Title: Gravity is limited to a range: A mathematical explanation
Post by: Yahya A.Sharif on 31/03/2019 12:02:32
Gravity has a limited range "doesn't exist at infinite distances" and spread out with the speed of light c:

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 an object will jump from a number to a nearby number  gravity jumps to  zero while space continues to infinity

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

An object can't exist at infinite distance but there still 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 the smallest number i.e the zero" but where if space is infinite where is this point of non-existence of gravity ?

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.

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.
You mean 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.

Then gravity approaches zero without reaching it is not logical .gravity jumps from value to value  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 if gravity jumps from number to number it would jump to zero while space continues to infinity

The existence of mass causes non-existence in space-time causes space-time to displace causes it to bend, the existence of mass occurred a particular moment at the speed of light c.

The Newtonian equation of gravity is valid, but in fact gravity spread with the speed of light c and decreases approaching zero and will never reach zero , however it has a specific range beyond its range it exactly equals zero. For instance earth mass has gravity still decreases today with the speed of light it has very small minimum value"changeable" and very large range"also changeable"
