| Status | DEBUNKED |
| Summary | The claim that high-voltage electric fields can produce a propulsive force that counteracts gravity, often called electrogravitics. Some proponents believe this effect works in a vacuum, implying a connection to gravity. |
| Origin | The Biefeld-Brown effect was discovered in the 1920s, and electrogravitics gained attention in the 1950s with claims of secret military research. |
| Claimed |
|
| Evidence / consensus | The Biefeld-Brown effect is caused by ion wind (electrohydrodynamic propulsion). NASA tests in a vacuum showed no thrust, confirming it is not antigravity. |
