does anyone know more about this phenomena ? the discharge of electricity in the ionosphere that results as a "backflash" of lightning discharge


I know they have been studying these things, but I havent seen yet what they found out -- I mean is it just charged particles or is there some strange thing going on-- or is it just a negative or positive to the lightnings shot?

Microcopic black holes, according to some - and the same thing would be inside a ball lightning, according to others. Hawking would predict those to be very short-lived, due to Hawking Radiation, as they would appear to do, and I don't think there's really anything ruling that possibility out.

Personally I have some problems with the giga-black holes out in space, but not so much with those tiny mini-holes.

"The energies we see are as high as those of gamma rays emitted from black holes and neutron stars," said David Smith, an assistant professor of physics at UC Santa Cruz and author of a scientific paper on this topic.

Yes, it's official. Mini black holes in the upper atmosphere.

I can understand the confusion, but I was serious:

'Micro black holes

The formation of black hole analogs on Earth in particle accelerators has been reported,[32]. These black hole analogs are not the same as gravitational black holes, but they are vital testing grounds for quantum theories of gravity.

They act like black holes because of the correspondence between the theory of the strong nuclear force, which has nothing to do with gravity, and the quantum theory of gravity. They are similar because both are described by string theory. So the formation and disintegration of a fireball in quark gluon plasma can be interpreted in black hole language. The fireball at RHIC is a phenomenon which is closely analogous to a black hole, and many of its physical properties can be correctly predicted using this analogy. The fireball, however, is not a gravitational object.'
