In this episode of Let’s Talk About That, Anirvan Ghosh speaks with Stanford Professor Aaron Roodman, about some of the deepest mysteries in the universe: dark matter, dark energy, and the architecture of the cosmos.
The conversation begins with a deceptively simple question: what is matter? From there, Aaron walks through the fundamental particles that make up the visible universe before stepping into the far stranger territory of dark matter—an invisible form of mass that shapes galaxies and outweighs ordinary matter by roughly five to one—and dark energy, the mysterious property of space that appears to be driving the accelerating expansion of the universe.
A major focus of the episode is the Vera C. Rubin Observatory, one of the most ambitious scientific instruments ever built. Aaron describes how the Rubin Observatory and its extraordinary LSST camera will map billions of galaxies over a decade, offering an unprecedented window into the visible and invisible structure and evolution of the cosmos (Aaron led the team that built the LSST, largest digital camera ever constructed for astronomy) .
