For most of the 20th century, the idea of anti-gravity propulsion remained on the margins—dismissed by mainstream science, absorbed into classified military programmes, or reduced to conspiracy lore. But what if the truth was never fringe… only forgotten?
Gravity’s Shadow: The Hidden History of Anti-Gravity Technology is a groundbreaking investigation into one of the most elusive and strategically significant technological frontiers of modern times.
Author Edoardo Giglio—defence strategist and author of Tech Tides—takes readers on a deep archival journey across Cold War-era research, wartime Nazi experimentation, and early 20th-century breakthroughs. His research draws on declassified military documents, underexplored scientific journals, and defence literature rarely studied outside classified circles.
This book is not about fantasy—it’s about facts hidden in plain sight. Across decades and continents, scientists and militaries have quietly explored the possibility of gravity control. Today, as governments renew their interest in Unidentified Aerial Phenomena and advanced propulsion systems, Giglio makes the case that these efforts never truly stopped—only shifted form, name, and priority.
Gravity’s Shadow is the definitive work for readers who want to understand the strategic, scientific, and historical forces shaping the next era of aerospace and energy innovation.
