Bojowald found he had to create a new mathematical model to use with the theory of Loop Quantum Gravity in order to explore the universe before the Big Bounce with more precision.

波究瓦德发现他必须创建一个新的数学模式来使用循环量子引力理论，以便更加精确地探究大弹跳之前的宇宙。

Other theories of quantum gravity, including string theory and loop quantum gravity, are far more difficult for newcomers to embrace.

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。

Loop quantum gravity is just a set of imaginations, not a theory yet.

这种方案最典型的就是圈量子引力。

This could be achieved by finding which one is right and which one is wrong, by finding that both string theory and loop quantum gravity are wrong and a third theory is right, or by finding that the two theories can be unified.
