The Scientist That “Discovered Antigravity” Then Disappeared Completely
She also was researching near-zero superconductors

In the summer of 1999, Discover magazine caused a stir in scientific circles with its explosive article on physicist Dr. Ning Li and her revolutionary research into antigravity technology.
Months later she vanished without a trace.
By October 2000 she had vanished into the vast depths of military-industrial obscurity, leaving a trail of tantalizing clues about her breakthrough.
It is the closest science had ever come to discovering an anti-gravity device:
“The device did not modify gravity, rather it produces a gravity-like field that may be either attractive or repulsive,” says Jonathan Campbell, a scientist at the NASA Marshall Space Flight Center who has worked with Li. “It’s a gravity-like force you can point in any direction. It could be used in space to protect the international space station against impacts by small meteoroids and orbital debris.”
Rumors flew about the mysterious scientist and her invention, but the truth remains shrouded in secrecy.
What happened to Dr. Ning Li?
‘Anti-Gravity:’ An Unsolved Mystery
From the smallest molecular particles to entire planets, gravity is a force that binds us all.
It is an attractive power so subtle yet strong to keep celestial bodies in orbit and our feet firmly planted on terra firma. According to physicists, it may be one of nature’s gentlest forces but its touches every corner of existence — from refrigerator magnets and light bulbs, to the heavenly bodies of our vast universe.
Dr. Ning Li wanted to take us one step further and revolutionize how we use gravity. She left the University of Alabama in 1999 to found the company AC Gravity LLC.
What she found was incredible: A ‘high-temperature superconducting disc’ that creates a force field that would effectively neutralize gravity.
In non-nerdy Star Trek speak: An anti-gravity device.
It was far from hoverboards and flying cars, but the invention was real.
