They said it defied physics. They dismissed it as fringe. But what if they were wrong?
From Leonardo da Vinci’s forgotten experiments to the Cold War’s darkest aerospace secrets, from Nazi “wunderwaffe” and Die Glocke to the mystery of Dr. Ning Li’s disappearance — Gravity’s Shadow unveils the hidden, classified, and often tragic history of humanity’s quest to conquer gravity.
In his most daring work yet, Edoardo Giglio, author and founder of Hangar 51 Files, traces a century-spanning story of invention, suppression, and silence. Were antigravity breakthroughs buried beneath black projects and false flag operations? Have we already developed the technology — and deployed it under the name of UAPs?
This is not science fiction. This is science silenced.
🎙️ And now — Gravity’s Shadow: The Audio Primer — a short introductory Hangar 51 Files podcast episode is out now. In less than 10 minutes, hear the story behind the book, the research that went deeper than anyone expected, and what might still be hidden in plain sight.
“The universe is not a prison. It is a playground, if only we have the courage to see it.” – Thomas Townsend Brown
