How will the universe end? That's today's big question, and my guest is Sarafina El-Badry Nance. Sarafina is an NSF graduate research fellow, astrophysics Ph.D. candidate, and Forbes 30 Under 30 Science 2022 honoree, specializing in supernova and cosmology. She's also the author of the new, honest, and empowering memoir "Starstruck: A Memoir of Astrophysics and Finding Light in the Dark".Sarafina and I recorded this conversation back in 2021, and not only is it an all-time listener favorite, well, the universe at large hasn't ended yet, even though it's felt like it was coming sometimes. We've all been through a lot since then, and this conversation is still and will remain, evergreen.Sarafina's goal is to measure the rate of the expansion of the universe as propelled by dark energy. And, I'm sorry if that isn't exciting enough for you, I don't know what to tell you.-----------Have feedback or questions? Tweet us, or send a message to questions@importantnotimportant.comNew here?
