What does Newcomb's paradox teach us? (2010)
Wolpert, David H., Benford, Gregory
In Newcomb's paradox you choose to receive either the contents of a particular closed box, or the contents of both that closed box and another one. Before you choose, a prediction algorithm deduces...
Cost Optimized Interstellar Beacons: METI (2008)
Benford, James, Benford, Gregory, Benford, Dominic
This paper considers galactic scale Beacons from the point of view of expense to a builder on Earth. For fixed power density in the far field, what is the cost-optimum interstellar Beacon system?...
Cost Optimized Interstellar Beacons: SETI (2008)
Benford, Gregory, Benford, James, Benford, Dominic
What would SETI Beacon transmitters be like if built by civilizations with a variety of motivations, but who cared about cost? High-power transmitters might be built for wide variety of motives other...

Fossil AGN jets as ultra high energy particle accelerators (2007)
Benford, Gregory, Protheroe, R. J.
Remnants of AGN jets and their surrounding cocoons leave colossal magnetohydrodynamic (MHD) fossil structures storing total energies ~10^{60} erg. The original active galacic nucleus (AGN) may be...

Stability of Magnetic Equilibria in Radio Balloons (2006)
Current-carrying flows, in the laboratory and in astrophysical jets, can form remarkably stable magnetic structures. Decades of experience shows that such flows often build equilibria that reverse...
Collective Microwave Emission from Intense Electron-Beam Interactions: Theory and Experiment, (2002)
Advanced technology paths to global climate stability: Energy for a greenhouse planet (2002)
Martin I. Hoffert, Ken Caldeira, Gregory Benford, David R. Criswell, Christopher Green, Howard Herzog, ...
Stabilizing the carbon dioxide–induced component of climate change is an energy problem. Establishment of a course toward such stabilization will require the development within the coming decades...

High Power, High Frequency Radiation from Beam-Plasma Interactions. (1998)
A theory has been developed for the probability distribution of the electric field in a highly turbulent plasma environment, Experimental optical studies have been carried out to quantify the...
A new Stark effect diagnostic was used to measure the E-field distribution of Langmuir waves in beam-plasma turbulence. Abrupt beam cut off causes the distribution's amplitude to decay exponentially...
Work Performed Experiments: 1989-1990. (1998)
Studied was an X-band Backward Wave Oscillator (BWO) which could be filled both with a hard vacuum and with plasma. The observed power output was about 40MW in the vacuum BWO with a frequency of 8.5...
Final Report on Grant N00014-88-K-0425 (California Univ.). (1998)
We summarize advances in the general understanding of strong plasma turbulence, with special application to the mechanisms for powerful microwave emission. Principally, we developed an optical...

Natural Wormholes as Gravitational Lenses (1994)
Cramer, John G., Forward, Robert L., Morris, Michael S., Visser, Matt, Benford, Gregory, Landis, Geoffrey A.
Visser has suggested traversable 3-dimensional wormholes that could plausibly form naturally during Big Bang inflation. A wormhole mouth embedded in high mass density might accrete mass, giving the...
