An Astronomer Explains Black Holes in 5 Levels of Increasing Complexity

posted by Jason Kottke   Jan 21, 2020

In this video from Wired’s 5 Levels series, NASA astronomer Varoujan Gorjian explains the concept of black holes to five different people, ranging from a five-year-old to a college student to a Caltech astrophysicist.

A research astronomer at NASA’s Jet Propulsion Laboratory, Grojian specializes in — and I’d just like to pause here to emphasize that this is the official title of his research group at JPL — the structure of the universe. Which means the guy not only knows about event horizons and gravitational lensing but stuff like tidal forces (what!), x-ray binaries (hey now!), and active galactic nuclei (oh my god!). Seriously, the guy’s knowledge of black holes is encyclopedic.

Gorjian lost me somewhere in the middle of his conversation with the grad student.
