Write your reply.

assistant: Besides fields and particles, one has the geometric point of view.  I suspect
that this is the view of the future, moreso than either the particle or the
field view, but I could well be wrong.
Basically, we know that according to general relativity (GR), black holes can
have an electric charge (note I'm talking about theory here, not
bservation).
I usually try to make it clear that I'm almost always talking about theory
GR
specifically) when I talk about black holes.
GR makes this prediction because electric charge is conserved by
the theory, Electric charge of a BH is defined by Gauss's law (one integrates
the component of the electric field passing through a sphere around the black
hole to get the value for charge.)
The conservation of electric charge strikes me as a good feature of any
heory
of black holes, however, not just GR.  Any theory which is going to conserve
charge must allow electric fields to escape a black hole.
From the particle point of view, this involves the exchange of virtual
hotons
(I'm not real fond of that view personally, as I mentioned before, however.)

Merhaba Sid,
 That was not what I wanted, for sure. I must have been absent-minded then,
 thinking everyting I knew on Venus...I remembered the phases, but I sure
 know the best "full" view of the planet seen from earth is when we see 30%
 of total illuminated surface. Full Venus can never be seen (I wonder what
 the luminosity would have been if that were possible?).

Merhaba Sid,
 Fine hairs? That is most interesting...I am a dentist, so I am familiar
 with the human body. Whoever came up with this idea was a very creative
 person!
 I still believe the sounds can be recorded on tape using suitable
 equipment. The noise probably appears on the edge of audible spectrum. If
 you had experienced it, you might answer a few questions of mine, for ex.,
 does the sound seem to be a low frequency one (a loud boom or howling) or
 a high frequency one (sharp, shrill sound).
 I once considered immigrating to Canada, then I got scared of the cold :)

On 19 Dec 97, W Boson wrote to Arnold G. Gill:
     I don't think it would work.  The idea is that infalling charges would
have their field motion time dilated as they fell through the event horizon.
But this implies that the charges appear "frozen" on the surface, and the
electromagnetic fields remain very assymmetric.  Yet, black hole theory
suggests that after some period of time, gravitational oscillations will
remove any non-spherical components and one will be left with a charged Kerr
black hole.  The two ideas seem contradictory.  Perhaps they are not.
Perhaps it is a paradigm of two different observers?  I just don't know.

Glad you did.  I am one of the extremely widespread.  Was.  A "do I

This does not mean Uranus rotates in two planes, right?  Pole 1 only

correct?

The gravitational charge to mass ratio of the electron is 10^-40.
Charges imply a particle with mass. One would therefore be accumulating
more mass than charge.
Magnetic field density I think can be much higher than this. Rotating
fields are easy to make and as a limit can rotate at the speed of light.
This is somewhat analogous to mid ocean waves which can travel fast
though none of the water actually moved.
It may be impossible to reach the required energy density after all and
like you say it would be more productive to accelerate a massive charge.
