The averaged term of squared vorticity is attributed to accelerated expansion. Cosmological singularity is a consequence of excessive symmetry of flow, such as “Hubble’s law”. More realistic one is suggested. The new cosmological principle is applied to irregularities -they are homogeneous and isotropic in average to some extent within the corresponding Mega-galactic scales. The “Big Bang” is in fact the local bounce of Meta-galaxy which is typical among myriads of other bounces. Exact dynamic and steady/static solutions are presented. A “negative radiation” equation of state p =є/3 with p<0, є_<0 is generated by vorticity which is a dynamic carrier of the dark energy. This fact dismisses the need in a cosmological term, in any modifications of the gravity theory or in an exotic matter. A new concept of a material point is established. The paper comments as well on social and educational aspects of the findings.
