Transmedium / 'five observables' claim.
allegedhypothesisScientific Instrumentation & Sensor Data
Anomalist thesis that Navy UAP exhibit five observables - anti-gravity lift, instant acceleration, hypersonic-without-signature, low observability, and air-to-water transmedium travel - implying non-human or breakthrough technology.
Popularized by Navy/AATIP-adjacent figures and SCU, the 'five observables' frame the Nimitz/2015 events as displaying physics beyond known engineering. The transmedium element (objects entering/exiting water, e.g. the Nimitz whitewater disturbance, USS Omaha 2019, Aguadilla 2013) is the most extraordinary. It is a claim: it depends on accepting the radar tracks and FLIR-derived kinematics at face value, which skeptical analyses and AARO do not.
