Physics set for monster revolution
2006 09 15


Physics could be turned on its head by a monster machine that can make black holes and may provide the first real evidence that extra dimensions exist.

Scientists have no idea what they will find when the Large Hadron Collider (LHC) starts smashing elementary particles together next year at energies never reached before.

One possibility is that it will create Higgs particles, which some theorists think may be involved in giving objects mass.

It might also verify Professor Stephen Hawking's theory that black holes "evaporate" over time, or produce mysterious "dark matter".

But physicists are most excited about the prospect of finding the "fingerprints" of other dimensions.

If that happened, it would lead to the biggest upheaval in physics since an apple bounced off Sir Isaac Newton's head and got him wondering about gravity.

Alternatives to the "Standard Model" that describes universe's particles and forces, such as String Theory, require more than the three familiar spatial dimensions of length, breadth and height. Some call for 11 or more dimensions, which may be tightly curled up and hidden from our world.

But these theories are founded on nothing but complex arithmetic. The LHC could provide the first solid evidence that one or more really do reflect the nature of reality.

Dr Brian Cox, from the University of Manchester, who will be working at the LHC in Geneva, said: "We've built a machine that operates beyond the energy where we really know what's happening. In the history of particle physics, there's never been such a jump. It could uncover some of the really big questions."

The circular-shaped LHC is the biggest machine ever built and cost in excess of £4.26 billion. Measuring 27km across, it sits 100m below the French-Swiss border. The machine has just one purpose, to collide beams of high energy protons and recreate conditions that existed less than a billionth of a second after the Big Bang at the dawn of creation.

End of Article.

Well I sure hope they know what they are doing. Messing with this type of stuff should almost be illegal.

As a side note, when I first read the name of the machine I thought it said Large Hardon collider. Changing the d and r around seems to make it a pretty funny name (Large Hard-on collider). I was laughing about that, was wondering where they came up with a name like this:LOL:B)

That is cool. Did anyone read "Angel's and Demon's"? I'm getting deja vu.

I heard somewhere that some physicists were worried that the LHC could do some serious, even apocalyptic damage. They're worried that it could create a runaway chain reaction that alters normal matter into "strange matter". Either that or it could create a mini black hole that could destroy the Earth and solar system. They even put it into a TV drama once.

I don't but it personally. I think it's just another Armageddon scenario to add to the list; and it's a long list! The universe could never have evolved into the form it exists in today if its structure was so vulnerable.

Despite Rumors, Black Hole Factory Will Not Destroy Earth
By Charles Q. Choi

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."
