Electric GRBs

The gamma rays come firstly in pulses and the weaker photons follow. This exludes all hot sources which send either the infrared photons at first (by a heat-up process) or all photons at once. The source must be cold. The short and sharp gamma pulses exclude all larger source than 0.1 lightseconds and all far sources due to the missing gravity-lense effect. The measured redshift of the afterglow can be simulated by the exploded shell which glows in its inside due to the collision by the cold explosion. Second "Big Bangs" ? Much weaker sources must be found in our proximity. The cold (electric) explosion of a white dwarf meets all these characteristics: start with gamma pulses, relativistic protons a.s.o. Moreover, white dwarfs have a low limit of their masses due to the limited age of the Universe (too few weak bursts !). White dwarfs are everywhere, their HRD branch is amputed at about 7000 K i.e. they probably explode before they become red.
