... A. Einstein's quantum theory of light was based on a hypothesis suggested by the German physicist Max Planck in 1900. 1. Planck stated that the light emitted by a hot object is given off in discrete units or quanta. 2. The higher the frequency of the light, the greater the energy per quantum. 3. All ...

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.
