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。
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.
l 牛顿指出，两个物体距离越远、质量越小，他们之间的引力也越弱。
The further apart and the lighter two objects are, the weaker is the pull of gravity between them.
万有引力定律是任何两个物体之间都存在相互作用的引力。
The law of universal gravitation is that existence all interacts between any two objects gravitation.
