How Does CMB Polarization Reveal the Universe’s First Moments?

September 20, 2026 | Polarization | Earnest S. Carroll

CMB polarization, first detected in 2002, offers a unique window into the earliest moments of the universe. By analyzing the patterns of polarized light from the cosmic microwave background, cosmologists can test theories of inflation, probe the physics of the primordial plasma, and trace the evolution of cosmic structure.

What Is CMB Polarization? The Cosmic Microwave Background’s Hidden Signal

August 14, 2026 | Polarization | Earnest S. Carroll

CMB polarization is a subtle pattern in the cosmic microwave background that encodes information about the early universe, from the physics of recombination to the possible imprint of gravitational waves from inflation. This article explains its origin, what it reveals, and how it fits into the broader story of cosmic evolution.
