Summary Initially dark matter appeared to be a nice neat theory to explain certain phenomenon of light and stars and galaxies where there was not enough mater to to explain their behavior. But as cosmologists looked further they found other behaviors that dark matter couldn't explain but an alternative theory, modified gravity, handles well. Unfortunately modified gravity has trouble with some behavior that dark matter explains. So which theory is best. Dr. Hossenfelder believes we need to embrace both and work toward combining them into a unified theory.
