Since the other forces work by exchanging carrier particles, we assume that gravity does too and call the carrier the graviton. 既然其它的力都是通过交换载体粒子来作用,我们假设引力也是如此并且称其载体为引力子。
In general relativity theory, graviton is the massless tensor particle, which results in gravitation action in proportion to the energy. 在爱因斯坦引力理论下,引力子为零质量的张量粒子,它导致了粒子之间存在着正比于能量的引力作用。
