Hi all I want to ask a question about NFE(Newtonian Friedmann Equation).I know that NFE is not usefull to describe universe.But we can have a general idea about universe to use that formula. I know that the only spacial coordinate system is CMB referance frame and NFE is derived from that point(taking RF(Referance Frame) CMB). My question, Is Universe homogeneius and isotrophic somewhere else ? I mean Is there any other point which we can say "Universe homogenic and isotrophic" ? If theres any other point, and we want to calculate NFE(Referance frame will be our new point) it will be also same as NFE (CMB referance frame taken) isnt it ?
