美国粒子对撞机验证反物质存在
US particle physicists are inching closer to determining why the Universe exists in its current form, made overwhelmingly of matter.
美国的粒子物理学家在探索为何现行的宇宙主要由正物质组成的过程中又进了一步。
Physics suggests equal amounts of matter and antimatter should have been made in the Big Bang.
物理学家认为等量的正物质和反物质应该在宇宙大爆炸的过程中形成。
In 2010, researchers at the Tevatron accelerator claimed preliminary results showing a small excess of matter over antimatter as particles decayed.
2010年，研究人员在粒子对撞机的初步试验中发现在正物质粒子衰变的过程当中有少量的反物质出现。
The team has submitted a paper showing those results are on a firmer footing.
这个研究团队已经发表了一篇论文来说明这个试验结果的真实性。
Each of the fundamental particles known has an antimatter cousin, with identical properties but opposite electric charge.
物理学家认为任何的基础物质都有一个反物质“表兄”，反物质与正物质的拥有一致的物理特性，但是带有完全相反的电性。
When a particle encounters its antiparticle, they "annihilate" each other, disappearing in a high-energy flash of light.
当一个粒子遇到它的反物质的时候，他们会湮灭彼此，同时放出夺目的高能闪光。
