Gravitational and electricenergies in gravitational collapses |
|
Abstract |
We discuss in gravitational collapses how gravitational energy is converted to both kinetic and electric energies in form of electron-positron-photon plasma. It is shown that (i) averaged kinetic and electric energies are the same order, about an half of gravitational energy of stellar cores in collapse; (ii) caused by radiating and rebuilding electric energy, gravitational collapse undergoes a sequence of ``on and off'' hopping steps in the microscopic Compton scale, and it is slowed down as kinetic energy is reduced and collapsing time becomes longer. |
