Particle Collider Conducts Successful Test

Here is the article, in bold:

**GENEVA - The world’s largest particle collider successfully completed its first major test by firing a beam of protons around a 17-mile underground ring Wednesday in what scientists hope is the next great step to understanding the makeup of the universe. **

After a series of trial runs, two white dots flashed on a computer screen at 10:36 a.m. indicating that the protons had traveled the full length of the $3.8 billion Large Hadron Collider.

“There it is,” project leader Lyn Evans said when the beam completed its lap.

Champagne corks popped in labs as far away as Chicago, where contributing scientists watched the proceedings by satellite. Physicists around the world now have much greater power than ever before to smash the components of atoms together in attempts to see how they are made.

“Well done everybody,” said Robert Aymar, director-general of the European Organization for Nuclear Research, to cheers from the assembled scientists in the collider’s control room at the Swiss-French border.

The organization, known by its French acronym CERN, began firing the protons — a type of subatomic particle — around the tunnel in stages less than an hour earlier.

Now that the beam has been successfully tested in clockwise direction, CERN plans to send it counterclockwise. Eventually two beams will be fired in opposite directions with the aim of recreating conditions a split second after the big bang, which scientists theorize was the massive explosion that created the universe.

The start of the collider — described as the biggest physics experiment in history — comes over the objections of some skeptics who fear the collision of protons could eventually imperil the earth.

The skeptics theorized that a byproduct of the collisions could be micro black holes, subatomic versions of collapsed stars whose gravity is so strong they can suck in planets and other stars.
“It’s nonsense,” said James Gillies, chief spokesman for CERN, before Wednesday’s start.

CERN is backed by leading scientists like Britain’s Stephen Hawking in dismissing the fears and declaring the experiments to be absolutely safe.

Gillies told the AP that the most dangerous thing that could happen would be if a beam at full power were to go out of control, and that would only damage the accelerator itself and burrow into the rock around the tunnel.

Nothing of the sort occurred Wednesday, though accelerator is still probably a year away from full power.

“On Wednesday we start small,” said Gillies. “A really good result would be to have the other beam going around, too, because once you’ve got a beam around once in both directions you know that there is no show-stopper.”

The project organized by the 20 European member nations of CERN has attracted researchers from 80 nations. Some 1,200 are from the United States, an observer country which contributed US$531 million. Japan, another observer, also is a major contributor.

The collider is designed to push the proton beam close to the speed of light, whizzing 11,000 times a second around the tunnel.

Smaller colliders have been used for decades to study the makeup of the atom. Less than 100 years ago scientists thought protons and neutrons were the smallest components of an atom’s nucleus, but in stages since then experiments have shown they were made of still smaller quarks and gluons and that there were other forces and particles.

**The CERN experiments could reveal more about “dark matter,” antimatter and possibly hidden dimensions of space and time. It could also find evidence of the hypothetical particle — the Higgs boson — believed to give mass to all other particles, and thus to matter that makes up the universe. **
**Some scientists have been waiting for 20 years to use the LHC. **

I found it interesting and thought I’d share it.

The link is

I find it hard to understand why they always say “after the big bang” and not at the big bang. Maybe they should rename the theory “Post Big Bang Theory”.

Because the closer you get to the Big Bang, the more the laws of physics break down. As you travel backward, more and more of the universe hadn’t been created yet. There’s a point before which atoms did not exist. Then, before that, a point before quarks existed. Then, finally, you reach a point at which time breaks down and even it ceases to exist, and you fall into a paradox. How can you possibly study linear events when there is no time? When you hit that barrier, it’s like a wall that you can’t peer behind. No one will ever know what happened in the first billionths of a second of our universe, but we can get close. The closer you get, the more simple the universe was, and you can discover the most elementary laws that govern it. However, you can’t actually research the explosion itself.

It’s kinda like going faster than light. Since mass increases the faster you travel, you can never go faster than light, because at that speed mass becomes infinite. You can’t accelerate an infinite mass.

AT the big bang, the universe was essentially a singularity. It is like trying to “see” beyond the event horizon of a black hole. It can’t be done.

It’s still very interesting. I love Science! I wanted to be a physicist at one time but now am becoming an engineer. I love it. I really think it proves more that God exists when you really get involved in it rather than the opposite. Maybe that is my perception.

Well, physics needs some original thinkers. I just started reading “The Trouble With Physics” by Lee Smolin. The author laments that physics seems to have reached a semi-dead end over the past quarter century, and needs to make progress on 4 basic problems to advance further.

i don’t know, it seems to me they could be going to territory we weren’t meant to go to, but who am i to say?

i found it interesting that there were also 3 earthquakes - japan, indonesia and iran.

didn’t they just turn it on, but it hasn’t really been tested yet or hasn’t done the big job it is supposed to do?

On the side note the person who proposed the Big Bang theory was a Catholic priest name Georges Henri Joseph Éduard Lemaître (July 17, 1894 – June 20, 1966) honorary prelate, professor of physics and astronomer at the Université catholique de Louvain. He sometimes used the title Abbé or Monsignor.

He did not call it the Big Bang. He refer to the event as the “day without yesterday.”

From Wikipedia,

Lemaitre was a pioneer in applying Einstein’s theory of general relativity to cosmology. He suggested a precursor of Hubble’s law in 1927. In 1931, he published his primeval atom theory in Nature. At the time, Einstein believed in a static universe and had expressed skepticism about Lemaître’s 1927 paper. A similar solution to Einstein’s equations, implying a changing radius of the universe, had been proposed in 1922 by Alexander Friedman, as Einstein told Lemaître when he approached him with the theory at the 1927 Solvay Conference. (Einstein had also criticized Friedman’s theory.) But it is Lemaître’s theory that changed the course of science, for the following reasons:

Friedman was a mathematician who neither worked with astronomical data nor cared whether his theory was a description of physical reality.
Friedman died in 1925, soon after first proposing his theory.
Lemaître worked with astronomers and designed his theory to have testable implications, and to be in accord with observations of the time.
Arthur Eddington made sure that Lemaître got a hearing in the scientific community.
Lemaître proposed his theory at an opportune time, since Edwin Hubble would soon publish his velocity-distance relation that strongly supported an expanding universe and, consequently, the Big Bang theory. In fact, Lemaître’s 1927 paper derived what became known as Hubble’s Law, two years before Hubble did so. Because Lemaître spent his entire career in Europe, his contributions are not as well known in the United States (USA) as those of Hubble or Einstein, men well known in the USA by virtue of residing there.

Both Friedman and Lemaître concluded that the universe must be expanding. Lemaître further concluded that an initial “creation-like” event must have occurred. This is the Big Bang theory as we know it today, and why he is credited with its discovery.

Einstein at first dismissed Friedman and then (privately) Lemaître out of hand, saying that not all mathematics leads to correct theories. After Hubble’s discovery was published, Einstein quickly and publicly endorsed Lemaître’s theory, helping both the theory and its proposer get fast recognition.[4]

In 1933, Lemaître found an important inhomogeneous solution of Einstein’s field equations describing a spherical dust cloud, the Lemaitre-Tolman metric.

i am not sure my brain is able to put my thoughts around all of this.

a day without yesterday. i am not sure i want to know where this might lead.

Fr. Lemaître purposes that the universe had a beginning just as stated in the Book of Genesis.

He purposes the “Big Bang” theory.

maybe i missed something, but i thought that had already been determined.

or was it just speculation?

He also have another word for it. He called it his 'hypothesis of the primeval atom."

Well, according to the W-Map it may prove the existence of the Big Bang. All these are still just theories.

Wow, never knew it was a brother in the Faith. Awesome!

Just as an update, the Large Hadron Collider has malfunctioned and may not be working again until next year.

But the unique qualities of the world’s largest particle collider mean that the meltdown of a small electrical connection could delay its groundbreaking research until next year, scientists said Sunday.

Because the Large Hadron Collider operates at near absolute zero — colder than outer space — the damaged area must be warmed to a temperature where humans can work. That takes about a month. Then it has to be re-chilled for another month.

As a result, the equipment may not be running again before the planned shutdown of the equipment for the winter to reduce electricity costs. That means Friday’s meltdown could end up putting off high-energy collisions of particles — the machine’s ultimate objective — until 2009.;_ylt=ArYMuhVPtw1KFWfhEd.HEcsiANEA


Yes. you could see what it was like at the time of the big bang. or before it. cause time doesn’t excist. not then not now. time isa man made idea. and since man wasn’t around before the big bang. or a long period after it. so it means time wasn’t either. therefore things could excists before and after the big bang


Actually. you could. But you would need a particle collider the size of the solar system.
