...just maybe...a positron is an area of space that
is lacking an electron. I think that Richard Feymann was thinking along
similar lines with his concept of virtual particles. Stephen Hawking
suggested that, near a black hole event horizon, anti-particles would be
generated from nothingness when their quantum entangled virtual twins
disappear into the singularity. Hence black holes will radiate Hawking
radiation. . . .

'Lo Sally --

I've been studying this and would like to hear more about it . . .

. . . So the question arises, how would an electron-less area of
space be able to leave the bubble track that is left by a positron
when it is created in a cloud chamber?


I think Sally is describing Dirac's original theory about anti-matter. I
don't have a good reference to hand (searching for "Dirac" and
"positron" will probably tell you a lot more) but AIUI a positron is a
"hole" in a sea of particles with negative energy.

That might explain it. Her ref. was to Feynman and virtual
particles, but i found nothing about it there.

I was also unaware that Dirac's prediction was about holes
rather than negatively charged particles. Something they
leave out these days?

As for Hawking radiation, it's my understanding that Stephen
was using the vacuum fluctuations of SED to imply that both
particles come into being, one gets sucked into the BH, and
the other is given off as Hawking radiation. There is nothing
special about the event horizon in creating matter and anti-
matter particles... the SED vacuum fluctuations theoretically
take place in *every* cc of space...

....to include the cc right under our noses. g

happy days and...
starry starry nights!

Gaia shadow come November,
Does this bode well for December?
Moon aglow as I remember,
Tremble, tremble glowing ember,
Seems my life's a severed member.
