Dina put me on ignore if you find my hreads so painful.
The Sun Over an hundred years ago “we” had no idea what powers the sun. Residual heat, of the sort ascribed the earth’s core, was clearly out of the question. Then Radio-Activity was discovered. But the idea that the sun was full of radium or other radioactive materials was scotched when research in the 1940’s showed that a nuclear pile will go critical with very small amounts of radio-active material. The idea that the sun is a nuclear fission device that splits atoms was shelved. A decade later, the Hydrogen Bomb was invented. In the meantime (and since before the history of man) the sun is continuously putting out radiation is a very small window. Over 98% of this window is infra-red spectrum through “visible” heat (light) to ultra-violet. About 50% of the solar output is the rainbow of visible radiation. Not a bad guess for the gods of evolution was it, to place a nuclear furnace so close to us; and it only puts out safe radiation? Wavelengths exactly in between x-rays and microwaves. With a margin for error that is neatly catered for by the earth’s natural production of ozone –which is itself another miracle. Alternatively, if you don’t believe in miracles: No one has yet discerned the mechanism by which a solar system derives its heat and light. The bible states, categorically, that the sun will go on shining as brightly as ever; to time indefinite. Whether “time indefinite” means forever or not, this term rules out nuclear fusion or fission (as far as we understand it) and any other physical / chemical “one way” reaction; just as previously it ruled out glowing coals. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

Alternatively, if you don’t believe in miracles: No one has yet discerned the mechanism by which a solar system derives its heat and light. Bull****. Clueless, as well as bigoted.

Got a better explanation than thermonuclear fusion? Thought not. Go away till you have one. -- Lt. General, Fanatic Legions. Commander of Southern Hemisphere Forces.

The Sun's primary energy source is the p-p chain whereby helium is fused from hydrogen in the core of our sun.

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; http://www.aip.org/enews/physnews/20...t/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 http://www.aip.org/enews/physnews/20...it/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 www.aip.org/physnews/update. 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/20...it/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.

It would be criminal to leave someone in such ignorance without at least attempting to bring some light into their, possibly self-imposed, darkness. The Sun SNIP In the meantime (and since before the history of man) the sun is continuously putting out radiation is a very small window. Over 98% of this window is infra-red spectrum through "visible" heat (light) to ultra-violet. About 50% of the solar output is the rainbow of visible radiation.

With a margin for error that is neatly catered for by the earth's natural production of ozone -which is itself another miracle. This seems a bit like the twaddle that comes from organisations like "Answers in Genesis". While it may sound attractive to your obvious fundamentalist leaning, it is inaccurate. Do you know what skin cancer is and what the primary cause for it is? That primary cause is, you guessed it, the sun. That kills your "safe" claim. Now have a look at this page http://www.lofar.org/science/urd100/Solar_both.html and see what frequency ranges these people are using to study the sun. As you will see, it is well below the microwave range. So much for your miracle. Just another minor point. If evolution is active, it stands to reason that organisms that can survive in the environment here will survive and prosper. Further it should come at no suprise that the eye is most sensitive to the emissions put out by the sun, since that it what is available for it to "see" with. Nor should it be a suprise that it reacts to those wavelegths that can provide sufficent chemical activity to be detectable. What would be a miracle is if we didn't use what nature provides. Alternatively, if you don't believe in miracles: Miracles are stuff of every religion, not just Christianity. Which god (or gods) cause them, if they exist at all, is debatable, so the Bible cannot be taken as an authorative source for scientific research. There is a multitude of religious books offering conflicting accounts of how the world was created and its ultimate fate, each devotee thinking that account is the "truth". SNIP Whether "time indefinite" means forever or not, this term rules out nuclear fusion or fission (as far as we understand it) and any other physical / chemical "one way" reaction; just as previously it ruled out glowing coals. It may rule out these methods as you understand them, but that is not the case for others. Given the expected life of the sun using current models, I think the term "to time indefinate" fits pretty well for a species whose longest lived human, even including the alleged Methulsa, is the minutest fraction of the time it has been shining and is expected to shine. Read this fundamentalism stuff if you wish. However, it has been my experience that they have a strong disposition to misquote in an attempt to bend the facts to their theories or to complely disregard what does not suit their position. If you wish to be taken seriously, I suggest you read the current research and then argue where it is wrong. Mark |

Why you should concern yourself with that is beyond me. Still, each to his own, eh? Concerning skin cancer: I believe that problem was covered early on in Genesis.

You think that our present inability to produce sustainable nuclear fusion on Earth (largely a problem of containment) somehow casts doubt on fusion as the mechanism which fuels the stars? Just to make things absolutely clear: you believe that the Sun will shine forever because it is shining out of God's arse? Did I get that right? -- Pyriform |

I can't wait until a fusion reaction is set up that gives off more power than it costs. Ever heard of the Hydrogen Bomb? That is why it makes such a big BOOM! (from Fox News) "In a typical hydrogen bomb, the detonation of a fission bomb compresses and heats a core of lithium deuteride, lithium combied with the hydrogen isotope deuterium. The neutrons emitted by the fission reaction strike the lithium atoms, creating atoms of another hydrogen isotope, tritium. The heat of the fission reaction begins to fuse the tritium and deuterium atoms, creating helium along with a large amount of neutrons. The neutrons created by both the fission and fusion reactions strike a specially shaped uranium casing, which begins to undergo a fission reaction of its own, creating still more neutrons, accelerating the fusion reaction until it all culminates in an enormous explosion." All this effort creates a weapon that exceeds the power of the fission bomb (otherwise there is no point in making all that effort), hence it liberates more energy than it took to create the fusion. Your wait has been over for many, many years. I think you perhaps you mean " a *controlled* fusion reaction is set up that gives off more power than it costs." This is more elusive. In the case of the sun, the priming fission bomb is not required, since gravitional collapse provides the energy required to start the reaction. Let me know when they replicate a fusion reaction that produces radiation that corresponds with the sun's spetrum. That'd be a cool trick. Is this before or after you find out that the Hydrogen Bomb works? A biblical one too (Just thought I'd throw that one in for the dullards in sci.geo.earthquakes. Oh I'm so good I laugh at myself!) So you should. Everyone is laughing at you as well. ;-) Mark |
