The cosmos would consist solely of a uniform and tenuous mixture not so very different from air. Say goodbye, to chemistry as we know it, and to life. If it did not, the oceans would freeze from the bottom up and earth would now be covered with solid ice. This property in turn is traceable to unique properties of the hydrogen atom. A remarkable feature of the universe is its emptiness.
Stars are extraordinarily distant from one another.
However, were it not for these vast reaches of empty space, violent collisions between stars would be too frequent as to render the universe uninhabitable. In a finite universe filled with life, some life form has to be the Most High Life Form. If the universe is infinite, than everything that can happen, has happened. Copyright 1998 Elizabeth Hensley.
