Antigravity and UAP

Where the physics stands

No experiment accepted by mainstream physics has shown a device that cancels or reverses gravity. General relativity allows strange things on paper, such as warp bubbles and wormholes, but they need negative energy or amounts of energy nobody knows how to make.

The subject keeps coming back because of UAP reports. One of Luis Elizondo's five observables is lift with no wings, rotors or exhaust, and pilots like David Fravor described objects that moved with no visible means of flight. If those reports are accurate, something is doing what known aircraft can't.

The research, in order

1. 1920sThe Biefeld-Brown effect

   Thomas Townsend Brown, working with the physicist Paul Biefeld, found that a high-voltage capacitor pushes itself in one direction. Brown believed it was a link between electricity and gravity. Later tests, including a 2002 US Army Research Laboratory study, put the push down to ion wind, which doesn't work in a vacuum.

2. 1948Gravity Research Foundation

   The investor Roger Babson founded a foundation to look for ways to block gravity. It turned into a respected yearly essay prize on gravity that leading physicists still enter.

3. 1952Project Winterhaven

   Townsend Brown proposed a military program to build electrogravitic craft. It was not adopted, as far as public records show.

4. 1955 to 1956The aerospace gravity rush

   Trade magazines reported gravity research at Glenn L. Martin, Convair, Bell and other aircraft makers. Bill Lear, the Learjet founder and father of John Lear, spoke publicly about the work. A 1956 British report, Electrogravitics Systems, surveyed the field. Then public talk went quiet, which some researchers read as the work going classified and others as the work going nowhere.

5. 1989Bob Lazar's gravity amplifier

   Bob Lazar said the craft he worked on at S-4 flew on gravity amplifiers powered by element 115. Element 115 (moscovium) was first made in a lab in 2003; it lasts a fraction of a second, and no stable form has been found.

6. 1992Podkletnov's spinning superconductor

   The Russian engineer Eugene Podkletnov reported that a spinning superconducting disc made objects above it lose about 2% of their weight. A NASA team at Marshall Space Flight Center built a version and found no effect.

7. 1994The Alcubierre warp drive

   The physicist Miguel Alcubierre showed that general relativity allows a bubble of space to move faster than light, if exotic negative energy exists. It is still the reference point for warp drive talk.

8. 1996 to 2002NASA Breakthrough Propulsion Physics

   A small NASA project led by Marc Millis tested and reviewed ideas for new propulsion, including gravity control. It found no working method and was closed in 2002.

9. 2009 to 2011The AAWSAP papers

   AAWSAP paid for 38 technical papers on future aerospace science. Hal Puthoff wrote on engineering the vacuum of space for propulsion, and Eric Davis on wormholes and negative energy. Their titles were released in 2018, and many of the papers have since come out through FOIA requests.

10. 2016 to 2019The Navy patents

    The Navy engineer Salvatore Pais filed patents for a craft using an inertial mass reduction device and for related high-energy devices, assigned to the US Navy. Later reporting said a small Navy-funded test did not show the effect.
