SELFPROOF 0606 - BLUESHIFT

• BLUESHIFT is any decrease in wavelength, with a corresponding increase in frequency, of an electromagnetic wave; the opposite effect is referred to as redshift. In visible light, this shifts the color from the red end of the spectrum to the blue end. (Wikipedia - 14 Jul 2016)

• 0602-01:   That a photon converging on another object is being blue gravityshifted and thus is able to maintain lightspeed.
• 0602-03:   That a photon moving from a lower dynamic mass gravitonstream to a higher dynamic mass gravitonstream is being blue gravitonstreamshifted and is thus able to maintain lightspeed.

• The rearward gravitypull the photon has experienced during its lifetime.
• The forward gravitypull the photon has experienced during its lifetime.
• The energy the photon has absorbed during its lifetime.
• The energy the photon has ejected during its lifetime.

• The mass of the emitting object (strictly, the emitting object is most likely to be an atom but to keep thing simple it can be said to be the galaxy, star, or whatever it is that contains the atom).
• The direction of emission (photons always move at lightspeed so a photon emitted to the fore of a moving object suffers the gravitypull of the emitting object for longer than does one emitted to the rear). 
• The mass of the absorbing object (strictly, the absorbing object is the detector here on Planet Earth but, especially if it is an extragalactic photon, the detector's position within the Milky Way needs to be taken into account - thus the mass measure need is the mass of the Milky Way modified by the position of the Earth in one of its spiral arms, modified by the position of the detector here on Earth).
• The direction of absorption (photons always move at lightspeed so a photon absorbed to the fore of a moving object suffers the gravitypull of the absorbing object less than does one absorbed from the rear).
• The distance of the emitting object from the Ucentre at the time of emission.
• The distance of the absorbing object from the Ucentre at the time of absorption. 
• The altering gravitypull of the Universe as a whole as it expands and thus becomes less dense.
• The differential colourshifting experienced by a photon during its lifetime from "flyby's" of massive objects (since all objects are moving, the measures of redshift and blueshift that result from a flyby rarely cancel each other out).
• The effect of the gravitonosphere gravitonstreams through which photons move during their lifetime (gravitypull strength is an absolute and is thus easily predictable if all the factors are known whereas the speed and direction of a gravitonstream can vary dramatically over a short distance).

• The colourshift of a photon is the sum of the redshifting and blueshifting it has suffered during its lifetime.
• The farther an object is from Planet Earth, the more massive it must be for meaningful numbers of its photons to be detectable and thus they are more likely to be redshifted than blueshifted.
• Planet Earth is a considerable distance away from the gravitoncore of the Milky Way which is a relatively small mass galaxy - thus the blueshifting of an extragalactic photon as it travels between the Milky Way's gravitysheath interface and the Earth will be unlikely to cancel out the photon's previous redshifting. 
• The Universe is expanding so the distance of most objects from the Ucentre was once less than Planet Earth's current distance from the Ucentre. Thus all extragalactic photons will have some degree of redshift by the time they reach Earth and photons emitted during the early life of the Universe will have a marked redshift.
• In the early life of the Universe, gravitonstream speeds were extremely high resulting in the extreme redshifting of newly stabilised photons.
