美國粒子對撞機驗證反物質存在

US particle physicists are inching closer to determining why the Universe exists in its current form, made overwhelmingly of matter.
美國的粒子物理學家在探索爲何現行的宇宙主要由正物質組成的過程中又進了一步。

Physics suggests equal amounts of matter and antimatter should have been made in the Big Bang.
物理學家認爲等量的正物質和反物質應該在宇宙大爆炸的過程中形成。

In 2010, researchers at the Tevatron accelerator claimed preliminary results showing a small excess of matter over antimatter as particles decayed.
2010年，研究人員在粒子對撞機的初步試驗中發現在正物質粒子衰變的過程當中有少量的反物質出現。

The team has submitted a paper showing those results are on a firmer footing.
這個研究團隊已經發表了一篇論文來說明這個試驗結果的真實性。

Each of the fundamental particles known has an antimatter cousin, with identical properties but opposite electric charge.
物理學家認爲任何的基礎物質都有一個反物質“表兄”，反物質與正物質的擁有一致的物理特性，但是帶有完全相反的電性。

When a particle encounters its antiparticle, they "annihilate" each other, disappearing in a high-energy flash of light.
當一個粒子遇到它的反物質的時候，他們會湮滅彼此，同時放出奪目的高能閃光。
