I know that the force of gravity is based on the mass of an object and on a scale from 0 to infinity it would be linear or a steady incline. For example Earth=1 and a black hole=1000 and all points in between would be equally spaced. My thoughts are that gravity is not consistently linear through out the universe. The circumstance for the variation in gravity is up in the air (meaning I don’t know) however I am curious to know what you think. Also please don’t answer my question with a question, which I am sure there are many.

yes i think your thinking is correct. because even i believe that there must be variation of gravity due to the presence of dark matter and many components of universe like curvature of universe. since the universe is curved there is a change in distance therefore as gravity depends on distance inversely there must be variation of gravity though if objects have same mass and distance between them. i would suggest you to check HALLIDAY RESNICK EXTENDED for further information..

Because its in 3 Dimentions, where as your linear graph is in 2 dimentions. If you were to measure a straight line from here to the moon, you could create a linear graph. Unfortunatly in reality, that linear graph will cross thru the graph from here to the sun, and from here to alpha-centuri, and every other line from here to every source of gravity that exists. Gravity is always attractive - unlike for example a magnet with a Positive and Negative - Gravity is always positive and thus always additive.
Gravity is not only a question of how much of something, but also of how far away it is. Additionally there are many trillions of sources of gravity throughout the known universe (any object with mass). This is important; because of the uneven distribution of matter, as you travel through space you will be heading closer to some sources, and further from others. This means the effects of gravity are inconsistant thru-out space. Remember that gravity is relative, and thus felt different for anyone at anygiven time. Imagine a skydiver and the pilot of his plane. Before the jump both feel the same effects of gravity, after the jump, vastly different. Because most of the sources are billions of lightyears away you cant actually feel them, the pull its so subtle. Only while flying closly past some massive object would gravitys effects be physically apparent. Gravity is considered to be a very very weak force.

Linear with respect to what???
Gravity depends upon the mass of the body, and the distance of the mass from the object experiencing the gravity.
The variation of gravity with the mass of the body is linear, wheras the variation with the distance is not linear..
A(acceleration due to gravity or G Force)= GM/(r^2) where G is a universal constant, and r is the distance from the centre of the body.
Of course this is non-relativistic, Newtonian mechanics...

Well, the force of gravity is directly proportional to the masses of the two objects (m1 and m2), and inversely proportional to the square of the distance (r) separating the two centers of mass, but there is a **fixed** gravitational constant.
The equation for gravity -- the force of attraction between two masses -- that is as follows:
F = G(m1m2/r²)
where the gravitational constant, G = 6.672E-11 m³/kg-sec²
So, while the force of the attraction varies with distance, the gravitational constant is just that -- constant.

Gravity is constant for a given planet. The earth's gravity is constant, the moon's gravity is constant.
The only situation where gravity may not be linear is in the case of a black hole. There may be a threshold where gravity begins to multiply exponentially. This is only a theory of course.

Gravity is a dimensional direction that is precieved as a force as it interacts with the thirty or forty other dimensions that make up our trans dimensional multiverse. It only varies in the presence of an anti gravity generator which creates opposing dimensional fields to counter act the force of gravity. You can buy them at the K-Mart on Sigma-Epsilon 5.

Gravity varies in relation to the density of space.

gravitational force is the inverse square of the distance not a constant

No, gravity is not constant. Gravity can be defied many ways that seem humanly impossible or charismatic. Example: Jesuus was here before creation and yet He died, rose, ascended, and will descend in His second coming.

1. Depends which planet you are on
2. Not in a black hole
