Particle Physics

One award was for a medical procedure that incapacitated thousands of people.
Cherenkov neutrino radiation
Before we discovered gravitational waves, multi-messenger astronomy got its start with light and particles arriving from the same event.
From the tiniest subatomic scales to the grandest cosmic ones, solving any of these puzzles could unlock our understanding of the Universe.
heavy neutral atom
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
schwinger effect
In our common experience, you can't get something for nothing. In the quantum realm, something really can emerge from nothing.
consciousness
At a fundamental level, only a few particles and forces govern all of reality. How do their combinations create human consciousness?
An astrophysicist explains these shortcuts through space-time.
If your computer crashes, it might be due to a star that exploded somewhere in the Universe millions of years ago.
Quantum mechanics forces us to toss out the old, reliable ways in which we make sense of our everyday reality.
Magnetic monopoles began as a mere theoretical curiosity. They might hold the key to understanding so much more.
lasers
Lasers are all around you. This ubiquitous technology came from our understanding of quantum physics.
Searching for dark matter, the XENON collaboration found absolutely nothing out of the ordinary. Here's why that's an extraordinary feat.
There's a speed limit to the Universe: the speed of light in a vacuum. Want to beat the speed of light? Try going through a medium!
Scientists have found three new examples of a very exotic form of matter made of quarks. They can yield insights into the early Universe.
The neutrino is the most ghostly, rarely-interacting particle in all the Standard Model. How well can we truly make "beams" out of them?
LHC insides
The way to understand the earliest moments of creation is to recreate those conditions and study them. Why would we stop now?
Higgs boson
On July 4, we celebrate the tenth anniversary of the discovery of the Higgs boson, the missing piece of the Standard Model of particle physics.
neutrinos
Experiments cannot confirm what theory predicts about neutrinos. And particle physicists have no idea why.
particle accelerator
Giant particle accelerators aren't a waste of money. They are essential for understanding the Universe.
standard model color
The Standard Model of elementary particles has three nearly identical copies of particles: generations. And nobody knows why.
A next-generation LHC++ could cost $100 billion. Here's why such a machine could end up being a massive waste of money.
The weirdness begs for an interpretation.
standard model structure
The Standard Model may or may not be in trouble, but particle physics definitely needs saving. Here's what the new LHC can do.
tevatron standard model
Fermilab's TeVatron just released the best mass measurement of the W-boson, ever. Here's what doesn't add up.
el gordo colliding galaxy cluster
The laws of physics state that you can't create or destroy matter without also creating or destroying an equal amount of antimatter. So how are we here?
chernobyl radiation
The rhetorical fallout is greater than the radioactive fallout.
Einstein
More than any other of Einstein's equations, E = mc² is the most recognizable to people. But what does it all mean?
Comet C/2014 Q2 Lovejoy
“When molecules misbehave, it can lead to great insight.”
chirality
Life is possible because of asymmetries, such as an imbalance between matter and antimatter and the "handedness" (chirality) of molecules.
