Universe

in astronomy, that part of space that contains the heavenly bodies. No dimensions can be assigned, for we do not know the distance of the remotest star now visible, nor do we know what stars may exist in space beyond our field of vision. So far as astronomers have been able to study the sidereal or starry universe, they are of the opinion that nearly all the stars are within a space having the shape of a thin disk or the form of a watch. Our sun appears to be near the center of this astronomical universe. The large stars are distributed rather uniformly, but the smaller stars are clustered or arranged in streams. It is held that the entire stellar universe is revolving about a center of gravity situated in or near the largest star in Pleiades.
