We will in this paper demonstrate that there is a link between cosmology and the Planck scale. It has in recent years been shown that the Planck length can be found totally independent on \(G\), \(\hbar\) and \(c\) and that a series of cosmological predictions can be predicted only from two constants, namely the Planck length and the speed of gravity. The speed of gravity can be easily found without knowledge of the speed of light. This gives a new perspective on cosmology and shows there is a link between the Planck scale and cosmology. This is fully consistent with a recent quantization of general relativity theory that links general relativity to the Compton frequency and the Planck scale. We look at both the Friedmann cosmology and the recently introduced cosmology based on the extremal solution of the Reissner-Nordstrom, Kerr and Kerr-Newman metric.
