宇宙大爆炸

European scientists say they have set a record for high-energy collisions of protons in the world's largest atom smasher, mimicking conditions close to the "Big Bang" that created the universe.

欧洲的科学家说，他们在世界最大的原子对撞机上创下了高能量质子对撞的最新纪录，模拟创造宇宙的"大爆炸"状态。

Still, atom smasher searches for particles that formed shortly after the Big Bang could shed new light on the universe's mysterious existence -- and make it a bit less strange than it is today.

然而，原子加速器搜寻在大爆炸之后迅速形成的粒子可以对宇宙神秘存在有一个新的了解--并可以使得它不至于比今天这样的奇怪。

3Astrophysicists working with ground-based detectors at the South Pole and balloon-borne instruments are closing in on such structures, and may report their findings soon.

假如那些小热点看上去同预计的一致，那意味着又一科学论说的胜利，这种论说即更完美的大爆炸论，亦称宇宙膨胀说。

The Universe has no spatial boundary according to the standard Big bang model, but nevertheless may be spatially finite.

它也可以从宇宙微波背景辐射是大爆炸刚发生不久所产生出非常稀薄的辐射而证实。

For cosmologist and Perimeter Institute director Neil Turok , the biggest mystery is the one that started it all, the big bang .

There are too many successes for big-bang cosmology to be troubled by these lithium problems, he says.

宇宙的大爆炸理论有着很多很多的成功之处，还不至由这些锂的问题构成麻烦，他说。

Pollard says working with the Amsterdam group is an exciting chance to see back towards the Big Bang that started it all.
