Quantum gravity theory and quantum cosmology are simply reviewed and their logical relations are discussed.

本文对量子引力理论和量子宇宙学作了简单述评，讨论了两者之间的逻辑关系。

This could be achieved by finding which one is right and which one is wrong, by finding that both string theory and loop quantum gravity are wrong and a third theory is right, or by finding that the two theories can be unified.

ECONOMIST: A new ��theory of everything�� is gaining ground

And we might be provided with clues that reveal the trail to unraveling the ultimate holy grail of fundamental particle physics -- a quantum theory of gravity.

CNN: Higgs and the holy grail of physics

With a quantum theory of gravity, we may be able to trace the Big Bang expansion back to its very beginning, and understand precisely how our universe arose, presumably from nothing.
