"If physicists had a holy grail it would go by the name of Quantum Gravity."

"For 60 years researchers have been searching for a way to unite the very large and the very small into a single coherent theory. But for all their efforts, Einstein's Theory of General Relativity — which describes the Universe at large scales — simply won't play nice with quantum physics — the all-encompassing vision of the micro-world. But the appearance of a remarkable new idea is raising eyebrows, and hopes, around the world. Maybe, just maybe, a new clue to the most fundamental of fundamental theories has been found."

"It all begins with the weirdest weirdness of quantum physics."

"Quantum mechanics was developed more than a century ago to explain the behavior of the atomic domain. Using their instruments to probe to ever-smaller scales, physicists 100 years ago found that the sub-atomic world behaves quite differently than our own. The list of quantum weirdness is long and includes things like intrinsic uncertainties and electrons existing in two places at once."
