Antimatter, annihilation and a universe that shouldn't exist

Antimatter is at the heart of one of the great mysteries in modern physics — why our universe has stuff in it.

Big, beautiful photos of insane physics experiments chasing the 'ghost particle'

Scientists call it the 'ghost particle'. Meet the neutrino, which scientists hope will help them answer dozens of critical questions about the Universe.

Discovered: ultra-elusive, super-energetic neutrinos from far-away galaxy

The capture of a burst of high-energy neutrinos from a far-off galaxy heralds a new era in astrophysics.

Scientists at Fermilab Are About to Start Shooting Neutrinos Through the Earth

Fermilab outside Chicago will soon begin its Deep Underground Neutrino Experiment (DUNE), and what it hopes to accomplish is as brilliant and confusing as the book of its namesake.

Electron 'Lifespan' Is At Least 5 Quintillion Times The Age Of The Universe

Basic physics suggests that electrons are essentially immortal. A fascinating experiment recently failed to overthrow this fundamental assumption.

Dance like a neutrino: quantum scheme to simulate neutrino oscillations

The behavior of some of the most elusive particles in the known universe can be simulated using three atoms in a lab, researchers say.

'Faster-than-light' particles fade after cross-check

Neutrinos do not go faster than light, according to fresh measurements of a test last year that had suggested the particles broke the Universe

Researchers send 'wireless' message using neutrinos

(PhysOrg.com) -- A group of scientists led by researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos – nearly massless particles that travel at almost the speed of light. The message was sent through 240 meters of stone and said simply, "Neutrino."

First results from Daya Bay find new kind of neutrino transformation

The Daya Bay Reactor Neutrino Experiment, a multinational collaboration operating in the south of China, today reported the first results of its search for the last, most elusive piece of a long-standing puzzle: how is it that neutrinos can appear to vanish as they travel? The surprising answer opens a gateway to a new understanding of fundamental physics and may eventually solve the riddle of why there is far more ordinary matter than antimatter in the universe today.

Underwater neutrino detector will be second-largest structure ever built

The hunt for elusive neutrinos will soon get its largest and most powerful tool yet: the enormous KM3NeT telescope, currently under development by a consortium of 40 institutions from ten European countries. Once completed KM3NeT will be the second-largest structure ever made by humans, after the Great Wall of China, and taller than the Burj Khalifa in Dubai… but submerged beneath 3,200 feet of ocean!

OPERA neutrino experiment on breaking speed of light

Based on extensive feedback from the broader particle physics community on its neutrino time-of-flight measurements presented at CERN on September 23, the OPERA

Can neutrinos move faster than light?

If it's true, it will mark the biggest discovery in physics in the past half-century: Elusive, nearly massive subatomic particles called neutrinos appear to travel just faster than light, a team of physicists in Europe reports. If so, the observation would wreck Einstein's theory of special relativity, which demands that nothing can travel faster than light.

Scientists take fresh look at 'faster-than-light' experiment

Scientists who threw down the gauntlet to physics by reporting particles that broke the Universe
