Ning Li’s Antigravity Research and Mysterious Disappearance

Dr. Ning Li’s research into superconductors promised a technological revolution, attracted NASA and Army funding, and made international headlines. Then she disappeared from public science. Decades later, new testimony and surviving government records reveal a more complicated story of ambitious physics, unfinished experiments, military secrecy, and personal tragedy.

For years, Dr. Ning Li was one of the most intriguing missing figures in American science. A physicist working in Huntsville, Alabama, she had proposed something extraordinary: that superconducting materials might be used to generate and control gravitational forces. Her research attracted NASA scientists, national media coverage, and eventually nearly half a million dollars in funding from the U.S. Army. Then, in the early 2000s, her publications largely stopped, her company went quiet, and attempts to contact her produced little information.…
