If Newton's Universal Law Of Gravitation was obtained through inverse proportionality techniques, than what is it inversely proportional to?

As I stated in another thread on the matter, the Universal Gravitational Constant wasn't scientifically measured until 100+ years after Newton did his work, by Henry Cavendish.

Now I threw around some possibilities, like algebraic rearrangement to find the constant, but that in itself would have required information that can only be obtained VIA THE CONSTANT.

The best answer anyone could come up with, is that I was an idiot, and that "He found it through inverse proportionality, duh"

No evidence for this can be found, nor do any college texts state how he obtained it, nor how to obtain it yourself.

Now since we're talking about a number that is SO SMALL, that it's literally only ten to the negative eleventh in size, than that means that taking the inverse of of the squares of normal numbers, will not result in an aswer that is anywhere near that.

The numbers that Newton had to play with were BIG NUMBERS, massive really, and none of them combined in any way, would result in that constant.

And again, where are the science guys? They spent hours Bashing Einstein's theory of relativity, although in order to really understand the mathematical relevance, you have to be nearing PHD level, but they won't chime in on this at all.

I know you guys are out there and have seen this.

f = Gr^2

By god you are stupid.

What's the opposite(inverse) of f(force), which is something that repels?

Might it be attractive(gravity)?

Much smarter people than you already figured this shit out. What's your problem?

Is this guy below you in real life?

First of all, you posted the equation incorrectly. Radius squared is in the denominator. second of all the large 'G' is what is in question here, you dumb ass.

These shills will go to the end of the earth to try to put a lid on all of this.

For the layman, the bastardized equation that the shill posted pertains to measuring the gravitational force between two objects, that REQUIRES the Universal Constant of Gravitation, which is the particular number in question.

Instead of bastardizing equations, and poorly shilling, what you need to come up with an answer for is G = ?, which you'll never do.

The specific number in question here is 6.67408 × 10-11.

How did Newton obtain it without scientifically measuring it?

I'll add too, that if someone does manage to post an equation that does sufficiently equate to G, the information MUST consist of information that does not require the Universal Constant of Gravitation to obtain in the first place.

If you do that, your answer is null and void, unless you can properly explain how he would have gone about obtaining that information without using G.

When I say large G, I do mean large
