They aren't physical entities at all, according to what you've said
previously. I would imagine they're best described as abstract entities.

Well, code and data can be the same thing, for example in Lisp. Given
googles of these processors interacting only with their closest neighbours,
as I assume they must if no influences are to travel FTL, then you do have
something at least somewhat analogous to the Game of Life. The next logical
question is what is an elemental computation?

So perhaps you have something like a Turing machine here. A state table and
input/output data. (With the possible proviso that the state table can be

Well, in a normal computer (von Neumann type) on any given clock cycle
there is a processor state, and in a sense that's all there is (there are
also signals on the I/O ports and external patterns of data, such as the
current state of the memory and the hard drive, and any other items that
are connected to the processor, but these are all "latent" in a sense - the
processor is only aware of its own state),

It sounds as though there are no programmes. There are only data states.
Sorry to keep saying this but it does sound like a version of the Game of
Life (although presumably a far more advanced one than Conway imagined).

Presmably all the information involved can be represented digitally? If so,
then it can only take on certain values - a single processor would perhaps
be storing a particular number on a given clock cycle. The limiting case
would be a single bit - which is what happens in the Game of Life. More
likely, if the processors are going to output the universe, they would have
to store larger value, but one of a finite range of values.
I'm not sure I see how the "active evolution" differs from "sequential data
states", given that the computations are synchronised by a universal clock.
