Physicists Just Detected a Very Odd Particle That Isn't a Particle at All

It sounds like the start of a very bad physics riddle: I'm a particle that really isn't; I vanish before I can even be detected, yet can be seen. I break your understanding of physics but don't overhaul your knowledge. Who am I? It's an odderon, a particle that's even...

The Quest to Find One of the Most Elusive Particle Decays in the Universe

Transmuting one element into another (usually gold, of course) was the stuff of fevered dreams and fanciful imaginations for alchemists way back in the day. It turns out that nature does it all the time without any help from us — though not usually into gold. This natural alchemy, called...

What Makes the Strong Force So Special?

All four known forces of nature have their own unique place. Gravity, electromagnetism, weak nuclear, strong nuclear: Each one governing some little domain of our lives. While our everyday experiences are dominated by the gravity of the Earth and the electromagnetism of light and fridge magnets, the twin nuclear forces...

The World's Largest Atom Smasher Could Be Tweaked to Hunt 'Dark World' Particles

Scientists may have a new way to peer into physics' dark world. In a new paper, theoretical physicists say they have a new plan for searching for theoretical particles that, so far, have never been observed. These particles, dubbed long-lived particles, or LLPs, could be a window into dark matter...

Inside Giant Atom Smasher, Physicists See the Impossible: Light Interacting with Light

In case you didn't realize it, photons are tiny little bits of light. In fact, they're the smallest bit of light possible. When you turn on a lamp, gigantic numbers of photons spring from that bulb and slam into your eyes, where they are absorbed by your retina and turned...

Faster-Than-Light Particles Emit Superbright Gamma Rays that Circle Pulsars

Charged particles travel faster than light through the quantum vacuum of space that surrounds pulsars. As these electrons and protons fly by pulsars, they create the ultrabright gamma-ray flashes emitted by the rapidly twirling neutron stars, new research reveals. These gamma-rays, called Cherenkov emissions, are also found in powerful particle...

Physicists Search for Monstrous Higgs Particle. It Could Seal the Fate of the Universe.

We all know and love the Higgs boson — which to physicists' chagrin has been mistakenly tagged in the media as the God particle — a subatomic particle first spotted in the Large Hadron Collider (LHC) back in 2012. That particle is a piece of a field that permeates all...

These Odd 'Quasiparticles' Could Finally Unmask Dark Matter

About 80% of all the matter in the cosmos is of a form completely unknown to current physics. We call it dark matter, because as best we can tell it's…dark. Experiments around the world are attempting to capture a stray dark matter particle in hopes of understanding it, but so...

'Evil-Genius' Neutrino Gun Could Finally Unmask the Tiniest Particles in the Universe

Neutrinos are perhaps the most underrated particles known to humankind. Physicist, smart guy and smart aleck Wolfgang Pauli first proposed their existence in 1930 as a missing puzzle piece — certain nuclear reactions had more going in than they had coming out. Pauli reasoned that something tiny and invisible had...

Physicists Finally Narrowed Down the Mass of the Tiniest 'Ghost Particle' in the Universe

We're full of neutrinos all the time. They're everywhere, nearly undetectable, flitting through normal matter. We barely know anything about them — not even how heavy they are. But we do know that neutrinos have the potential to alter the shape of the entire universe. And because they have that...

A Rail Gun the Size of Manhattan Could Reveal the Secrets of the Higgs Boson

Nobody messes with the Large Hadron Collider. It's the supreme particle smasher of the present age, and nothing can touch its energy capabilities or ability to study the frontiers of physics. But all glory is transitory, and nothing lasts forever. Eventually, somewhere around 2035, the lights at this 17-mile-long (27...

A Strange New Higgs Particle May Have Stolen the Antimatter from Our Universe

Why our universe is swirling with more matter than its bizarre counterpart antimatter — and why we exist at all — is one of the most perplexing puzzles of modern physics. Somehow, when the universe was incredibly young, almost all the antimatter disappeared, leaving just the normal stuff. Theorists have...

Is a New Particle Changing the Fate of the Universe?

Astronomers around the world are in a bit of a tizzy because they can't seem to agree about how fast the universe is expanding. Ever since our universe emerged from an explosion of a tiny speck of infinite density and gravity, it has been ballooning, and not at a steady...

Mysterious 'Particle X17' Could Carry a Newfound Fifth Force of Nature, But Most Experts Are Skeptical

Our universe is governed by four fundamental forces. At least that's what physicists have long thought. Now, however, new research suggests that there's a fifth force, a discovery that could upend much of modern physics. On Oct. 23, researchers at the Institute of Nuclear Research in Hungary published a new...

Oddball sexaquark particles could be immortal, if they exist at all

After decades of poking around in the math behind the glue holding the innards of all matter together, physicists have found a strange hypothetical particle, one that has never appeared in any experiment. Called a sexaquark, the oddball is made up of a funky arrangement of six quarks of various...
