Ordinary matter is everything familiar to us—stars, planets, people—but about 85% of all matter is actually invisible, neither emitting light nor interacting through almost any known forces of nature. We infer dark matter’s existence only through the profound gravitational influence it exerts on the cosmos. Scientists realized over a century ago that dark matter exists, yet understanding what it is made of and what laws of physics govern it remain among the greatest unsolved puzzles in physics.
Join KITP Postdoctoral Scholar Amalia Madden to explore the compelling evidence for dark matter, discuss why understanding it is essential to uncovering the history of our Universe, and learn how researchers today are designing innovative experiments to reveal its hidden nature.
