Christina Anne Knight proposes the existence of a short range force ( the antigravitational force) which is limited to sub-planck length distances in her new book. It is this force which establishes the minimum size of a discrete unit of space (and renders the existence of singularities impossible).
This means that current ideas about black hole structure and the structure of the universe at the Big Bang are wrong. More issues relating to this subject are discussed within this book (including how an unstable relationship between the gravitational and antigravitational forces is responsible for the perpetual cyclic expansion and contraction of the universe and for the evolution of cosmic parameters). In addition, it is this unstable relationship between these oppositional gravitational forces which produces a cosmic thermodynamic gradient which is reduced during the expansion phase of the cosmic cycle (and is responsible for all of the complexity we see around us).
Anything with mass include you and me do exert gravitational force but the earth is massive so it exert more force than any of any small object including us on earth. The gravitational force is done between two mass in following general gravitational law by Newton. F = G.M1m2/R2 We sum up G.M1/R2 as gravity = 9.81 m/s2 for M1 is earth and R = earth radius Between 2 man with m1 and m2 respectively, gravitational force between these two man is at F = G.m1m2/L2 where L = distance between center of mass (you and me for instance). Gravitational force is small compare to earth's gravitational force but it does exist.
There is no minimum mass at which point an object (celestial or otherwise) begins to have a gravitational force. Any object with mass has an associated gravitational force. The magnitude of that force is proportional to to the mass of the object - lots of mass results in lots of gravitational force; little masses result in only little gravitational force.
Gravitational force should exist between ANY pair of particles; but for individual particles, this force is extremely weak. It is the cumulative effect of lots of particles attracting each other that causes an enormous force between you and Earth, Sun and Earth, etc.Gravitational force should exist between ANY pair of particles; but for individual particles, this force is extremely weak.

Here is the formula for the strength of the gravitational force: F = G m1m2/R2 'm1' and 'm2' are the masses of the two objects attracting each other, and 'R' is the distance between them. There's nothing in the formula that says "Only as far out as this maximum distance". The gravitational force between two objects extends to any distance you want to think about, and past it. It becomes weaker as the distance grows, but it never shrinks to zero, no matter how far apart the objects are. There is a force of gravity between a grain of sand on the farthest planet orbiting the farthest star in the farthest galaxy, if any of them exist, and your pinky fingernail.
mass is a characterstic property of any matter if a matter exits it must have mass by which it is pulled towards centre of earth bt gravitational force is a kind of attractive force which acts btween centre of mass of 2 or more masses
Yes.
Technically, a gravitational force exists between ANY two bodies with mass. This would include a force between your body and any given star in the sky. The force may be small, but technically it's there.
No, there is no mass there to have any gravitational force.
force of gravity is d gravitational force of earth but gravitational force is force of attraction for any heavenly body
yes, any thing above the earth's surface has gravitational force as it can fall
The gravitic force on any object on Earth's surface is called, "Weight".
The sun is not the only gravitational force but it is the strongest, the earth has a gravitational force, the moon has a gravitational force etc. Any two objects have a gravitational force between them that is proportional to their masses and inversely proportional to the square of the distance between them.

Yes, no, and we are not really sure. The basic formula to calculate the gravitational force between any two objects in the universe is:F=G{[(m1)(m2)]/(r2)}whereF= Force of gravity between two objectsG= The universal gravitational constant (6.64 * 10-11 N(m/kg2)m1=The Mass of object 1m1=The Mass of object 1In order to achieve a negative gravity or a repulsive force, you would need to have at least one negative mass object, which in general is not seen to be plausible. However, there are other possibilities. See this page for a more detailed answer :http://en.wikipedia.org/wiki/Anti-gravity
