"Everything is being compressed into tiny tablets. You take a little pill of news every day - 23 minutes - and that's supposed to be enough." -Walter Cronkite, RE TV news. The Web has changed that for many, however, and here is an extra dose for your daily news cocktail. This prescription tends to include surveillance and now war-related links, along with the occasional pop culture junk and whatever else seizes my attention as I scan online news sites.:: 9.05.2008 ::
:: Apocalypse Not: Atom-smasher won't doom planet, says study ::
PARIS (AFP) — People who fear a powerful atom-smashing machine, due to start operations next Wednesday, will cause Earth to be gobbled up or reduced to grey goo can rest assured, according to a study released Friday.
The Large Hadron Collider (LHC) has been shadowed by Internet-fuelled concerns that it will release energies so powerful that it will create a runaway black hole that will engulf the planet, or a "strangelet" particle that would transform Earth into a lump of strange matter.
But the new report says these fears are unfounded.
It says the LHC will replicate collisions that already occur naturally when Earth runs into the path of high-energy cosmic rays.
"Nature has already conducted the equivalent of about a hundred thousand LHC experimental programmes on Earth -- and the planet still exists," it says.
The assessment is written by five physicists at LHC's operator, the European Organisation for Nuclear Research (CERN) in Geneva.
They had been asked by CERN to take a fresh look at a safety assessment written by CERN scientists in 2003 that also gave the project the green light.
The LHC, installed in a 27-kilometre (16.9-mile) tunnel on the French-Swiss border, is to start unleashing a beam of protons next Wednesday in the first stage of its commissioning process.
Two parallel beams of particles, one going clockwise and the other anti-clockwise, will blast around the underground ring.
At four locations on the ring, superconducting magnets will bend the beams so that groups of protons smash into each other in a giant chamber which is swathed with detectors to record the resulting sub-atomic debris.
This invisible rubble could help resolve some of the biggest questions in physics, such as the nature of mass, the weakness of gravity and whether, as some theoreticians suggest, there exist dimensions beyond our own.
The new Safety Assessment Report says that any black holes produced by the collider would be "microscopic" and decay almost immediately, as they would lack the energy to grow or even be sustained.
"Each collision of a pair of protons in the LHC will release an amount of energy comparable to that of two colliding mosquitoes, so any black hole produced would be much smaller than those known to astrophysicists," it says.
