只不过圈量子引力理论把空间分为微小的“构建模块”，而CDT假设空间-时间不是分成微小的构建模块—而是叫做pentachorons的四维的小块。
Just as loop quantum gravity breaks up space into tiny "building blocks", CDT assumes that space-time is split into tiny building blocks - this time, four-dimensional chunks called pentachorons.
量子引力的其它理论，包括弦论和圈量子引力，对新人来说都更难以涉足其中。
Other theories of quantum gravity, including string theory and loop quantum gravity, are far more difficult for newcomers to embrace.
还将这种方法与缠结理论做了比较；要描述圈量子引力的动力学过程，需要新的模型，自旋接网圈的因果演化模型就是其中的一种。
A new model such as the causal evolution model of spin networks is needed to describe a dynamics process of loop quantum gravity.
