Simulation of lead ion collisions within the ALICE experiment at the Large Hadron Collider – one of eight detector experiments.
The Matter of Everything is a partial account of the history of physics, which leaves out a lot, including the story of some key women scientists.
Measuring the mass of W bosons took 10 years – and the result was not what physicists expected.

A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
Experiments at the Large Hadron Collider in Europe, like the ATLAS calorimeter seen here, are providing more accurate measurements of fundamental particles.
Physicists know a lot about the most fundamental properties of the universe, but they certainly don’t know everything. 2021 was a big year for physics – what was learned and what’s coming next?
Cern’s LHCb experiment has spotted more evidence of an anomaly in the standard model of physics.

Plus why the situation for Rohingya Muslims living in Bangladesh has gone from bad to worse. Listen to episode 9 of The Conversation Weekly podcast.
A long-sought crack in the Standard Model of particle physics may have been spotted.

The compact accelerators are 100 times smaller than traditional ones, and could easily fit inside hospitals and laboratories.
Is there anybody out there?
From the subatomic to the cosmic, don’t think for a second that we’re at the end of scientific history.

What shape is an electron? The answer, believe it or not, has implications for our understanding of the entire universe, and could reveal whether there are mysterious particles still to be discovered.

The Large Hadron Collider has generated mind-blowing science in the last decade – including the Higgs boson particle. Why is the LHC so important, and how will physicists use it in the years to come?
Map of all matter – most of which is invisible dark matter – between Earth and the edge of the observable universe.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.
CERN isn’t only breaking ground in physics, but also in open access to science.
It’s not enough to do groundbreaking research if the results are kept from the public. So CERN is making its results available to everyone via open access, showing how science should be done.
When particles collide.
New research has compared hydrogen and antihydrogen up to ten decimal places for the very first time.

Particle accelerators are helping to push forward the frontiers of theoretical physics but they’ve also had more impact on your everyday life than you realise.
Shaken not stirred …
Getting tellurium and phosphorus to form a molecule is stupidly hard and not very glamorous. Here’s why it’s worth the effort.
The Large Hadron Collider is playing a key role in enabling the collection of big data.
Big data is about processing large amounts of data. It is often associated with multiplicities of data. But the ability to generate data outpaces the ability to store it.
You can feel the weight of an object on Earth because of its mass. But what is mass?
We talk about mass all the time but what is it that actually gives an object mass? And why do some things have mass and others have no mass at all?
Neutrinos, we’re looking for you! Japan’s Super-Kamiokande detector.

The Nobel Prize-winning research on neutrinos is expected to push the boundaries of science and technology.
Dark matter is notoriously hard to detect, but a new experiment might finally shed light on this mysterious substance.
A new detector built deep underground in a gold mine will hopefully unravel the mystery of dark matter.
