Inside the Shadow World of Dark Matter

April 9, 2025 | 3:30 PM EST | Online

What if the universe's hidden mass is more complex than we thought?

Dark matter could be an entire dark sector of the universe, with its own particles and forces. Hear from physicist Kathryn Zurek, who proposed the dark sector theory, how this shadow world might operate, and how researchers are designing new types of experiments to search for it. Read about how Dark Matter Might Lurk in Its Own Shadow World.
