# Accounting for some aspects of dark matter and dark energy via noncommutative geometry

## TL;DR

This paper explores how noncommutative geometry, related to string theory, can explain aspects of dark matter and dark energy, linking mathematical structures to cosmic phenomena.

## Contribution

It demonstrates that noncommutative geometry can account for galaxy rotation curves and the universe's acceleration, providing a novel theoretical connection.

## Key findings

- Noncommutative geometry explains galaxy rotation curves.
- It offers a mathematical basis for cosmic acceleration.
- Links string theory concepts to dark matter and dark energy phenomena.

## Abstract

The purpose of this paper is to seek a connection between noncommutative geometry, an offshoot of string theory, and certain aspects of dark matter and dark energy. The former case is based on a simple mathematical argument showing that the main manifestation of dark matter in connection with flat rotation curves in galaxies and clusters of galaxies is also a consequence of noncommutative geometry. The latter case requires an examination of the local effect of noncommutative geometry and the subsequent extension to the global phenomenon of an accelerating Universe.
