"Still, let's assume that even if Hawking is a genius, he's wrong, and that such black holes are more stable," Landsberg said. Nearly all of the black holes will be traveling fast enough from the accelerator to escape Earth's gravity. "Even if you produced 10 million black holes a year, only 10 would basically get trapped, orbiting around its center," Landsberg said.

However, such trapped black holes are so tiny, they could pass through a block of iron the distance from the Earth to the Moon and not hit anything. They would each take about 100 hours to gobble up one proton.

At that rate, even if one did not take into account the fact that each black hole would slow down every time it gobbled up a proton, and thus suck down matter at an even slower rate, "about 100 protons would be destroyed every year by such a black hole, so it would take much more than the age of universe to destroy even one milligram of Earth material," Landsberg concluded. "It's quite hard to destroy the Earth."

In response to a serious shortfall in its budget that came to light last year, CERN looks set to delay the start-up of its Large Hadron Collider (LHC) by twelve months. The measure is part of a new long-term plan published by the lab’s management, which proposes the transfer of SFr500m – about £210m – from other areas of CERN’s budget to pay for the collider. According to the plan, the LHC would not collide its first protons until April 2007.
CERN delays collider start-up

Wagner, who studied physics and conducted cosmic ray research at the University of California-Berkeley, claims a restraining order on Fermilab and the Energy Department, which helps supply the accelerator's superconducting magnets, would shut down CERN's Large Hadron Collider, the newspaper said. He said CERN hasn't properly addressed concerns that the research conducted at the collider might create a miniature black hole or some other form of matter that might destroy the Earth, the newspaper said.

The LHC, which has been operated by CERN since 1994, aims to create as near as possible conditions which existed in the Universe a trillionth of a second after the Big Bang when particles collided at great speed, thus giving physicists an insight into the Universe's origins. "Researchers will sift the debris from these primordial recreations for clues to the nature of mass and new forces and symmetries of nature," reports the New York Times. The 27-kilometre accelerator built to conduct this experiment on the France-Switzerland border will commence its latest experiments in particle smashing in May
Injunction sought against Large Hadron Collider

The research of Stephen Hawking, Albert Einstein and the physicist Kip Thorne has shown that time travel is theoretically possible, but no-one has yet found a way to produce the energy necessary to keep a "wormhole" open.

The collider tunnel contains two pipes enclosed within superconducting magnets cooled by liquid helium, each pipe containing a proton beam.

Could someone explain please how exactly it works? Is a particle inside the tunnel held by the magnets so it stays in the centre of the 'tube' and doesn't come in contact with the walls?

If so, then if a black hole is created how can it get out of control if it is held safely by the superconducting magnets?

Excuse my ignorance.
