Of course time seems to "run" slowly as we increase the distance from the planet's surface! It's a fact that a satellite orbiting the Earth at 4.1 radii from the center of the planet will see a time contraction of 11 seconds in each rotation... The problem was a theoretical one faced by those working in the program called "Global Positioning Satellite."
The whole logic in it is simpler than we could think. If you draw a circle with [let's say...] a radius of 1 inch and around it you do the same but with a radius of 4 inches then what would happen if you decided to make the point o two pens moving at the same exact speed following the figures?

Piece of cake! The pen moving on the outside circle will fall BEHIND with respect to the one with a smaller radius... right? FINE!
It wasn't necessary at all the complicate things the way Einstein did. Assuming light could also propagate following an ARC [hypothetically speaking of course] instead of in a straight path as it does, it would be pretty easy to see why the light ray forced to spin in the larger orbit will be left well behind.
E-m energy DOES spin around in atomic orbitals and that is the reason time lags from one harmonic to the next!
Back into special relativity, light in the vacuum can not propagates in curves [unless being affected by other reasons we all know] but assuming it could, for the sake of our thought experiment, it is "VISIBLE FOR OUR IMAGINATION" why both systems were time-incompatibles.
The only way to make a PERFECT system of correspondence between all possible inertial frames would be to assume the very center of the circunference [circle] as the time-reference point.
The satellite [and this is a fact] did not showed evidences of a great time discrepancy while moving in a shorter orbit [2 radii from the center of the Earth]. It was only when it reached the altitude of 4 radii or more that a time lag was causing real problems while directing a bombing operation against a target [for example]... let me remind you that GPS was a secret military program in its beginings, well it still is.
The only point in the Earth capable of making A UNIQUE or COVARIANT reference frame would be the CENTER OF THE EARTH.

Newton and Galileo knew already about the relativity of movement in their old days...It wasn't something new. However they assumed that time was absolute and that it could be a common reference for any other inertial frame every where in the universe. A sort of "universal clock." Now! I wonder myself if that universal clock could actually exist somewhere... I tell you what, It may indded exist but so far from here that we will never reah it...
I'll try to explain: In my thought experiment above I assumed an impossible theoretical point of view [nothing really unusual in physics as I'll explain later] where light could move in any chosen path other than the straight line. Considering two circular perimeter or path with different radius between them I could [easily] observe that one light beam [the one moving with agreater radius] stayed behind the other. Reality shows us that a satellite shows a time differencial NOT BECAUSE IS TRAVELING CLOSER TO THE SPEED OF LIGHT but because moves in a greater angle from the Earth's core... This are facts gentlemen!
I then assume this phenomenon to conclude that it is the actual radius and therefore the angle of the momentum followed by an object what defines its own inertial frame and its own space-time attributes and nothing else.

Suppose that you have two objects moving at the same speed in complete geografic position in the planet [one over the U.S.A. and the other on China] exact 180 degrees angle from the center.

As both move in opposite direction we can say that there is a time differential in the inertial system of coordinates. We would be looking at a MIRROR-IMAGE of the same inertial frame! In the center of the Earth every space-time reference is the image of the one moving exactly 180 degrees from the other...
Think about it!

This is part of my response to Tony staton's post:
But concerning the generation of space and time I did wrote a lot in this forum and in my book. I said that I refused to accept gravity as the result of warped or curved fabric of space-time and the reason for that is because I see gravity as the result of a quantum mechanical process occuring inside the SUN.
In my book and my posts I have referred to the conexion between spin and time [read my article "The young experiment" right here in this forum if you want to see my side of the story] Anyway!
I do believe as you stated that space and time are being generated [created] but in my picture I assume that reality [space and time are a consistent reality] being borne in stars and no where else.
Earth rotates around the sun [in my views] not because space-time was warped by the solar mass, because there is a quantum mechanical process of spin amplification around the sun in a "MACRO-SCALE."
The true reason for attraction between electrical bodies do have a time interpretation since I have said before [here in this forum] that harmonics spinning around the atomic core (I called them standing nuclear waves) DO rotate IN THE CONTEXT OF SPACE-TIME different one from the other.
I depicted a horse race where in each harmonic [track] a horse [energy] could move only at discrete rate of time... It's all in the article "The young experiment." I also published it in a web page called sidewlakastronomer.com

I do believe that what we called space and time or what we refer to it in our science is all "produced" by the process of interaction of energy at a huge scale inside stars. Just like inside an atom we find orbitals [harmonics] the same way in the macro-world there are planetarium orbits around the source of that reality: stars. Those individual star-systems are also spinning around a center where all galaxies are connected and right in the very core of that spinning system would be found our "universal clock."

I know! Too far to be prove! I know the response that some members of this forum will write... so I would say that I had anticipated their inertial thoguht of frames this time right? [just kidding!].
