狄拉克因为发现反物质而赢得了1933年的诺贝尔物理学奖。
Dirac went on to win the Nobel prize in physics in 1933 for his discovery of antimatter.
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.
他们认为他们在宇宙中发现了大量高能量的正电子。正电子是电子的反物质形式。他们推测这也是暗物质存在的一个证据。
They think they have seen an abundance of high-energy positrons, the antimatter versions of electrons, coming from space, and they speculate that this, too, is a sign of dark matter.
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.
他的观点引人注目地得到了证明：反电子不久在实验中被发现，“反物质”概念很快成为物理学的基石。
He was dramatically proved right: the anti-electron was soon discovered experimentally, and shortly after the concept of "anti-matter" became a cornerstone of physics.
实际上“物质”与“反物质”的非对称性已经在两项试验中被发现，但它们的非对称程度还不足以解释为什么会有大量的“物质”存续下来。
Two such asymmetries have indeed been found. But neither is big enough to explain why so much matter has survived.
科学家们发现了反氦——与氦等价的反物质。
同样重要的是，Integral发现双星的密度同样是明显偏心的迹象，在一定程度上与反物质云相关。
Equally importantly, Integral found evidence that a population of binary stars is also significantly off-centre, corresponding in extent to the cloud of antimatter.
发现物质和反物质粒子这样的行为差异也可能最终有助于解释为什么我们的宇宙绝大程度上是由物质构成的。
Spotting such a difference in the behaviour of matter and antimatter particles may also finally help explain why our Universe is overwhelmingly made of matter.
研究人员已经在物质和反物质的性质之间发现了一种不对称，称之为电荷宇称不守恒，可能已经让事物的演化偏向了我们的物质世界这一边。
Researchers have discovered an asymmetry between the behavior of matter and of antimatter, called charge-parity violation, which could have skewed things to our side of the material world.
不过，数十年来，科学家们发现了表明在宇宙空间中存有大量反物质的线索，但是反物质从何而来科学家们还不知道。
Still, for decades, scientists had clues that a vast cloud of antimatter lurked in space, but they did not know where it came from.
