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Abhay a shtekar提出。

Loop quantum gravity, as this rival is known, was dreamed up in 1986 by Abhay Ashtekar, of Pennsylvania State University.

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.

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.
