Gravity is a proven fact, and not just on earth. We found Pluto because we saw the effects of its gravity, we were able to land on the moon thanks to gravity. Your denying that gravity even exists shows your total disregard for both science and honest discussion.-me-

Really? Can you explain the difference between pure Newtonian physics and General Relativity? Why do you think its called Gravitational Theory?

For a supposed astronomer you do not even know your terms. It is called the LAW OF UNIVERSAL GRAVITATION it is far more than a theory. As I told physicist, by denying something which you know to be true you are being dishonest. If you are a radio astronomer you know that gravity has been observed. If you do not know it, then you are not a radio astronomer, so either way you are being dishonest.

You and your friends are trying to create confusion in order to try to dismiss my posts as nonsense. Specifically that gravity has been observed and evolution never has been observed. I ask all those who do not believe that gravity has been observed or do not believe that it is observable to go on top of a 20 story building and jump. This will have two benefits: one it will prove to you that there are indeed universal scientific laws, and two, it will rid the world of a few people lacking in common sense (and perhaps win you a posthmous Darwin Award!). Gravity is observed everyday by everyone. Evolution has NEVER been observed.

BTW - it is interesting that evolutionists when shown that some scientific statement is true, try to challenge the truth of a scientific theory instead of prove their own evolutionary theory. It shows clearly to me that evolutionists are quite aware that evolution is not a fact, but just rhetorical nonsense.

Ah, here we go again. This is reminiscent of “is a circle is an ellipse” (which BTW you never did acknowledge).

A little history here:

Newton’s Law of Universal Gravitation

“Every object in the universe attracts every other object with a force directed along the line of centers for the two objects that is proportional to the product of their masses and inversely proportional to the square of the separation between the two objects.”

F=Gm1m2/r2

Where:

F equals the gravitational force between two objects
M1 equals the mass of the first object
M2 equals the mass of the second object
R equals the distance between the objects
G equals the universal constant of gravitation = (6.6726 )* 10-11 N*m2/kg2 (which is still being refined and tested today)

(BTW this is a simple form of the equation and is only applied to point sources. Usually it is expressed as a vector equation)

Even though it works well for most practical purposes, this formulation has problems.

A few of the problems are:

It shows the change is gravitational force is transmitted instantaneously (Violates C), assumes an absolute space and time (this contradicts Special Relativity), etc.

Enter Einstein’s General Theory of Relativity

In 1915 Einstein developed a new theory of gravity called General Relativity.

A number of experiments showed this theory explained some of the problems with the classical Newtonian model. However, this theory like all others is still being explored and tested.

So, YES, the term “Gravitational Theory” is quite valid.
