   The planetes and stars couldn't fall, they wouldn't be propelled...how could the planetes stay in place? No magnitism, no gravity, no pressure?  There could be no explosions, no ice, what would happen?  Would time stand still, or stop, and we suddenly become a cosmic mural???

   Well for starters time is a man made thing so it would only stop if man was no more,and for the theory of what would happen,we would go flying into outer space,and that is as fast as the world is turning,who cares about the numbers,we would fly till we crashed into another spinning out of controlled object.

   Big things would go in straight lines. By big things I mean things bigger than the atomic scale. We would leave the planet unless we hung onto something. But the atmosphere would leave too, and all the water, so there wouldn't be a lot of point hanging around. Trains and boats and planes would all fly. Every hit in cricket would be a six. No-one would need an uplift bra. Synchronised swimming would be illegal. Apart from that short list, nothing much would change

   If gravity dissipated to nothingness, everything else wouldn't. That's right, it wouldn't. The hydrogen atoms that are attracted to the oxygen atoms, of which your body is made of a large percentage, would simply stay put - attached to one another. So would EVERYTHING else.
   
   We would enter into what could become known as "The Huge Freeze" (the opposite of "The Big Bang.") Nothing would move and we (along with the rest of the universe) would simply cease to exist. With no gravity, there would be nothing to make anything move (life - way beyond simple human life)...
   
   ... well except anti-gravity (science fiction.)
   
   All that would be pending that gravity ceased to exist quickly enough. If it ceased to exist too fast, everything... EVERYTHING would be torn apart and the create the reverse, which would simply create gravity again. Everything would then be opposite of how we know it. Feet would be heads; shoulders would be ankles; knees would be hips. Even frowns would be smiles!
   
   think about it...

    In fact, the first part of my answer was entirely serious - big things would go in straight lines. Newton's laws would still apply, so although the planets would no longer be attracted to the sun, they would still be moving. They would leave their orbit tangentially and fly off into space. The earth would continue to spin, but would disintegrate. The atmosphere, waters, desert sands, topsoil - everything that is presently held by gravity - would simply fly away.
    
    Though we wouldn't be around to see it, Black Holes which account for a high proportion of the total mass of the universe would 'explode', dispersing their captured contents into space.

       I dont understand why you would not believe in their excistance.  Actually a black hole is at the center of most galaxies,  Perhaps what you mean is that you are not sure what they are made of.   Since the term Black Hole is simply a metaphor anyway.   
       
       What we really don't know is what they are, they certainly do excist though.   Am I making sense to you.
       
       By the way the gravatational pull of a black is the strongest we know of.   Looking at a spiral galaxie such as the Milky Way the gravitational pull is stronger towards the center.   Thinking of this as water going down a toilet.   Common sense would tell you the water or stars (suns) towards the center would be traveling faster correct.
       
       Well it has been recently discovered that the stars closer to the center (Black Hole) of our Milky Way are traveling the same speed as the stars on the outer edge of the galaxie itself.
       
       This took a few good scientists studying a few small areas of our Galaxie over 10 years to prove this theory.
       
       I am so very thankful to people like that.  To devote their lives to discovering and learning for generations to come.

       Why? without gravity there would be no 'weight' by definition, but mass would be unchanged. It would still require a force to change the (relative) motion of any body. There would be no reason for things to stop moving. Not that it's about to happen...

    If gravity suddenly disappeared, the following would happen almost immediately:
    
    1. the earth would no longer orbit the sun. Instead it would continue in a straight trajectory starting from the point it occupied when gravity disappeared. This is because the sun would no longer be exerting gravity on the earth and causing it to fall towards the sun in its orbit
    
    2. the moon would wander off in the same way. It is possible that the earth and the moon would collide depending on their relative positions and trajectories when gravity disappeared.
    
    3. the atmosphere and water etc would quickly fly off into space. For a time, the atmosphere would stay with the earth because most of the atmosphere would be travelling in the same relative direction and the same relative speed as the earth, but because air molecules also bounce around and are affected by heat, a growing number would fly off into space leaving the earth airless very quickly. The result is that we would be like the moon, which is without an atmosphere because its gravity is too weak to maintain one
    
    4. the Sun would bling out. Currently the fusion reaction which lights the sun is maintained because the gasses are compressed to an unbelievable extent at the core of the sun. Without gravity, there would be insufficient pressure to maintain an atomic reaction. The existing solar bursts would cause huge parts of the sun to be blown away and some of these chunks might reach the earth and vaporise us
    
    5. we would be dead.

    Hmmm....interesting thought experiment.  It's made tougher, of course, considering that we don't know what most of the Universe is made of and how all the dispirit parts work together.  The fact that we don't really understand gravity well at all doesn't help matters.  Even so, let us proceed anyway.
    
    First, we need to establish what we mean by gravity.  For the sake of argument, we can say that it is a weak attractive force whose effects become observably large over macro scales.  In our ordinary experience it behaves much like opposite poles of magnets, attracting one object to another.  On larger scales, it is described as deformations in spacetime, but the attractive effect is similar.
    
    What happens if, all of a sudden, all gravity disappears?  The most obvious effect to us is the chaos that results when all moving, and especially all rotating, celestial bodies divest themselves of all matter whose inertia exceeds the now absent attractive force of gravity.  Basically, everything not otherwise held together by the other universal forces or chemical bonds would just keep traveling on its own merry way in a straight line in the direction it was moving when the pull went bye-bye...i.e., everything flies apart into chunky pieces of matter.  Initially this would be very messy as a lot of non-gravitational processes effected by this deconstruction will release a fair amount of energy.  Stars would go nova.  Planets would smithereen.  Galaxies and clusters of galaxies would lose their form.  Perhaps most profoundly, "up" and "down" would no longer exist anywhere except as quarks.
    
    Slowly, the energy dissipates, matter pieces collide and fracture, atoms decay, and the entropy of the Universe increases eventually resulting in a cold Universe filled with a fog of subatomic particles.  What happens then...I'll leave that for a later debate.
    
    This self destruction could be amazingly impressive to watch as those bodies that manifest gravitational effects the most: neutron stars, quark stars, black holes, etc.; have their reality state profoundly altered.
    
    But I'm sure things like dark matter, dark energy, antimatter, and other exotic items in the Universal menu would have something to say about all of this.

    My problem with black holes is this: 'gravitational field is so powerful that nothing, not even light, can escape its pull after having fallen past its event horizon.' Apparently the theory is - can't see it cause no light is emitted. To my mind where no light is emitted there should be seen a black hole. Nothing else can be there since it is all sucked in. It should be empty space and impossible not to see. If the gravity of the sun holds the solar system together, then one notices that galaxies have garganguan
    solar masses.

         I think the thoery is that even black holes emit some sort of partical because it also emits radiation or has a heat signature, and that a black hole generates it's own force of gravity like stars millions of light years away. 
       
       Now I am not entirely sure, but the perfect circular shape has it's own properties that generate energy, by it's own forces it can freely roam the Universe without needing an exterior force to move it.

       Maybe all those black holes that we see are really just the remains of prior evolved non terran civilizations that built devices that recreated singularities and ended up destroying their civilizations/planets in the process by accident, (like the device we are building right now in Europe for that exact same purpose).

    Black holes are interesting things.  I, too, once thought that they would be easy to see as the absence of light would be a tell-tale sign.  But just as when a blob of freshly chewed gum dropped on beach sand leaves you seeing a blob of sand and not gum, all of the stuff that gets attracted to the black hole pretty much obscures the black hole itself.
    
    Then you have the side-effects...like the X-rays that get produced when things get accelerated into the black hole...and fun stuff like that.  Makes them even that much easier to spot, when when the thing you can't see can't be seen.  Sort of.

    Einstein was a statist. Then he converted. Very dissapointing.
    All they got for the expanding universe is 'red light shift', meaning longer light wave shifts, losing energy, moving away. Losing energy could come from a long voyage through space or just represent older age stars or quasars, not flying away. At any rate they can't make the observations fit the theory, so to explain the contradictions they have to create ever more exoltic models like black holes and dark matter.

    The ironic part about this discussion is that as physical forces go, gravity is pretty wimpy. Physicists speculate there are multiple universes, and the there is another universe that is replete with gravity. Our gravity, they theorize, is the tiny amount of gravity that can leak through from that universe to our own.
