英语听力：自然百科 Atom Smasher Safe 粒子对撞实验可能毁灭地球？

 The most powerful atom smasher ever built could make some bizarre discoveries, such as new forces of nature or even extra dimensions of space, after it's switched on in August.

 

The Large Hadron Collider, or LHC, basically consists of a ring of supercooled magnets 17 miles in circumference¹ attached to huge barrel-shaped detectors². The ring which straddles the French and Swiss borders at the CERN center is buried 330 feet underground. But some have fears. Will it spawn³ a black hole that could swallow Earth or spit out particles that could turn the planet into a hot dead clump⁴?

 

LHC is only going to reproduce what nature does every second and has been doing for billions of years, and all those astronomical⁵ bodies including the Earth and the Sun. They are still here. So though there really is no problem, but okay, if people are concerned about it, we'll certainly discuss (it).

 

The safety of the collider, which will generate energies 7 times higher than its most powerful rival at Fermi National Accelerator Laboratory here in Chicago, has been debated for years.

 

When you collide two particles, it nearly seems like colliding two mosquitoes. These will be incredibly small black holes with no more energy than a mosquito. Very likely these things are not going to be made at all. If they are made, then they’re surely going to decay.

 

A lawsuit⁶ was filed against CERN and its US partners in a Hawaiian court on March 21st, but a ruling has yet to be made.

 

I think obviously we have no concern at all. There is a huge community of scientists who know what they are talking about and are sleeping quite soundly concerning LHC. But nevertheless this creates problems in the general public where LHC is concerned and we have to answer to that.

 

The machine, which has been called the largest scientific experiment in history, isn't expected to begin test rounds until August, and ramping⁷ up to full power could take months.
