... gravity and magnetic fields exists. By doing this the universal theory is again given a morsel of reality with respect to existing laws. Everybody have a merry Xmas. And try not to be overbearing to those gathered around you Art I find it interesting so many "speak" of gravity as a "pulling force" when, in all actuality, it is a "pushing force" ... The earth is like a "bubble" in a "liquid ether", just like a bubble of air in water, the water is a force applying pressure to the bubble--but then, it is all how you look at it ... Regards, JS |

Certain physical theorists have hypothesised that this might be because we only see one aspect of gravity in our three/four (take your pick) dimensional universe. At any substantial physical distance from a point, gravitational force exerted per unit area is generally the largest force observed. Gravity interacts relatively weakly with matter and even less with the other three forces, so I would expect that any effect would be at the limits of measurement, even with high transmitter powers. Certain 'fringe experimental' groups claim to have found evidence of a reduction in gravitational attraction in the presence of rotating, high powered electromagnetic fields. This would appear to form the basis of proposed 'practical' flying saucer designs by such groups. Some conventional scientifically monitored experiments have shown apparent slight reductions in gravitational attraction, but whether the effect is real, or the measuring instruments were affected in some way by the presence of extreme electromagnetic fields is a moot point. Most of the proposed designs seem to require rather elaborate and expensive, large structures to be built to create the required fields. I think we can all see where this might be leading... When the additional 'hidden' dimensions demanded by string theory are factored in, it is entirely possible (even probable) for such effects to occur but not necessarily on a humanly observable scale. Gravity may seem to be the weakest force here on earth, but at cosmic scales it rules supreme. Mike G0ULI |

Hi Mike, Without pursuing the other three (you may resolve this in response), the force of gravity is inversely proportional to the square of the distance between those bodies being acted upon. This is the same relation to radiated power (in this case 100W) and the same two bodies (if we are doing substitutions) if they are located in the far field. In the near field, the force of radiation varies to the third power, and in the very close field this power is substantial: if that remote body is resonant, and in that near field, then it can absorb at least half of that power or more. Unfortunately, those who want to hoist Newton's corpse on their shoulders for a parade celebrating their powers of insight; they cannot offer that gravity is tweaked even by a thousandth part - and a thousandth part is easily measured. ... At any substantial physical distance from a point, gravitational force exerted per unit area is generally the largest force observed. This is, no doubt, a reference to nuclear forces where electric and magnetic dominate in geometries larger than a bacteria. Perhaps Arthur's levitating particles that dance to RF and leap off the antenna are fried virii. Unfortunately, for Arthur's levitating particles, the RF would have to be tuned to several thousand THz. (Art, a sunlamp would do the same thing cheaper.) ...Gravity may seem to be the weakest force here on earth I dare say that any subjective test of that would invert the "sense" of your statement. , but at cosmic scales it rules supreme. The human response aside, at cosmic scales you have cosmic mass in relation to less than cosmic scale. That is, comparing two galaxies' gravities is necessarily heavily leveraged with billions of suns, and yet the distance between the two centers (of galaxies) is probably on the order of 100's to 1000's of either galaxy's radius. Newton would shrug that off as being unremarkable - still only square law stuff. Newton would probably have expressed the force within 20% on the first pass. Push those two galactic systems to the edges of the cosmos will only reduce that force by the square law (it certainly won't increase it). However, none of this answers how gravity can be an all band antenna's friend as much as Arthur would like to have them wed. 73's Richard Clark, KB7QHC |

My understanding is that it only takes a moderate magnetic field to levitate a free electron, which is a world of difference from what you are saying Art However, none of this answers how gravity can be an all band antenna's friend as much as Arthur would like to have them wed. 73's Richard Clark, KB7QHC |

All you have to go on are books. Let's just take one very simple example about magnetic fields and electrons: The Magnetron! Do you know what's in a Magnetron? I doubt it. You will have to look it up in one of your books, whereas I've held on in my hands while servicing a transmitter. So, already knowing you haven't got a clue about what is in a Magnetron, then I will tell you. Cathode, Anode, and Magnet - nothing else to get in the way. So, there you have your magnet, and it is whopping big one too with a whopping bloody field that goes waaaaaaaay beyond what you call moderate (moderate is about 12 orders of magnitude toooooo small in comparison!). Does this magnet rip electrons right out of the metal? It would rip apart the metal first before that happened. And yet electrons fly from Cathode to Anode ONLY when the Cathode is HEATED! What is more, the magnet is utterly unnecessary for those electrons to flow. Ever wonder why Cathodes (or filaments) are heated? Well, in this case (as in all other cases) because the Magnet doesn't have the oomph to pull the electrons off the cold, cold Cathode. If a magnet can't do it, electrons are certainly not going to jump off an antenna - not unless there is sufficient potential to cause corona. Even then they don't go very far - not even a foot. Corona doesn't measurably add to DX unless you are at sea signaling by semaphore. Now, can you tell us what a "work function" is? If you could, then this nonsense about levitating electrons would collapse. I will give you a week to do your research. :-) 73's Richard Clark, KB7QHC |

Mike G0ULI this is because there is LOTS of matter in the universe. while each little piece of matter creates a weak field when you add them all up it creates a large field. As a sidelight, there is (at least as far as we know so far) no, 'negative' pole of gravity... that is, every piece of matter equally attracts every other piece. with electric fields or magnetic fields, there are opposite polarities that tend to mask each other (superposition anyone???). so while you could get higher forces with less electric charge, separating them takes more work and the farther away you get the separated charges tend to hide each other so the field falls off faster. it is also hard to clump lots of the same charge together in one place to create a large force since like charges repel each other. |
