Beauty is the splendor of truth. If we find something that is truly beautiful, then we know that we have found something true. Most of the time, new scientific theories meet with great resistance within the scientific community; it takes a long time for scientists to be convinced of new ideas. But in the case of Einstein’s theory of General Relativity, almost all scientists believed it as soon as they saw it. Even though there was little evidence for it at the time and it had not really been put to the test, most scientists knew that it was right because of its beauty.
