High Energy Physics
From the tiniest subatomic scales to the grandest cosmic structures of all, everything that exists depends on two things: charge and mass.
When we divide matter into its fundamental, indivisible components, are those particles truly point-like, or is there a finite minimum size?
From LIGO, there weren't enough neutron star-neutron star mergers to account for our heavy elements. With a JWST surprise, maybe they can.
Matter is made up largely of atoms, where atomic nuclei can contain up to 100 protons or more. But how were the heaviest elements made?
A proton is the only stable example of a particle composed of three quarks. But inside the proton, gluons, not quarks, dominate.
Here in our Universe, stars shine brightly, providing light and heat to planets, moons, and more. But some objects get even hotter, by far.
The electromagnetic force can be attractive, repulsive, or "bendy," but is always mediated by the photon. How does one particle do it all?
A recent measurement has simultaneously settled an ongoing scientific debate while puzzling scientists.
Matt Strassler's journey into fundamental physics culminates in a brilliant explanation of the Higgs field. Enjoy this exclusive interview.
The closest known star that will soon undergo a core-collapse supernova is Betelgeuse, just 640 light-years away. Here's what we'll observe.
We have very specific predictions for how particles ought to decay. When we look at B-mesons all together, something vital doesn't add up.
"A person’s mass is made not of 'stuff' in the way we normally think about it, but rather our mass is made of energy."
The last naked-eye Milky Way supernova happened way back in 1604. With today's detectors, the next one could solve the dark matter mystery.
The race to find dark matter could grow more complex with high-energy neutrino interference.
Black holes are the most massive individual objects, spanning up to a light-day across. So how do they make jets that affect the cosmic web?
Why hasn’t matter fallen apart over billions of years? The mystery might start with protons.
LHC scientists just showed that spooky quantum entanglement applies to the highest-energy, shortest-lived particles of all: top quarks.
CERN scientists achieved record-breaking accuracy in mapping the mass of a key particle in the Standard Model.
A recent experiment challenges the leading dark matter theory and hints at new directions for uncovering one of the Universe's biggest mysteries.
The observation that everything we know is made out of matter and not antimatter is one of nature's greatest puzzles. Will we ever solve it?
Scientific surprises, driven by experiment, are often how science advances. But more often than not, they’re just bad science.
Researchers at the Brookhaven National Laboratory recently created the heaviest exotic antimatter hypernucleus ever observed.
DUNE is designed to detect the Universe's most antisocial particle: the neutrino.
The largest particle accelerator and collider ever built is the Large Hadron Collider at CERN. Why not go much, much bigger?
More than any other equation in physics, E = mc² is recognizable and profound. But what do we actually learn about reality from it?
Quarks and leptons are the smallest known subatomic particles. Does the Standard Model allow for an even smaller layer of matter to exist?
Today, the Large Hadron Collider is the most powerful particle physics experiment in history. What would a new, successor collider teach us?
A recent paper in the journal Physical Review Letters claims to prove that a "kugelblitz" is not possible.
Often viewed as a purely theoretical, calculational tool only, direct observation of the Lamb Shift proved their very real existence.
The properties of a ghostly particle called a neutrino are coming into focus.
