White holes, primordial black holes and Dark Matter

Abstract: Strange Quark Nuggets are the relics of the microsecond old universe after the big bang. The universe having experienced a mini inflation of 7-e folding has gone through supercooling leading to a first order phase transition from quark to hadrons. Strange Quark Nuggets, the relics of this phase transition will constitute 12.5% or at the most 25% of the dark matter of the universe. Only 10-3 or 10-4 part of the total number of SQNs form binaries, and only some of the binaries will turn to black holes. Primordial Black Hole (PBH) as a relic is shown to be not a plausible scenario. Simultaneous observation of high energy gamma rays from SQN binaries formed from coalescence of SQNs along with black holes will be the vital cursor of this evolutionary scenario just presented.
