Neil Turok has a new
proposal for The symmetric multiverse, with some relation to my Quantum FFF Theory, ( with only CP symmetry
without time reversal)
In my Quantum FFF Model however, the T = Time component is not symmetric because clock are running over there ( in the anti material copy universe) with a left handed rotation opposite to our clocks with right handed rotation.
So the opposite world is CP symmetric including clocks, but not time itself.
