Hal Puthoff
Physicist who raised a spacetime-distortion/warp-bubble UAP propulsion hypothesis at the June 25, 2026 Senate Disclosure Forum science panel (alongside avi-loeb) and in a same-day podcast with Rep. eric-burlison. avi-loeb subsequently argued (in src-loeb-orbs-fireballs-council-2026-07) that even warp-bubble propulsion would still produce a fireball and sonic boom via air-shock heating, challenging the hypothesis on physical grounds.
