A major upgrade to the Large Hadron Collider is underway
The Large Hadron Collider (LHC) is getting an upgrade that will let researchers collect approximately 10 times more data than they can now. Currently, the particle accelerator can produce up to one billion proton-proton collisions, but that number will be increased significantly once the upgrades are in place. Today, a ground-breaking ceremony kicked off the work that's scheduled to be wrapped up by 2026.
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 find is a huge, Nobel Prize-worthy accomplishment on par with CERN's discovery of the Higgs particle in 2012. Just as Higgs particles revolutionized the standard model of physics, gravitational waves are set to do the same to Einstein's theory of general relativity. Simply put, it will fundamentally alter how we view and interact with the universe around us.
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) project, and move it from the development phase to the construction stage. After two more Long Shutdown periods in 2019 and 2024, the HL-LHC will deliver 10 times the amount of particle collisions it does now. New technology coming its way includes 12 superconducting quadropole magnets (one is pictured above), "crab" cavities that tilt the particle beams before collisions and more. When we took a look at the science behind particle accelerators a few years ago, the HL-LHC was already in development and after a four year design study it's one (big) step closer to reality.

The Higgs boson could destroy the universe in the wrong conditions
That Higgs boson that everyone was so eager to find last year? As it turns out, it could be the end of everything -- in the wrong circumstances, anyway. In his upcoming book Starmus, Stephen Hawking notes that the once-elusive particle could become less than perfectly stable at energy levels of 100 billion giga-electronvolts or higher. If it gets to that state, it could trigger a vacuum bubble that would expand at the speed of light, eventually collapsing all space and time; you wouldn't even know the disaster was coming if the event happened on Earth.
The biggest stories of 2013: Console wars, Bitcoin's boom and the NSA's very bad year
2013 was a bust! Or so we've been told. Whether you follow that line of thinking or reflect on the last 363 days in a more optimistic light, it's clear the year wasn't all big breakthroughs and great triumphs. This was the year of government surveillance revelations, fallen giants and lackluster product releases. But it was also the year Netflix took on the studios, patent reform became a real priority in DC and two new game consoles hit the scene. No, we won't be riding our hoverboards into the sunset at the close of 2013, but the stories that rocked the industry had a profound impact not only on technology, but also on society as a whole. So let's raise those half-empty glasses and make a toast as we recap the year that was: Here's to the glassholes!
Higgs boson researchers awarded Nobel Prize for physics
Sure, it may have been one of the easier Nobel prizes to call in recent years -- at least partly -- but that doesn't make it any less notable. This morning, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics to Peter Higgs and Francois Englert "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles," or what's come to be known as the Higgs boson. While the prize doesn't extend to the researchers at CERN who confirmed the existence of the Higgs particle last year, the Nobel committee did cite their work in the announcement, as did Peter Higgs himself, who said in a prepared statement that he "would also like to congratulate all those who have contributed to the discovery of this new particle." Professor Higgs isn't offering any more than that statement today, though -- one of his Edinburgh University colleagues tells the BBC that "he's gone on holiday without a phone."
Google Street View lets you stroll around CERN, no 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. 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)
"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. %Gallery-192868% %Gallery-192867% %Gallery-192869% %Gallery-192870%
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 states 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'
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.
Alt-week 8.4.12: buckyballs, bosons and bodily fluids
Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days. Remember when we told you last week that we live in a strange world? Well, we had no idea what we were talking about. Seriously, things are about to get a whole lot weirder. High school is certainly a head-scratcher, no matter how old you are, but the mathematics of social hierarchies can't hold a candle to the mysteries of the buckyball. And, if the strange behavior of the familiar carbon molecule isn't enough for you, we've got an entirely new molecule to contend with, while the once-elusive Higgs Boson is getting us closer to unlocking the secrets of the universe. It's all pretty heady stuff, which is why we're also gonna take a quick detour to the world of human waste. This is alt-week.
CERN confirms existence of new particle consistent with Higgs boson (video)
Physics' big announcement had more in common with a leaky product launch than the serious business of re-writing the science books. But slack asset management aside, it's official: a new boson has been observed with a standard deviation of 5 (confidence of 99.9%). The highly anticipated announcement came this morning direct from CERN's press conference (via ICHEP in Melbourne,) and is the result of an intense, ongoing search for the elusive particle. The observation is of a boson particle with a mass of 125.3 ± 0.6 GeV, at a significance of 4.9 sigma. Joe Incandela -- giving the presentation -- said that this is "In agreement with the standard model at 95% confidence range." The boson is the heaviest ever found, and although this is still a preliminary result, it's by far the strongest case yet for the existence of the elusive Higgs. The sought-after particle is essential for supporting the current understanding of sub-atomic world, and its bearing on nuclear, and electromagnetic interactions. The next stage will be to determine the exact characteristics of the new particle and whether it matches the expectations of the Higgs, or is it in fact something more "exotic." This part will take much more time, but for now, a (very) small, but important piece of the puzzle has been found. Update: We're sure you've got many questions, and CERN apparently anticipated this.

CERN update on its search for Higgs boson starts at 3AM ET (video)
The cat would appear to be out of the bag, but if you must find out about the status of the Higgs boson search ASAP, check the video stream (embedded after the break) as CERN scientists reveal whatever it is they've found. The webcast is scheduled to kick off at 2:55AM ET, as a prelude to this year's ICHEP particle physics conference in Melbourne. Whenever the announcement comes we'll be sure to let you know, check the links below for more information. Update: So yeah, they've found a new particle "consistent with Higgs boson," check out all the details here.
Higgs boson just may, possibly, more or less be proven to exist by ATLAS and CMS teams
We had a false alarm over the possible discovery of the theory-unifying Higgs boson last year, but a bit of poking and prodding in subsequent months may well have given us much more definitive evidence of the elusive particle. According to some rare rumors emerging from Nature, both CERN's ATLAS and CMS detectors have seen particle decay signals suggesting the existence of Higgs to within a 4.5 to 5 sigma level of proof -- in other words, very nearly concrete evidence. That's not quite the 5-plus needed to settle the matter, but it's to a much higher level of certainty than before. As if to add fuel to the fire, ScienceNews even located a briefly posted, CERN-made video (sadly, since pulled) saying bluntly that the CMS team had "observed a new particle." Whether or not there's any substance is another matter. Nature hears that scientists are supposedly still working out what to say at an event on Wednesday, while CERN has made the slightly odd claim to ScienceNews that the yanked video is just one of several pre-recorded segments made to cover possible outcomes -- you know, in that "Dewey defeats Truman" sort of way. Unless the scientists have to go back to the drawing board, though, the focus from now on may be more on learning how Higgs behaves than its very existence. Any significant truth could see researchers proving the validity of the standard model of physics just as we're firing up our Independence Day barbecues.
CERN crew takes to Google+ for live Hangout
Got questions for CERN crew? We know we do. For instance, if a Higgs boson falls in the woods and no one is around to hear it, does it still create a miniature black hole that swallows the Earth and destroys us all? Well if you've got queries for the folks working the LHC, attempting to unlock the secrets of the universe then hit up the source link for a live Hangout at that most nerdy of social networks Google+. The conversation starts at 1 pm eastern time.
