This year's Nobel prize for physics has been won by American and Australian scientists for discovering that the universe is expanding faster than previously thought. The Nobel Committee said the team's findings came as a complete surprise, as one of the winners, Professor Brian Schmidt explains.
今年的诺贝尔物理奖获得者是美国和澳大利亚科学家,他们发现宇宙膨胀比之前认为的要快。诺贝尔奖委员会声称该小组的发现是一个彻底的惊喜,获奖者之一Brian Schmidt教授解释说:
"The fact that we were getting an answer that was exactly the opposite of speeding up and that the universe should not be speeding up was pretty perplexing, and so it was a very bit of trepidation that we ended up telling our group and then eventually telling the world that we have this crazy result: the universe seems to be speeding up."
“我们之前得到的答案恰恰与宇宙在加速这一观点相反,我们曾以为宇宙不可能在加速,得出这样的结论真是令人费解。我们有点惶恐不安地告诉小组,最后告诉全世界这个令人疯狂的结果:宇宙看起来在加速膨胀。”
