Zero Gravity and Anti gravity Space Adjustment r = ((m1*m2+m1*m2)÷2F )

Zero Gravity  and Anti gravity Space Adjustment where g=r in
f = g(m1*m2)/r^2
= r((m1*m2)÷2)+r((m1*m2)÷2)/r^2
=(( m1*m2)÷2r)+((m1*m2)÷2r)

= (m1*m2+m1*m2)÷2r or 2g
= (m1*m2+m1*m2)÷ 1.3348E−10


Gravity do really exist based on above observation ?
What happening is space adjustment in internal structure of an object with a mass and r = ((m1*m2+m1*m2)÷2F )
may be the required space adjustment in vector field within each object in its nucleus proportionately to change the gravitational constant itself.
if we consider m1 and m2 = G then the mathematical possibility shows G^2+G^2 ÷2F to be Zero gravity and larger than this value may be anti-gravitational.

If your mind is not clear on the logic behind the mathematical possibility, just graph the equations in a 3D Grapher as follows :

x = sine(x)

x 1= cos(x)

x2 (x,z)=( G^2 + G^2)÷2r

y (x)=  (G^2 + G^2)÷2x2

z (x,y)=   (G^2 + G^2)÷2x2

Science Fiction and Fact thoughts on Constant Motion : If a zero gravity object or anti - gravity or negative gravity object in circular motion and exposed to gravity such object will have a curved motion <= 180° or <= π radian ( eg: gravity exposed at sine(45°) may give a value >  sine(45°) and <=sine (225°) , the minimum value  will always be more than sine(135°). It may be similar to the graph function f(x)=sine(x) or cos(x).

And if gravity exposed Sine(0° to 50°) give a curved motion <=180° then Gravity exposed Sine (310° to 360°) must also give an exactly opposite curved motion, both these motion will have a displacement of the object in a point in straight line and such displacement can varying based on force and velocity. The curved motion itself can be changed to spiral or helical motion based on the force applied on the varying radius, force,  angle or velocity.

If an object named A contain two parts and one part(Object1) subject to Zero gravity or Anti-gravity or Negative gravity  as Static Object1 and Another in part (Object2) is also same type of Anti-gravity or Zero Gravity or Negative Gravity or Gravitational in Circular Motion  and these two objects are exposed to same gravity or varying gravity to each other these may produce their  own gravitational fields and Object A (containing Object1 and Object2) will move in the field of higher Gravity Object and the length of curved motion will vary based on the radian of the gravity exposed to each other. If gravity is applied on varying 'radius’, and angles ,the object may have helical motion or spiral motion in varying radius and these object will be always have variable speed and not limited by any constant including speed of light.

Real world fantasy observation :  if moon as sphere had a only a radian part on its sphere, the moon will not be in complete circular motion and may start moving away from earth and solar system , still it find a gravitational equality. Which means partly gravitational or anti-gravitational is already capable of self motion in the field of an object of higher Gravitational Object , once the object set to unrest by a Force. However the motion will not be same in momentum or velocity for moon, it can some time curved, helical, spiral in various radius because when it enter and changed into the gravitational field of Sun or another plan or Star. As long as there is another gravitational field moon will be in constant motion. This journey of moon may start to reverse to a reverse velocity (back to point of origin) when moon will encounter a gravitational opposite having exactly opposite or more than the Gravitational force of moon moving same like moon and moon enter in that gravitational field. If moon never find such a filed, moon will be in constant motion and will collide ,if and only if it ever find encounter into a gravitational opposite or gravity neutral field. This may be the reason that some planets and stars are always on constant motion.If a sphere has a partial Anti-gravity on any of it's pole or core and if the core produce magnetic waves such magnetic wave will be move in one direction.
