A project to re-enact the "Big Bang" at CERN near Geneva on Wednesday is getting the rap treatment on the Internet from a group of young people working there.
"Twenty seven kilometres, a tunnel underground "Designed with a mind to send protons around "A circle that crosses through Switzerland and France "Sixty nations contribute to scientific advance," it runs.
The nearly five-minute video has been a big hit on YouTube (www.youtube.com) and some other sites (www.vimeo.com and www.teachertube.com), far more than the 23-year-old American would-be science writer who wrote the words ever expected.
Scientists at the world's largest particle collider have fired the first protons into a 17-mile-long tunnel in science's next great step to understand the makeup of the universe.
Project leader Lyn Evans gave the go-ahead to send the protons into the accelerator below the Swiss-French border early Wednesday.
The $3.8 billion Large Hadron Collider was under construction since 2003. Scientists hope it will provide the necessary power to smash the components of atoms so that they can see how they are made.
The startup has been eagerly awaited by 9,000 physicists around the world who will conduct experiments here.
Some skeptics have said they fear the collisions of protons could eventually imperil Earth.
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 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 deep below the Swiss-French border.
And full power is probably a year away.
A good result for Wednesday would be to have one beam going all the way around the tunnel in a counterclockwise direction. If that works, the scientists will then try to send a beam in the other direction.
''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,'' Gillies said. ''It's going to work.''
However, if there is some blockage in the machine, experts will have to go in and fix the problem, and that could take time.
The LHC, as the collider is known, will take scientists to within a split second of a laboratory recreation of the big bang, which they theorize was the massive explosion that created the universe.
The project organized by the 20 European member nations of CERN has attracted researchers of 80 nationalities. Some 1,200 are from the United States, an observer country which contributed $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. But even their younger colleagues are excited that startup has finally arrived.
''I think it's a very important project,'' said Katie McAlpine, 23, a Michigan State University graduate who made a rap video about the project.
''It's mostly out of scientific curiosity, what is the universe made of? How does it work? What are the rules? That's very exciting and it's important to advance our knowledge,'' she told Associated Press Television News.
She said she was surprised by the success of the video, which has had more than a million views on YouTube and which has received approval from CERN for its scientific accuracy, especially in its success with young people.
