The Purely Geometric Part of “Dark Matter”– A Fresh Playground for “String Theory”

摘要

We argue that part of “dark matter” is not made of matter, but of the singularworld-surfaces in the solutions of Einstein’s vacuum field equation Gμν = 0. Their EinsteinHilbert action governs also their quantum fluctuations. It coincides with the action of closedbosonic “strings” in four spacetime dimensions, which appear here in a new physical context.Thus, part of dark matter is of a purely geometric nature, and its quantum physics is governedby the same string theory, whose massless spin-2 particles interact like the quanta of Einstein’stheory.
