The rotating and accelerating Universe

Authors: Evangelos Chaliasos

Comments: This paper is based on earlier work, done during 1992-1994

An attempt is made to explain the spiral structure of spiral galaxies through a possible rotation of the Universe. To this end, we write down a possible form of the metric, and we calculate the necessary quantities (Rik, Tik, ...) in order to form the Einstein equations. We find the two Einstein equations pertaining to the Robertson-Walker metric and no rotation at all in this way. There are introduced then two suitable rotational motions in the universe, and we try to generalize again the Robertson-Walker metric in this way. The result is again null, since it is found that the corresponding angular velocities must vanish. A third attempt is finally done, without restricting ourselves to generalize any existing cosmological model. We introduce again two suitable rotational motions, and we form the appropriate Einstein equations. After solving them, we find that one of the rotations is a usual rotation, while, completely unexpectedly, the other one is interpreted as an acceleration. This acceleration may explain the lately observationally discovered acceleration of the Universe (1998) without a cosmological constant or the ambiguous dark energy.
