A Day In The Half Life
This podcast series chronicles the incredible and often unexpected ways that science evolves over time, as told by the researchers who led it into its current state and those who are going to bring it into the future.
Episode two: dark energy
Twenty years ago, scientists were surprised to discover that the universe’s expansion is accelerating. The unknown and invisible force causing this acceleration was named “dark energy,” and in the years since, researchers learned more about what the phenomenon is not — but have yet to crack the puzzle of what it actually is.
In this episode, we speak with Nobel Laureate Saul Perlmutter (the co-discoverer of dark energy) and rising astrophysics instrumentation scientist Claire Poppett about what we know so far, and how new technology could finally shed (metaphorical) light on this fundamental mystery.

Physicist Saul Perlmutter is a UC Berkeley professor and Berkeley Lab senior scientist. He leads the Supernova Cosmology Project, the Berkeley Institute for Data Science, and the Berkeley Center for Cosmological Physics. He shared the 2011 Nobel prize in physics for the discovery of the accelerating expansion of the universe.
Claire Poppett is the Lead Fiber Scientist for the Dark Energy Spectroscopic Instrument (DESI), a collaborative project led by Berkeley Lab, and an Assistant Research Physicist in the Space Sciences Laboratory of UC Berkeley.
