Quantum Entanglement on Cosmological Scale
  It has been suggested that relational logic, a form of logic developed by C. S. Peirce, is the common inner syntax of quantum mechanics and string theory. A relation may be represented by a spinor and the Cartan-Penrose connection of spinor to geometry, allows to abstract geometry from a calculus of relations-spinors, reviving Wheeler\textquoteright{}s pregeometry. With a single spinor related to the null cone of Minkowski space-time, we search for the geometry emerging when we entangle a left-handed spinor and a right-handed spinor. We find that the quantum entanglement generates an extra dimension and the distance in the extra dimension is measured by the amount of entanglement. The emerging geometry corresponds to a Milne space-time, with two branes coexisting in the extra dimension. One brane hosts left-handed particles (our brane), while the other brane hosts right-handed particles. A distinct phenomenology accompanies our proposal. During the brane collision all points are causally connected, making less pressing the inflationary scenario. The left-right symmetry is achieved with having two "mirror" branes and the neutrino appears as the ideal mediator between the branes. We may revisit also the dark matter, dark energy issues, with everything on the other brane and in the bulk appearing "dark" to us. If biohomochirality is due to parity violation, we anticipate that the life-forms in the other brane demonstrate opposite chiralities. Our scheme brings closer logic - quantum theory - string theory -- geometry -- cosmology, while space-time, rather than an abstract and a apriori construction, appears as the outcome of a quantum logical act.
