Check out my Reddit post, I go into greater detail on how these work.
In layman's terms, a vaccuum has been created around the skin of the craft. That vaccuum allows the craft to travel at speeds far beyond an SR-71. And, interestingly, allows them to travel underwater!
The US Navy patent doesn't describe a temperature differential, but it's possible that the absence of air (or water) around the skin of the craft is causing a temperature differential and the 'halo' that you see in the videos that were confirmed "authentic" by the Pentagon.
Check out the Navy's patent here : https://patents.google.com/patent/US20170313446A1/
a quote from it:
"An artificially generated high energy/high frequency electromagnetic field (such as the fields an HEEMFG can produce) can fulfill all three conditions simultaneously (especially in an accelerated vibration/rotation mode), when strongly interacting with the local vacuum energy state. These interactions are induced by the coupling of hyper-frequency axial rotation (spin) and hyper-frequency vibration (harmonic oscillations/abrupt pulsations) of electrically charged systems (high energy electromagnetic field generators), placed on the outside of the craft in strategic locations. [0024]
In this manner, local vacuum polarization, namely the coherence of vacuum fluctuations within the immediate proximity of the craft's surface (outside vacuum boundary) is achieved, allowing for ‘smooth sailing’ through the negative pressure (repulsive gravity) of the ‘void’ (the void within the vacuum). It may be stated that the void ‘sucks in’ the craft."
But I must admit I know very little about these things.
- The object had been tracked for 2 weeks by radars: SPY-1 (ship) and E-2 (AWACS aircraft)
- Pilot made naked-eye visual contact with the tic tac from above, watching it move over the water
- There was a cross-shaped wake under it
- It jammed their radar when they attempted a lock, which is why they switched to passive tracking (IR)
- Visual estimate of the speed puts it at faster than mach 3 (SR-71), with instantaneous acceleration
On the show, the pilot pointed out the white "aura" around object in the IR video feed. Since it was set to black-hot, this would mean the nearby air was for some reason colder than the ambient air. He said this was also visible to naked eye as a "bubble." Anyone know of any propulsion that would be associated with a temperature drop to the vehicle surface, along with optical distortion?
Edit: There's a good chance the "aura" is an image processing artifact: https://www.metabunk.org/nyt-gimbal-video-of-u-s-navy-jet-en...
Also since it was black, its surface was hot, not cold.
