The Large Hadron Collider (LHC), a 27 kilometer (17 mile) long particle accelerator straddling the border of Switzerland and France, is nearly set to begin its first particle beam tests. The European Organization for Nuclear Research (CERN) is preparing for its first small tests in early August, leading to a planned full-track test in September - and the first planned particle collisions before the end of the year.

After 14 years and $8 billion, lawsuits and the occasional exploding magnet, the world’s largest physics experiment seems to be getting close enough to becoming a reality for its participants to plan the opening parties
The Large Hadron Collider, under construction at CERN, outside Geneva, is designed to accelerate protons to energies of seven trillion electron volts and then smash them together in search of new particles and perhaps new forces of nature. Although no schedule has been officially announced, sources in the physics community and CERN’s own Web site indicate that scientists and engineers will try to shoot the first beam of protons through one section of 17-mile-long racetrack on the weekend of Aug. 9. If all goes well, the first protons will begin circulating around the entire machine on Sept.2 or 3
After that, the engineers estimate that it will take one or two months of tweaking and ratcheting up the intensity of the beams before they begin colliding and producing “pilot physics.” The initial collisions will be at five trillion electron volts apiece because the engineers have not had time to condition the giant superconducting magnets that funnel the protons around the racetrack to produce fields strong enough to bend seven-trillion-electron volt protons
CERN shuts down the accelerators for the winter to save on electricity costs, so the magnets will be “trained” for the higher energies then. In the meantime the armies of physicists that have built the machine’s two giant detectors, called Atlas and C.M.S., have planned start-up parties in October, and CERN is planning a big event on Oct.21

You can sleep easy in the knowledge that the world's most powerful particle smasher, the Large Hadron Collider, will not gobble us all up in the middle of the night. So says a new safety assessment released by CERN, the European Organization for Nuclear Research, based near Geneva, Switzerland .
The lab hopes this will quash relentless rumours that the LHC could create Earth-obliterating particles. Favourite examples are mini black holes and ravenous "killer strangelets" that could swallow our planet whole. Not to mention even more devastating vacuum bubbles that might destroy the whole universe.
So concerned are campaigners from Hawaii and Spain that they took out a lawsuit attempting to delay the start up of the LHC until a more thorough safety assessments were completed. It remains to be seen whether they will be satisfied with the new report from the LHC Safety Assessment Group, which reaffirms and extends the conclusions of an earlier safety analysis released in 2003.
These safety analyses are clearly vital. If we create technologies that might cook up oddities completely new to science, experts must investigate whether any of them might be dangerous.
But the universe is much better at doing high-energy experiments than we are. Ultra-high-energy particles whizz around the universe all the time, zapping the Earth, planets and stars. If particle collisions like those at the LHC could spawn devastating mini black holes and killer strangelets, they would have gobbled us all up long before now.

CERN LHC: Press Release
Date Issued: 20 June 2008
Geneva, 20 June 2008. At its 147th meeting in Geneva today, the CERN Council heard news on progress towards start-up of the laboratory's flagship research facility, the Large Hadron Collider (LHC). Commissioning of the 27-kilometre LHC began in January 2007 when the first cool down of one of the machine's eight sectors began. Today, five sectors are at or close to their operating temperature of 1.9 degrees above absolute zero and the remaining three are approaching that temperature. Once all sectors are cold, electrical testing will be concluded in readiness for first beams, currently scheduled for August.
"The accelerator, detectors and computing are all on course," said CERN Director General Robert Aymar, "and we are looking forward to the earliest possible LHC start-up."

IN WALKER PERCY’S Love in the Ruins, the protagonist, a doctor and an inventor, recites what he calls the scientist’s prayer It goes like this:
"Lord, grant that my work increase knowledge and help other men
"Failing that, Lord, grant that it will not lead to man’s destruction
"Failing that, Lord, grant that my article in Brain be published before the destruction takes place"
Today we require more than prayers that a scientific experiment will not lead to the end of the world We demand hard-headed calculations But whom can we trust to do them?
That question has been raised by the impending startup of the Large Hadron Collider It starts smashing protons together this summer at the European Center for Nuclear Research, or CERN, outside Geneva, in hopes of grabbing a piece of the primordial fire, forces and particles that may have existed a trillionth of a second after the Big Bang

WILL the world end later this year? In mid-August, in a chamber deep underneath the Swiss-French border, physicists will switch on a machine that might produce the first man-made black holes Normally only found in outer space, these high-gravity objects have a reputation for devouring all matter in their vicinity — and they only stop when the food runs out Could the Earth's first black hole also end up being its last, after it sucks in the chamber, the physicists, and the entire planet?
The possibility has had some press lately because two people are so concerned by this whoops-apocalypse scenario they've taken legal action against CERN, the European agency doing the experiment The two litigants claim researchers haven't done the appropriate risk assessments for this mother of all science experiments
The experiment will be carried out with the most powerful atom-smasher ever built — the Large Hadron Collider.In a few months' time, the machine will push bunches of subatomic particles round and round a 27-kilometre-long ring at almost light speed, and then bring them into a head-on collision Rising from the debris of the impact, according to some theories, could be minuscule black holes
Now, the CERN scientists calculate that the baby black holes' existence will be fleeting. So fleeting, in fact, they'll evaporate almost the instant they form, long before they've had a chance to gobble down the collider or any physicists. (Although they will hang around long enough for measurements to be made, allowing researchers to make some remarkable discoveries about the cosmos.) The physics community says the chance of the particle accelerator inadvertently becoming some sort of doomsday device is almost zero But the interesting thing is, the probability is not exactly zero, so critics argue the possibility can't be ruled out absolutely

Particle Accelerator May Reveal Shape Of Alternate Dimensions
**********************************************************************
ScienceDaily (Feb 4, 2008)
When the world's most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions
Researchers from the University of Wisconsin-Madison and the University of California-Berkeley say that the telltale signatures left by a new class of particles could distinguish between possible shapes of the extra spatial dimensions predicted by string theory
String theory, which describes the fundamental particles of the universe as tiny vibrating strings of energy, suggests the existence of six or seven unseen spatial dimensions in addition to the time and three space dimensions that we normally see
Much as the shape of a musical instrument determines its sound, the shape of these dimensions determines the properties and behavior of our four-dimensional universe, says Gary Shiu, lead author of a paper appearing in the Jan 25 issue of Physical Review Letters

Time travellers from the future 'could be here in weeks'
************************************************************
Telegraph UK
By Roger Highfield, Science Editor
02/06/2008
The first time travellers from the future could materialise on Earth within a few weeks
Physicists around the world are excitedly awaiting the start up of the £465 billion Large Hadron Collider, LHC - the most powerful atom-smasher ever built - which is supposed to shed new light on the particles and forces at work in the cosmos and reproduce conditions that date to near the Big Bang of creation
Prof Irina Aref'eva and Dr Igor Volovich, mathematical physicists at the Steklov Mathematical Institute in Moscow believe that the vast experiment at CERN, the European particle physics centre near Geneva in Switzerland, may turn out to be the world's first time machine, reports New Scientist
The debut in early summer could provide a landmark because travelling into the past is only possible - if it is possible at all - as far back as the point of creation of the first time machine
That means 2008 could become "Year Zero" for temporal travel, they argue
Time travel was born when Albert Einstein's colleague, Kurt Gödel, used Einstein's theory of relativity to show that travel into the past was possible
Ever since he unveiled this idea in 1949, eminent physicists have argued against time travel because it undermines ideas of cause and effect to create paradoxes: a time traveller could go back to kill his grandfather so that he is never born in the first place
But, sixty years later, there is still no fundamental reason why time travellers cannot put historians out of business
But the Russians argue that when the energies of the LHC are concentrated into a subatomic particle - a trillionth the size of a mosquito - they can do strange things to the fabric of the universe, which is a blend of space and time that scientists called spacetime
While Earth's gravity produces gentle distortions in spacetime the LHC energy can distort time so much that it loops back on itself These loops are known to physicists as "closed timelike curves" and they ought, at least in theory, to allow us to revisit some past moment

It's the experiment that could help scientists determine how matter was created at the birth of the universe And it could - just possibly - blow up the Earth
Scientists near Geneva are gearing up to use a 27 kilometre-long circular particle accelerator during 2007
The device - the Large Hadron Collider - at the CERN experimental facility will be used to smash protons into each other at extraordinary speeds, replicating on a tiny scale some of the processes which occured during the Big Bang
News agency Reuters said Brian Cox of Manchester University had told a meeting of the British Association for the Advancement of Science the accelerator could help science better understand the matter that makes up the universe
"We don't know what 95 per cent of the universe is made of - which is a bit embarrassing for a subject that claims to be fundamental," Cox said
"There is dark matter
"It is all over the place but we have no idea what it is"

Safety concerns
Concerns have been raised that performing collisions at previously unexplored energies might unleash new and disastrous phenomena
These include the production of micro black holes, and strangelets (see below). Such issues were raised in connection with the RHIC accelerator, both in the media and in the scientific community.The general response to such fears has been to point out that collisions at these energies have been happening in nature for millennia, as Ultra-high-energy cosmic rays impact Earth's atmosphere and the moon's surface, so if there were any dramatic consequences we would already have seen them by now Another study was commissioned by CERN in 2007 for publication on CERN's web-site by the end of 2007
Micro Black Holes
Though the standard model predicts that LHC energies are far too low to create black holes, some non-standard theories lower the requirements, and CERN itself has published articles that the LHC could create micro black holes at the rate of one per second.According to the standard calculations these are harmless because they would quickly decay by Hawking radiation The concern is that Hawking radiation (which is still debated is a hypothetical form of radiation and these calculations might be wrong, and if micro black holes do not decay they might accumulate inside the earth and eventually devour it
Strangelets
Strangelets are a hypothetical form of strange matter that contains roughly equal numbers of up, down, and strange quarks and are more stable than ordinary nuclei If strangelets can actually exist, and if they were produced at LHC, they could conceivably initiate a runaway fusion process (reminiscent of the fictional ice-nine) in which all the nuclei in the planet were converted to strange matter, similar to a strange star

You can sleep easy in the knowledge that the world's most powerful particle smasher, the Large Hadron Collider, will not gobble us all up in the middle of the night. So says a new safety assessment released by CERN, the European Organization for Nuclear Research, based near Geneva, Switzerland .
The lab hopes this will quash relentless rumours that the LHC could create Earth-obliterating particles. Favourite examples are mini black holes and ravenous "killer strangelets" that could swallow our planet whole. Not to mention even more devastating vacuum bubbles that might destroy the whole universe.
So concerned are campaigners from Hawaii and Spain that they took out a lawsuit attempting to delay the start up of the LHC until a more thorough safety assessments were completed. It remains to be seen whether they will be satisfied with the new report from the LHC Safety Assessment Group, which reaffirms and extends the conclusions of an earlier safety analysis released in 2003.
These safety analyses are clearly vital. If we create technologies that might cook up oddities completely new to science, experts must investigate whether any of them might be dangerous.
But the universe is much better at doing high-energy experiments than we are. Ultra-high-energy particles whizz around the universe all the time, zapping the Earth, planets and stars. If particle collisions like those at the LHC could spawn devastating mini black holes and killer strangelets, they would have gobbled us all up long before now.

CERN LHC: Press Release
Date Issued: 20 June 2008
Geneva, 20 June 2008. At its 147th meeting in Geneva today, the CERN Council heard news on progress towards start-up of the laboratory's flagship research facility, the Large Hadron Collider (LHC). Commissioning of the 27-kilometre LHC began in January 2007 when the first cool down of one of the machine's eight sectors began. Today, five sectors are at or close to their operating temperature of 1.9 degrees above absolute zero and the remaining three are approaching that temperature. Once all sectors are cold, electrical testing will be concluded in readiness for first beams, currently scheduled for August.
"The accelerator, detectors and computing are all on course," said CERN Director General Robert Aymar, "and we are looking forward to the earliest possible LHC start-up."

If you really want to conceal something - hide it in plain sight. This technique is a hallmark of Illuminist groups who are compelled to constantly and robustly protect their hidden knowledge. For over a century, film has been a primary means of deploying the 'hide in plain sight' deception on a mass scale. From the early sci-fi and horror films of European silent cinema to the multi-million dollar Hollywood blockbusters, film has reliably served as a mainline into the belief systems of the populace.A complex alchemy of synchronicity, cultural programming and mind control is used to concurrently deliver both a wash of sensual distraction and a download of unreality tutoring The data from the screen prescribes social tolerances, establishes acceptable behavioural parameters and encodes pre-determined archetypes into the consciousness of the viewer

Critics say the collider experiment is like playing Russian roulette with the planet The chance it could create an Earth-eating black hole is tiny, but what risk is acceptable when the stakes are so

IN WALKER PERCY’S Love in the Ruins, the protagonist, a doctor and an inventor, recites what he calls the scientist’s prayer It goes like this:
"Lord, grant that my work increase knowledge and help other men
"Failing that, Lord, grant that it will not lead to man’s destruction
"Failing that, Lord, grant that my article in Brain be published before the destruction takes place"
Today we require more than prayers that a scientific experiment will not lead to the end of the world We demand hard-headed calculations But whom can we trust to do them?
That question has been raised by the impending startup of the Large Hadron Collider It starts smashing protons together this summer at the European Center for Nuclear Research, or CERN, outside Geneva, in hopes of grabbing a piece of the primordial fire, forces and particles that may have existed a trillionth of a second after the Big Bang

WILL the world end later this year? In mid-August, in a chamber deep underneath the Swiss-French border, physicists will switch on a machine that might produce the first man-made black holes Normally only found in outer space, these high-gravity objects have a reputation for devouring all matter in their vicinity — and they only stop when the food runs out Could the Earth's first black hole also end up being its last, after it sucks in the chamber, the physicists, and the entire planet?
The possibility has had some press lately because two people are so concerned by this whoops-apocalypse scenario they've taken legal action against CERN, the European agency doing the experiment The two litigants claim researchers haven't done the appropriate risk assessments for this mother of all science experiments
The experiment will be carried out with the most powerful atom-smasher ever built — the Large Hadron Collider.In a few months' time, the machine will push bunches of subatomic particles round and round a 27-kilometre-long ring at almost light speed, and then bring them into a head-on collision Rising from the debris of the impact, according to some theories, could be minuscule black holes
Now, the CERN scientists calculate that the baby black holes' existence will be fleeting. So fleeting, in fact, they'll evaporate almost the instant they form, long before they've had a chance to gobble down the collider or any physicists. (Although they will hang around long enough for measurements to be made, allowing researchers to make some remarkable discoveries about the cosmos.) The physics community says the chance of the particle accelerator inadvertently becoming some sort of doomsday device is almost zero But the interesting thing is, the probability is not exactly zero, so critics argue the possibility can't be ruled out absolutely

GENEVA - The father of a theoretical subatomic particle dubbed "the God particle" says he's almost sure it will be confirmed in the next year in a race between powerful research equipment in the United States and Europe
British physicist Peter Higgs, who more than 40 years ago postulated the existence of the particle in the makeup of the atom, said is visit to a new accelerator in Geneva last weekend encouraged him that the Higgs boson will soon be seen
The $2 billion Large Hadron Collider, under construction since 2003, is expected to start operating by June at the European Laboratory for Particle Physics (known as CERN)

Particle Accelerator May Reveal Shape Of Alternate Dimensions
**********************************************************************
ScienceDaily (Feb 4, 2008)
When the world's most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions
Researchers from the University of Wisconsin-Madison and the University of California-Berkeley say that the telltale signatures left by a new class of particles could distinguish between possible shapes of the extra spatial dimensions predicted by string theory
String theory, which describes the fundamental particles of the universe as tiny vibrating strings of energy, suggests the existence of six or seven unseen spatial dimensions in addition to the time and three space dimensions that we normally see
Much as the shape of a musical instrument determines its sound, the shape of these dimensions determines the properties and behavior of our four-dimensional universe, says Gary Shiu, lead author of a paper appearing in the Jan 25 issue of Physical Review Letters

Time travellers from the future 'could be here in weeks'
************************************************************

The first time travellers from the future could materialise on Earth within a few weeks
Physicists around the world are excitedly awaiting the start up of the £465 billion Large Hadron Collider, LHC - the most powerful atom-smasher ever built - which is supposed to shed new light on the particles and forces at work in the cosmos and reproduce conditions that date to near the Big Bang of creation
Prof Irina Aref'eva and Dr Igor Volovich, mathematical physicists at the Steklov Mathematical Institute in Moscow believe that the vast experiment at CERN, the European particle physics centre near Geneva in Switzerland, may turn out to be the world's first time machine, reports New Scientist
The debut in early summer could provide a landmark because travelling into the past is only possible - if it is possible at all - as far back as the point of creation of the first time machine
That means 2008 could become "Year Zero" for temporal travel, they argue
Time travel was born when Albert Einstein's colleague, Kurt Gödel, used Einstein's theory of relativity to show that travel into the past was possible
Ever since he unveiled this idea in 1949, eminent physicists have argued against time travel because it undermines ideas of cause and effect to create paradoxes: a time traveller could go back to kill his grandfather so that he is never born in the first place
But, sixty years later, there is still no fundamental reason why time travellers cannot put historians out of business
But the Russians argue that when the energies of the LHC are concentrated into a subatomic particle - a trillionth the size of a mosquito - they can do strange things to the fabric of the universe, which is a blend of space and time that scientists called spacetime
While Earth's gravity produces gentle distortions in spacetime the LHC energy can distort time so much that it loops back on itself These loops are known to physicists as "closed timelike curves" and they ought, at least in theory, to allow us to revisit some past moment

The experiment that could blow up the planet

It's the experiment that could help scientists determine how matter was created at the birth of the universe And it could - just possibly - blow up the Earth
Scientists near Geneva are gearing up to use a 27 kilometre-long circular particle accelerator during 2007
The device - the Large Hadron Collider - at the CERN experimental facility will be used to smash protons into each other at extraordinary speeds, replicating on a tiny scale some of the processes which occured during the Big Bang
News agency Reuters said Brian Cox of Manchester University had told a meeting of the British Association for the Advancement of Science the accelerator could help science better understand the matter that makes up the universe
"We don't know what 95 per cent of the universe is made of - which is a bit embarrassing for a subject that claims to be fundamental," Cox said
"There is dark matter
"It is all over the place but we have no idea what it is"

Wikipedia: LHC Safety Concerns

Safety concerns
Concerns have been raised that performing collisions at previously unexplored energies might unleash new and disastrous phenomena
These include the production of micro black holes, and strangelets (see below). Such issues were raised in connection with the RHIC accelerator, both in the media and in the scientific community.The general response to such fears has been to point out that collisions at these energies have been happening in nature for millennia, as Ultra-high-energy cosmic rays impact Earth's atmosphere and the moon's surface, so if there were any dramatic consequences we would already have seen them by now Another study was commissioned by CERN in 2007 for publication on CERN's web-site by the end of 2007
Micro Black Holes
Though the standard model predicts that LHC energies are far too low to create black holes, some non-standard theories lower the requirements, and CERN itself has published articles that the LHC could create micro black holes at the rate of one per second.According to the standard calculations these are harmless because they would quickly decay by Hawking radiation The concern is that Hawking radiation (which is still debated is a hypothetical form of radiation and these calculations might be wrong, and if micro black holes do not decay they might accumulate inside the earth and eventually devour it
Strangelets
Strangelets are a hypothetical form of strange matter that contains roughly equal numbers of up, down, and strange quarks and are more stable than ordinary nuclei If strangelets can actually exist, and if they were produced at LHC, they could conceivably initiate a runaway fusion process (reminiscent of the fictional ice-nine) in which all the nuclei in the planet were converted to strange matter, similar to a strange star
