当初发现反物质是理论预测未知事实的一个范例，而现在根据反物质的研究发现不对称性的事实则是事实预测了未知理论。

The original discovery of antimatter was a nice example of theory predicting an undiscovered fact. This would be a fact that repaid the compliment by predicting an undiscovered theory.

因此，尽可能准确地在正物质和反物质之间进行比较是很重要的，因为人们迟早会发现某些事情，其中物质和反物质的表现是不同的。

So making comparisons as accurate as you can between matter and antimatter is important, because sooner or later there is going to be found something in which they are different.
