In 1915 Einstein introduced the field equation that placed into balance and found equal the [[Curvature of space|curvature]] at one side and mass on the other. He hoped that the equations of [[general relativity]] would determine a single universe model without any beginning or end. For reasons he could never make clear, he found universe so conceived particularly satisfying and he managed to find a solution to his own equations that specified universe of that sort, static and unchanged forever.<ref name="Devils"/>{{#tag:ref|The contemporary atheistic scientists such as [[Stephen Hawking|S.Hawking]] believe there is no room for creator in the universe which has no boundary or edge whereas in universe which had beginning we could suppose it had a creator.<ref name="WhomadeGod">{{cite book
