Earth, portals, parallel universes

A new hypothesis of a structure of the Multiverse which is based on the theoretically and experimentally established assumptionthe existence of hidden extra dimensions in our Universeis suggested. The suggested hypothesis of the Multiverse, contrary to earlier hypotheses of the Multiverse which were mostly developing the principles of the string theory and many-world interpretation of quantum mechanics, ensues from principle to physical reality of imaginary and complex numbers. Therefore such Multiverse allows for its experimental verification and, most likely, really exists. The parallel Universes entering into it according to a principle of similarity of the Universes are governed by the same laws of physics, in they there are elementary particles, atoms and molecules, there are planets and stars, and even there are reasonable inhabitants who, possibly, already found ways of visit of Earth. Therefore inhabitants of Earth also can visit the adjacent parallel Universes through natural and artificial portals.
