"Einstein first proposed the cosmological constant (not to be confused with the Hubble Constant) usually symbolized by the greek letter "lambda" (L), as a mathematical fix to the theory of general relativity. In its simplest form, general relativity predicted that the universe must either expand or contract. Einstein thought the universe was static, so he added this new term to stop the expansion. Friedmann, a Russian mathematician, realized that this was an unstable fix, like balancing a pencil on its point, and proposed an expanding universe model, now called the Big Bang theory. When Hubble's study of nearby galaxies showed that the universe was in fact expanding, Einstein regretted modifying his elegant theory and viewed the cosmological constant term as his "greatest mistake".
LOL, well I look at it like this: Big Al did all his homework on a chalkboard. The new school has the benifit of equipment the Einstein could only dream about in his day, with computer models, observation and such. Even Hawking has the benefit of being able to revise his theories. One wonders if Al wouldn't have done the same had he had modern resources.
At the time that Einstein worked on his relativity theories, scientists generally believed that the universe was static in size. It was intimidating to go against the establishment idea of an unchanging universe so he dumped the constant from his theory.
Scientists have since come around to the the Biblical idea of a creation event using evidence within God's own creation.
A proof that science works.
