"KINETIC WAVES AND RED-SHIFT" contains - until now - ignored- elements of research and results of related applications on the fields of Astrophysics and Cosmology. It is mainly intended to provide more clarity on the origins that gave rise to Theoretical Physics and subsequent cosmological theories that have occurred over the last century, until nowadays. The ground of the present research is formed by in-dept analytical review of the Doppler principle as the original interpretation for the formulation of theories based on the universal constancy of the speed of light. The kinetic-waves model, could become a logical and mathematically sustainable alternative to the classic waves model, which could provide an answer to all the still unresolved problems of some branches of the Physics and the Cosmology.
