Is our space an object of point rotation?
The interval of a flat Minkowski space is invariant with respect to the previously found three-dimensional transformation for point rotating coordinate systems. The assumption that our space is an object of point rotation at a frequency initiates the appearance of a new term in the Dirac equation... The upper boundary for this frequency is determined from shifts of the degenerate levels of the hydrogen atom. The boundary is about 2.9 kHz. read morePDF Abstract
