Consider the thought experiment involving four hypothetical perfectly equidistantly juxtaposed "co-moving" observers[A,B,C,D], with a flash of light eminating from their equidistant center-point[P]:
A_________B
_____P
C_________D
The flash of light obeys what is known as Lorentz invariance, and will reach all observers[A,B,C,D] simultaniously, since they are co-moving and at rest with respect to each other.
If reality is totally discrete then the expanding circle of light that reaches all observers simultaneously has a circumference that consists of discrete Planck units, not a continuous circle described by 2*pi*radius?
How can the circumference be determined experimentally?
