Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

It's just another day of digital carnage in the Hadron Collider, the world's largest and highest-energy particle accelerator.

Two billion head-on express-train-style collisions occur every second around the clock on the underground 27km circuit (which is the same length as the Circle Line on the London Underground). There are no casualties because these "trains" are very small – only 1.68 femtometres in diameter. But their impact is global. Last July, a Higgs Boson particle was seen escaping one of the crashes, carrying the answer to why we exist. The euphoria has now cooled but the tracking of the link between the mind-boggling hugeness and fantastical minuteness of the universe, goes on: strange quarks, smart quarks, muons and gluons, flashed on screens around the site, like racing results, even in the canteen where scientists, visitors and students circulate with lunch-laden trays, mimicking the 94 per cent of circulating hadrons that do not collide. Of the ones that do, only a tiny fraction can break the supersymmetry and generate Higgs. But "improbable" is not "impossible" in this wonderland of whizzing particles.

ALICE (A Large Ion Collider Experiment), one of the four stations of CERN, will soon recreate quark-gluon plasma, the original life-blood of the universe, and from next month, when the system shuts down briefly for refurbishment, visitors can go down the rabbit-hole and explore the tunnel where the magic happens. "What if", someone asks, " lets you down and all your theories are proved wrong?" An Italian Professor of Particle Physics beams: "Then we know nothing! The field is wide open! And that for a scientist is the best outcome."
