Introducing asymmetry into physics

[Loren Booda]

The arrow of time is a most common example of an overall direction in physics, although Newtonian, relativistic and quantum physics do not derive a preferred symmetry. If chaos also fails here, is there any alternative mathematical description of nature that allows a representation of a universe out of balance?

[selfAdjoint]

If you can find interactions that violate both charge and parity conservation that would do it, because according to the CPT theorem that would mean the direction of time was violated too.

Could the discontinuous "wavefunction collapse" introduce cosmological asymmetry through a relatively asymmetric (or symmetric) observer?
