:<math>F_N=GMm/r^2</math>
:<math>F_N=GMm/r^2</math>
Of course I "knew" that the universe is expanding and speed of expansion (called [[Hubble constant]])

is about 70km/s/Mpc. I also new that photons interact with masses in the universe that have to influence those photons slightly diminishing their momentum. All this was "known". What was not known was how much of their momentum photons lose flying through the universe, due to the presence of matter in the universe. I tried to calculate it approximately but got the results always between zero and infinity depending on my approximations, which obviously ment that my approximations were wrong.

In February 1985 I decided that it is crazy not to be able to calculate such a simple thing. I decided not to use any approximations this time and I calculated, with high school calculus, Newtonian math, and a little of Einsteinian physics (limited to equation <math>E=mc^2</math>) how much of cosmological [[redshift]] in the universe is due to the expansion of space and how much is due to the Newtonian interaction between photons and the masses of universe that as I learned from Ned Wright <ref>Edward L. (Ned) Wright, Astronomy
