In this special crossover episode, Science Quickly shares an appearance by host Rachel Feltman on Vox’s Unexplainable. Together with host Noam Hassenfeld, she explores Scientific American’s special issue on impossible questions, diving into some of science’s biggest mysteries, from how common medications can work without scientists fully understanding them to whether there’s a limit to what humans can ever know. The conversation also ventures to the edge of cosmology, examining competing theories about what may have come before the big bang and why some questions might remain forever unanswered.

  • Hey listeners, it's Rachel.

  • Today's episode is something a little different.

  • We're sharing an episode of Vox's podcast, Unexplainable.

  • In it, I chat with host Noam Hasenfeld about the latest issue of Scientific American,

  • which is all about scientific questions that once seemed impossible to answer,

  • and even some mysteries that we still don't know how to solve.

  • It's a really fun conversation, and I'm super excited to share it with you.

  • We'll be back with a new episode of Science Quickly on Friday,

  • and you'll see part two of this collaboration with Vox in our feed later this month.

  • Without further ado, here's Unexplainable.

  • Rachel Feltman.

  • Hi.

  • Welcome to the show.

  • Thank you.

  • So you host Scientific American's podcast, Science Quickly.

  • Yeah.

  • And I wanted to talk to you because Scientific American has this special issue out called Impossible Questions.

  • It's out in print.

  • It's out online as of yesterday.

  • When I found out about it, it was like someone put the bat signal up in the sky.
