![]() "Brad Guth" wrote in message om... "Is the moon leaving, or are we shrinking" Whatever you do, don't ask the likes of David Helfand, as you might be unpleasantly surprised at his response. I believe this supposed recession rate from Earth (cm/yr) of 3.8 is rather insignificant, at least until we calculate upon what that represents, into the amount of added speed and/or thrust needed for the task. Brad, the mechanisms for the lunar recession have been well understood for decades. In a nutshell, tides cause friction between the oceans and the ocean floors, which transfers energy from the solid part of the earth to the oceans. One of the effects of this friction is that the tidal bulge is off-center, and is located "eastward" of the moon. (So the high tide actually occurs when the moon is west of overhead.) The result of the tidal bulge being off center is that there is a torgue effect placed on the moon, and this in turn transfers energy from the earth to the moon. The earth's spin rate slows, the moon is speeded in its orbit and therefor moves further away from the earth. (This transfer of energy is essentially a transfer of angular momentum, which is a conserved quantity.) The historical (over geological eras) rate of recession has varied due to varying amounts of tidal friction due to shallower or deeper oceans, and the positions of the continents. http://www.talkorigins.org/faqs/moonrec.html has a nice discussion of the whole topic. |

Thanks so much, as what you've explained is certainly a whole lot more believable than all the other flak I've received. I'll do some further research and see if I can discover upon the actual amount of said recession energy, in relationship to what a dipole tether arrangement could possibly extract. Being that the LSE-CM/ISS offers an unlimited opportunity for such a tether dipole, this is where I believe there's a great deal of energy to being had, subsequently stored within those counter-rotating flywheels. BTW; does this lunar recession argument represent that Earth is moving away from the sun? Or that any other moons are moving away from their planets?

Regards, Brad Guth / IEIS~GASA Perhaps you're absolutely right, just like Jay Windley seems to never get my point. Here's a little feedback from: Jay Windley ) "High-energy cosmic rays do not come from the sun. They come from outside the solar system, and our sun is the primary defense against them. The particles released by the sun itself are of considerably lower energy and thus their secondary effects in the ambient are minimal." Fortunately, I never specified upon any specific "high-energy cosmic rays", just pointing out that our sun is certainly capable of tossing out its fair share of far worse things than visible photons plus IR worth of BTUs and of those nasty UVs. Obviously a supernova is worth a thousand fold in terms of being nasty, thereby from the far off generated galactic influx must offer a measurable degree of such, and of the secondary radiation given off by all that infamous clumping lunar dirt should become a fairly darn good indicator. The assertions or premise offered by Jay Windley, that of not only lacking an atmosphere but also without a Van Allen buffer zone is not such a bad thing if you're out and about on the lunar surface, seems somewhat risky if not downright lethal. I might have come into that understanding if we're referring to an earthshine illuminated lunar surface, but not so far if that's of any fully solar illuminated environment while wearing a moon suit because, we're not talking about avoiding a 270 nm UV sun burn. Sorry about all my reverse engineering logic, or lack thereof. I was simply trying to establish upon the amount of solar radiation that becomes hard X-Ray class. "High-energy cosmic rays do not come from the sun" Do we suppose that happens to include the likes of the last couple of weeks of solar flak? Seems there should be some specific knowledge (excluding Apollo) of what's what pertaining to the solar illuminated surface as opposed to the absolute lunar nighttime environment and, of something specific pertaining to whatever earthshine contributes. This is somewhat like getting a grasp upon the applied energy (thrust) involved in accelerating something the size and mass of the moon. As the feedback provided from: Ami Silberman ) "The mechanisms for the lunar recession have been well understood for decades. In a nutshell, tides cause friction between the oceans and the ocean floors, which transfers energy from the solid part of the earth to the oceans. One of the effects of this friction is that the tidal bulge is off-center, and is located "eastward" of the moon. (So the high tide actually occurs when the moon is west of overhead.) The result of the tidal bulge being off center is that there is a torgue effect placed on the moon, and this in turn transfers energy from the earth to the moon.

(This transfer of energy is essentially a transfer of angular momentum, which is a conserved quantity.) The historical (over geological eras) rate of recession has varied due to varying amounts of tidal friction due to shallower or deeper oceans, and the positions of the continents." For the benefit of all my loyal critics, I've conceded that there's a darn good chance that the likes of Tim Thompson has more than a few valid points as to his version of what's what. This following page is just another example of my learning from the pros, of accepting other input, which may even including the likes of what you've just presented, that I'd not be calling flak, as there actually seems to be some considerable worth to at least Tim's version of the lunar recession, if I don't say so myself. http://guthvenus.tripod.com/earth-moon-energy.htm Regards, Brad Guth / IEIS~GASA http://guthvenus.tripod.com |

Pat Probably not but, I'd bet they'd acquire a real taste for human flesh, KFH style, especially of the really dumb and arrogant sort of flesh, since it's more salty.
