Doppler effect and Cosmology / Red-shift.
=======
The Doppler effect (or the Doppler shift) an increase (or decrease) in the frequency of sound,
light, or other waves as the source and observer move toward (or away from) each other.
/today's knowledge /
=========
a) all galaxies ( . . . . etc ) exist in an infinite vacuum.
If a tree falls in the vacuum, it doesn't make a sound, none would hear this.
This is because sound waves can't travel through an '' empty'' vacuum.
b) in the vacuum, photon with constant speed c has no wavelength. Photon travels with constant speed c is a pure particle, without wavelength.
This pure particle travels in a straight line until it will meet big gravity-masses.
It means, that
it is impossible to use Doppler effect to understand Cosmology and Red-shift.
