>As for the space between points, the answer is that this is
>mathematical space that can be referenced in relation to Points on
>the coordinate system.
 
I still don't understand. All space must contain points right? 
Aren't points supposed to define the space of something? If this is
true then there is space unaccounted for... making an infinite amount
of non-space! If it isn't true then state it. And then explain to
me, please, how space could go from empty to not-empty with a change of
frame of reference.
 
John Conway earlier posed the sujestion that you lay your points on a
hexagonal frame. As the frame of reference decreases, there is always
a model for the arrangement of the points so that there is less empty
space. Would you want to use something like that? Or would that
further confuse the issue?
 
[You continue again]
>I hope this helps. I just read an account of the Euclidean idea that
>points have no area, yet somehow make up a line in a book called >The
Non-Euclidean Revolution by Richard Trudeau. This convinces >me once
again that it is simply paradoxical to say, on the one hand, >that
points have no dimension, and, on the other hand, that a line, >which
has length, is made up of infinitely many of these >dimensionless
points. Mutiplying 0 by infinity still equals 0. As far as I >can see,
this remains an unresolved problem for Euclid's Axiom One >(definition
of point), and I believe that ascribing area to points is the >only
way around it.
 
I am in complete agreement with the failure of Euclidean's arealess
points. I also am in agreement with you that a new type of geometry
should be devised. However, I do not believe it has been completed
yet! Good luck. I really hope you can "fix" what the new geometry of
yours needs!
 
Yours,
