# Strings, Topological Change and Dark Matter

@article{Marsh2019StringsTC, title={Strings, Topological Change and Dark Matter}, author={Gerald E. Marsh}, journal={arXiv: General Physics}, year={2019} }

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 Lane-Emdenโฆย

We generalize the classical action-at-a-distance theory between point particles to include one-dimensionally extended objects (strings) in space-time. We build parametrization-invariant couplingsโฆ

We constrain the physical nature of dark matter using the newly identified massive merging galaxy cluster MACS J0025.4โ1222. As was previously shown by the example of the Bullet Cluster (1E 0657โ56),โฆ

The Wheeler-DeWitt equation is based on the use of canonical quantization rules that may be inconsistent for constrained dynamical systems, such as minisuperspaces subject to Einstein's equations.โฆ

It is shown that a black hole of fixed mass can carry arbitrary axionic charge and it is argued that the existence of axion charge may play a significant role in the late stages of black-hole evaporation.
