Paradox of radiation of charged particles in a gravitational field electric field has an accompanying magnetic field, and the whole oscillating electromagnetic radiation field propagates independently of the accelerated charge, carrying away momentum and energy. The energy in the radiation is provided by the work that accelerates the charge. The theory of general relativity is built on the equivalence principle of gravitation and inertia. This principle states that it is impossible to distinguish through any local measurement whether one is in a gravitational field or being accelerated. An elevator out in deep space, far from any planet, could mimic a gravitational field to its occupants if it could be accelerated
A Web of Sound A Web of Sound A Web of Sound is the second album by the American garage rock band the Seeds. Produced by Marcus Tybalt and released in October 1966, it contained the single "Mr. Farmer" and the 14-minute closing song "Up In Her Room".
