Hmmm.. First my apologies for not being more clear on this. Lets see....
Newton came up with a mathematical formula that described a falling object or a planet in orbit around the Sun, etc. We call this force Gravity.
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 (Law of Gravity). However, this theory like all others is still being explored and tested.
You're always clear, Radio Astronomer, it's just that your expertise on matters such as gravity is far above that of most of us!
Yet simply stated - what goes up must come down. Please don't make this more complicated than necessary. We all know gravity exists. We may not be able to explain it, but we certainly can verify it. Not so with TOE (of course no one is arguing adaptation of species). But as I've often said, no one's mind will be changed on FR. We have believers on both sides of the argument who, come hell or high water, aren't about to change their beliefs.
Hope you and your family had a wonder Christmas and a Happy New Year.
