Work begins on world's deepest underground lab
By DIRK LAMMERS, Associated Press Writer Dirk Lammers, Associated Press Writer – 1 hr 17 mins ago
AP – Dignitaries and board members applaud South Dakota Gov. Mike Rounds, at the podium, during dedication SIOUX FALLS, S.D. – Far below the Black Hills of South Dakota, crews are building the world's deepest underground science lab at a depth equivalent to more than six Empire State buildings — a place uniquely suited to scientists' quest for mysterious particles known as dark matter. Scientists, politicians and other officials gathered Monday for a groundbreaking of sorts at a lab 4,850 foot below the surface of an old gold mine that was once the site of Nobel Prize-winning physics research. The site is ideal for experiments because its location is largely shielded from cosmic rays that could interfere with efforts to prove the existence of dark matter, which is thought to make up nearly a quarter of the mass of the universe. The deepest reaches of the mine plunge to 8,000 feet below the surface. Some early geology and hydrology experiments are already under way at 4,850 feet. Researchers also hope to build two deeper labs that are still awaiting funding from Congress. "The fact that we're going to be in the Davis Cavern just tickles us pink," said Tom Shutt of Case Western Reserve University in Cleveland, referring to a portion of the mine named after scientist Ray Davis Jr., who used it in the 1960s to demonstrate the existence of particles called solar neutrinos. Davis and a colleague named John Bahcall won a share of the 2002 Nobel Prize for physics for their work. The old Homestake Gold Mine in a community called Lead (pronounced LEED) was shut down in 2001 after 125 years. Pumps that kept the mine dry were turned off years ago, so workers have been drying it out to prepare for the new research. Before the labs are built, crews must also stabilize the tunnels and install new infrastructure. The lab at 4,850 feet is not much to look at yet. A rusty orange film covers the walls, floors, ceilings and debris left behind by miners. The first dark matter experiment will be the Large Underground Xenon detector experiment — or LUX — a project to detect weakly interacting particles that could give scientists greater insight into the Big Bang explosion believed to have formed the universe. Shutt, along with Brown University's Rick Gaitskell and nearly a dozen collaborators will work at the site to search for dark matter, which does not emit detectable light or radiation. But scientists say its presence can be inferred from gravitational effects on visible matter. Scientists believe most of the dark matter in the universe contains no atoms and does not interact with ordinary matter through electromagnetic forces. They are trying to discover exactly what it is, how much exists and what effect it may have on the future of the universe. Physicists have said that without dark matter, galaxies might never have formed. By learning more about dark matter, they hope to understand better whether the universe is expanding or contracting. The research team will try to catch the ghostly particles in a 300-kilogram tank of liquid xenon, a cold substance that is three times heavier than water. If they tried to detect dark matter above ground, the highly sensitive detector would be bombarded by cosmic radiation. Scientists hope to start construction on the two deepest labs by 2012 and open them by 2016. The projects are expected to cost $550 million. http://news.yahoo.com/s/ap/20090622/...ground_science Last edited by Dantheman62; 06-23-2009 at 12:47 AM. |

OK, everything must be alright... the scientists say so! A great way to get $550 million though. Last edited by Anchor; 06-23-2009 at 03:51 AM. Reason: dead text removal |

Re: Work begins on world's deepest underground lab
Congratulations to all of the scientists who will eventually be working miles underground within their lab deep within the bowels of the earth. May they find what they seek deep in the dark.
You know..this reminds me of the movie Resident Evil and the Umbrella Corporation that built an underground city/research facility miles below a train station I think it was. A nasty virus ends up escaping and turning folks into zombies. Maybe we'll have dark matter zombies walking about. |

Re: Work begins on world's deepest underground lab
Kinda creepy, but I can't help but continue correlating anything to do with underground city's, labs, and bunkers with slimy skinned humans with big eyes from the future, greys, and earthworm skinned zombies being portrayed or pics drawn and displayed.
Seems like the message is not to go underground. Maybe... no sunlight means no DNA maturation- no lightbulb in the oven to cook it properly (now that's dark)! Last edited by Christo888; 06-23-2009 at 02:28 AM. |
