10 Particle Detectors That Let Us See the Fabric of the Universe

All atoms are made up of subatomic particles. But not every particle spends its time locked into an atom. Some particles, like neutrinos, whiz around and through our oblivious bodies every day, while others are created when humans smash matter together at high speeds. To see these ultra-tiny particles, however, we… » 12/22/11 10:40am 12/22/11 10:40am

Faster-than-light neutrinos could be proof of extra dimensions

The recent announcement that neutrinos had been observed seemingly going faster than the speed of light sent shockwaves through the physics community. But there's one possible explanation that could keep Einstein's relativity intact and open up a whole new cosmos. » 9/28/11 1:36pm 9/28/11 1:36pm

Physicists explain controversial finding of faster-than-light particles

Yesterday, CERN physicists shocked the world with news of a scientific finding that could revolutionize the field of physics. The researchers claim to have observed what many had believed to be impossible: subatomic particles called neutrinos moving faster than the speed of light. » 9/23/11 3:15pm 9/23/11 3:15pm

Faster Than Light Neutrinos? Not So Fast

So did the folks at CERN really record neutrinos moving faster than light? Was Einstein wrong about light speed being a universal speed limit? It's too early to tell, and regular io9 contributor Dr. Dave Goldberg has some doubts. » 9/22/11 6:01pm 9/22/11 6:01pm

Mysterious changing neutrinos could explain why we don't live in an…

There's nothing in the laws of physics that actually requires matter to dominate antimatter, and yet all our observations of the universe suggest that that's the case. But some unexpected behavior by ghostly neutrino particles could solve the antimatter mystery. » 6/15/11 12:20pm 6/15/11 12:20pm

Giant ice caverns lead the hunt for exotic particles

This is a gigantic hole that's been melted into the South Pole. It's one of the 100 or so such vertical caves that have been punched into the Antarctic surface as part of the IceCube Neutrino Observatory, which is searching for tiny, almost massless particles known as neutrinos. This remarkable image reveals the… » 2/13/11 11:00am 2/13/11 11:00am

The Ultimate Field Guide to Subatomic Particles

Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles. » 9/16/10 10:44am 9/16/10 10:44am
