When you have to quantify a space, you need a definite unit of measurement. Biblical and Talmudic units of measurement used by ancient Israelites appear frequently within the Scriptures. The original measures of length were clearly derived from the human body: the finger, hand, arm, span, foot, and pace, but, as these measures differ between individuals, they were reduced to a certain accepted standard for general use.

Aberration has been observed in 1727 by the English astronomer James Bradley who, in the course of his surveys, noticed that stars seemed to be subject to a slight movement within a period of one sidereal year. He thought that this movement depended on the position of the star inside the celestial sphere. Read more
