事实上，这些胆小鬼(弱相互作用大质量粒子)不与自己在同一交互方式“正常”的事一样。
In fact, these WIMPs (Weakly Interacting Massive Particles) do not interact with themselves in the same way that "normal" matter does.
对这些正电子有一个可能解释，就是它们来自同一种暗物质以正、反物质形式出现的一对粒子的碰撞（物质湮灭），这样的暗物质又被称为“大质量弱相互作用粒子”（WIMP）。
One possible explanation for these positrons is the mutual annihilation of the matter and antimatter forms of a type of dark matter called weakly interacting massive particles, also known as WIMPs.
WIMP即大质量弱相互作用粒子，是暗物质理论最主要的候选者。WIMP产生于大爆炸中，自产生后一直聚集、散开形成星系。
The leading candidate is a WIMP, or weakly-interacting massive particle, that was produced in the big bang and has been clumping up and seeding structures such as galaxies ever since.
