Static
universe > Albert Einstein (1789-1955), conscientious of the importance of the
theory of the relativity generalized in the cosmological research, looked for to develop
equations that explained the universe. Its first article on the subject was in 1917, when it displayed a model cosmological of the new age: a static, homogeneous universe, not limited, but finite. So that its relativistas equations if applied to one such universe, Einstein was obliged to introduce of this constant the most beautiful error of its life. For the time, such works so seemed
moved away from the astronomical comments that were
considered diversion for the mathematicians. In Russia in 1922, a young theoretician, the meteorologista Alexander Friedman (1888-1925) - It showed that the equations of general relativity did not admit an only solution, but a set. When discovering an error in its
proper exposition, Einstein classified the result of Friedman as elucidative. The enormous speeds of removal of nebulas, determined for Slipher in 1914, implied a problem of as to explain that so fast objects remained in the interior of the galaxy. The theory of the Big Bang was given in 1929 when Hubble registered that the neighboring galaxies the Way Láctea if moved away, suggesting that in fact the expansion of the universe was observável, but the proper astronomer considered mere hypothesis.
