... Which is more difficult to stop: A tractor-trailer truck barreling down the highway at 35 meters per second, or a small two-seater sports car traveling the same speed? You probably guessed that it takes more force to stop a large truck than a small car. In physics terms, we say that the truck has gr ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
