that CPT symmetry is an immediate consequence of T symmetry
If so, then how can T symmetry hold? You seem to be saying that T symmetry implies CPT symmetry. But we know from experiment that CP symmetry is broken. If T symmetry holds, and CP symmetry does not hold, then CPT symmetry cannot hold.
Really, this looks pretty straightforward. The theory you quote has A->B. Experiment !B. Consequently, either !A or !(A->B).
Charge and Parity are likely to be implemented using internal rotation or sequences
Why do you think so?
We don't have to manually reverse particle momenta or spin if we are running things backwards.
Particle momenta, no; spin, yes. Although spin is angular momentum, it does not come about because particles are rotating about an internal axis, as you seem to have in mind. (To the best of anyone's knowledge, of course.) Consequently parity does not auto-reverse under time-reversal.

OK - so, you don't understand the idea. There is a much more detailed description of the associated model written by someone else h...

Hey guys, my quantum physics is not powerful enough to understand this guy... Can anyone help me out with this one?
Thanks LW
