Good to hear. If you get ambitious you should read Stephen Wolfram's "A
New Kind of Science".

The study of mathematical models based on rules which may be applied to
initial conditions, and particularly, something called "Cellular
Automata" is a good match for your inquirey into discrete space-time.

I'm not prepared to make that statement.

For one, in Quantum ElectroDynamics (which is the best scientific
theory for matter and light ever) the photon has amplitudes that allow
it to travel greater and less than c.

Secondly, a good theory of quantum gravity has not been developed under
the assumption that all fields propogate at c and there are some good
arguments that gravity propogates considerably faster than light:
