对于钻研某些研究的物理学家而言，量子重力论是最后的圣杯，因为除了重力之外，其它的物理都可以用量子定律来描述。

A quantum theory of gravity is a holy grail for a certain breed of physicist because all physics except for gravity is well described by quantum laws.

如果你认为你真正理解重力法则和量子力学，真正很好地理解，那么你可以说，“根据这些定律，宇宙是经脱离而存在的。”

If you think you understand the rules of gravity and quantum mechanics really, really well, you can say, "According to the rules, universes pop into existence."

这就是说，研究环圈量子重力学的理论学家认为无需先作出时空的几何假设，便能表述自然定律。

This means that theorists working on it believe the laws of nature can be stated without making any prior assumptions about the geometry of space and time.
