Anti-gravity research seeks a way to reduce, cancel, shield, or reverse gravitational attraction without relying on ordinary aerodynamic lift or thrust. In established physics, gravity is described by general relativity as the curvature of spacetime, and the equivalence principle links gravitational and inertial acceleration. Precision experiments continue to test those foundations, but no reproducible device has demonstrated gravity shielding or controllable repulsion. Laboratory claims must also separate a gravitational effect from magnetic, thermal, electrostatic, or mechanical forces.

Aerospace interest grew during the 1950s as companies and researchers explored whether new gravitational physics could enable propulsion. Later work examined quantum vacuum effects, inertia, superconductors, and speculative metric engineering. NASA’s Breakthrough Propulsion Physics program reviewed high-risk concepts before ending in 2002. Studying gravity, quantum gravity, or exotic propulsion is legitimate science; the label “anti-gravity” can overstate what an experiment actually measures.

UAP accounts intensify the subject because witnesses describe silent hovering, rapid acceleration, and flight without visible control surfaces. Bob Lazar attributed such behavior to gravity emitters, while Navy inventor Salvatore Pais received patents for unconventional propulsion concepts. Patents and testimony show that ideas were proposed, not that working systems achieved their claimed performance. Apparent motion in sensor data also requires range and geometry before it becomes a propulsion measurement.

The real significance of anti-gravity research lies in the gap between open theoretical inquiry and recurring claims of operational classified craft. Discoveries that violate or extend known gravity would have consequences well beyond UAP. At present, Quantum Gravity remains an unresolved theoretical frontier, whereas practical anti-gravity remains unverified technology.

This UAP video shows motion illusions from parallax (a turning and moving platform) and manual tracking. In the unstabilized (2nd) video, the motion illusion looks quite convincing! Consistent with a balloon or an antigravity non-human craft. You be the judge. https://t.co/B5dvEJLruj

This UAP is consistent with a balloon. That does not mean it IS a balloon, just that it quite possibly could be one. It could also be an anti-gravity drone from an alien spaceship or undersea base. But we know there are lots of balloons. https://t.co/J2a0rTVZuE

DOW-UAP-D134, AAWSAP DIRD, Maverick Inventor Versus Corporate Inventor: Where Will the Next Major Innovations Arise, March 2010

Department of War19 pagesSep 18, 2026RELEASE-06-FILE-038-DOW-UAP-D134-AAWSAP-DIRD-MAVERICK-INVENTOR-VERSUS-CORPORATE-INVENTOR-WHERE-WILL-THE-NEXT-MAJOR-I

This DIA reference compares five types of independent inventor with corporate and university researchers in advanced energy and propulsion. It favors technically trained, experimentally disciplined mavericks while arguing that institutional teams can compete when given freedom, motivation, strong measurement practice and long-term support.

[Retweeted] Palantir CEO Alex Karp says an unnamed U.S. general asked him if he could build an “alien anti-gravity machine,” raising questions about whether the request may have been related to reverse engineering recovered non-human technology. Karp shared the story during a talk at AIPCon 11 while discussing the challenges of working with government contracts. https://t.co/YOUqiM16cF

Full quote is "He was like 'build me this bullshit alien anti-gravity machine that also tells me I'm brilliant.' And one of my forward deployed engineers literally told the general, 'but you're not smart enough to know how dumb you are now’” Clearly he was being derisive of the request, but the fact that he was being asked to build an “alien anti-gravity machine” is extremely noteworthy. Who requested this? Which contractor was chosen? What is this machine? Time stamped link below https://you...

Alex Karp, CEO of Palantir, describes a conflict his company had with the US government that ultimately resulted in a lawsuit. He explains that the core of the dispute involved a military general who, in Karp's view, lacked a fundamental understanding of technology despite his battlefield experience. According to Karp, the general approached Palantir with a request to build an alien anti-gravitic craft. The situation reached a breaking point when one of Palantir's forward-deployed engineers d...

I've always wondered which UFO theories are purposeful disinformation designed to throw geo-political rivals, on a wild goose chase. Perhaps anti-gravity is one of them? The most common unexplainable propulsion characteristics we see with the UAPs is insane acceleration, and they don't seem to interact with the atmosphere (no wake, no sonic boom, etc). Even if the UAPs had the means to cancel out or reduce the effects of gravity, they'd still have to worry about inertia and fluid interactions...

If you used something like a wormhole or the gravity machines Bob Lazar described to quickly travel those distances, then in theory, you could go to a galaxy 70 million light years away and look through an advanced telescope and you could see dinosaurs walking around on Earth? You'd be watching the past. Wouldn't that be a wild ride. You could actually observe our past, record it on a recorder and then come back and show everybody dinosaurs from 70 million years ago.
