Contributions To Science and Speculative Science

Benford claims to have created and written about the first computer virus in the late 1960s.

Benford's work in physics at the University of California Irvine has focussed on theoretical and experimental plasma physics, including studies of extremely strong turbulence, particularly in astrophysical contexts, and studies of magnetic structures from the galactic center to large scale galactic jets. Working in collaboration with, among others, science fiction writers Cramer, Forward, and Landis, Benford worked on a theoretical study of the physics of wormholes, which pointed out that wormholes, if formed in the early universe, could still exist in the present day if they were wrapped in a negative-mass cosmic string. Such wormholes could potentially be detected by gravitational lensing.

In 2004, Benford proposed that the harmful effects of global warming could be reduced by the construction of a rotating Fresnel lens 1,000 kilometres across, floating in space at the Lagrangian point L1. According to Benford, this lens would diffuse the light from the Sun and reduce the solar energy reaching the Earth by approximately 0.5% to 1%. He estimated that this would cost around US$10 billion. His plan has been commented on in a variety of forums. A similar plan was proposed in 1989 by J. T. Early, and again in 1997 by Edward Teller, Lowell Wood, and Roderick Hyde. In 2006, Benford pointed out one possible danger in this approach: if this lens were built and global warming were avoided, there would be less incentive to reduce greenhouse gases, and humans might continue to produce too much carbon dioxide until it caused some other environmental catastrophe, such as a chemical change in ocean water that could be disastrous to ocean life.

Benford serves on the board of directors and the steering committee of the Mars Society.
