哲学家威廉·詹姆斯曾经说过：“如果你想推翻所有乌鸦都是黑色的定律，你就不能试图证明它们都不是--只要有一只白色乌鸦就足够了”。同样，如果你想测试所谓的CPT定理，根据该定理，由反物质构成的世界与由物质构成的世界的行为完全相同，你不需要创建一个完整的“反世界”。只要证明一个简单反原子中仅有一个跃迁的频率与相应的普通原子中相同跃迁的频率不同，就足够了。
The philosopher William James once said that "if you wish to upset the law that all crows are black, you must not seek to show that none of them are – it is enough to produce a single white crow". Likewise, if you wish to test the so-called CPT theorem, according to which a world constructed of antimatter behaves exactly the same as one constructed of matter, you do not need to create an entire "antiworld". It would be quite sufficient to show that the frequency of just one transition in a simple anti-atom differs from the value of the same transition in the corresponding ordinary atom.
