1.Because Einstein thought he needed to model a staticuniverse, he introduced his “cosmological fudge factor” to balance the attractive gravity of matter.
2.These three prejudices led Einstein to introduce the cosmological term to construct a static solution that was finite and yet had no boundaries—his universe curved back on itself like the surface of a balloon [see illustration on page 74].
3.However, when Edwin Hubble found that our universe was expanding in 1926, physicists lost there interesting on this static homogeneous cosmological model.
