Defense Intelligence Reference Document Antigravity For Aerospace Applications

Defense Intelligence Agency · 44 pages · text from the file's own layer

This Defense Intelligence Reference Document (DIA-08-1003-018), dated 30 March 2010, was produced by the Defense Intelligence Agency as part of its FY 2009 Advanced Aerospace Weapon System Applications (AAWSA) Program. It reviews theoretical approaches to antigravity for aerospace propulsion, drawing on Newtonian physics, general relativity, cosmological dark energy and quantum vacuum effects. The report notes that no current technology can actively control gravity and that many concepts are far from practicable engineering.

Antigravity for Aerospace Applications
Foreword
Antigravity effects can be implemented by manipulating spacetime. This
paper reviews several different theoretical approaches for exploring the
possibility of controlling gravity by generating forces that counteract, or
otherwise modify, gravity for the purpose of aerospace propulsion. Einstein's
General Theory of Relativity is the theoretical framework guiding this study.
The paper also reviews other antigravity approaches via the interaction of
quantum theory with gravitation. And it explores the question of which
method or technique is best suited for aerospace applications and evaluates
the make-or-break issues that limit them.
