Comment on game against West Ham

Cesc came close at least but Rosicky’s finishing is appalling, Hleb never even bothers to shoot, these days Freddie is more likely to score in a nightclub than on the pitch, Gilberto missed an open goal with a header and the one he hit the post with late on was a great chance too. Baptista came on and blundered around and Jeremie Aliadiere came on and showed why in his entire Arsenal career he’s only ever scored one league goal. And that was in 2002 against West Brom

Top Ten Ways To Destroy Earth


Although this is explain scientifically but i do find a sense of humor in it

Method #5

You will need: a black hole, extremely powerful rocket engines, and, optionally, a large rocky planetary body. The nearest black hole to our planet is 1600 light years from Earth in the direction of Sagittarius, orbiting V4641.

Method: after locating your black hole, you need get it and the Earth together. This is likely to be the most time-consuming part of this plan. There are two methods, moving Earth or moving the black hole, though for best results you'd most likely move both at once.

Very difficult, but definitely possible.

Earth's final resting place: part of the mass of the black hole.

Earliest feasible completion date: I do not expect the necessary technology to be available until AD 3000, and add at least 800 years for travel time. (That's in an external observer's frame of reference and assuming you move both the Earth and the black hole at the same time.)

Blackhole

Scientists could generate a black hole as often as every second when the world's most powerful particle accelerator comes online in 2007.

This potential "black hole factory" has raised fears that a stray black hole could devour our planet whole. The Lifeboat Foundation, a nonprofit organization devoted to safeguarding humanity from what it considers threats to our existence, has stated that artificial black holes could "threaten all life on Earth" and so it proposes to set up "self-sustaining colonies elsewhere."

But the chance of planetary annihilation by this means "is totally miniscule," experimental physicist Greg Landsberg at Brown University in Providence, R.I., told LiveScience.

Black holes possible

The accelerator, known as the Large Hadron Collider, is under construction in an underground circular tunnel nearly 17 miles long at the world's largest physics laboratory, CERN, near Geneva.

Black holes are among a handful of threats to the planet. But Earth is more resilient than you might think. >>>

At its maximum, each particle beam the collider fires will pack as much energy as a 400-ton train traveling at 120 mph. By smashing particles together and investigating the debris, scientists hope to help solve mysteries such as the origin of mass and why there is more matter than antimatter in the universe.

If theories about the universe containing extra dimensions other than those of space and time are correct, the accelerator might also generate black holes, Landsberg and his colleague Savas Dimopoulos at Stanford University in California calculated in 2001. Physicists Steve Giddings at the University of California, Santa Barbara and Scott Thomas at Stanford University in California reached similar conclusions.

Black holes possess gravitational fields so strong that nothing can escape them, not even light. They normally form when the remains of a dead star collapse under their own gravity, squeezing their mass together. Although black holes can't be seen, astronomers infer their existence by the gravitational effects they have on gas and stars around them.

Making black holes

A number of models of the universe suggest extra dimensions of reality exist that are each folded up into sizes ranging from as tiny as a proton, or roughly a millionth of a billionth of a meter, to as big as a fraction of a millimeter. At distances comparable to the size of these extra dimensions, gravity becomes far stronger, these models suggest. If this is true, the collider will cram enough energy together to initiate gravitational collapses that produce black holes.

If any of the models are right, the accelerator should create a black hole anywhere from every second to every day, each roughly possessing 5,000 times the mass of a proton and each a thousandth of a proton in size or smaller, Landsberg said.

Still, any fears that such black holes will consume the Earth are groundless, Landsberg said.

For one thing, theoretical physicist Stephen Hawking calculated all black holes should emit radiation, and that tiny black holes should lose more mass than they absorb, evaporating within a billionth of a trillionth of a trillionth of a second, "before they could gobble up any significant amount of matter," Landsberg said.

Not destroyed yet


CERN spokesman and former research physicist James Gillies also pointed out that Earth is bathed with cosmic rays powerful enough to create black holes all the time, and the planet hasn't been destroyed yet.

"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."

If the Large Hadron Collider does create black holes, not only will it prove that extra dimensions of the universe exist, but the radiation that decaying black holes emit could yield clues that help finally unite all the current ideas about the forces of nature under a "theory of everything."

GENEVA (AP)—A 43-foot-long magnet for the world's largest particle collider broke "with a loud bang and a cloud of dust'' during a high-pressure test, and officials said Tuesday they are working to find a replacement part.

The part that failed March 27 was in a super-cooled magnet designed to focus streams of protons so that they collide and allow scientists to study the results of the collision, giving them a better understanding of the makeup of matter, according to Fermilab, based in suburban Chicago, which has an accelerator of its own and is helping build one deep beneath the Swiss and French countryside outside Geneva.

Fermilab, which built the magnet for the 17-mile circular collider, said its teams, working with colleagues from the European Organization for Nuclear Research, have determined what caused the "serious failure'' and are working on a solution.

"It's impossible really to say whether that (schedule) can be maintained at this stage,'' said James Gillies, spokesman for the European group, known by the French initials CERN. But, he added, "everything else is going as if we're still heading for the schedule of this year.''

In a statement posted on its Web site, Fermilab said the failure that broke a glass cloth-epoxy laminate support resulted from a test of "asymmetric'' or irregular force. Subsequent testing showed that the support was inadequate to withstand the longitudinal forces, which had been overlooked in the design process.

Fermilab said it hoped that the redesign and repair can be completed without delaying the startup of the Large Hadron Collider, which has been under construction for years and is being eagerly awaited by scientists around the world.

"We took a pratfall on the world stage,'' said Pier Oddone, director of the lab, which has its own, smaller collider at Batavia, Ill. "We are dumbfounded that we missed some very simple balance of forces.''

The aim of the CERN experiment is to make subatomic particles—in this case protons—travel at nearly the speed of light until they collide, emitting a shower of even smaller particles that will reveal mysteries about the makeup of matter.

There will also be hundreds of other, smaller magnets in the circular tunnel, which is big enough for a subway train and 160-500 feet under the Swiss-French border, CERN said.

The $1.8 billion collider is replacing a less-powerful model that was removed from the tunnel in 2000.

The magnets will be cooled to a temperature of 456 degrees below zero so they can convey extremely high currents without any loss of energy, enabling them to control the path of the protons, which are 2,000 times heavier than the much more easily directed electrons that were used in the earlier accelerator.
