The missing matter problem: from the dark matter search to alternative hypotheses

TL;DR

This paper reviews the current status of dark matter research, including experimental searches and alternative hypotheses, highlighting ongoing challenges and potential new directions in understanding this fundamental cosmic component.

Contribution

It provides a comprehensive overview of dark matter search efforts and explores alternative hypotheses, offering insights into unresolved issues and future research avenues.

Findings

Current experimental searches have yet to detect dark matter.

Alternative hypotheses challenge the traditional dark matter paradigm.

The paper identifies key challenges and potential new approaches in dark matter research.

Abstract

Dark matter is among the most important open problems in both astrophysics and particle physics. We review the status of art of dark matter search at theoretical and experimental level discussing also alternative hypotheses.
