我们提出的论点表明，将克尔解的负质量部分解释为代表反物质所经历的几何是很自然的。对于这种几何，考虑了C、P和T离散变换。所提出的识别的C和T性质与反物质的通常表示是一致的。此外，我们通过克尔虫洞推测了一种完美污名的性质，它允许广义相对论模拟反重力。然后，克尔虫洞就会起到“超级镜子”的作用，颠倒透过它看到的物体的C、P和T图像。这一解释经受了几次实验检验，并能够在没有任何自由参数的情况下解释在中性介子系统中观察到的‘CP’破坏。
We present arguments showing that it is natural to interpret the negative mass part of the Kerr solution as representing the geometry experienced by antimatter. The C, P and T discrete transformations are considered for this geometry. The C and T properties of the proposed identification are found to be in agreement with the usual representation of antimatter. In addition, we conjecture a property of perfect stigmatism through Kerr wormholes which allows General Relativity to mimic antigravity. Kerr wormholes would then act as ''super-mirrors'' reversing the C, P and T images of an object seen through it. This interpretation is subject to several experimental tests and able to provide an explanation, without any free parameter, of the ''CP'' violation observed in the neutral kaon system.
