这些实验使用大型强子对撞机,以近光速的速度将微粒粉碎。
A man has opened fire and thrown grenades from a rooftop in the Belgian city of Liege, killing three people in a busy Christmas market before killing himself. More than 120 people were injured. Matt Cole reports.

The central square in front of the Palais de Justice remains cordoned off this evening. The Christmas market is dark and empty, but it was very different this lunchtime. Scores were enjoying a festive shopping experience when the man now named as Nordine Amrani began shooting and throwing explosives. People began running, screaming, children amongst them. Whilst the 33-year-old attacker was known to the police, having previously faced drug and weapons charges, officers say they currently don't know why he carried out this terrible act.
今晚司法宫前的中心广场仍然戒备森严,圣诞市场黑漆漆的,空无一人,与午饭时的情形大相径庭。几十人正在这里享受节日购物,这时一位名叫Nordine Amrani的男子开始开枪并投掷炸药。人们开始叫着跑着,其中还有儿童。警察了解这位33岁的袭击者,他之前受过毒品和武器指控,官方称不知道他为何实施这次可怕的袭击。
