[FOM] Could spacetime be discrete?

[Steven Ericsson Zenith]

I think Richard's point is that the assumption of a minimum length is 
problematic.  Special relativity does in fact say something about the 
micro-world because minimum measure at any degree suggests contiguous 
lengths are absolute not relative (i.e., the ruler in Einstein's thought 
experiments would end up as an absolute length). 

Minimum length for Einstein would have to be a universal relative, not a 
universal constant.

With respect,
Steven
