I think the strongest force holding crystals together is usually electric charge. Positive vharged ions and negative-charged ions hold each other in place by their attraction. Some molecules do a sort of sharing, they each get the electron part of the time and they don't jhave time to drift off before it returns and leaves again. The biggest thing holding liquid water together is hydrogen bonding. Hydrogen gives its electron to oxygen and gets it back part of the time, but when the molecules are packed close together it usually isn't clear which oxygen it will give its electron to next. Which one is the real molecule? They're sort of stuck together until that's decided. They tend to stay away from other liquids or gases that don't let them do that -- we all that process "surface tension". They do break away some though, until they reach an equilibrium between water molecules leaving and others coming back. With gravity the water collects somewhere and sits there with only the top surface exposed to air. Inside a closed container the water will reach equilibrium, otherwise it will keep evaporating away when the humidity is less than 100%, until it's all gone or a rainstorm adds more water to the container. The air stays around because of gravity though it does very slowly leak away into the vacuum. Without gravity the air would wander off, and the air pressure would drop so the water would evaporate faster and then boil away, and it wouldn't be approaching equilibrium with air in a closed container or with air that can reach equilibrium at STP, it would be approaching equilibrium with the vacuum of space. So I think you would mostly get liquid water inside closed containers. But there might be open structures that would contain enough water at enough pressure that it made liquid water somehow. I can't say much about how that would happen. I don't know enough about stars to decide whether there might be a way to get a star without gravity, and I have no idea what new structures might arise that can't happen now because of gravity.
From: Ahmed Ouahi, Architect on 27 Sep 2009 13:37 For the time being, as it is already feeled as known as everything along the univers, is the relationship along any reaction as along any overeaction, what is all about... However, as all as any particle is a definitely along an endless turning and moving around the univers exactly as the planets are orbiting the sun along an other scale... Therefore, whether along any microspic microcosm behavioral manners, it is this, what it makes the time to be functional matter, as it erase a definitely a space time... However, as is that, also along all the particles and the molecules are along all of them, a definitely the normal as the usual behaviours as some of them are always retracting and being a definitely against one an other... Therefore, something, that let none of them to move further among the others, as it is always up to the one who would get any charge along any electron moving along the road, and this is what is all about, usually as a generally, along that matter, a definitely as a matter a fact... -- Ahmed Ouahi, Architect Best Regards!

Pull enough vacuum, even at extremely cold temperatures, and that strong electrical/electrostatic bond of h2o molecules seems to vanish, even though the original weak force of gravity by rights should still exist if it were based purely upon the given number and mass of all those original h2o atoms/m3. So, what good is the weak force of gravity if it too vanishes at extreme cold and vacuum? At near zero of perhaps 0.1 K and near an absolute vacuum of perhaps 1e-24 bar; how large of diameter is the hydrogen atom? ~ BG

If gravety disapeared, the larger masses, will pull lesser masses at accumulated speeds, equal to escalate turbulance that will form into new masses by random inpact. these formations will form a new universe. I regard Your post as babble, and can only smile at the 5 "stars" has been awarded by a provecator. But to make a point about accumulated speeds: Regarding lightspeed. http://groups.google.co.uk/group/exceeded-lightspeed As supernova explotions or the Big Bang theory implies, matter is thrown by bigger force in various directions and speeds. If some matter is thrown at 2/3 of the speed of light in one direction, and other matter is thrown in oppersit direction at the same speed from origen,- theese will travel apart at 1 1/3 of the speed of light. This tells us travel beyond the speed of light is possible. This also explains why we cannot see app. 90 % of the universe. Dark matter appears to be hyperspace to me. Think of the antiquated rules that led our forfathers to believe that we could not travel beyond the speed of sound. regards Jesper Hjulmand Jorgensen Jorgensen.jesper(a)gmail.com Ps.: Energy equals mass squared minus unknown quantity of deteriation squared. We now from particle-accelerators that neutrons accelerate above the speed of light to find a partner(turning into dark matter). Electricity is working at lightspeed in controled leeds.
