Thinking Beyond: Are there unknowables in physics?

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.
