Abstract
Tanmay Vachaspati, joined by Maulik Parikh, explores the limits of knowledge in cosmology and particle physics. The discussion moves from large-scale cosmic structure, the cosmic microwave background and black holes to the Higgs particle, symmetry breaking and magnetic monopoles. These established research landscapes frame questions about what remains unknown and whether some questions could be fundamentally unknowable. This is part of the Beyond Center’s Thinking Beyond series on major questions in science. Speakers: Tanmay Vachaspati and Maulik Parikh, Arizona State University. Organized by the Beyond Center for Fundamental Concepts in Science. Monday 28 September 2026, 18:00 America/Phoenix (Arizona, UTC−07:00). Online via Zoom.
