The topics in this book have fascinated people for millennia, inspiring novels, films, and TV shows. We took four recently declassified U.S. Government reports on advanced topics and combined them into one book.
Invisibility Theory and Experiments Invisibility cloaking has recently become a subject of science and technology. This paper describes the important current theoretical and experimental developments and tries to project into the future.
Antigravity for Aerospace Applications 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.
Traversable Wormholes, Stargates, and Negative Energy This paper is about FTL (Faster Than Light) interstellar travel via traversable wormholes. Wormholes are hyperspace tunnels through spacetime connecting either remote regions within our universe or two different universes; they even connect different dimensions and different times.
Warp Drive, Dark Energy, and the Manipulation of Extra Dimensions To explore space beyond our solar system within a human lifetime, we need to significantly change the way we propel spacecraft. The main focus this paper, the warp drive, involves local manipulation of the fabric of space in the immediate vicinity of a spacecraft. The basic idea is to create an asymmetric bubble of space that is contracting in front of the spacecraft while expanding behind it.
