Race to Control Gravity (02:36)


Scientists do not fully understand the force binding the universe. Corporations, governments, and military invested in exploratory research to manipulate gravity.

Project Greenglow Introduction (03:58)

In the 1990s, British aerospace engineer Ron Evans asked his employers at BAE Systems to let him try to levitate a plane using gravity. In 1996, NASA engineer Marc Millis managed a project researching gravity manipulation. Both organizations refuse to discuss the projects.

Anti-Gravity Trick (02:53)

Engineering professor Eric Laithwaite suggested spinning a gyroscope could counteract gravity. Evans and Dr. Adam Wojcik recreate his experiment that produces an illusion of losing weight. Laithwaite's claim that it was anti-gravity damaged his reputation; Evans believes such technology is possible.

Gravity Manipulation Dream (03:56)

Dr. Tamara Davis demonstrates how electromagnetism gives us the illusion of gravity control. However, gravity only has a positive polarity. Professor John Ellis explains how gravity adds up as matter increases and mass generates an attractive force.

Anti-Gravity Claim (02:15)

In 1996 in Finland, Russian scientist Dr. Eugene Podkletnov was using a cryostat to cool electrical superconductors and noticed smoke rapidly propelled upwards. He believed he had created an anti-gravity field using a vacuum chamber and a rotating disk.

Reproducing the Gravity Field (02:33)

The British Ministry of Defense asked Evans to investigate Podkletnov's claim that a spinning superconductor could change gravity. BAE Systems lacked the budget to try the experiment and Millis' team was unable to replicate the results.

Anti-Gravity Military Potential (02:41)

Podkletnov left his university post to work for Moscow. He met with Evans in secret at a London hotel about his new impulse gravity generator. He says it could be used for propulsion in space and interrupt missile trajectories.

Testing Podkletnov's Gravity Pulse Generator (04:15)

In the early 2000s, new scientists joined Project Greenglow. Space systems professor Martin Tajmar explains his giant spark plug, where an electronic pendulum should sense gravitational impulses run through a superconductor. However, they do not appear on a data chart.

Scale in Gravity Control (02:02)

Physicist Clifford Johnson demonstrates gravity's weakness compared to electromagnetism. Its effects can only be measured with huge amounts of mass.

Breakthrough Propulsion Project (02:12)

NASA aims to develop an alternative to rocket fuel for thrust against gravity. Millis explains why travel beyond the Moon is impossible with conventional rockets.

EM Drive (03:49)

Aerospace engineer Roger Shawyer invented a device using microwave energy to propel itself in space without rocket technology. He believes it could lift from Earth, if large enough. Theoretical scientists argue that it cannot generate thrust or momentum.

Testing the EM Drive (03:00)

Tajmar's team places the device inside a vacuum chamber on dampers. Sensors indicate a tiny amount of thrust during the initial experiment, but it does not correspond when tilted 90 degrees.

Ending Gravity Control Research (01:51)

NASA closed down Millis' Breakthrough Propulsion Project in 2002, but he is pleased at having developed concepts to the first step in the scientific method. When Ron Evans retired, BAE Systems closed Project Greenglow.

Dark Energy and Anti-Gravity (02:20)

Johnson and Davis explain that the universal expansion is accelerating— a phenomenon puzzling theoretical physicists. The anti-gravity force seems to originate from space.

Quantum Physics and Dark Energy (03:08)

Dark energy may appear spontaneously in the space vacuum with subatomic particles. Using a magnet and iron filings, Dr. Dragan Hajdukovic demonstrates how particle pairs create an anti-gravity dark energy halo around every mass. Gravity may be repulsion between matter and anti-matter.

Alpha Experiment (02:19)

Under Professor Jeffrey Hangst, CERN scientists are building a machine to test Hajdukovic's theory that anti-matter causes gravity. If hydrogen anti-matter particles fall away from Earth’s gravity, his theory is right— and anti-gravity may eventually be produced.

Quantum Gravity Gradiometer (03:57)

Gravity's negative form could exist in quantum physics. Neil Stansfield shows Evans a device using lasers to freeze a cloud of atoms responding to disturbances in Earth's gravitational field caused by moving mass. He believes gravity control will be possible someday.

For the last 200 years, we have been fascinated with the idea of controlling gravity. But in the mid-1990s British aerospace manufacturer BAE Systems began a ground-breaking project code-named "Greenglow" which set about turning what many regarded as science fiction into reality. On the other side of the Atlantic, NASA was simultaneously running its own Breakthrough Propulsion Physics Project. It was concerned with potential space applications of new physics, including concepts like "faster than light travel and "warp drives." Looking at these past projects and into the future, this BBC Horizon program explores science’s obsession with the idea of gravity control. Are flying cars and journeys to the stars still the stuff of dreams?
