So far it seems to be working : the infinities that plague other theories of quantum gravity have been tamed , and the theory spits out a well-behaved graviton .

到目前为止，它看起来是有效的：让其他量子引力理论苦恼的无穷大已经不成问题，并且该理论给出一种功能良好的引力子。

Try and work out the gravitational force between two objects in terms of a quantum graviton , however , and you quickly run into trouble-the answer to every calculation is infinity .

但是尝试用量子引力子解决两个物体之间的万有引力，你很快会遇到困难每种计算的答案都是无穷大量。

Generally these attempts tried to " quantize gravity " by positing a particle , the graviton , that carried gravity in the same way that photons ( light ) carry electromagnetism .

一般来说，这些尝试通过假设一种粒子来“量化”引力，这种粒子被称为“引力子”，引力子如同光子携带电磁力一般携带引力。
