  The physical models of a successful unified theory about the Universe must
operate in different phase of matter evolution and different fields of physics.
The attempts to build such wide range theory as a bunch of theories developed
for different fields of physics are not quite successful. The accumulated
knowledge from experiments and observations leads to a conclusion that some of
the adopted postulates in the modern physics are not absolutely fundamental, as
considered so far. A new approach for building of unified model of the Universe
suggests resurrection of the principles of causality and logical understanding
for any kind of physical phenomena. It is successfully applied in a new theory
titled Basic Structures of Matter, which provides fundamentals for a unified
theory about the Universe. The new approach leads to different physical models
for the elementary particles and the atoms and also to a different concept
about the Universe. In the same time the suggested models exhibit the same
interaction energies as obtained by the Quantum mechanics and experiments. The
analysis of the physical phenomena from a new point of view allows deeper
understanding of the relations between the basic physical attributes: mass,
energy, space, time, gravitation and inertia.
