Astronomy Quote by Walter Isaacson
““This concept of the cosmos that Einstein derived from his general theory of relativity was elegant and magical. But there seemed to be one hitch, a flaw that needed to be fixed or fudged. His theory indicated that the universe would have to be either expanding or contracting, not staying static. According to his field equations, a static universe was impossible because the gravitational forces would pull all the matter together. This””

A Different Perspective
The static model was later saved by introducing the cosmological constant, showing adjustments can be ad hoc.
