So the condition for a theory in which the infinities .

那么理论上无穷大的情况。

Because you can get infinitely close to a point , the forces acting on it can become infinitely large , and scientists hate infinities .

因为，你可以无限趋近一个点，其上的力也能变得无限大，科学家对无限大很无奈。

The ieee 754 standard provides for the definitions of floating-point infinities , negative infinities , negative zero , and nan ( not a number ) .

ieee754标准提供了浮点数无穷，负无穷，负零和非数字（notanumber，简称nan）的定义。

He also showed how one can make sense of adding and multiplying infinities .

他还演示了如何能理解将各种无穷大相加和相乘。

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。
