Hawking’s cosmology logically leads to an observed multiverse. This article argues it a superposition of at least three 3-dimensional universes in a 4-dimensional space, which each have two overlapping dimensions with the observed universe. For there is nothing outside it that could disturb the superposition, it could last forever. This explains why dark matter yields a linear decrease of gravity with distance to visible mass at large radii in galaxies. To prove this, all contributions of visible matter in the disks and bulges, calculated by the SPARC team, have been recalculated to verify the brightness and gas density are correctly interpreted. Lelli and Mistele showed the common way to project dark matter halos around galaxies cannot be valid. Since application of General Relativity would need these halos too, it must be modified with additional terms. Bekenstein’s TeVeS does this. Using TeVeS, a decay of the contribution of dark matter to gravity in galaxies with the expansion of space is confirmed. This explains the rapid development of large galaxies in the early universe that is reported by Labbé. A new prediction method for rotation velocities that works at all radii in galaxies is offered. It is 25% more accurate than MOND and TeVeS.
