We live our lives in three dimensions. But we also walk those three dimensions along a fourth dimension: time.  

Our world makes sense thanks to mathematics. Math lets us count our livestock, it lets us navigate our journeys. Mathematics has also proved an uncanny, stunningly accurate guide to what Brian Greene calls “the dark corners of reality.”

  But what happens when math takes us far, far beyond what we — as humans — are equipped to perceive with our senses?  What does it mean when mathematics tells us, in no uncertain terms, that the world exists not in three, not in four — but in no fewer than eleven dimensions?  

In this episode of Orbital Path, Brian Greene, director of Columbia’s Center for Theoretical Physics and a celebrated explainer of how our universe operates, sits down to talk with Dr. Michelle Thaller. Together they dig into the question of how we — as three-dimensional creatures — can come to terms with all those extra dimensions all around us. 

 Orbital Path is produced by David Schulman and edited by Andrea Mustain. Production oversight by John Barth and Genevieve Sponsler. Hosted by Michelle Thaller.
