The Speed of Light is a Big Problem - Dr. C.S. Unnikrishnan, DemystiCon '25, DemystifySci #356

Filmed at DemystiCon 2025 in Portugal, Dr. C.S. Unnikrishnan, from India's Tata Institute, reveals a very different take on the nature of light. Beyond the noise of headlines and textbooks, the speed of light's measurement isn't proving to be so simple. Drawing on years at the heart of experiments that listen for the universe’s faintest signals, he questions whether the speed of light is truly constant. Here, gravity and clocks intertwine, and relativity itself stands on uncertain ground.

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.
