Let me know if there are any errors or holes in my logic, facts, or assumptions. I was thinking in regards to time being relative to the observer and the resulting impossibility of an objective measure of time: In determining the age of the universe, our current estimation is about 13.2 billion years. Now, this would be an estimate or measure based on our earthly frame of reference, the universe being 13.2 billion years old as observed by earthlings. But since any point in the universe can be considered its center, then the 13.2by estimation would result as observed from any other frame of reference in the universe. Therefore, the measure of the age of the earth, as measured in units of time, according to the CMBR is objective and not relative to any frame of reference since every frame of reference is the same. Also, wouldn't this apply to the estimation of the "diameter" of the universe in light years?
