The Standard Model is so correct it is disappointing
Beneath the Franco-Swiss border, the world's most powerful particle accelerator has gone quiet — not in defeat, but in preparation. The Large Hadron Collider, which gave humanity the Higgs boson and confirmed the elegance of its own theoretical foundations, enters a four-year, $1.5 billion transformation this July, hoping that more collisions will yield what more energy could not: a crack in the Standard Model, a glimpse of the 95 percent of the universe that remains invisible to science. Yet the deeper question stirring among physicists is not merely what the upgraded machine might find, but whether civilization will summon the will and resources to build something even larger — a $19 billion successor whose promise is measured not in revolutions, but in decimal places.
- The LHC's greatest achievement — confirming the Standard Model with extraordinary precision — has become its most unsettling result, leaving physicists without the anomalies they were hoping to chase.
- Dark matter, dark energy, and supersymmetry remain stubbornly absent from the data, and the universe's missing 95 percent continues to elude every instrument humanity has built.
- A fivefold increase in collision rates is the collider's best remaining bet, a strategy of sheer statistical pressure where raw power has so far failed to produce surprise.
- The proposed Future Circular Collider — 91 kilometres of tunnel and nearly $19 billion in cost — faces pointed skepticism that it would refine known measurements rather than open genuinely new scientific territory.
- In an era of strained budgets and competing global crises, the fate of the next great machine may hinge less on physics than on whether governments can still believe in the value of questions without guaranteed answers.
The Large Hadron Collider goes dark this July. After more than a decade of splitting protons at near light-speed in a 27-kilometre tunnel beneath the Franco-Swiss border, the machine will fall silent for four years while engineers spend roughly $1.5 billion transforming it into the High Luminosity LHC — a collider designed not to hit harder, but to hit far more often. When it returns in 2030, it will produce collisions at five times the current rate, and ten times the total over its lifetime.
The upgrade arrives at a peculiar moment in physics. The LHC's signature achievement — the 2012 discovery of the Higgs boson, theorized since 1964 — was a triumph that also closed a chapter. Since then, the machine has found dozens of exotic hadrons and briefly recreated the quark-gluon plasma of the early universe, but it has found almost nothing that contradicts the Standard Model, the decades-old theoretical framework physicists had quietly hoped to break. As CERN physicist Archana Sharma observed, the Standard Model's stubborn correctness is both a vindication and a disappointment.
The hope now is that sheer volume will succeed where energy alone could not. More collisions mean better odds of detecting dark matter or dark energy — the invisible constituents of 95 percent of the universe — or finding evidence of supersymmetry, which predicts a heavier twin for every known particle. But the conversation at CERN has already moved further ahead.
In May 2026, the CERN Council endorsed plans for a Future Circular Collider: a 91-kilometre machine colliding electrons and positrons, with a price tag approaching $19 billion and a decision expected around 2028. A later proton-colliding phase might follow in the 2070s. Critics, including physicist Sabine Hossenfelder, argue that the first phase would largely refine measurements already made, adding decimal places rather than opening new frontiers. The scientific case is genuinely contested.
What may ultimately decide the matter is not physics but politics and will. Sharma, among the first Indian scientists CERN employed, notes that every expenditure at the laboratory sparks fierce debate, even as researchers from fifteen nations — including longstanding Indian and Pakistani colleagues — work side by side. Her hope is that India enters the next machine at the design stage rather than arriving late to construction. The collider that goes dark this month will return, upgraded and searching. Whether anything larger follows depends on questions that no particle detector can resolve.
The Large Hadron Collider is going dark this month. After more than a decade of smashing protons together at nearly the speed of light, the machine that sits in a 27-kilometre tunnel beneath the Franco-Swiss border will fall silent in July, its beams switched off for the first time since 2009. The shutdown will last four years. The bill will run to roughly $1.5 billion. When the collider wakes again in June 2030, it will be transformed into what physicists call the High Luminosity LHC — a machine designed to collide particles not harder, but far more often.
At CERN, the European research laboratory that operates the collider, the summer heat bears down on grey concrete buildings that give no sign of the extraordinary machinery buried beneath them. In the control rooms, physicists watch banks of monitors displaying the coloured traces left behind by each collision — a visual language of particle decay that reads like an electrocardiogram of the universe itself. One detector, called ALICE, sits deep underground, its purpose to catch glimpses of matter that has not existed since the first microseconds after the Big Bang. The hope, always, is that somewhere in the wreckage of a collision will be something unexpected. Something that breaks the rules. Something new.
For more than a decade, the LHC has been extraordinarily good at confirming what physicists already knew. In 2012, it found the Higgs boson, the particle that had been theorized since 1964 and whose discovery earned Peter Higgs and François Englert the Nobel Prize. Since then, the machine has discovered roughly eighty new hadrons — composite particles made of quarks — including exotic varieties with four or five quarks instead of the usual two or three. It has briefly recreated the quark-gluon plasma, the roiling soup of unbound particles that filled the universe in its infancy. It has tightened the boundaries of where undiscovered particles cannot be hiding. It has done all of this with remarkable precision. And yet, it has found almost nothing that contradicts the Standard Model, the textbook of particle physics that has stood for decades.
This is, paradoxically, both a triumph and a disappointment. Archana Sharma, a physicist at CERN and among the first Indians the laboratory employed, put it plainly: "It is also, alas, disappointing, that the Standard Model is so correct." The collider was built partly in hope of finding cracks in that model, hints of physics beyond it. Instead, it has mostly confirmed what was already written. The upgrade is meant to change that calculus. By increasing the collision rate roughly fivefold, and the total number of collisions tenfold over the machine's lifetime, physicists hope to improve their odds of spotting dark matter or dark energy — the invisible substances that make up 95 percent of the universe and remain almost entirely mysterious. They hope for evidence of supersymmetry, a theory proposing that every known particle has a heavier, undiscovered twin. They hope for something, anything, that the Standard Model does not explain.
But the question facing CERN now extends beyond the upgrade itself. The laboratory is already planning for what comes next. In May 2026, the CERN Council endorsed the Future Circular Collider, a proposed machine that would operate in a 91-kilometre tunnel and collide electrons and positrons rather than protons. The price tag is nearly $19 billion. A decision on whether to build it is expected around 2028. A later phase might involve a 100-teraelectronvolt proton machine, perhaps in the 2070s. This is where the conversation becomes harder.
Not all physicists are convinced that a larger collider is worth the cost. The first phase of the Future Circular Collider would operate at lower energies than the LHC reaches today, designed for precision rather than raw power. Critics, including physicist Sabine Hossenfelder, have argued that such a machine would mostly refine measurements of quantities already known, pinning down numbers to a few more decimal places rather than discovering anything genuinely new. The real question, though, may not be scientific at all. It is whether the world's governments and institutions will commit $19 billion to a machine whose promise is incremental improvement rather than revolutionary discovery. It is whether, in an age of war and strained budgets, such ambition can survive.
At CERN, Sharma notes that consensus comes hard. "For every penny there is a huge discussion," she says. Yet the laboratory has held fifteen nationalities at once — Indian and Pakistani scientists working alongside Chinese and European colleagues. India has been part of CERN since the 1960s. Her wish is that Indian industry join not at the construction stage, but at the design stage, so that the country does not miss the opportunity entirely. The collider that goes dark this July will return in 2030, upgraded and hungry for new physics. Whether anything larger will ever be built depends on questions that no amount of data can answer.

We were very lucky with the Higgs boson, that within the first few years of operation we found it. Now, perhaps dark matter is around the corner, and we need more data, and this is exactly why we are upgrading the LHC.— Archana Sharma, CERN physicist

La Conversación del Hearth Otra perspectiva de la historia
So the LHC is shutting down for four years. That sounds like a long time to wait for answers.
It is, but the upgrade is necessary. Right now the machine collides particles at high energy, but not very often. The upgrade increases the collision rate roughly fivefold. More collisions means better odds of seeing something rare, something we haven't found yet.
Like dark matter?
Exactly. Dark matter makes up most of the universe and we still don't know what it is. The Standard Model — the textbook of particle physics — doesn't explain it. The LHC has been very good at confirming what we already know, but finding dark matter requires more data.
The article mentions that some physicists are skeptical about building an even larger collider. Why would they doubt that?
Because the proposed Future Circular Collider would operate at lower energies than the LHC does now. It's designed for precision — measuring known quantities more accurately — not for discovering something entirely new. If you're spending $19 billion, you want more than a few extra decimal places.
That's a fair point. But couldn't precision measurements reveal something unexpected?
They could, in theory. But there's no guarantee. And in a world where budgets are tight and priorities are contested, that uncertainty matters. CERN operates on consensus, and consensus is expensive to build.
You mentioned that India has been part of CERN since the 1960s. What does that partnership look like?
India contributes scientists and expertise, but Sharma's point is that Indian industry should be involved in the design phase of future machines, not just the construction. If you wait until the building starts, you've already missed the chance to shape what gets built.
