There is a photograph of Albert Einstein standing beside the most famous man in the world, who happened to be the great comedian Charlie Chaplin. In 1931, Einstein was touring Los Angeles, and a chance encounter at Universal Studios led to an invitation to attend the premiere of Chaplin’s new movie City Lights. Both men are dressed in tuxedos and smiling broadly. It’s astonishing to think that Einstein was the second-most-famous man in the world.

Einstein’s visuals images began his journey to the Special Theory of Relativity, and for our purposes, that’s critically important. He himself was amazed when his purely mental work turned out to match how nature really works. But everything the theory predicted, including black holes and the slowing of time in the presence of large gravitational forces, has come true. Einstein realized that time, space, matter, and energy were interchangeable.
Nothing is permanent in this wicked world not even our troubles
