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 .
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 .
