Black holes seem to emit positrons. Not sure this helps.


Black holes don't emit anything, Brad.


Search for: black hole positrons

It seems a few thousand (477000) others are not quite so absolute.


You never pay attention to the science, Brad. Pair production
often occurs *near* the "surface" of a black! Black holes don't
emit anything, Brad.

Stop playing games of mainstream status-quo or bust. Go just near or
a little outside the event horizon and there are positrons going most
every which way.

Black holes either attract more than their fair share of positrons, or
they somehow manage to create them.

Brad's overwhelming stupidity aside, one among many reasons this is a
stupid idea is that Hawking radiation is stronger the _less_ massive a
black hole is.

Not at all certain, as there have been no tests to determine
antimatter's gravitational influence direction. That's actually one of
the main reasons why scientists are racing to trap _neutral_ antimatter
*atoms* for long periods of time, to test their reaction to gravity,
without any other forces affecting them.

Why Matter Dominates The Universe


A.
Material Objects Seen as Holes in Space by British Scientist
A close examination of the math of quantum mechanics led to the
prediscovery of antimatter particles in 1930.
http://www.sciencenews.org/view/gene...h _Scientist_

“Today physicists know that every particle has an antiparticle, but
they don’t yet know for sure why matter instead of anti-matter
dominates the universe”.


B.
