Gravitational waves are our window into the early universe

"We have detected gravitational waves. We did it," David Reitze, executive director of the Laser Interferometer Gravitational-Wave Observatory (LIGO), said at a press conference in Washington on Thursday. Reitze has good reason to be excited. LIGO's...

The Large Hadron Collider’s next upgrade is moving forward

The Large Hadron Collider recently got back to work after a two-year layoff for maintenance and upgrades, but soon it will go under the knife again. Last week 230 scientists met at CERN in Switzerland to discuss the High-Luminosity LHC (HL-LHC) pro...

Google Street View lets you stroll around CERN, no doctorate required

Street View now lets you stroll around CERN, no physics doctorate required

Previously, free rein to explore the labyrinthine laboratory that is CERN has been granted only to the lucky, or those with four degrees and an aptitude for finding theoretical particles. That changes today, however, as anyone can now explore the home of the Large Hadron Collider in Geneva, Switzerland through Google Street View. All the imagery was captured back in 2011, but it's finally been stitched together, allowing you to wander freely around the site of the famous particle accelerator and learn a little about its experiments. Hit up Google Views to begin your personal guided tour, and let us know if you spot this Higgs fellow everyone's so keen on finding.

Primed: The smashing science behind particle accelerators

Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com.

The smashing science behind particle accelerators

Long before the Large Hadron Collider (LHC) could smash its first atoms, researchers manning the Tevatron collider at Fermilab, in a quiet suburb 40 miles west of Chicago, raced to find evidence that the Higgs boson exists. After roughly three decades of service, the Tevatron shut down for good in late 2011, dealing the city of Batavia's largest employer a significant blow. Less than 18 months later, the LHC (the Tevatron's technological successor) also went offline - albeit temporarily. Only four years after recording its first proton collisions, the team at CERN is already scrambling to upgrade the staggering LHC, which lies under parts of no less than five cities in both France and Switzerland. With the world's largest particle colliders smashing a whole lot of nothing together for the next two years at least, the field of high-energy physics research is starting to look resource-starved. Of course, many might ask why exactly we need giant atom smashers like this, or even how they work. It turns out that first part is quite a bit easier to answer than the second.

During the last several decades, particle accelerators have revealed the existence of elementary particles such as quarks, led to the discovery of antimatter and generally helped us unlock the mysteries of the universe. And once they were done splitting atoms and probing the darkest corners of theoretical physics, accelerators often led to breakthroughs in medical imaging and cancer research. So, as massive colliders seem ready to land on the endangered species list, it seems as good a time as any to explain what a particle collider is, how it works and what we as a society have to gain from the research.

Into the heart of CERN: an underground tour of the Large Hadron Collider (video)

DNP

"Why, sometimes I've believed as many as six impossible things before breakfast."
― Lewis Carroll, Alice in Wonderland

I've been to see ALICE -- though there was no looking glass to jump through, just a retina scanner and one very long elevator ride down into the earth. I've toured a CMS that has nothing to do with online publishing. I've even gently laid my body on the most powerful particle accelerator in the world and raised the ire of surrounding engineers in the interest of a good shot. I did all of this at CERN, the international particle physics laboratory located near Geneva, Switzerland. But you probably know it best as the birthplace of the world wide web and home of the Large Hadron Collider. And, yes, it was all exactly like a walking fever dream.

Visualized: this is where the Higgs Boson was discovered

Visualized this is where the Higgs Boson was discovered

It's not everyday you get to tour CERN, the international particle physics research facility that spans the border of both France and Switzerland. It's even more rare to go down into the sprawling facility's tunnels to see an inactive and under repair Large Hadron Collider -- currently, the world's most powerful particle accelerator. But that's just what we did this past week, as we spent some quality time with CERN's physicists and visited the dormant LHC, as well as two of its detectors: ALICE and CMS (pictured above). There'll be much more to come from our trip to CERN, so stay tuned. But for now feast your eyes on the birthplace of the Higgs Boson discovery.

CERN release preliminary results: particle looking ‘more and more like a Higgs boson’

CERN's latest update to its elementary particle project is that the new particle that it was able to pick up is behaving "more and more like a Higgs boson." The team isn't being particularly specific here, as its not certain just yet whether it's detected a 'standard model' particle or the lightest of several possible bosons predicted in other spin-off theories. Researchers are referencing the interactions of the particle (particularly its spin, or lack off) as the main reason why they reckon they're dealing with a genuine Higgs boson and work will now focus on exactly what kind of boson they've managed to snag.

Higgs Boson update: it’s cool, it exists, it’s not necessarily so ‘exotic’

Higgs Boson update being the God particle doesn't necessarily make you interesting

As a prominent musician once noted: all that hype doesn't feel the same next year, boy. And that's sadly proving true for our old friend Higgs Boson, who shot to fame last Summer but is now waking up to find only a handful of fans camped outside his collider. Part of the problem is simply that things have become procedural and academic -- CERN scientists met in Italy this week to share their latest findings, but the updates were mostly either inconclusive or suggestive of a rather mundane-seeming subatomic entity.

At the time of Higgs' discovery, observers were especially interested in the possibility that this mysterious particle didn't decay in exactly the way science had predicted. It seemed to break down into an excess of photons, such that it might potentially reveal something unexpected about dark matter and the structure of space-time. But as data continues to be gathered, it appears more likely that the extra photons may have been a statistical anomaly, leading one researcher to admit on Twitter that his ATLAS team is "not too excited" about it anymore. Nothing is confirmed at this point, however, and other scientists have since tweeted to caution against jumping to conclusions. At least we can say for sure that Higgs still exists. And if the poor thing can't hold the universe together and mess with the laws of physics at the same time, then so be it.
