The talk is designed to present my initial work done in theoretical cosmology. The analysis has two implications, The effect of the motion of the observer induces a certain amount of error in the observational astronomy. The relation of this effect is derived and a need for correction in the position (up to 5% of a degree in angular shift in the coordinates)of cosmic objects is proposed due to our cosmic motion around the Milky Way. As the second implication, the results of the analysis will help us to solve the debate over physical existence of the dark flow and and our motion under CMB dipole with predicted speed 630km/sec. Primary outcomes provide negative results for the validity of Dark flow. If further analysis of cosmic structure follows primary indications (which is the next step of the work) it will be a strong evidence against multiverse concept in modern cosmology.
