　　The reason this is important is that Dirac s equation is misleading.

　　狄拉克方程是一种误导这个原因是很重要的一点。

　　Antimatter cannot be the perfect opposite of matter, otherwise neither would exist at all.

　　反物质并不是完全的反物质，否则它将无法存在。

　　If they truly were perfect opposites, equal amounts of the two would have been made in theBig Bang,

　　如果实际上它们是完全相反的，那么相同的数量的反物质早在大爆炸产生时就已经互相湮灭了，

　　and they would have annihilated each other long since, leaving only light and other forms ofelectromagnetic radiation to fill the universe.

　　它们只以电磁波的形式留在宇宙中。

　　That galaxies, stars and planetsand physicists to ponder such thingsexist thereforemeans there is a subtle asymmetry between matter and antimatter, and that naturesomehow favours the former.

　　星系，恒星以及行星物理学家在在仔细思考这样的事情它们都已经存在了，这意味着在物质与反物质之间有着一些不可思议的不对称性，自然界在某种程度上是偏爱于前者。

　　Two such asymmetries have indeed been found. But neither is big enough to explain why somuch matter has survived. Being able to look at entire anti-atoms might give some furtherclue.
