被称作为MOND（修正的牛顿动力学MOND）的理论认为，引力理论并不像近代物理学理论所预计的那样会很快地消逝。
The theory called MOND (modified Newtonian dynamics), suggests that gravity does not fade away as quickly as current theories predict.
给出引力的作用规律和关于物质分布的假设后，下一步是得出宇宙的动力学规律——空间和质量如何与时间相互作用。
Given a law of gravity and an assumption about how the matter is distributed, the next step is to work out the dynamics of the universe - how space and the matter in it evolves with time.
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.
