Legal bid to stop CERN atom smasher from 'destroying the world'

The world's biggest and most expensive scientific experiment has been hit by a last minute legal challenge, amid claims that the research could bring about the end of the world. Critics of the Large Hadron Collider - a £4.4 billion machine due to be switched on in ten days time - have lodged a lawsuit at the European Court for Human Rights against the 20 countries, including the UK, that fund the project.

The device is designed to replicate conditions that existed just a fraction of a second after the Big Bang, and its creators hope it will unlock the secrets of how the universe began.

However, opponents fear the machine, which will smash pieces of atoms together at high speed and generate temperatures of more than a trillion degrees centigrade, may create a mini-black hole that could tear the earth apart.

Scientists involved in the project have dismissed the fears as "absurd" and insist that extensive safety assessments on the 17 mile long particle accelerator have demonstrated that it is safe.

The legal battle comes as the European Nuclear Research Centre (CERN), in Geneva, prepares to send the first beam of particles around the machine at the official switch on, on September 10, although it will be several weeks before the first particles are collided together.
