The Fundamental Difference between General Relativity and Newtonian Celestial Mechanics and Optics.

In Newtonian Celestial Mechanics the star moves, sharing a barycentre with the planet. It is this motion of the primary that is currently being used to detect otherwise invisible planets

Here we add the velocity of the star to the velocity of light, the faster image passes the slower, but only if the distance is great enough.

Next we plot a distance/time graph, showing a DT in the time of arrival of the image at the top. This variation in DT is very real, as indicated in   http://nobelprize.org/nobel_prizes/physics/laureates/1993/press.html wherein is written: "The observed period actually varies by several tens of microseconds, i.e. by an amount that is much greater than the variation in the mean value. This is a Doppler effect, and led to the conclusion that the observed pulsar moves in a periodic orbit, meaning that it must have a companion. As the pulsar approaches the earth, the pulses reach the earth more frequently; as it recedes they arrive less frequently. From the variation in pulse period, conclusions can be drawn about the pulsar's speed in its orbit and other important features of the system."

However, it is basic tenet of Special Relativity that light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body. This means that the slope of the ray in the diagram above cannot change, and must be as shown in red in the diagram below.

 

From that it is at once clear that Dt, the difference in time between pulses seen at the telescope, must vary at the source. This variation in time must be accounted for with General Relativity and is caused by "gravitational red shift". You can see this silliness in wackypedia. http://upload.wikimedia.org/wikipedia/commons/5/5c/Gravitational_red-shifting.png

Thus the difference between Newtonian Mechanics and General Relativity is nothing more than a faithful devotion to the infallibility of the St. Einstein the Divine and a slavish belief in one speed of light only, as if aether existed.

"Everything should be as simple as possible, but not simpler" -- Albert Einstein.

I have made it as simple as possible, but not simpler. Einstein was an idiot and so were the Nobel Prize committee to praised Hulse and Taylor.

"Pluralitas non est ponenda sine neccesitate" - William of Ockham

Sir Isaac Newton's RULES OF REASONING IN PHILOSOPHY - Principia Mathematica.

RULE I.

We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances.

To this purpose the philosophers say that Nature does nothing in vain, and more is in vain when less will serve; for Nature is pleased with simplicity, and affects not the pomp of superfluous causes.

RULE II.

Therefore to the same natural effects we must, as far as possible, assign the same causes.

As to respiration in a man and in a beast; the descent of stones in Europe and in America; the light of our culinary fire and of the sun; the reflection of light in the earth, and in the planets.

RULE III.

The qualities of bodies, which admit neither intension nor remission of degrees, and which are found to belong to all bodies within the reach of our experiments, are to be esteemed the universal qualities of all bodies whatsoever.

Idiot Einstein's silly guesses:

"light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body"

 "We have not defined a common "time" for A and B, for the latter cannot be defined at all unless we establish by definition that the "time" required by light to travel from A to B equals the "time" it requires to travel from B to A. Let a ray of light start at the "A time" tA from A towards B, let it at the "B time" tB be reflected at B in the direction of A, and arrive again at A at the "A time" t'A."

Did Hulse and Taylor emit a ray of light to PSR 1913+16 and wait for it to be reflected?
