A Day In The Half Life: Dark Energy

March 10, 2021

In the latest episode of Berkeley Lab's new podcast series A Day In The Half Life, BIDS Faculty Director Saul Perlmutter, a professor in UC Berkeley's department of Physics and a 2011 Nobel Laureate — and the co-discoverer of dark energy — talks with LBL Science Writer Aliyah Kovner and Claire Poppett, the Lead Fiber Scientist for Berkeley Lab's Dark Energy Spectroscopic Instrument (DESI) and an Assistant Research Physicist in UC Berkeley's Space Sciences Laboratory.  

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.  This episode, addresses what is currently known about dark energy, and how new technology is finally shedding (metaphorical) light on this fundamental mystery. 

A Day In The Half Life is a new Berkeley Lab podcast series that 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.
