Newton's Law of Gravitation 1000 before Newton

Newton's law does not say the bodies fall towards the Earth, but that there's an attraction force between any two bodies proportional to their masses and inverse proportional to the square of the distance between them.

The problem is that most idiots think thats what he discovered.

Consdering that Brahmagupta lived in around 500 A.D about 700 years ago before Algebra was first fully formualted by "Bhaskara" as Bijaganita in 1200 A.D, i think that you rally cannot hold it against Brahmagupta that he did not formulated the algebraic form of this law.

You can't take credit away from Newton then. The mathematical form is very important.

Nor should you give credit for algebra to Bhaskara. al-jabr was written in 820, and examples of algebra have been found that are from 1800 BC.

He clearly says that "bodies fall towards the earth because earth attracts them towards its center" not just that "bodies fall towards the earth".    "All heavy things are attracted towards the center of the earth"   "for it is the nature of the earth to attract and to keep things"   "Bodies fall towards the earth as it is in the nature of the earth to attract bodies"

That's not the law of gravitation even in conceptual form. Had Brahmagupta added that it is "the nature of bodies to attract the earth as well" he would have gotten close though. As said, even the cavemen probably noticed things fall towards the earth; only Newton was the first to realize the earth "falls" towards the falling things also. So, Newton still gets all the credit, for the principles as well as the mathematical description.

If came next civilization cycle,could be reinvented human being.Same is with our knowledge.Newton had patented this law first than.

If it is within the bounds of believing that "all bodies are attracted to the Earth, or the Sun" is correct, then just why is our very Moon, moving away from us?

This is a sincere and very valid scientific truth!

Just think of the tides that used to swiftly move across the planet Earth when it was twice as close, etc.?

While I am not an expert in math, etc., I would suppose that these gravity tides were almost exponential in the degree of movement they would cause upon our planet. Thus at one time, if we considered that most of the Earth was water, then 1,000 foot tides came in and out quite quickly. And even if we were to take water out of the equation, in the earliest times, even the crust of the Earth would be pulled outwards from our planet to a great degree.

There exist sites that really explain all of this, I would recommend that all of you fire up your seach engines for this ride?

Perhaps this is where the song "rolling, rolling" came from? Laugh
