During the inflation, to eliminate turbulences in the created spacetime, there appeared the four-fermion/quadrupole symmetry. It caused that the two-component spacetime (the non-gravitating Higgs field plus luminal Einstein spacetime) is globally perfectly symmetrical. Here we described physical meaning of the fundamental symmetries. The CPT symmetry is incomplete so wrongly understood. Symmetry-breaking is characteristic for the components of the quadrupoles because of their internal helicity. The matter-antimatter asymmetry is due to the fourth phase transition of the Higgs field, not due to a CPT-symmetry violation. Here, applying the Scale-Symmetric Theory, we calculated the decay-rate asymmetry for decays of the kaon-long (0.003346) and B mesons (0.7126). These results are close to experimental data. The C, P and T violations follow from the fact that inside the bare fermions there is a torus with internal helicity and that such tori (and loops) produce the weak half-jets in the two-component spacetime and fields. The half-jets are very weak so the asymmetry is very small as well. Due to these half-jets, there appears an asymmetry between parallel and antiparallel orientation of spin and velocity of fermions and their antiparticles (there is more fermions with parallel orientation and more antifermions with antiparallel orientation). But there is the second reason of asymmetries: simultaneously with creation of the dark matter (it can have a residual left-handed internal helicity) there appeared in our Universe the additional electron-antineutrinos that have the left-handed internal helicity so symmetry of the Einstein spacetime inside the Universe is not perfect. We as well motivate why the nuclear strong interactions are CP-invariant.
