The Sorry State of Dark Matter Alternatives

The video explores the mystery of dark matter, a substance that exerts gravitational effects but remains invisible. Despite decades of research, scientists have yet to fully understand it. Evidence from stars, galaxies, and cosmic microwave background supports its existence. Alternative theories like Modified Newtonian Dynamics (MOND) have been proposed, but they face challenges in explaining certain phenomena. Recent studies show conflicting results about MOND's validity. While the majority of astronomers support dark matter, research continues to explore alternative explanations.
