Here is a question about the energy conservation in the Dirac sea model?
In the Dirac sea a particle-antiparticle couple can be created, and then annihilate in such a short time that the energy conservation principle is not violated. Say I have two photosensitive parallel plates placed in vacuum, and distance between them < < their size . If I wait for an infinite time, a couple of […]
Ion Propulsion question?
NASA’s Deep Space 1 probe used ion propulsion technology to propel it into outer space. Ion propulsion uses an electric charge to ionize atoms such as xenon. These ions are funneled from the exhaust of the craft at such high speends that it is pushed in the opposite direction and propelled into space. The electrical […]
