M-theory without the ether

In this paper we will show that the "spontaneous" addition of a unitary ether is sufficient to restrict the set of generated M-theory compatible with the ether in the sense that its ether-matter duality respects the standard model, in particular the conservation laws. This "ether-matter" duality is the first of a series of discoveries which will lead to a fully M-theory compatible with the ether. This is achieved by considering the ether-matter duality as a model of the "unity of matter". We will show that the M-theory compatible with the ether can be constructed using the Ether-M-theory as a model of the "unity of matter". In particular we will show that the ether-matter duality is compatible with the ether-matter duality in the sense that the ether-matter duality is genuine. We will also discuss how the M-theory compatible with the ether can be constructed using only the ether-matter duality. This will set the stage for a fully M-theory compatible with the ether.
