SELFPROOF 0608 - DOPPLER
COLOURSHIFTING
CURRENT COSMOLOGY MODEL
The
Doppler effect is the change in frequency of a wave for an observer
moving relative to the source of the wave. The Doppler effect for
electromagnetic waves such as light is of great use in astronomy and
results in either a redshift or blueshift. Doppler colourshifting has
been used to measure the speed at which stars and galaxies are
approaching or receding from us. The use of Doppler colourshifting in
astronomy depends on our knowledge that the spectra of stars are not
continuous. They exhibit absorption lines at well defined
frequencies. Doppler colourshifting is recognisable in the fact that
the absorption lines are not always at the frequencies that are
obtained from the spectrum of a stationary light source. (Wikipedia

MALTA COSMOLOGY TEMPLATE
- A photon converging on another object is blue gravityshifted. (see Argument 0606)
- A photon diverging from another object is red gravityshifted. (see Argument 0607)
COMMENTARY
Gravitational
colourshifting is complicated by a Doppler Effect which occurs when the
photon emitting object and the photon receiving object are converging
on each other or diverging from each other. Consider the following
examples:
- Galaxy A and Galaxy B are diverging.
- They
are adjacent and of equal mass, with each having a gravitysheath diameter of
200,000 lightyears.
- Photons
are emitted at the galactic core of Galaxy A and received at the
galactic core of Galaxy B.
- Because
the two galaxies are diverging a photon travelling between the two
spends less time in the gravitysheath of Galaxy A being
redshifted than it does in the gravitysheath of Galaxy B being
blueshifted.
- Thus it is received at Galaxy B with a net doppler blueshift.
- Galaxy A and Galaxy B are converging.
- They are adjacent and of equal mass, with each having a gravitysheath diameter of 200,000 lightyears.
- Photons are emitted at the galactic core of Galaxy A and received at the galactic core of Galaxy B.
- Because
the two galaxies are converging a photon travelling between the two
spends more time in the gravitysheath of Galaxy A being redshifted than
it does in the gravitysheath of Galaxy B being blueshifted.
- Thus it is received at Galaxy B with a net doppler redshift.
Every photon emitting object in the Universe is moving relative to every
photon receiving object. Thus there is always some degree of
divergence or convergence. Thus any gravitational colourshift is always altered by some degree of doppler colourshifting.
Whether the doppler colourshifting is enough to be directly
measurable with our present equipment is another matter.
