Gravitons have to carry spacetime into the quantum realm. So when they stop doing that... But of course, you know everything, and are just a sniper anyway... David A. Smith

Try this physics-101 analogy out for size: When water is exposed to the lunar environment, and especially on the daytime heated portion thats so physically dark, regardless of whatever self imposed gravity or Newtonian binding force that may or may not exist between molecules of h2o, whereas those individual molecules of h2o will quickly become purely individual atoms of hydrogen and oxygen before those too seem to vanish by breaking down into subatomic particles that are rather easily associated with other particles and/or summarily blown away by our solar wind because of insufficient local gravity and obviously too little pressure. At the Selene/moon L1 is where the extreme vacuum of that Zero Delta-V location is likely worth 3e-21 bar or less (a millionth the pressure of what the lunar surface has to offer) thats always assisted by the continuous 2e20 N/sec of tidal force . Too bad that after a half century and counting, we still have nothing of any science platform interactively situated within that nifty and easily established location.

Sanny, most everything in existence is either paramagnetic or diamagnetic (including frogs and most every other known form of biodiversity), and otherwise the Newtonian force of gravity or molecular binding force is actually extremely weak, whereas the electric force is always hugely more powerful. This extremely weak force of gravity needs a little help from those other much stronger forces, including pressure. Without pressure is where liquid or fluid forms of matter can not coexist. In other words, the vacuum of space is for solids that cant easily evaporate or sublime, and just because water can be made cold enough to form ice doesnt count as a solid unless theres extreme cold and pressure of perhaps at least 3e-5 bar (our moon is supposedly 3e-15 bar, so theres no chance of raw/naked surface ice that isnt shielded from that extreme vacuum, though a few meters of that fluffy crystal dry and electrostatic charged soil/dust might be a sufficient shield). Try this physics-101 analogy out for size: When any volume of water is exposed to the lunar environment, and especially on the daytime heated portion thats so physically dark as coal, regardless of whatever local or self imposed gravity of Newtonian molecular binding force that may or may not exist between those molecules of h2o, whereas these individual molecules (every last one of them) will quickly/instantly vaporize and become purely individual atoms of hydrogen and oxygen (no chance of their forming into raw ice or remaining as liquid), shortly thereafter those atoms too will seem to vanish into less than thin air by further breaking down into subatomic particles that are rather easily associated with all those other solar wind and cosmic particles that usually far exceed the lunar escape velocity by at least 100<10000 fold, and thereby each and every conceivable molecule of h2o gets summarily blown/extracted away by the persistent flux of our solar and cosmic winds, all because of the insufficient local and whatever molecular gravity, as well as theres obviously way too little surrounding pressure at 3e-15 bar. Within our Selene/moon L1 is where the extreme vacuum of that nifty Zero Delta-V location is likely worth 3e-21 bar or less (a millionth the pressure of what the lunar surface has to offer), thats always assisted by the continuous 2e20 N/sec of tidal force. Obviously theres always the passing solar and cosmic flux thats continually populating this nearby Zero Delta-V location. If the Newtonian tidal force from Earth didnt exist, and given that same L1 distance from the moon (roughly 34r) would only realize a pressure of 2.6e-18 bar, however with the Newtonian force from Earth should make that 2.6e-21 bar. Also interesting to note, is if the moon were larger and had the same mass as Earth, except w/o any geomagnetic protective field, as such would only amount to a surface atmospheric pressure of 1.81e-14 bar id only that weak force of gravity were responsible. Too bad that after a spendy and inflationary half century and counting, we still havent accomplished any science platform as interactively situated within that absolutely nifty and easily established earth-moon L1 (Selene L1) location.

From: chazwin on 24 Oct 2009 13:44 There is no gravity but the property of matter whereby it is attracted to itself. To remove gravity is to remove matter, to remove matter is to remove the relation of matter to other bits of matter: space itself. Result nothing

What does DNA/RNA know or care about gravity? What does a molecule of water care about gravity? Water on Earth doesn't materialize as we know it only because of gravity. ~ BG |
