Dr. Blitz
Dr Samuel (Sam) Blitz is an American mathematical physicist whose professional career consists of expanding humanity's scientific understanding of gravity. He also regularly speaks to people who don't think gravity is real.
Blitz received his doctorate in physics from the University of California, Davis in 2022, and has since worked with research groups around the globe to study the geometry of spacetime.
He hosts TikTok livestreams (which are also broadcasted to his YouTube channels) where he offers to debate people on various topics, including atheism, creationism, MAGA, and of course flat Earth. Aside from debating the dumbest people on the planet, he posts educational content to his social media explaining complicated and interesting concepts in physics.

Angels of Shite
- Further reading: Angels of Light#Protractors are flat therefore erf flat
In June 2026 Angels of Light appeared on Blitz's TikTok live, and totally proved flat erf by pointing to the bottom of a protractor. Other highlights of the "debate" include Angels completely fumbling basic relativity, claiming the velocity of a runway relative to a landing plane is zero. The interaction was clipped and uploaded to the Dr Blitz Debunks YouTube channel: "Famous flat earther LITERALLY schooled on basic physics"
Angels was brave enough to upload parts of the interaction to his YouTube channel: "Dr blitz PhD getting destroyed by Angels of Light blitz proves a flat earth then runs away" Of the nearly 50-minute interaction, Angels could only find 3 minutes worth that he was not too embarrassed to include.
