The main purpose of this paper is to show and introduce some new interpretative aspects of the concept of “emergent space” as geometric/topological approach in the cosmological field. We will present some possible applications of this theory, among which the possibility of considering a non-orientable wormhole, but mainly we provide a topological interpretation, using this new approach, to M-Theory and String Theory in 10 dimensions. Further, we present some conclusions which this new interpretation suggests, and also some remarks considering a unifying approach between strings and dark matter. The approach shown in the paper considers that reality, as it appears to us, can be the “emerging” part of a more complex hidden structure.

This article shows how string theory is able to model nonphysical particles and how three-dimensional string theory “branes” (parallel universes) could hold dark matter and dark energy. Introspective experience from scientifically oriented groups gives us some clues of how the mind and consciousness could be described. The resulting synthesis from science and direct introspection, for understanding mind and consciousness, are presented. It shows a cosmos with: (1) A parallel nonphysical universe containing dreams, thoughts, emotions, and memories. This universe, called the psychological universe, is probably based on dark matter; (2) A parallel nonphysical universe where intuitive nonphenomenal thinking takes place and where personality and worldview are stored. This universe is called the intuitive universe and is probably based on dark energy and seems to have quantum mechanical qualities. These two universes together make up the mind such as it is defined in this article; and (3) A third nonphysical universe filled with negative energy could make up consciousness. All four universes (including the physical universe) have different vacua, dimensions, and energy levels, so they are all around us but separated. I propose that biological beings consist of a physical body in the physical universe plus entangled bodies in the three nonphysical universes. Entanglement is established by signals going both ways between the different bodies. String theory shows how the interaction between branes/universes can take place. Such a worldview seems to match the requirements from string theory so that it becomes a theory that includes the physical universe and the mind (all kinds of positive energy), and the connection to consciousness. Consciousness itself is based on negative energy, according to mathematician Luigi Fantappiè. The physical base for negative energy is still an open question.

In recent years it has been realized that pre-BBN decays of moduli can be a significant source of dark matter production, giving a "nonthermal WIMP miracle" and substantially reduced fine-tuning in cosmological axion physics. We study moduli masses and sharpen the claim that moduli dominated the pre-BBN universe. We conjecture that in any string theory with stabilized moduli there will be at least one modulus field whose mass is of order (or less than) the gravitino mass. Cosmology then generically requires the gravitino mass not be less than about 30 TeV and the cosmological history of the universe is nonthermal prior to BBN. Stable LSP's produced in these decays can account for the observed dark matter if they are "wino-like." We briefly consider implications for the LHC, rare decays, and dark matter direct detection and point out that these results could prove challenging for models attempting to realize gauge mediation in string theory.

Dark photons and mirror matter are well-motivated dark matter candidates. It is possible that both of them arose during the compactification and symmetry breaking scenario of the heterotic [Formula: see text] string theory and are related to each other. In this case, dark photons can become a natural portal into the mirror world. Unfortunately, the expected magnitude of the induced interactions of ordinary matter with mirror matter is too small to be of phenomenological interest.
