Dark Energy and Dark Matter, Mirror World and E_6 Unification

Understand

In the present talk we have developed a concept of parallel ordinary (O) and mirror (M) worlds.

• We have shown that in the case of a broken mirror parity (MP), the evolutions of fine structure constants in the O- and M-worlds are not identical.
• It is assumed that E_6-unification inspired by superstring theory restores the broken MP at the scale \sim 10^{18} GeV, what unavoidably leads to the different E_6-breakdowns at this scale: E_6 \to SO(10)\times U(1)_Z - in the O-world, and E'_6 \to SU(6)'\times SU(2)'_Z - in the M-world.
• Considering only asymptotically free theories, we have presented the running of all the inverse gauge constants \alpha_i^{-1} in the one-loop approximation.
