This Experiment Will Shoot Ghostly Particles Through Earth, Answer Why We Exist

The study of the subatomic world has revolutionized our understanding of the laws of the universe and given humanity unprecedented insights into deep questions. Historically, these questions have been in the philosophical realm: How did the universe come into existence? Why is the universe the way it is? Why is...

For Tiny Light Particles, 'Before' and 'After' Mean Nothing

Beneath the surface of the familiar world is a smaller, quantum world that defies our fundamental ideas of time and space. In this mini world, the concepts of before and after dissolve, such that two events can both precede and succeed each other. In other words, event A can occur...

Atom Smasher Detects Hints of New Unstable Particle

The Large Hadron Collider (LHC), the world's largest atom smasher, just discovered at least two previously unknown particles. The 17-mile (27 kilometers) underground ring near Geneva recently discovered two baryons and a hint of another particle, according to a statement from the European Organization for Nuclear Research (CERN), which runs...

Physicist Who Coined 'God Particle' Dies. And a Great Voice for Science Is Stilled.

It is a sad day in science. Dr. Leon Lederman has passed away at the age of 96. Leon was a legend in the world of particle physics. Known perhaps most for coining the phrase “The God Particle,” in his book of the same name, Leon had a distinguished scientific...

Physicists Model Electrons in Unprecedented Detail — Spoiler Alert: They're Round

Electrons are extremely round, and some physicists are not pleased about it. A new experiment captured the most detailed view of electrons to date, using lasers to reveal evidence of particles surrounding the particles, researchers reported in a new study. By lighting up molecules, the scientists were able to interpret...

What Do Shrink-Wrapped Thanksgiving Turkeys and the Higgs Boson Have in Common?

(Inside Science) — Each Thanksgiving, millions of Americans tote turkeys home from the store. If you find yourself plopping a fresh, shrink-wrapped bird into your cart, you can thank particle physicists for the sturdy, shelf life-extending packaging. That's because the food industry makes shrink wrap using a tool first developed...

Humanity's Largest Atom Smasher Takes a Pause, Will Wake Up Again in 2021

Particles: Breathe easy. Scientists at the world's largest particle collider have no plans to smash you together until spring 2021. When you update your computer, you usually have to turn it off and back on again. The same thing is going on right now at the Large Hadron Collider (LHC)...

In 10 Years, the Large Hadron Collider Was a Smash — with More Discoveries to Come

Back in 2008, a beam of protons first zipped around the Large Hadron Collider (LHC), the world's most powerful particle accelerator. Now, a decade later, it is time to take stock of what we've learned thanks to this facility and what lies ahead. This accounting includes both future research that...

What a Tiny Electron Reveals About the Structure of the Universe

What is the shape of an electron? If you recall pictures from your high school science books, the answer seems quite clear: an electron is a small ball of negative charge that is smaller than an atom. This, however, is quite far from the truth. The electron is commonly known...

Why Physicists Are Hunting the Strangest of the Ghost Particles

Every single second of every single day, you are being bombarded by trillions upon trillions of subatomic particles, showering down from the depths of space. They blow through you with the strength of a cosmic hurricane, blasting in at nearly the speed of light. They're coming from all over the...

Physicists Want to Build an Even More Powerful Atom Smasher at CERN

The universe is filled with particles we don't know about that are governed by rules we don't yet understand. But by smashing familiar particles together at nearly the speed of light using large machines aptly named particle accelerators, physicists can sometimes glimpse the invisible. Now, they have a plan to...

Hyperfast Shock Waves from a Supernova Heat Atoms to Blazing-Hot Temperatures

On Feb. 23, 1987, the light from a giant, exploding star reached Earth. The event, which took place in the Large Magellanic Cloud, a small galaxy 168,000 light-years away that circles our Milky Way, was the closest supernova to occur in nearly 400 years, and the first since the invention...

A 'Dragon Aurora' Appeared in the Sky Over Iceland, and NASA Is a Little Confused

A gargantuan green dragon hisses in the sky over Iceland. Either Game of Thrones really upped its production budget for its final season, or the sun belched a barrage of charged particles into our atmosphere again. As much as any of us would like to see a real dragon breathe...

Physicists Just Solved a 35-Year-Old Mystery Hidden Inside Atomic Cores

Here's a mysterious truth that scientists have known since 1983: Protons and neutrons act differently when they're inside an atom, versus floating freely through space. Specifically, the subatomic particles that make up those protons and neutrons, called quarks, slow down massively once they're confined to a nucleus in an atom....

Where Are All the 'Sparticles' That Could Explain What's Wrong with the Universe?

The governing theory of particle physics explains everything about the subatomic world … except for the parts that it doesn't. And unfortunately, there aren't a lot of flattering adjectives that can be applied to the so-called Standard Model. Built up bit by bit over the course of decades, this theory...
