  • Pour one out for the Tevatron particle accelerator, because it's shutting down today

    The eyes of the physics community are collectively fixed upon Illinois today, where, later this afternoon, researchers at Fermilab will shut down the Tevatron particle accelerator... for good. That's right -- the world's second-largest collider is being laid to rest, after a remarkable 25-year run that was recently halted due to budgetary constraints. Earlier this year, Fermilab's scientists and a group of prominent physicists pleaded with the government to keep the Tevatron running until 2014, but the Energy Department ultimately determined that the lab's $100 million price tag was too steep, effectively driving a nail through the accelerator's subterranean, four-mile-long coffin. First activated in 1985, the Tevatron scored a series of subatomic breakthroughs over the course of its lifespan, including, most notably, the discovery of the so-called top quark in 1995. Its groundbreaking technology, meanwhile, helped pave the way for CERN's Large Hadron Collider, which will now pursue the one jewel missing from the Tevatron's resume -- the Higgs boson. Many experts contend that the collider could've gone on to achieve much more, but its ride will nonetheless come to an inglorious end at 2PM today, when Fermilab director Pier Oddone oversees the Tevatron's last rites. "That will be it," physicist Gregorio Bernardi told the Washington Post. "Then we'll have a big party."

  • Antimatter gets trapped for 15 minutes by CERN scientists, escapes unharmed

    Antimatter particles are elusive little critters that tend to disappear moments after being spotted. Unless, it turns out, you trap them in a "magnetic bottle" and turn the temperature right down to almost absolute zero. CERN scientists have now used this technique to hold 300 antihydrogen particles for up to 1,000 seconds, relaxing them into their ground (stationary) state to make them easier to study. This opens the way for further research later in the year, when captured particles will be prodded with lasers and microwaves to see if they obey the same laws of physics that govern everything else in our universe. After all this effort, we're quietly hoping they don't. [Thanks, Howard]

  • Astronomers snap black hole murder in graphic detail (video)

    We tend to imagine a black hole sucking everything around it straight into oblivion. The truth, however, is even more gruesome. Astronomers have just captured an ultra hi-res image of our neighbouring galaxy, Centaurus A, and it helps to reveal what actually happens. Matter is yanked helplessly towards a black hole at the galaxy's core, but it refuses to die quietly. For some unknown reason, it erupts as it falls, spewing out vast plumes of particles -- like blood from celestial murder. These death throes emit radio waves, allowing us to witness them using radio telescopes even though we are 12 million light-years away. If only we were closer; if only we could intervene. Alas, all we can do is watch the video after the break and hit the source links for a fuller explanation -- though, admittedly, none of those sound like awful options.

  • Has the Higgs Boson been discovered by LHC rival? Are we still here? (Update: No Higgs discovery, and we're still here)

    The Large Hadron Collider isn't the only bad boy on the block looking for the so-called God particle -- technically known as the Higgs Boson. A lesser known facility, the Tevatron -- located at the Fermi National Accelerator Laboratory in Batavia, Illinois -- has also been furiously searching for the particle which would help to explain the origins of mass in the universe -- and it looks like they might have found it. A rumor has been swirling about recently that the found particle is a "three-sigma," meaning that it's got a 99.7 percent statistical likelihood of being correct -- but the lab itself has yet to confirm or deny. The Tevatron, which was completed 27 years ago, is the second largest accelerator in the world (after the LHC) and it's expected to be retired once the CERN facility is fully operational. Update: Well, that was fun for the few hours that it lasted. New Scientist has published a piece confirming that Tevatron is in fact denying the rumor, and no Higgs Boson discovery has gone down.

  • LHC breaks its own energy record, still less powerful than Lady Gaga

    The Large Hadron Collider is no stranger to setting energy records: back at the end of November it broke the 0.98 TeV record by hitting the 1.18 TeV mark. Well, the problem beleaguered collider's just handily surpassed itself -- this time with a truly stunning 3.5 TeV -- with beams of protons on record as having circulated at 3.5 trillion electron volt. Now, we're not scientists or anything, but that sure is a lot of volts! CERN's moving on later this week and will begin colliding the beams so they can check out the tiniest particles within atoms in the hopes of finding out more about how matter's made up. We look forward to hearing all about that, too -- but until then, we made do by reading the source over and over.

  • Large Hadron restart delayed again -- you can relax until October

    If you were enjoying these warmer months, taking time away from terrestrial black hole spotting due to the continued deactivation of CERN's Large Hadron Collider, feel free to extend those summer vacation plans a little bit. The particle crasher and supposed non-threat to life as we know it was previously set to restart in September after some damage put it on the inactive list many moons ago. Now CERN's Head of Communications, James Gillies, is saying that the restart is likely to be smashed back a few more weeks into October, meaning New Englanders might just get in one more leaf peeping season before all we know is mashed into an incomprehensibly small ball of matter from which nothing can escape -- not even Gundam robots.

  • Scientists get death threats over Large Hadron Collider

    Really people, enough is enough. Death threats? Seriously? According to a fresh report from the Telegraph, gurus working on the mysterious Large Hadron Collider are receiving all sorts of strange messages, e-mails and faxes as the go-live date (this Wednesday, supposedly) draws ever closer. For those curious about why some folks are up in arms over this thing, we'll simply point you to this very informational rap video; for those opposed to nerdy hip-hop, let's just say its primary goal is to "seek out new particles including the long-awaited Higgs boson responsible for making things weigh what they do and the possible source of gravity called dark matter." Somehow or another, the paranoid among us think that carrying out those tasks will rip the world wide open or leave you stuck in 1990 with nothing in your CD player but Ice Ice Baby. Okay, so maybe that last scenario is worth getting worked up about.[Via TGDaily]
