[en] Fermion-antifermion and T asymmetries of fundamental particle creation mechanism underlining the approach are considered. It is noted that T symmetry may be reconstructed if to undertake the Cayley-Dickson extension (doubling) of the Hamilton algebra with that our Universe is connected and to go over to the Cayley algebra as base structure of whole system = Universe + Anti universe (the latter is characterized by negative energies). We show that with such an extension the fundamental Su(2)-isotopic structure of our Universe is connected
