In a normal electric field. Only virtual electron-positron is
produced. No virtual proton-antiproton pair is produced. How come?
Is it because there is not enough energy to produced proton-antiproton
pair in the normal electric field (from electron)??

that is solved all th e entanglement

Y. Photon has no mass. That is why it can travel at c.
Anything with mass travel less than c. What is your arguments
and proofs that photon has mass?
|
The theory is that the photon has no mass. AFAIK the
measurements of photon rest mass have established an upper
bound of about 2 * 10^-16 eV. (This is not to be confused
with the *energy* of a photon, which for a 500 nm visibile
light quanta is about 2.4814 eV. Naively dividing this
by c^2 results in a "pseudo-mass" of 2.757 * 10^-17 eV
s^2/m^2; the problem here is that the units are wrong.)
http://arxiv.org/abs/hep-ph/0306245
cites this result but suggests it is destroyed by vortices; I can't
say, but this is from the result of a Google search.

Re: Pair Productions Questions

there are too many arguments
one general is
tha t once you internalise it
a lot of artificial 'problems' that he false assumption (of no mass..)
created
are magically solved!!
you just have to understans that :
THE PHOTON IS AN EXCEPTION TO THE ABOVE RULE!!
that n omass can reach th evelocity of C
btw was it Einsteins claim that th ephotn has no mass or was it
of his folowers??)
once you realse that
energy i s mass in motion (exactly as in macrocosm!!!!!)
anhyone who is chnging the macroscopic rules
the burdain of prove are - on him !!
you can expand macroscopic rules
you cannot abort them
i hope you realise the difference between expanding a rule
and aborting it .
so if you get it
than all those enigmas of swiching betwen energy and mass
are solves imediately !!
and there are other argumements
that if you accept my word untill now we can go on with it

Conservation of momentum.
Wrong.
The photon has spin in one plane. It
is two-dimensional.
You bring it in close in order to spin it
in the second plane.
This makes it three-dimensional.
Momentum plus a healthy amount of
spin is changed into an electron and positron.

Utter nonsense.
Hint to "Patti": Sefton is one of our many resident cranks. Simply
ignore him.

Porat your stuff is pretty hard to read anyway but on top of that you |
are mixed up. The quotation "Particle are..." is not mine, it's
Bjoern's QED stuff to which I am objecting.
Look at my paper on Permittivity where I derive how it is possible
even to store energy in a vacuum. And there you will finally find the
seeds of everything in the universe, each "seed" containing an ep pair
in a shell 3.54x10^-14m.
That pair is what responds to a vacuum electric field like a
sqeezebox, each particle moving oppositely and elastically, storing
the electric energy in the "spring".

no forces without matter thats right
it ios because
th eforce agents are residuals of matter
if you like methaphorically:
splashes ' from the matter
so if there is just vacum nothing can come out of it!!
