CERN Scientists Eye Parallel Universe Breakthrough

GENEVA (Reuters) - Physicists probing the origins of the cosmos hope that next year they will turn up the first proofs of the existence of concepts long dear to science-fiction writers such as hidden worlds and extra dimensions.
日內瓦（路透社） - 探測宇宙起源的物理學家希望，明年他們會出現第一次證明有關存在的概念，科幻作家所長期鐘愛的，例如隱藏的世界和額外的維度。
And as their Large Hadron Collider (LHC) at CERN near Geneva moves into high gear, they are talking increasingly of the "New Physics" on the horizon that could totally change current views of the universe and how it works.
及當他們在日內瓦附近的歐洲核子研究中心的大型強子對撞機（LHC）進入高速運轉，他們越來越多談論在地平線上的“新物理學”，那可徹底改變目前對宇宙的看法及它如何工作。
"Parallel universes, unknown forms of matter, extra dimensions... These are not the stuff of cheap science fiction but very concrete physics theories that scientists are trying to confirm with the LHC and other experiments."
“平行宇宙、未知形式的物質、額外的維度 ...這些都不是賤價科幻小說的東西，但具有很堅實的物理學理論，科學家們正試圖以LHC和其它實驗證實。”
This was how the "ideas" men and women in the international research center's Theory Group, which mulls over what could be out there beyond the reach of any telescope, put it in CERN's staff-targeted Bulletin this month.
As particles are collided in the vast underground LHC complex at increasingly high energies, what the Bulletin article referred to informally as the "universe's extra bits" -- if they do exist as predicted -- should be brought into computerized, if ephemeral, view, the theorists say.
Optimism among the hundreds of scientists working at CERN -- in the foothills of the Jura mountains along the border of France and Switzerland -- has grown as the initially troubled $10 billion experiment hit its targets this year.
PROTON COLLISIONS
By mid-October, Director-General Rolf Heuer told staff last weekend, protons were being collided along the 27-km (16.8 mile) subterranean ring at the rate of 5 million a second -- two weeks earlier than the target date for that total.
By next year, collisions will be occurring -- if all continues to go well -- at a rate producing what physicists call one "inverse femtobarn," best described as a colossal amount, of information for analysts to ponder.
The head-on collisions, at all but the speed of light, recreate what happened a tiny fraction of a second after the primeval "Big Bang" 13.7 billion years ago which brought the known universe and everything in it into being.
