Observer frame rotation rates and magnetic fields in spatially homogeneous universes
We discuss how the rotation of an observer’s Cartesian reference frame is related to the precession of the shear tensor’s principal axes and to the rotation vector of the fluid. An approximate solution of Einstein’s equations illuminates this relationship further. In the case with a magnetic field a...

| description | We discuss how the rotation of an observer’s Cartesian reference frame is related to the precession of the shear tensor’s principal axes and to the rotation vector of the fluid. An approximate solution of Einstein’s equations illuminates this relationship further. In the case with a magnetic field and fluid flow a vorticity is allowed in Bianchi I cosmologies. |
