Is time travel possible?

Brains On! Science podcast for kids

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?
