The physics and identity of dark matter

Abstract

This paper follows "The physics and identity of Dark Energy", which is the acceleration energy of old photons. The present paper considers everything else in the decay of our universe; it is an ensemble called "old protons, etc."; the ensemble will be listed. The accelerated expansion of our universe brings the decay debris into the inter-universal medium (IUM) of the multiverse, where it is conserved during long times. Debris clouds eventually accrete from the IUM and grow into proto-universes. The protons, etc. are involved as much as are the photons; they are the receivers of the kinetic energy of photon acceleration. Dark matter is therefore the matter of "old protons,etc." mentioned before.
