Strings, Topological Change and Dark Matter
Abstract
Dark matter, first postulated by Jacobus Kapteyn in 1922 and later by Fritz Zwicky in 1933, has remained an enigma ever since proof of its existence was confirmed in 1970 by Vera Rubin and Kent Ford by plotting the rotation curve for the Andromeda galaxy. Here, some concepts from string theory and topological change in quantum cosmology are used to formulate a new model for dark matter. The density profiles of dark matter halos are often modeled as an approximate solution to the LaneEmden equation. Using the model proposed here for dark matter, coupled with previous work showing that the approximate solution to the LaneEmden equation can be an exact solution of the EinsteinMaxwell equations, provides a new insight into the possible nature of dark matter.
