Physics, Astronomy & Cosmology / Re: What does it mean that physics is time - CPT symmetric?

The problem of CPT symmetry in particle physics arises mainly due to an error in thinking that all electric charges are the same with the exception of their sign. The charge of the electron and the charge of the proton are not exactly the same. The minimal distances of interaction are different so the potential are the same at long distance but not at the minimum. But when you consider this, it is at the scale of the universe that there is an asymmetry. There is the same quantity of protons and electrons, but almost no positron and no constituent of the antiproton. The total potential doesn't seem to be equal to zero...
CPT symmetry is about conservation. If you suppose no creation, but conservation. There must be a complement somewhere.
What is dark matter? Why does the universe expand... Why gravity is so weak? The complement does not interact with the electric charge of matter, only at the beginning and at the end of the process, where CPT is conserved.
Time CPT symmetry is either space or time.
