Erick, (02)
Now I think I understand you, and even why you used the expression
'time/space is physical'. In what is traditionally called the
philosopphy of space and time (which I first thought of), you will
probaly not find anything of interest for you. Here one is concerned
with the nature of the utmost space and time in which everything
spatiotemporal is assumed to exist. But you are (I take it now) looking
for a 'space' or spatial structure that is to cell theory what the
skeleton is to anatomy. In my opinion, such a 'space' is not like the
utmost space a *particular*; it is like properties/qualities and natural
kinds a *universal*. That is, such a 'space' can exist at many
places/regions simultaneously, and it might well be called a
'qualitative space'. Similar remarks can be worked out for 'qualitative
time'. (03)
Perhaps you can benefit from things done under the title 'spatial
reasoning', but I am not in general familiar with these things. Here,
though, you get links to two papers that discuss formal features of the
kind of 'spaces' you seem to be interested in: <

< http://www.acsu.buffalo.edu/~md63/RelPlApOnFin.pdf > (04)
