Hi Eric oc,and Painius. We seem to talk very easy about "magnetic lines
of force" Do we really know what we are talking about? What is the structure(particle,or wave) that creates these force lines? How fast do they travel? Earth's magnetic field changes polarity (why) Why does the Earth's magnetic field move(say about 100 miles? I have thought about this for many moons,and in my minds eye have answers to these hard questions. Some I even like. All are better than no answer. Bert |

Question for Eric Crew:
It can be assumed that you and LK ascribe to the void-space premise, right? oc Anti-spam address: oldcoot88atwebtv.net Change 'at' to@ |

Congratulations! I was thinking... since the temperature issue seems to be crucial to mainstream acceptance of LKs ideas, can it not be shown that temperatures of the Sun, both coronal and surface, must be lower than believed or else Mercury would be long since vaporized, while Venus, Earth and such would be so much hotter than they are? The 'conventional' idea is that although the temperature of the corona is supposed to be millions of degrees the atmosphere is so rarefied that the amount of heat (proportional to mass density times temperature) is relatively small and the heat received at Mercury for example is not nearly enough to cause it to melt. The flow of heat from the corona would soon cool it to a much lower temperature after a few hundred miles. The theories claiming these multi-million degree temperatures are not convincing and LK's claim that the nuclear reactions of recombination of protons and electrons cause the indications of very high temperatures conforms more to accepted physics. Incidentally the streams of electrons inside a television tube only cause a small rise in temperature of the tube. LK's ideas mainly concern the effect of temperature on the velocity of the particles in the solar interior as a result of the heating effect of the nuclear reactions. This causes electrons to travel at about 40 times the velocity of the much more massive protons, causing electrical charge separation and explains the many processes in the Sun and the surrounding atmosphere. There is no need to assume a dynamo producing powerful magnetic fields, etc. IOW, can we not use the surface temperatures of Earth, Venus, Mars and Mercury to infer a maximum possible temperature at the source that is being radiated toward them? I could be wrong, but it just seems to me that the temperatures which scientists attribute to the Sun would still be quite high even after traveling millions of miles... much higher than they actually are. No point in discussing this when LK's ideas give a rational scientific solution to the "high temperature question". The discovery of the large number of filamentary discharges show that these are electrical and their magnetic field is the cause of the small diameter of the filaments Heated plasma streams do not have these characteristics. Quick question (excuse me) Can you briefly explain how such a strong gravitational field as the sun produces a rarified atmosphere. I always assumed that the sun's atmosphere was very dense. Jim G |

Hi Panius,and Eric Crew We could add still another reason why there
is life on Earth. The radiation leaving the sun's core takes 100,000 years before it reaches the sun's surface. Instead of being all gamma photons hitting the Earth we have a mixture of photons(white light) PBS NOVA did a nice job last night explaining how harmful gamma rays are. Bert |

Jim Greenfield asked:
Can you briefly explain how such a strong gravitational field as the sun produces a rarified atmosphere. I always assumed that the sun's atmosphere was very dense. The Sun consists entirely of hot gas. The density of the gas decreases smoothly from the center outward. Because the gas is hot and ionized it is only semi-transparent. What we call the "surface" of the Sun is actually just the depth into the gas from which light is able to get through all the semi-transparent gas above it to reach our eyes and cameras. Deep down it is extremely dense. Far out it is extremely rarified. There is no discontinuity between the two, as there is on the Earth, where the gaseous atmosphere is sitting on top of a solid and liquid surface. -- Jeff, in Minneapolis .. |
