Something accelerating in a pseudoforce g of 9,81m/s get the speed g*t. "tracking" a photon at speed c give that v=g*s/c, where s is the flown distance, and as I see it in any direction(s) g being const. Redshift z=v/c and z=g*s/c^2. Their result was2,5*10^-15and 10m/s*22,5m/(300*10^6m/s)^2 =2,5*10^-15 ,coincidence? By my understanding this is NO never can be.

As the photon "flies" it flies past the whole earth and its mass distribution at different distances albeit 1m at the time. I have a value (factor) calculated from all (20) earths density layers. This factor decreases fast at altitude but have a value 1,27 to 1,29 [(kg/m)/(kg/m)] at earth surface ks=1,28. This factor is for gravitation calcs. (LEO satellites) and thus spot on for this application, giving z= g*s*ks^2/c^2 =4,0*10^-15for s=22,5m. When a photon fly past a planet it ads up (simplyfies) as past a point mass, not here, different parts of earth have different densities at different angles an distances.One can easily end up calculating 2,5*10^-15 but by no means measure it.The coefficient k decrease with altitude but as it is "related" to the rotational inertia factor it can roughly be calculated for altitude rh compared to surface rs distance from mid earth k=(ks-1)/0,4*rs^2/rh^2 +1 ,at geostationary satellites distance k=1,0034 to 1,004 and at moon dist. 385*10^6m 1,00004 to 1,00005. Ihave a table with better values and based on more exact assumptions .

So what I say is that on earth surface light shifts red z=9,81*s*1,28^2/c^2 =1,79*10^-16 for every meter flight in any direction, andnever go bluer in any direction. I would be interested in "paywall free" measurements of this same or similar experiments.

6.9 Ex. A photon in a earth strength field decaying from ultra blue 100nm to infra red 1000nm get a z value =9, the same as photons from the edge of universe. "Decaying" 5,36*10^-8 z/s give for z=9 at time 170milj. sec. that is 5,3 years. So keeping a photon in a "jar" would age it in no time.
