Einstein addressIn 1921, Albert Einstein suggested the possibility of measuring the universe, which startled the audience, with his address Geometry and Expansion given at the Prussian Academy of Sciences in Berlin. Applying certain results of the relativity theory, he came to the conclusion that if the real velocities of the stars (as could be actually measured) were less than the calculated velocities, then it would prove that real gravitations' great distances were smaller than the gravitational distances demanded by the law of Newton. From such divergence, the finiteness of the universe could be proved indirectly, and it would even permit the estimation of its size.« |
