Gravity has a limited range "doesn't exist at infinite distances" and spread out with the speed of light c:

Mathematical explanation :
The existing fact says gravity is available every where in space to infinity and approaches zero without reaching it while space approaches infinity

In the gravitational equation the force is inversely proportional to the distance, as the distance gets bigger and bigger the force approaches zero. We can notice that force approaches zero “a real number” but space approaches infinity” unreal number”

In the number line when moving to the right from for instance the number 3 to the number 4 there is a possibility of infinite numbers greater than 3 and less than 4 instead of reaching 4 a moving object could move infinitely to reach 4 and will never reach it. it will move for instance from 3.4 to 3.49 to 3.499 to infinity regardless its speed it won’t reach the 4 however in fact an object will cover infinite fractions to reach  4 , gravity covers infinite fractions and reach 0  while space continues to infinity.

Then gravity approaches zero without reaching it is not logical .gravity covers infinite fractions and reach 0, if it is not, a value of for instance 3g won't reach 2g since it would move to 2.9999999→infinity without decreasing to 2g , gravity will cover  infinite fractions from 3g to 2g and from 2g  to  zero while space continues to infinity.

An object can't exist at infinite distance but there still exists zero effect of gravity for that object although there is not a place for it to obtain zero effect. So there is non-existence of gravity at a point in space" logically gravity decreases and that has an end which is the smallest number for gravity i.e the zero" but if space is infinite where is this point of non-existence of gravity ?

Think of a number line of 1 meter length it is divided into units it starts from 4 at the beginning and zero at the end. Let’s imagine gravity value close to mass being 4 and at some distance being zero or the end of gravity range. Now think of another number line a bigger line of 4 meters length also has an end point of zero unit. The existing fact means we have a number line of length infinity and two ends one is a specific number and the other is the zero this is impossible a number line equals infinite length doesn't have end points gravity has end points one of them equals zero.

The Newtonian equation of gravity is valid , all other equations of potential energy ,etc are valid the escape velocity is true. In my concept gravity decreases with the increment in distance my concept has the same values as we have in current view” g=9.8 m/s/s on earth surface both in current view and in my concept” the difference is that the equations are applied to a specific range beyond that range the equations are not applicable beyond that range the gravity value drops suddenly to zero value.

If something is an infinite distance away it cannot affect you, plain common sense.

PS:"the smallest number" I don want to involve in negative numbers so I mean the zero.

What is the big deal, as the distance between particles tends towards infinity, gravity tends towards zero. Infinity is a conceptual number that can never be attained, so whilst g tends to zero between particles it is never reachable. Although your 64bit processor in your computer might think it has reached zero, which to all intents and purposes it has.
