科技：史上最贵的实验器材—大型强子对撞器
It was supposed to be the greatest science experiment ever, and it’s certainly the most expensive. The large hadron collider designed to recreate the Big Bang theory with colliding particles has so far cost nearly 10 billion dollars and counting. Scientists are hoping to catch sight of the theorized but never seen Higgs Boson particle. The so-called God Particle that gives matter its mass. But within days of kicking off last year the hadron collider broke down. A Helium leak in the cooling system took about a year to repair. And the
