Short Wave: The Mystery Of Dark Energy

In this encore episode and Day 1 of our space-themed week, we explore dark energy.

This mysterious energy makes up almost 70% of our universe and is believed to be the reason the universe is expanding. Yet very, very little is known about it. To figure out what we do know — and what it could tell us about the fate of the universe — we talked to astrophysicist Sarafina Nance. She studies cosmology, a field that looks at the origin and development of the universe.
