In July 1998 physicists Bernhard Haisch, Alfonso Rueda and Hal Puthoff presented a paper to a major propulsion conference proposing that inertia — an object's resistance to being accelerated — might arise from the quantum vacuum's electromagnetic "zero-point field" acting on accelerating matter. The research was partly funded by NASA.[1][2]
The paper

"Advances in the proposed electromagnetic zero-point field theory of inertia" was an invited presentation at the 34th AIAA/ASME/SAE/ASEE Joint Propulsion Conference in Cleveland, Ohio, on 13–15 July 1998 (paper AIAA 98-3143), and was posted to the arXiv preprint server that month. The NASA-funded work was carried out at the Lockheed Martin Advanced Technology Center in Palo Alto, where Haisch worked, and at California State University, Long Beach, where Rueda taught; Puthoff ran the Institute for Advanced Studies at Austin.[1]
The theory

The authors argued that Newton's law of motion could be derived from Maxwell's equations applied to the zero-point field, so that mass would be a kind of electromagnetic drag that depends on acceleration rather than an intrinsic property of matter. They extended an exploratory study first published in 1994 into a relativistic version. Because the equivalence principle links inertia and gravity, gravity too would be electromagnetic in origin. They concluded that matter with negative inertial mass is impossible, ruling out one proposed propulsion idea, but suggested that the links between the zero-point field, inertia and gravity might in principle allow inertia and gravity to be manipulated, while stressing that this was speculative.[1][2]
Reception
The papers were published in physics journals, including Physics Letters A in 1998, and attracted both interest and criticism. The idea remains a minority hypothesis that has not been confirmed experimentally or gained mainstream acceptance.[2][3]
Connections

The work was part of a wider interest in exotic propulsion that included NASA's Breakthrough Propulsion Physics program. Puthoff later chose the topics for the Pentagon-funded AAWSAP technical reports. The testimony notes that a 2017 Navy patent by engineer Salvatore Pais, for a craft using an "inertial mass reduction device", draws on similar concepts; that patent has not been shown to describe working technology.[3][4]
