Light’s Traveling & Expectation Page 1 
The 2 Dimension’s Moving Pattern

Suppose that there are 2 similar galaxies and in the same universe (Pic.1)

Planet A is in the galaxy 1, earth is in the galaxy 2

Red Arrow is the light from planet A that we see which is millions of light years away. 

And suppose, when both galaxies move, the length of the Red Arrow doesn't change.

And it will cause the rotation of characteristics to be as in Pic 2

And when it continues the rotating.....The result will be shown as in Pic 3. In other words, there is switching or alternating position.
