Description

A groundbreaking investigation into one of the most elusive and strategically significant technological frontiers of the last century.

For much of modern history, the concept of anti-gravity propulsion has been met with scepticism or silence. Yet scattered across the archives of 20th-century warfare and aerospace development lies a compelling pattern: scientific research, state-backed experimentation, and military programs quietly exploring the possibility of gravity control.

Gravity’s Shadow is the first comprehensive account to bring together these diverse and often overlooked efforts, tracing a narrative that spans from early 20th-century theories to Cold War-era experimentation, and into the present day. Drawing on declassified military documents, technical reports, and under-explored scientific literature, the book examines how various nations—including Nazi Germany, the Soviet Union, and the United States—have engaged in attempts to develop breakthrough propulsion systems that challenge conventional physics.

Rather than speculative or sensational, this is a work of serious research and critical analysis, authored by Edoardo Giglio, a defence and technology strategist, and author of Tech Tides: How Innovation Shapes Global Power (Bloomsbury, 2025). With a background in STEM disciplines, intelligence operations, and global strategy, Giglio offers a unique perspective on how these technologies have been explored, obscured, and sometimes quietly re-evaluated under new programs and priorities.

At a time when governments are publicly acknowledging unexplained aerial phenomena and renewing interest in advanced propulsion systems, Gravity’s Shadow provides a timely and carefully reasoned account of a subject long misunderstood—and increasingly relevant to the future of aerospace, energy, and strategic competition.
