Einstein was among the earliest to propose that such a unified field theory must exist, and he struggled -- without success -- for most of his later life to find the right theory. Today we may be on the verge of realising Einstein's dream. String theory is currently the most promising example of a candidate unified theory. We are not yet sure that it correctly describes nature, but it broadly describes a world similar to ours, and is endowed with beauty and consistency to an astonishing degree. |
