Dark Matter as a Result of the Multiverse and an Improved Prediction Algorithm for Galaxy Rotation Curves and Cluster Velocity Dispersions

We propose a novel hypothesis for the physical nature and existence of dark matter, derived from Hawking’s cosmology. It retains the standard gravitational field equations, but attributes the additional gravitational contribution to a different projected mass distribution. It does not introduce new physical parameters or concepts nor ad-hoc assumptions about the nature of dark matter that lead to an NFW-halo in galaxies and yet explains the observations. Instead, this article argues it is the effect of a superposition of all 165 possible 3-dimensional universes in 11-dimensional space, of which zero to two dimensions overlap with our universe. The conjectural premise is that nothing that could disturb this superposition exists. This, with the dimensions of strings in String theory and in intersecting brane-worlds concepts, explains why dark matter causes flat rotation curves at large radii in galaxies. To support this, the matter distribution in the disks and bulges, calculated by the SPARC team, and the observed rotation velocities are used. Lelli and Mistele showed that the common way to project dark matter halos around galaxies cannot be valid. An alternative is to model dark matter as an emergent result of the compactified dimensions in String theory and the way gravity from superposed universes acts through them. This as well explains the rapid development of large galaxies in the early universe as reported by Labbé. We propose a prediction method for rotation velocities as accurate as MOND. It shows considerable improvement of the predicted velocity dispersions compared with MOND in galaxy clusters.
