One of Keith Johnson’s final interviews: a brilliant mind on dark matter, water, and fusion.Read about Keith’s legacy here: https://news.mit.edu/2025/keith-johnson-materials-scientist-independent-filmmaker-dies-0723This 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.Follow us for more technical interviews with the world’s greatest scientists:Twitter: https://x.com/632nmPodcastInstagram: https://www.instagram.com/632nmpodcast?utm_source=ig_web_button_share_sheet&igsh=ZDNlZDc0MzIxNw==LinkedIn: https://www.linkedin.com/company/632nm/about/Substack: https://632nmpodcast.substack.com/Follow our hosts!Michael Dubrovsky: https://x.com/MikeDubrovskyMisha Shalaginov: https://x.com/MYShalaginovXinghui Yin: https://x.com/XinghuiYinSubscribe:Apple Podcasts: https://podcasts.apple.com/us/podcast/632nm/id1751170269Spotify: https://open.spotify.com/show/4aVH9vT5qp5UUUvQ6Uf6ORWebsite: https://www.632nm.comTimestamps:00:00 - Intro01:03- Early Life and Education03:27 - Graduate Studies and Research Funding05:44 - Postdoctoral Work and Quantum Chemistry09:45 - Starting at MIT and Collaborations15:05 - Cold Fusion and Film Making23:38 - Keith's First Screenplay28:55 - Filming a Movie at MIT43:50 - Water Clusters and Quantum Energy53:54 - Is Cold Fusion Possible?1:07:13 - Challenges in Fusion Energy1:12:09 - Advice for Young ScientistsAPPENDIX:1:15:42 - Water Might Be Connected to Dark Matter1:24:49 - Cosmic Dust and Supernovae1:28:36 - The Role of Water in the Universe1:38:32 - The Future of Dark Matter Research1:51:27 - Water Might Have Been Created Sooner After the Big Bang#KeithJohnson #MIT #ScienceAndStorytelling #QuantumPhysics #DarkMatter #Astrobiology #BreakingSymmetry
