A "craft using an inertial mass reduction device" (2016), one embodiment of which could be a high speed "hybrid aerospace/undersea craft" able to "engineer the fabric of our reality at the most fundamental level", [7] the patent application for which was supported by the Naval Aviation Enterprise's chief technical officer on the grounds that ...
Objects also have "inertial mass," which determines the relationship between the force applied to an object and how much it accelerates. Newton had pointed out that, even though they are defined differently, gravitational mass and inertial mass always seem to be equal. But until Einstein, no one had conceived a good explanation as to why this ...
In physics, reduced mass is a measure of the effective inertial mass of a system with two or more particles when the particles are interacting with each other. Reduced mass allows the two-body problem to be solved as if it were a one-body problem. Note, however, that the mass determining the gravitational force is not reduced.
“That sounds weird,” Russell admitted, because “I can tell you how to make one.” But “how they work, we don’t know. We don’t know if they know things.
He reported plans to have the device ready to use in space by May 2009 and to make the resonant cavity a superconductor, [40] neither of which materialized. New Scientist magazine [4] featured the EmDrive on the cover of 8 September 2006 issue. The article portrayed the device as plausible and emphasized the arguments of those who held that ...
This year, using the Joint European Torus facility in Oxford, England, a group of several hundred researchers called EUROfusion produced over 20 times as much energy as NIF’s first ignition just ...
NASA artist rendering, from 1999, of the Project Orion pulsed nuclear fission spacecraft. Project Orion was a study conducted in the 1950s and 1960s by the United States Air Force, DARPA, [1] and NASA into the viability of a nuclear pulse spaceship that would be directly propelled by a series of atomic explosions behind the craft.
In astronautics and aerospace engineering, the bi-elliptic transfer is an orbital maneuver that moves a spacecraft from one orbit to another and may, in certain situations, require less delta-v than a Hohmann transfer maneuver. The bi-elliptic transfer consists of two half elliptic orbits.
