The Final Interview with MIT Physicist Keith Johnson

One of Keith Johnson’s final interviews: a brilliant mind on dark matter, water, and fusion.

This episode is one of the final recorded conversations with MIT physicist Keith Johnson, who passed away just weeks after our interview. In this conversation, he unpacks his early research on the quantum structure of matter, his cold fusion theories, and how it all led to a screenplay about a young female physicist. Johnson also suggests a radical idea: water clusters in space might explain some aspects of dark matter. A one-of-a-kind interview that blends science, art, and speculation.
We’re honored to share this glimpse into Keith’s remarkable intellect, creativity, and curiosity. May his legacy continue to inspire.
