What if one of modern cosmology’s greatest triumphs was built on a false story? In this talk from DemystiCon: Beyond the Big Bang, physicist and historian of science Dr. Andre Koch Torres Assis digs deep into the cosmic microwave background (CMB), the so-called “fingerprint” of the Big Bang, and uncovers a history that challenges the dominant narrative. Contrary to popular belief, George Gamow and the Big Bang camp never predicted the CMB’s 2.7K temperature. In fact, their estimates were off by nearly an order of magnitude. Meanwhile, steady-state cosmologists consistently predicted the correct background temperature of space long before the CMB was discovered by Penzias and Wilson. The difference was that instead of searching for the birth of the universe, they were simply calculating the temperature of cold, rocky bodies absorbing and remitting distant starlight. Assis weaves together redshift anomalies, missing histories of radioastronomy, and overlooked insights from pioneers like Finlay Freundlich, Assis shows how a false myth of prediction has been used to cement the Big Bang as fact, rather than leaving open the possibility of the CMB being the signal of an eternal universe, rather than the echo of creation.

When not talking to brilliant people or making movies, she spends her time painting, reading, and guiding backcountry excursions. Shilo also did his PhD at Columbia studying the elastic properties of molecular water. When he's not in the film studio, he's exploring sound in music. They are both freelance professors at various universities.
