    "abstract": "We start from the author\u0027s metric for a rotating and accelerating Universe\nand we calculate the force acting on a particle in it. This force consists of\ntwo parts: one is derived from a potential, and the other describes a Coriolis\nforce coming from the overall rotation of the Universe. We then write down the\nequations of motion, and we solve them analytically in the Newtonian\napproximation. The result has to describe in particular a spiral arm. It gives\nright a logarithmic helix, as it has been found empirically to be the case for\nour Galaxy (in particular).",
