“Why, typically I’ve believed as many as six unattainable issues earlier than breakfast.” ― Lewis Carroll, Alice in Wonderland

I have been to see ALICE — although there was no wanting glass to leap by way of, only a retina scanner and one very lengthy elevator journey down into the earth. I’ve toured a CMS that has nothing to do with on-line publishing. I’ve even gently laid my physique on probably the most highly effective particle accelerator on the planet and raised the ire of surrounding engineers within the curiosity of a superb shot. I did all of this at CERN, the worldwide particle physics laboratory situated close to Geneva, Switzerland. However you in all probability comprehend it greatest because the birthplace of the world broad net and residential of the Giant Hadron Collider. And, sure, it was all precisely like a strolling fever dream.

It is apt that a Lewis Carroll quote would encapsulate my two-day go to to CERN in June, a visit that occurred within the simmering Swiss warmth (enjoyable reality: A/C doesn’t exist anyplace on the sprawling campus). And the power, with a detector named after Carroll’s ever-curious protagonist Alice, brazenly invitations that connection. It isn’t exhausting to think about most of CERN’s resident physicists beginning their days with a robust cup of (scrumptious, European) espresso, a bowl of müesli and a superb pondering of the inconceivable. Perhaps “ponder” is the mistaken verb to use right here, contemplating one such scientist outright dismissed the notion of “impossibility” in dialogue with a fellow journalist. He even appeared to harbor an lively distaste for it. And he rightly ought to. In any case, particle physicists and the entire of CERN commerce in “marvel.” It is very almost a requirement for entry to the grounds.

The opposite important ingredient for entry to CERN’s labs is a dormant LHC. I discovered myself sporting exhausting hats and gazing on the surrounding Jura and Alps mountain ranges whereas shuttling from one underground cavern to the subsequent due to scheduled LHC upkeep. This era of inactivity has a twin objective for CERN’s engineers: it is partially a daily tune-up, however there’s additionally main restore work underway.

A superb portion of this two-yr downtime’s being devoted to correcting injury from a 2008 explosion that wrecked most of the LHC’s tremendous-conducting magnets. Although CERN’s engineers managed to get it again up and operating within the time since that incident, the LHC’s by no means fairly been the identical. It is truly been operating at simply half energy — nonetheless ok for main scientific breakthroughs just like the Higgs boson, however actually a shell of what it is meant to do. Come 2015 when the LHC is as soon as once more operable, it’s going to be the primary time the system collides its twin proton beams at an power of seven TeV (or teraelectron volts) every. To borrow CERN’s personal analogy, that is roughly equal to a automotive racing alongside at 994mph (or 1,600km/h).

Overlook the LHC for a second. The 2 detectors CERN made accessible — CMS and ALICE — are the actual sleeping technological beauties.

An beneath restore accelerator can also be a protected accelerator: there isn’t any leaking helium to displace the air, no lingering radiation to make issues toxic and no close to-absolute zero temperature of -456.three°F (mandatory for operation of the magnets) to make frostbite appear inviting. That confluence of hospitable elements is primarily why CERN allowed us to stroll a portion of the 17-mile (27km) lengthy tunnel that types a hoop beneath the Franco-Swiss border, alongside which 4 collision detectors are positioned. However overlook the LHC for a second, it is only a lengthy and unexciting pipe.

The 2 detectors CERN made accessible on this journey — CMS (Compact Muon Solenoid) and ALICE (A Giant Ion Collider Experiment) — are the actual sleeping technological beauties. It is these large rings of densely packed tremendous-conducting magnets, monitoring units and calorimeters that really put the seek for the Higgs boson into perspective. A particle so infinitesimally small, so elusive, so utterly integral to our understanding of physics that it requires a sixty nine x 50 x 50 ft tall (21 x 15 x 15m), 12,500-ton detector with a solenoid magnet at its coronary heart to generate an electromagnetic subject roughly one hundred,000 occasions stronger than the Earth’s personal simply to seek out it.

CERN is massive-price range science and it appears identical to the films.

In fact, seeing is believing. Which is why we’re extending that golden ticket to you within the type of a mini-doc and curated photograph galleries. CERN, as you will see, is massive-price range science and it seems identical to the films: large machines in subterranean chambers, a multitude of cables and sufficient warning indicators to let you already know nice issues are occurring. In the event you’re in search of solutions to the recognized mysteries of our universe or a deeper dive into the hows and whys of the LHC, you will not discover them right here. This can be a digital tour; it is the subsequent, neatest thing to truly being there. For all that headier stuff, you possibly can keep tuned for our upcoming Primed.
