Janna Levin on Extra Dimensions and How to Overcome Boots in the Face | The Tim Ferriss Show

Janna Levin traces her unlikely path from a reckless teenager who landed in college after a near-fatal car accident to a theoretical physicist drawn in by a philosophy lecture on Einstein. She explains how the universe could be finite without an 'outside,' how extra dimensions allow seemingly impossible feats, and why time stubbornly refuses to behave like space. Levin shares the deeply personal Moth story of her son being born a complete mirror image of most people, and how she turns private emotion into structured art. The conversation ranges across writing craft, favorite authors like John McPhee and Cormac McCarthy, poetry, and her hard-won philosophy that life is the obstacles, not a paved path. She closes on finding meaning and connection to the cosmos as an atheist who sees humans as direct descendants of the Big Bang.

• At around 11, Levin grabbed the back of a passing car while skateboarding, hit a break in the road, landed on her head, experienced amnesia, and went into a coma.

• At 16-17 she was in a reckless car crash during a storm that flipped and landed upside down underwater in a canal; everyone survived, leaving her with permanent scars and prompting her parents to send her to college.
  00:07:47
• A switch to physics came when philosopher David Albert gave a guest lecture on Einstein, free will, and quantum mechanics that silenced even the show-offs and mesmerized Levin in the back of the room.
  00:20:23
• Levin's son was born with his heart on the right side and all organs mirror-reversed, an extravagantly rare and healthy condition she and her husband hid for over a decade.
  00:51:07
• Levin first told the mirror-image story publicly in her 2011 Moth talk, and her son only heard the story himself a couple of years before this interview.
  00:54:15
• Levin reveals her ties to Interstellar: Kip Thorne wrote the treatment and won the Nobel Prize for LIGO, was a main character in her book, and was the one person who encouraged her work when she was an unknown.
  01:18:10
• Levin's Tribe of Mentors answer that 'life is the obstacles, there is no underlying path' is a core principle she traces to realizing she'd been falsely sold the idea that life is great and you just shouldn't screw it up.

• Levin uses a teacup to illustrate topology: even made of clay, you cannot remove the hole formed by its handle without breaking it.
  00:33:31
• Pac-Man lives on a two-dimensional donut that is not embedded in any higher-dimensional space, which Levin uses to explain how the universe could be finite and wrap around on itself.
  00:39:43
• In four spatial dimensions you could separate two welded, interlocked steel rings without cutting them, just as in three dimensions you can lift one ring out of another that's trapped on a 2D plane.
  00:46:58
• A right-handed glove taken around a Mobius strip comes back left-handed, a flip of chirality that mirrors her son's reversed anatomy.
  00:49:33
• Traveling near light speed to Andromeda (2.5 million light-years away) and back might feel like a few months to the traveler while 2.5 million years pass on Earth.
  01:16:05
• Einstein quipped that only two things are infinite, the universe and human stupidity, and that he wasn't so sure about the universe.
  01:13:13
• The laws of physics are reversible and show no inherent direction of time: a movie of billiard balls looks sensible run backward, but a blooming versus rotting flower instantly reveals time's arrow.
  01:21:19
• Levin notes humans are direct descendants of the Big Bang and of colliding neutron stars, the only place gold comes from.
  01:29:44
• Maya Angelou's poem 'A Brave and Startling Truth,' which Levin read for Maria Popova's Universe in Verse, flew to space aboard a NASA mission.
  01:42:19
• Physicists originally called the Higgs the 'goddamn particle' before it was rebranded the 'god particle.'
