If confirmed, the recently detected potential ripples from the Big Bang represent an imprint on the cosmic microwave background by gravitational waves. Those gravitational waves are produced through a quantum process, providing, for the first time (again, if confirmed), evidence that gravity is governed by quantum mechanics. This point cannot be overemphasized.
Einstein believed in something like Spinoza's "God": a powerful entity that transcends the world. To Einstein, "God" was the maker of the laws of physics that he, Einstein, saw as his life's role to uncover. This is far from the "God" of organized Western religions, to be sure, but it is equally far from Lawrence Krauss "universe from nothing."
