This Physicist (Unexpectedly) Derived Gravity from Information

And why "spacetime" may not exist at more fundamental levels

This conversation spans:

  • spacetime emergence from entanglement,

  • why the cosmological constant problem may be a red herring,

  • how time itself can be defined without assuming time (via modular Hamiltonians and density matrices),

  • what computational complexity has to do with black hole interiors,

  • why his twin brother Herman (also a theoretical physicist at Princeton) was formative to his thinking,

  • and why Verlinde believes the right attitude for a scientist is to follow your own nose, not your professor’s.

Erik Verlinde is a professor of theoretical physics at the University of Amsterdam, and in 2010, he dropped a landmark paper that made physicists deeply uncomfortable: he derived Newton’s gravitational force and Newton’s F=ma from entropy. Not analogous to entropy. Literally from entropy. For context, I wrote extensively about both his and Ted Jacobson’s entropic gravity approaches here, where I tried to understand the math and the controversy before this interview. Errors in that piece ar…
