SELFPROOF 0610 - COSMOLOGICAL COLOURSHIFTING

• Hubble's law (COSMOLOGICAL COLOURSHIFTING) is the name for the observation in physical cosmology that: (1) Objects observed in deep space (extragalactic space, 10 megaparsecs (Mpc) or more) are found to have a Doppler shift interpretable as relative velocity away from Earth; (2) This Doppler-shift-measured velocity, of various galaxies receding from the Earth, is approximately proportional to their distance from the Earth for galaxies up to a few hundred megaparsecs away. Hubble's law is considered the first observational basis for the expansion of the universe and today serves as one of the pieces of evidence most often cited in support of the Big Bang model. (Wikipedia - 18 Jul 2012)

• 0204-02:   That at Moment Zero, because the Universe is 100% dense and its energy is 100% kineticenergy, it must expand.
• 0602-01:   That a photon converging on another object is being blue gravityshifted and thus is able to maintain lightspeed.
• 0602-02:   That a photon diverging from another object is being red gravityshifted and thus is able to maintain lightspeed.
• 0603-01:   That every cosmic photon reaching the Earth today has moved away from the Ucentre and is thus red gravityshifted from the wavelength at which it first stabilised. 

• Gravitational colourshifting - moving the photon toward or away from a gravity source.
• Gravitonstream colourshifting - moving the photon between gravitonstreams that have different dynamic masses.
• Doppler colourshifting - moving the photon toward or away from the observer.
• Cosmological colourshifting - moving the photon toward or away from the Ucentre.

• The gravitational centre of the Universe is at or near the Ucentre (for simplicity, assume it hereafter to be at the Ucentre).
• Every photon, be it a cosmic photon or a stabilisation photon, stabilises at a specific wavelength and at a specific distance from the Ucentre.
• Thereafter it moves toward or away from the Ucentre (perhaps changing from one to the other during its lifetime, perhaps doing so many times).
• In moving toward the Ucentre is it cosmologically blueshifted.
• In moving away from the Ucentre it is cosmologically redshifted. 

• Planet Earth is a specific distance from the Ucentre.
• Extend that distance to be a sphere surrounding the Ucentre.
• Call that sphere "Envelope E".
• Some photon emitting objects are inside Envelope E and others are outside.
• Photons emitted inside Envelope E are cosmologically redshifted when they reach Earth. 
• Photons emitted outside Envelope E are cosmologically blueshifted when they reach Earth. 

• Moment Zero was a notional 13 billion years ago.
• The diameter of the Universe at Moment Zero was a notional 1 billion lightyears.
• Since Moment Zero the Universe has been expanding.
• Going back in time, the proportion of photon emitting objects that are inside Envelope E increases. 
• Before a specific moment back in time, all photon emitting objects are inside Envelope E - and thus all such emitted photons are cosmologically redshifted when they reach Earth.
• Going progressively backward in time, photon emitting objects are progressively farther inside Envelope E - and thus the cosmological redshift of such emitted photons is progressively greater. 

• Young extraterrestrial photons can be cosmologically blueshifted or cosmologically redshifted when they reach Earth.
• The older an extraterrestrial photon is, the more likely it is to be cosmologically redshifted when it reaches Earth.
• Beyond a certain age, all extraterrestrial photons are cosmologically redshifted when they reach Earth. 
• Going progressively beyond that certain age, extraterrestrial photons are progressively more cosmologically redshifted when they reach Earth.
