How to Detect Extra Dimensions

The video explores the discovery of gravitational waves and their implications for understanding the universe. It discusses the GW170817 event, where neutron stars merged, providing insights into spacetime dimensions. The video examines the concept of extra dimensions and their potential to explain phenomena like dark energy. It also covers branes in string theory and how gravitational waves can test these theories. Ultimately, the findings suggest no extra dimensions, reinforcing the current understanding of 3-plus-1-dimensional spacetime.
