"Now the word beautiful is probably overused in physics. I probably overuse it. But I don’t think there is any scientist who would disagree with its use in the context of Einstein’s Theory of Gravity. Because here is a theory that describes a universe that is bent and curved out of shape by every moon, every star, and every galaxy in the sky. And everything in the universe has to follow those curves; from the most massive black hole to the smallest piece of dust, even to beams of light. But the most tantalizing part of Einstein’s Theory of Gravity is that we know it is not complete, we know that it is not the ultimate description of the structure and shape of the universe. And that for a scientist is the most beautiful place to be, on the border between the known and the unknown. That is the true wonder of the universe. There is so much more left of it to explore."
