Similar to the one Copernicus took when he abandoned the complicated geocentric (Ptolomaean) view „only“ by varying the point of observation from geocentric to heliocentric, hereby gaining a much simpler, aesthetically more satisfying and more “realistic“ picture of the world. Also, the key to the Theory of Relativity was the radical turning away from an established assumption and point of view.“Only” since Einstein had questioned the absolute time of the Newton theory and, instead, had postulated, the velocity of light is a universal constant of nature which also must be subordinate to the flow of time, he overcame the discrepancy between logic and observation, prevailing in the view at that time, and thereby again had acquired a more comprehensive and more realistic view of the world. Must we revise our definition of time again, by linking it  up with cosmic processes which we can observe? In his book “The immortality of time“, Paul Davies remarks in this regard [7], p. 11: “The conventional presentation of the time leaves us helpless to a chaos of mysteries and contradictions.  In my estimation, the Einstein time is not suitable to completely explain our perception of it.” And further [7], p. 18: “Could it be that the  Einstein time and the cosmic time are not identical? Is Einstein’s flexible time simply not flexible enough to reach back to creation?  ”

2. Actual problems of cosmology and elementary particles physics

As the first one, Albert Einstein had dared trying to formulate a field theory which should comprise all phenomena  of our physical reality in a comprehensive theoretical structure. Today, we know [3], p. 53: “ he applied the wrong tactics when trying to link the gravitation to the electro magnetic force (light), instead of to the nuclear force.”
Meanwhile, great efforts have been made to find an all- comprising theory (TOE), by means of mathematical formalisms especially developed for this task. Many theorists thus believe they are, by using the new, rather abstract super string theory
[3], p. 13: ….“probably truly on the track of a unified field theory: a comprehensive mathematical description of the unification of all known forces of the universe."
However, it must be doubted if such a theory, if it was successful, could really answer all unsolved questions of cosmology and elementary particles physics.

2.1  Weaknesses of the big bang theory

On one hand, the big bang theory is convincingly supported by observations ( cosmic background radiation, Hubble’s red shift, frequency of occurrence of chemical elements in the universe), on the other hand, it cannot explain some basic properties of the universe:
- Why was the early universe to such a high degree isotopic? - ( Horizon problem)
- How could galaxies build up from a state of the universe formerly so highly isotropic? - ( Problem of galaxy formation)
- Why is the energy density in the universe just sufficient to span out a plane (Euclidean space? ( Problem of planarity)
- Why do we observe stars which appear to be older than the universe? - ( Problem of world age)
