Is the universe and cosmos mostly designed out of diversity or unity? Clearly, the universe is made up of similar galaxies and dissimilar radiation. But is it a single universe composed of many objects or is it just many objects having different properties? Since we cannot observe the universe, what is our concept of it? Here, the problem is to find a One or Many concept of the universe. While some cosmic theories are "one" (unity), others are "many" (diversity). The Big Bang theory predominates but has many competing "one" and "many" theories. The problem of the Big Bang theory, or of any cosmic theory, is that we cannot identify a concept Universe which is identical or similar to the manner we obtain a concept of a turtle.
