约翰-惠勒和诺贝尔奖得主理查德-弗雷曼，他们基于物理体系中时间应该可以倒流的想法，提出了一种反物质理论。
One theory about why antimatter exists was developed by John Wheeler and Nobel laureate Richard Feynman based on the idea that physical systems should be time-reversible.
反物质的独特发现是理论预示未知世界这一说法的一个极好说明。
The original discovery of antimatter was a nice example of theory predicting an undiscovered fact.
依照物理学的标准理论，反物质宇宙应该看起来与我们自己的宇宙相同。
According to the standard theories of physics, the antimatter universe should look identical to our own.
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.
核科学家们称，他们在探寻反物质方面取得了突破性的进展。反物质是宇宙起源大爆炸理论的一个关键组成部分。

迪拉克理论的极大成功不仅是因为证明了原子结构的微细节，还因为它揭示了物质与反物质的基本对称。
Dirac's theory was not only extremely successful in accounting for the fine details of atomic structure, but also revealed a fundamental symmetry between matter and anti-matter.
物理学家以前在理论中预言了反物质的存在，但这一点直到1932年才在实验中得到证实。
Over the years, physicists have theorized about anti-matter, but it wasn't confirmed to exist experimentally until 1932.
