    Is time travel Possible?

    Is time travel Possible?

    Will we ever get to rewind time, or fast forward through it? Sanden stops by to tell us all about how time works. He also has a couple ideas about how we might make time travel a reality! But one tricky thing about time travel is that it’s full of paradoxes — so we look into those, too. And science fiction expert Lisa Yaszek swings by to tell us just how long humans have been thinking about time travel (hint: a really long time).



    Listen closely for the mystery sound, and the moment of um: how do clothes get dirty even though you can’t see it?

    Why are smartphones so hard to put down?

    Why are smartphones so hard to put down?

    Screens are everywhere these days! We’re taking a look at why smartphones are so addictive, and how our devices affect us. Our co-hosts took on a bold challenge for this episode: they went a week without phones or tablets. We’ll hear how their experiment went, then Sanden will fill us in on the brain chemical that trains us to love our screens. We'll also learn why the predictability of messages and alerts on smartphones makes them extra hard to put down. Plus, we’ll get a few tips from Catherine Price, the author of How to Break Up With Your Phone. And! A our Moment of Um answers: why are bruises blue, and how do we get them?

    What did dinosaurs sound like?

    What did dinosaurs sound like?

    Did dinosaurs roar? Or meow? And how do we know? Paleontologist Julia Clarke stops by to talk about sounds T-Rex might’ve made. We know a bit more about other dino sounds, and dinosaur expert Riley Black fills us in on those. Plus, a game about dinosaur names, and a look at how dinos might’ve moved with paleontologist Jingmai O’Connor.

    Stick around for the mystery sound, and a Moment of Um that answers this head-scratcher: How does hair dye work?

    Dino Edition: How do we know what dinosaurs looked like?

    Dino Edition: How do we know what dinosaurs looked like?

    20 years ago, we pictured dinosaurs as green, scaly animals. But times have changed! Now, we know some dinosaurs had feathers. And who knows — maybe some even had stripes.



    This episode looks at how we figure out what color dinosaurs might’ve been. We talk to Jingmai O’Connor, who studies fossil reptiles, about finding color pigment in fossils. And paleoartist Emily Willoughby talks to a “museum” about how her dino-depictions have changed over the years. 



    Our co-host, Elyana, also brought us this important question: If dinosaurs evolved from birds and birds don’t fart, did dinosaurs fart? Wha-wha-what!?! Look no further than this episode for an extensive investigation.



    Remember to keep your ears open for the brand new Mystery Sound. And break out your kilns, because today’s Moment of Um answers this question: How do you make clay for pottery?



    There’s so much dino-tastic information that we decided to make a second dinosaur episode. So if you haven’t had enough (and who has?), make sure to check out next week’s show about what dinosaurs might have sounded like.
