31. According to relativity theory , that stirring action should send out a weak signal of gravitational waves. 32. Nevertheless, he managed to write three outstanding papers, two on relativity theory and one on quantum theory. 33. As the article the OP linked states : " Relativity theory depends on " reference frames ". 34. The space-time concept in relativity theory , itself is a derived one and it needs its own definition. 35. In the special relativity theory , too, proper time elapses differently for clocks moving relatively to each other. 36. Because gravity waves are predicted by Einstein's relativity theory , physicists would hail their detection as a major coup. 37. It could not serve as a universal reference medium, as this would be contrary to relativity theory ." 38. Relativity theory came in two parts.39. If relativity were invented today, perhaps it would be called " relativity theory " just for looking good! 40. He also derived the transformation equations which formed the basis of the special relativity theory of Albert Einstein.
