The Controversy of Modified Newtonian Dynamics (MOND): A New Theory challenging Dark Matter Introduction One of the most significant scientific controversies in contemporary astrophysics concerns the nature of dark matter. Dark matter is an enigmatic form of matter that does not interact with light or electromagnetism and, consequently, cannot be detected directly. Although there is overwhelming indirect evidence of its existence from various astronomical observations, its nature and composition remain a mystery. Several theoretical models have been proposed to explain the dark matter phenomenon, with the most popular one being the Cold Dark Matter (CDM) model. However, the CDM model has faced challenges from modified Newtonian dynamics (MOND), a new theory that argues that dark matter does not exist. This article will discuss the controversy of MOND and its potential implications for astrophysics. The Cold Dark Matter Model and Its Challenges The CDM model is the most popular theoreti...
