Editing Fudge factor (section)

=== Cosmological constant ===
In theoretical physics, when [[Albert Einstein]] originally tried to produce a [[general theory of relativity]], he found that the theory seemed to predict the gravitational collapse of the universe: it seemed that the universe should be collapsing, and to produce a model in which the universe was ''static and stable'' (which seemed to Einstein at the time to be the "proper" result), he introduced an expansionist variable (called the [[cosmological constant]]), whose sole purpose was to cancel out the cumulative effects of gravitation. He later called this, "the biggest blunder of my life".<ref>{{citation |url=https://books.google.com/books?id=UM2agAdvbXkC&pg=PA246 |title=The Quantum World: Quantum Physics for Everyone |author=Kenneth William Ford
