TL;DR

This paper proposes a novel explanation for dark energy using vorticity-induced negative radiation, challenging traditional cosmological models and suggesting new solutions without requiring modifications to gravity or exotic matter.

Contribution

It introduces a new dynamic model where vorticity generates negative radiation, providing an alternative explanation for accelerated expansion without cosmological constants or exotic matter.

Findings

Vorticity can produce negative radiation equations of state.

Exact dynamic and steady solutions are derived.

The model dismisses the need for cosmological constant or modified gravity.

Abstract

The averaged term of squared vorticity is attributed to accelerated expansion. Cosmological singularity has been a consequence of excessive symmetry of flow, such as "Hubble's law". More realistic one is suggested. Exact dynamic and steady/static solutions are presented. A "negative radiation" equation of state is generated by vorticity which is the dynamic carrier of the dark energy. This fact dismisses the need in 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.
