hi,
Zee in QFT in nut shell says
"The most unsatisfying feature of field theory is the present formulation of gauge theories. Gauge symmetry does not relate 2 different physical states but the same physical state. We have this strange language with redundancy which we cannot live without"
He also says "We even know how to avoid this redundancy from the start at the price of a discrete space time"
(closing words pg 456)
Does anyone know about the theory of discrete space he is talking about.
Also any comments on Gauge redundancy will be very helpful.
