| Video Discription | It has been 90 years since the concept of dark matter was introduced in astronomy. It lies at the heart of the most successful cosmology model, the LCDM model. However, even after a century, astronomers struggle to know the true nature of dark matter. Even the Standard Model of particle physics is silent about it. Several experiments on dark matter have returned empty-handed. This raises a critical question: What if there's no dark matter? What if there's a fundamental flaw in our understanding of gravity itself? Some physicists are trying to develop a new theory of gravity that explains galaxy rotation curves without needing dark matter. And the latest study shows that one such modified theory called AQUAL can explain galaxy rotation curves better than the LCDM model. The 47th episode of the Sunday Discovery Series explains the discovery and the paper in detail.
