Time-delay of light caused by refraction, not Gravity.

Clocks in a gravitational force.
When comparing a clock under the influence of gravitational forces with one very far from such influences it is found that the first clock is slow compared to the second. To see this consider the same clock we used in the Special Theory of Relativity. For this experiment, however, imagine that the clock is being accelerated upward, being pulled by a crane. The clock gives off a short light pulse which moves towards the mirror at the top of the box, at the same time the mirror recedes from the pulse with even increasing speed (since the box accelerates). Still the pulse eventually gets to the mirror where it is reflected, now it travels downward where the floor of the box is moving up also with ever increasing velocity.
On the trip up the distance covered by light is larger than the height of the box at rest, on the trip down the distance is smaller. A calculation shows that the whole distance covered in the trip by the pulse is larger than twice the height of the box, which is the distance covered by a light pulse when the clock is at rest.
Since light always travels at the same speed, it follows that the time it takes for the pulse to go the round trip is longer when accelerating than when at rest: clocks slow down whenever gravitational forces are present.
This has an amazing consequence: imagine a laser on the surface of a very massive and compact planet (so that the gravitational field is very strong). An experimenter on the planet times the interval between two crests of the laser light waves and gets, say, a millionth of a second. His clock , however, is slow with respect to the clock of an observer far away in deep space, this observer will find that the time between two crests is larger. This implies that the frequency of the laser is larger on the planet than in deep space: light leaving a region where gravity is strong reddens. This is called the gravitational red-shift (see Fig. 7.9).

Figure 7.9: The gravitational redshidft. Since clocks slow down in a strong gravitational field then light, whose oscillations can be used as clocks, will be shifter towards the red as it leaves a region where gravity is strong.
As for time dilation, the slowing down of clocks in the presence of gravitational forces affects all clocks, including biological ones. A twin trveling to a region where gravity is very strong will come back a younger than the twin left in a rocket in empty space. This is an effect on top of the one produced by time dilation due to the motion of the clocks. The gravitational forces required for a sizable effect, however, are enormous. So the twin will return younger...provided she survives.

The thought experiment above is incorrect and misleading because it ignores the refraction of light. The speed of light will always be slowed when light passes through a layer of earth atmosphere.

"Since light always travels at the same speed,..."
This statement is misleading. Speed of light is not constant but slowing down causes by refraction. The time-delay of light cause by refraction, not gravity.
An example in the case of sunlight, please see picture below:
A'-B is a straight line light of apparent position of the Sun, and A - B is a curved path of true position of the Sun.. A curved path A - B is a litle bit longer than A' - B.
GPS Doen't Need, Doen't Use, and Does't Prove Einstein's Theory of Special and General Relativity.
Einstein's general theory of relativity was totally wrong.
1.Einstein's thought experiments are incomprehensive, illogical, and misleading.
2.Einstein's equivalence principle is false.
3.General relativity inconsistent with Special relativity about the existing of an aether.
4.Special relativity and General relativity ignored the refraction of light, so:
5.The deflection of light by the Sun is misleading. The deflection of light is caused by refraction, i.e.astronomical refraction and terrestrial refraction.
6.Gravitational redshift is misleading. Redshift and blueshift are caused by refraction, not gravity. When the celestial bodies become incasdescent as the temperature increases, they emit a red glow that we see as redshift. If the temperature continues to rise, the red glow turns to orange, then the yellow, and then the blue that we see as a blueshift, the blue glow then turns to white. The amount of radiant energy given off by such celestial bodies varied with wavelength and temperature. Such phenomena isn't Doppler effects. Thus, redshift isn't Doppler effect.
7.Gravitational lensing is false. Lensing is caused by refraction, not gravity.
8.There’s the Shapiro time delay. There’s gravitational time dilation. Gravitational time dilation is not correct. Because the revelation of universal law: 'the velocity of light is constant' (Special Reltivity) is misleading. Speed of light slowing down causes by refraction when the starlight passing through the Earth’s atmosphere.The time-delay of light caused by refraction, not gravity.
9.GPS doesn’t need, doesn’t use, and doesn't prove Einstein’s special and general theory of relativity.
a.By ignoring General Relativity, GPS is wrong by about a third of a nanometer here. Since GPS is known to be accurate only to about 5cm (with full augmentation), and since even “post-mission measurements” claim only an accuracy of 1mm or so, the GR margin of error is well below those limits. This is true even when light has to travel much further than the 30 million meters we gave it above. It could go a million times further than that and still not impact the current accuracy. That is why GR can be ignored in GPS.

b.The GPS satellites use classical (Newtonian) relativistic principles to work. These are the same relativistic principles that make sense in the everyday world, that most people equate with 'common sense'. GPS calculates positions based on geometric principles. The atomic clocks on the satellites have their rates preset in order to match experimentally observed effects. No General Relativity is used or needed.( Analysis by Wandera)
c. Atomic clocks at higher altitude tick faster than clocks on Earth's surface. It is not caused by gravity, but by air density of atmosphere. Closer to the earth surface, the air is denser compared to the density of the air layer above it. The density is getting looser or weaker when it is getting higher.(oejicoba.co.id)
10.Black holes do not exist, the expanding universe and the big bang theory is incorrect.
11.About gravitational waves Einstein was wrong.There are no such things as curved/warped space. Space-time just a mathematical model.There are no gravitational waves or ripples in space-time. Where does energy for gravitational waves come from? Gravitational waves don’t carry any energy, so they’re just a formal mathematical construct with no real physical meaning (Nathan Rosen, 1955). Gravity is a real force, there are exist gravity waves, not gravitational waves.In the Earth’s atmosphere, gravity waves are a mechanism for the transfer of momentum from the troposphere to the stratosphere.
12.Dark matter and dark energy do not make sense. This time 2016 is the end of the 9 biggest unsolved mysteries in physics, 8 of 9 unsolved mysteries are caused by the failure of general theory of relativity.

Discoveries 2016: Should we reshaped the Modern Physics?
Description
Albert Einstein was one of the greatest physicist.Therefore, it is hard to understand he made a mistake in his thought experiments-equivalence principle-moreover in his proving method to prove his hypothesis.In fact, we found something new.
Did you know, Einstein's thought experiments are incomprehensive,illogical, and misleading?
The equivalence principle is false, and Einstein's proving method for his hypothesis 'deflection of light by the Sun' isn't scientific and deeply wrong? Unfortunately, a revelation of universal law 'the velocity of light is constant' and gravitational redshifts also incorrect......Einstein's gravity was wrong, and Newton's gravity was correct. But we know that our understanding of gravity is not complete. What is gravity? Gravity is not just something of a force that any two bodies in universe attract each other, but moreover, gravity is the force due to the effects of well balanced universe ..... .
