Stellar Information Discrepancy in a Newtonian Expanding Universe

Abstract

Since star light carries information, the difference distances of any two stars from the Earth in an expanding universe will cause information discrepancy. Let us consider two such stars α and β for examples where star α is closer to the Earth, then the observer O on the Earth receives much earlier star β’s information than star α’s information. In other words, at the same observer’s time, the observer will receive both stars’ information at different stellar times. But since the universe is expanding, as the observer receives both stellar information at a time, these two stars are already farther away from the Earth. The present paper is to derive how much farther away of the stars from the Earth, that is, the discrepancy in distance.
