>>19164212Albert Einstein developed the theory of relativity as a static universe cosmology on the basis of no observations whatsoever because he was an atheist and a communist and static universe cosmology was part of his contribution to atheist communist political propaganda.
After his atheist political propaganda relativity theory was disproved by Hubble's discovery of the apparent distance to redshift relationship observed in galaxies, Einstein changed his theory in order to fit the observable evidence, but he never changed his views on atheism or communism even though his big argument for atheism was also debunked by Hubble.
