NASA said:All types of light, including X-rays, are also affected by gravity. An analogy is that of a person running up an escalator that is going down. As they do this, the person loses more energy than if the escalator was stationary or going up. The force of gravity has a similar effect on light, where a loss in energy gives a lower frequency. Because light in a vacuum always travels at the same speed, the loss of energy and lower frequency means that the light, including the signatures of iron and silicon, shift to longer wavelengths.
NASA said:This is the first strong evidence for absorption signatures being shifted to longer wavelengths by gravity in a pair of stars that has either a neutron star or black hole. Strong evidence for gravitational redshifts in absorption has previously been observed from the surface of white dwarfs, with wavelength shifts typically only about 15% of that for 4U 1916-053.
Scientists say it is likely that a gaseous atmosphere blanketing the disk near the neutron star (shown in blue) absorbed the X-rays, producing these results.

An effect predicted by Albert Einstein has been identified in a double star system about 29,000 light years from Earth.

First, the analogy with a person running up an escalator that is going down and the energy thereof is explained by newtonian physics and has nothing to do with general relativity. The analogy doesnt prove anything related to general relativity, therefore its illogical and stupid.
It is also stupid because a person is a physical object made of atoms that have mass, while light, being a wave, doesn't have mass. Its like comparing apples with light waves. If a light wave falls on your head, then you know Einstein was right and gravity is a force. Just like Newton said when the apple hit him with brute force.
Except gravity is not a force in general relativity, but in classical newtonian physics. NASA in this article which 'proves' Einstein right claims that it is a force, which contradicts Einstein's theory which claims it is a curvature of spacetime and NOT a force. Therefore, NASA is stupid.
Then it goes to show that this force of gravity has a similar effect on light, cause light looses energy just like a person does when it runs up an escalator going down.
Except light has no mass to move, because it is massless, so it looses no energy when it moves up while going down a gravitational escalator, which cannot move light at all cause light aint like a person which gravity can pull.
And because light always runs at speed c in a vacuum, effortlessly, while the person needs to accelerate from a standstill and push his own mass up in order to run on the escalator, which makes him loose energy. Light doesnt need to push its mass up, against gravity, because it has none, so it looses zero energy.
But the biggest stupidity is that these NASA scientists confuse the redshift from refraction with one from gravitation, despite the fact that they aknowledge that the redshifted Xrays were absorbed (and reemmited) by the neutron's star gaseous atmosphere ! They make the same mistake that Pound and Rebka did, using speed c of light in a vacuum and applying it to the equation f=c/lambda, which yields a decrease in frequency when the wavelength lambda is increased.
They assume that the xrays always travel at c the speed of light in the vacuum, when they obviously do not always travel in a vacuum as they first travel through the gaseous atmosphere of the stars ! So their innitial speed is not c but v=c/n, and it only increases to c when they go into space, which is a vacuum, which makes them refract into space, and change their wavelength from REFRACTION! Because when v increases to c then the wavelength increases to preserve the frequency f=v/lambda. So there is no loss in energy whatsoever from gravity, because the frequency does not change, only the speed of light changes when it refracts into space !
But these complete idiots completely ignore refraction just like Pound and Rebka and Shapiro did when they proved Einstein using helium or the sun's heliosphere, and use c as the speed of light everywhere in their calculations, which then result in a decrease of frequency and a loss of energy.
Whereas if they use v=c/n, as they would were they not complete idiots, there is no loss in frequency and energy whatsoever, and no gravitational redshift.
EDIT: If there is a loss of energy, it is because the Xrays loose energy in the gaseous atmosphere as they are partially absorped by it, and not because of gravity or relativity. (obviously if they were completely absorped we would not be able to detect them).
So it might be that the perceived redshift is a combination of the redshift from refraction, and that from absorption. Either way, it has absolutely NOTHING to do with gravity or relativity.
