On New Physical Reality (on Psi--ether)

It is shown that there exists a new physical reality -- the $\Psi$--ether. All the achievements of quantum mechanics and quantum field theory are due to the fact that both the theories include the influence of $\Psi$--ether on the physical processes occurring in the Universe. Physics of the XXth century was first of all the physics of $\Psi$--ether.
