To be fair, however, m theory does take one important step toward unification by removing the infinities that plagued earlier theories of quantum gravity.
公平的说,M理论的确在大统一理论方面作出了重要的进步,那就是它没有早期量子引力论中灾难性的无穷量。
At such times condemning the market is just like a person who moves forward, regardless of the cliff, and could be draged down by the condemnation of gravity, in a careless step.
这种时候谴责市场,有点象不顾悬崖继续前进的人,在一步踩空之后,谴责重力把他往下拖。

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.
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。
