That's may be right, production of matter is impossible without antimatter (partner) and existence of many universes at the same time is possible (sons)

Thanks Prof Ali Esmail Al-Snafi for your answer. I think the other members could also join in to create a new trend of thought.

If the universe doesn't necessarily have a spouse or a sibling, it at least has a parent. Successive total states of the universe can be metaphorically conceived as having a parent-to-offspring relationship. Separated or nonadjacent total states of the universe stand in an ancestral relationship just in case they are connected by a finite sequence of total states, each of which is the parent of its successor.
