Default Strangest Star known is the 'Talk of Astronomy'

Now that's the problem in a nutshell. The P-P process has never been
observed, no once. Not in any experiment in the history of science.
So you presume something that has nothing to do with reality. I think
it was Hans Bethe who invented the process (or at least built a horse
to ride on from its assumptions) and no one has taken him or anyone
else to task on it. When one cannot differentiate the work product of
a so-called scientist from that of a pathological liar then the proper
conclusion is that there is no difference and that science which makes
use of such work products has itself become pathological.


P-P chain energys are observed and now the solar neutrino problem has
been solved.

PHYSICS NEWS UPDATE
The American Institute of Physics Bulletin of Physics News
Number 617 December 13, 2002 by Phillip F. Schewe, Ben Stein, and James
Riordon

PHYSICS STORIES OF 2002. The top two physics stories for the past 12
months were the total accounting of neutrinos from the sun by the Sudbury
Neutrino Observatory (SNO), thus solving the solar neutrino problem (Update
586; www.aip.org/enews/physnews/2002/split/586-1.html); and the formation
and detection of antihydrogen atoms at CERN (Updates 605 and 611,
www.aip.org/enews/physnews/2002/split/605-1.html and
www.aip.org/enews/physnews/2002/split/611-1.html). Other notable physics
developments for the year include stopping and storing light in a solid
(Update 571), the observation of phase-transition behavior in nuclei (572),
publication of some unsent letters by Niels Bohr to Werner Heisenberg (576),
interferometry with C-70 molecules (579), a dispute over "fusion" in
sonoluminescence (579, 599), most precise tests of special relativity (571,
590), sharper maps of the cosmic microwave background (591), "droplet" of
light (596), claims for element 118 retracted (597), verification of the
notion that the second law of thermodynamics can be violated on small
spacetime intervals (598), high precision measurements of CP violation in B
meson decays and in the g-2 factor of the muon (600), scandal at Lucent
(606), record high laboratory magnetic fields (614), polarization in the
cosmic microwave background detected (606), 2002 Nobel prize for physics
(608), noise can improve balance (612), and longest measured atomic lifetime
(616). All the above Update items can be retrieved from our archive at

REACTOR ANTI-NEUTRINO DISAPPEARANCE, measured by a detector in Japan,
supports the idea that neutrinos oscillate from one type to another and that
they possess mass. Nuclear reactors produce several things: heat,
electricity, spent fuel rods, and neutrinos. The neutrinos (or, to be more
exact, electron anti-neutrinos) are a result of fission reactions inside the
reactor core. But some of the electron antineutrinos, once they're underway
and moving through the Earth, manifest one of the weirdest phenomena in all
of physics, namely the ability to exist as a composite of several
sub-species. That is, what we call a neutrino is really several (perhaps
three) neutrinos in one. At any point along its trajectory the generic
neutrino might (if you were to capture it just then) appear as an electron
neutrino, but farther along it might look like a muon neutrino, in which
case it would elude detectors tuned to detect only electron nu's.
The Kamioka Liquid Scintillator Anti-Neutrino Detector (KamLAND) sets out
to sample this odd mode of being. The apparatus, basically a huge reservoir
of optically-active liquid viewed by numerous phototubes, looks for
interactions in which an incoming nu strikes a proton, creating in their
stead a trackable neutron-positron pair. KamLAND resides in an underground
lab beneath Toyama, Japan. It is a sort of telescope peering not at
galaxies in the sky; instead it stares through a block of terrestrial crust
looking for the neutrino warmth cast off by a constellation of 69 reactors
in Japan and Korea.

Taking into account the laws of physics governing the reactions in the
reactor cores, the known power ratings for the reactors, their aggregate
reactor-detector distances, and the duration of the experiment (145 days),
one would expect seeing 86 true events, whereas the actual number was 54.
The researchers conclude that the disappearance of events is due to neutrino
oscillation.

This result is not merely a confirmation of oscillation research carried
out with solar nu's at such detectors as Super Kamiokande in Japan and the
Sudbury Neutrino Observatory (SNO) in Canada (see Update 586,
http://www.aip.org/enews/physnews/2002/split/586-1.html). For one thing
KamLAND studies anti-neutrinos rather than neutrinos. Furthermore, the
production of neutrinos in a reactor is much closer at hand and better
understood than is the case for the sun. The KamLAND finding also serves to
narrow the theoretical explanation of the neutrino's split personality.
