顾名思义，环圈量子重力可以想象成一个由环组成的网。
Loop quantum gravity can be visualised, as its name suggests, as a mesh of loops.
这种时空的颗粒性源于超弦理论与环圈量子重力学的最重要差异。
This granularity emerges from what is the most important difference between the two theories.
事实上，研究环圈量子重力学的理论学家认为，物质本身不过是时空纽带扭曲缠绕而成的编织物。
Indeed, theorists working on loop quantum gravity think that matter itself is merely the result of twisting and braiding ribbons of space-time.
物质在奇异点被压扁时发生了什么事，取决于量子重力理论的细节，这理论目前尚不清楚。
What happens to matter as it gets squished together at the singularity depends on the details of quantum gravity, which are as yet unknown.
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.
这个超弦理论的对头叫做“环圈量子重力学”，于1986年由宾西法尼亚州立大学的Abhaya shtekar提出。
Loop quantum gravity, as this rival is known, was dreamed up in 1986 by Abhay Ashtekar, of Pennsylvania State University.
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."
“我们仍然需要测试重力在亚原子，量子级别的影响，”他说。
"We still have to test how gravity behaves at a sub-atomic, quantum level," he said.
但现在，澳大利亚墨尔本大学的ArchilKobakhidze提出了这一推断的最致命的问题——重力如何影响量子。
But today, Archil Kobakhidze at The University of Melbourne in Australia points to a serious problem with this approach. He naturally asks how gravity can influence quantum particles.
同样，量子理论很好工作在原子的距离，但已与重力问题。
Similarly, the quantum theory works quite well at atomic distances, but has problems with gravity.
“重力理论和量子理论解释了为什么宇宙可以从无到有自发的创造自己”。霍金告诉King。
"Gravity and quantum theory cause universes to be created spontaneously out of nothing," Hawking told Larry King.
环圈重力将这个见解援引至量子领域。
惊人的后悔是霍金的尝试的结果在一个量重力的强有力的新理论里把广义相对论与量子理论结合起来。
The remarkable about-face is the result of Hawking's attempts to combine quantum theory with general relativity in a powerful new theory of quantum gravity.
也就是说，突变观点和传统观点下，重力对量子的影响是不同的。这需要实验来验证。
In other words, the emergent and traditional views of gravity make different predictions about the gravitational force a quantum particle ought to experience.
