  1. If gravity is the force of attraction between masses, does this force is an intrinsic property of every atoms?

  2. Is there any possibility of some other particles within atom which is yet to be discovered?

  3. Or is it simply a result of cosmic waves which created due to big bang?

  4. Does anyone have any information regarding variations in gravitational force?

  5. If its not there then is it simply be "something like plasma which entire universe in within its plume and huge masses simply accelerate the attraction"?

Gravity is a force exerted not only by every atom but by every elementary particle, every mass in any form, and every energy, including potential energy between elementary particles, and it acts on everything - all forms of energy-mass, too. Experiments prove the "equivalence principle" - the fact that mass is subject to equally strong gravity regardless of the form - with the relative precision of $10^{-16}$ in some situations. Einstein's general relativity describes gravity in terms of a curved spacetime. No "plasma" is involved. –  Luboš Motl Jun 24 '13 at 5:25

  1. It is an intrinsic property of all energy (in Newton's world, it is only an intrinsic property of mass), that includes, electrons, photons, quarks, protons, nuclei, atoms, molecules, toothbrushes, rotting garbage, unclosed sewages, leaking drain pipes, stinky rivers, rotting corpses, mental hospitals, the Original Poster and helpful donkeys.

  2. If we knew what we are to discover in the future, then all discovery would be instant; localised, in time. But most likely, no. Nothing which exists within ordinary atoms (though things like gravitons, supersymmetric particles and the very heavy particles predicted by string theory (an infinite number of them actually) could, eventually).

  3. What? This sounds crackpot.

  4. No. Not until you clarify what you mean. If you are talking about variation of the Gravitational constant throughout spacetime, there are some theories on it, like Dirac's large numbers hypothesis (see wiki link linked to) and some other gravitational theory which replaces $\frac{1}{G}$with a scalar field $\Phi$ instead. I can't rem ember its name and I couldn't find it either. I'll try to remember and tell you later (if I can remember). Edit: Yes, I remembered! It is Brans-Dicke theory.

  5. What? This sounds crackpot. But there is this theory called BEC Vacuum theory which tries to do something very similar (but I don't understand it anyway, I don't even know whether it's considered mainstream or not, so I don't know whether it does exactly that, or not, maybe someone else could help you on that). But anyway, just reading the wiki explanation of this made me doubt its validity.
