Light flowing through space expands with it for billions of light years. There is no prefered scale for inbetween galaxies. Orbits and light expand. This is universal evolution. Mitch Raemsch
From: Pentcho Valev on 20 Jun 2010 00:51 Why is light redshifted in a gravitational field? The journal Nature explains: http://www.nature.com/news/2010/100617/full/news.2010.303.html Nature: "Gravity is mercilessly impartial - on Earth, it accelerates light and heavy objects alike with a tug of 9.8 metres per second squared." Yes, the frequency shifts because THE SPEED OF LIGHT SHIFTS, in accordance with the equation c'=c(1+V/c^2) given by Newton's emission theory of light (V is the gravitational potential difference between the point of emission and the point of reception of light). Believers would not understand the importance of Nature's confession but at least they could stop singing "Divine Einstein" and "Yes we all believe in relativity, relativity, relativity", just in case: http://www.haverford.edu/physics/songs/divine.htm No-one's as dee-vine as Albert Einstein Not Maxwell, Curie, or Bohr! He explained the photo-electric effect, And launched quantum physics with his intellect! His fame went glo-bell, he won the Nobel -- He should have been given four! No-one's as dee-vine as Albert Einstein, Professor with brains galore! No-one could outshine Professor Einstein -- Egad, could that guy derive! He gave us special relativity, That's always made him a hero to me! Brownian motion, my true devotion, He mastered back in aught-five! No-one's as dee-vine as Albert Einstein, Professor in overdrive! http://www.youtube.com/watch?v=5PkLLXhONvQ We all believe in relativity, relativity, relativity. Yes we all believe in relativity, 8.033, relativity. Einstein's postulates imply That planes are shorter when they fly. Their clocks are slowed by time dilation And look warped from aberration. We all believe in relativity, relativity, relativity. Yes we all believe in relativity, 8.033, relativity. Pentcho Valev pvalev(a)yahoo.com

If this were not so, there would be no bending of light by the gravitational field of stars....Indeed, this is exactly how Einstein did the calculation in: 'On the Influence of Gravitation on the Propagation of Light,' Annalen der Physik, 35, 1911. which predated the full formal development of general relativity by about four years. This paper is widely available in English. You can find a copy beginning on page 99 of the Dover book 'The Principle of Relativity.' You will find in section 3 of that paper, Einstein's derivation of the (variable) speed of light in a gravitational potential, eqn (3). The result is, c' = c0 ( 1 + V / c^2 ) where V is the gravitational potential relative to the point where the speed of light c0 is measured." THEOREM 1: The speed of light obeys the equation c'=c(1+V/c^2) if and only if, in the absence of a gravitational field, it obeys the equation c'=c+v where v is the speed of the emitter relative to the observer. Both equations belong to Newton's emission theory of light and contradict Einstein's 1905 light postulate: http://www.fourmilab.ch/etexts/einstein/specrel/www/ "...light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body." THEOREM 2 (The Redshift Law): If the assumption that the wavelength of light varies with the speed of the observer is absurd, then the following unversal equation holds: f'/f = c'/c where f' is the shifted frequency of light (at the moment of reception), f is the original frequency (at the moment of emission), c' is the speed of light relative to the observer (at the moment of reception), c is the speed of light relative to the emitter (at the moment of emission).
