Discrete symmetries:<br />
The CPT-theorem<br />
Charge conjugation, parity, time reversal<br />
Despite of CP violation, up to now, no violation of<br />
the comb<strong>in</strong>ed version of all three discrete symmetries<br />
has been found. So CPT seems to be a true<br />
symmetry of the world.<br />
Ultimately, this allows for causal structures of the<br />
theory as realised up to now.
