Except graviton , all others particles have been found in experiments 除了引力子外，其他所有粒子皆被实验证实存在。

Apex ? 1 reappears to deltan graviton telemetry 0 . 6 billion km from delta 尖端1号，重新出现在距德尔塔6亿公里的地方。
4.
But in practice , it ' ll be a long time before anyone detects a graviton 不过实际上，人们要探测到引力子将需要很长的时间。
5.
From the macroscopic properties of gravity you can work out what the graviton should be like 从引力的宏观属性，你可以推算出引力子的大致情况。
6.
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。
7.
This feature is very welcome because it precisely matches the properties of the carriers of all known fundamental forces , such as the photon ( for electromagnetism ) and the graviton ( for gravity ) 这项特色是很受人欢迎的，因为它精确地吻合所有已知基本作用力载体（如传播电磁力的光子以及重力的重力子）的性质。
