 | | Such a theory is required in order to understand those problems involving the combination of very large mass or energy and very small dimensions of space, such as the behavior of fl holes, and the origin of the universe. |
 | | Quantum field theory on curved (non-Minkowskian) backgrounds, while not a quantum theory of gravity, has shown that some of the assumptions of quantum field theory cannot be carried over to curved spacetime, let alone to full-blown quantum gravity. |
 | | Loop quantum gravity is the fruit of an effort to formulate a background-independent quantum theory. |
