21. The classical cosmology is based on Albert Einstein's General Theory of Relativity ( GTR ). 22. The theory, now called the general theory of relativity , which considers all observers to be equivalent. 23. Einstein thus became an overnight celebrity, and his general theory of relativity revolutionized physics and cosmology. 24. Einstein's general theory of relativity , Planck's quantum mechanics and Heisenberg's uncertainty principle all came out of Berlin. 25. In 1930 MacKaye startled the world after announcing an alternative to Albert Einstein's General theory of relativity . 26. In 1917, Einstein applied the general theory of relativity to model the large-scale structure of the universe. 27. :I personally think that one of the best books is General theory of relativity by Paul Dirac. 28. In this way, general theories of relativity are supposed to also eliminate the strict distinction between noninertial frames. 29. In Einstein's general theory of relativity , gravity and space are not separate concepts, but work hand in glove. 30. The absolute differential calculus, later named tensor calculus, forms the mathematical basis of the general theory of relativity .
