Well, shoot. It’s been confirmed that early hints of a possible exotic new particle at the Large Hadron Collider in Switzerland have vanished. That disappointing news was announced this morning at a physics conference in Chicago.
Scientists working at CERN have found four new “tetraquark” particles comprised of the same four subatomic building blocks. These exotic particles don’t last very long, and they probably don’t play an important cosmological role, but the discovery reveals the surprising diversity of the tetraquark family.
We all know about the four fundamental forces of nature: gravity, electromagnetism, and the weak and strong forces between atoms. But could there be a fifth force still waiting to be discovered? A new experiment performed in Hungary suggests this may very well be the case.
When physicists at the Large Hadron Collider announced the detection of a possible, unexpected new particle last December, we advised caution, since most such hints go away when more data comes in. We won’t know for sure until this summer whether it’s real, or just random noise in the data masquerading as a signal.…
A fabric that bends and ripples under the weight of the stars. A clock that runs slower perched high in the mountains. Objects that only exist when they’re being watched. Endless tiny particles, swarming restlessly in the void.
A is of Accelerator, B is for Black hole, C is for Cryostat! Those are just a few of the particle physics lessons your kids will get from Symmetry Magazine’s new lovely, animated alphabet book that gives them an early start on science. Heck, you might learn a little something too.
Fermilab’s Tevatron collider officially retired in 2011 after a long and glorious history of scientific discovery. But the data from its final run is still yielding potentially exciting results. Physicists from the DZero collaboration have announced the discovery of a new particle, believed to be part of an exotic…
Particle physicist Fabiola Gianotti has become the first woman to head CERN, the organization based in Switzerland that is home to the Large Hadron Collider. She succeeds outgoing director-general Rolf Heuer, who oversaw the laboratory’s operations for the last seven years.
Earlier this week, physicists at the Large Hadron Collider announced they’d found tantalizing traces of a possible new fundamental particle — perhaps a heavier cousin of the Higgs boson, or the elusive graviton, a quantum carrier of the force of gravity.
Researchers at the Large Hadron Collider have seen the first traces of what they believe could be a new fundamental particle.
Basic physics suggests that electrons are essentially immortal. A fascinating experiment recently failed to overthrow this fundamental assumption. But the effort has produced a revised minimum lifespan for electrons: 60,000 yottayears, which is — get this — about five-quintillion times the current age of the Universe.
The nuclear strong force binds the smallest bits of matter together to form atoms, thereby making our material world possible. Physicists at Brookhaven National Laboratory have made the first-ever measurement of a similar strong force for antimatter — the mirror image of regular matter that lies at the heart of one of…
There’s a long and colorful history of people trying to unlock the secret of how the Egyptian pyramids were built—and possibly find hidden rooms and corridors, for good measure. And now, a new international project aims to peer through the stone walls of these ancient structures, using cosmic rays.
So you want to become a particle physicist, but you’re just not sure which area of research is best suited to your temperament. Never fear, special snowflakes! Symmetry magazine now has a fun personality quiz* to help you find out your physics destiny.
A team of Antarctic scientists has just verified the existence of cosmic neutrinos — tiny, energetic particles that might hail from far reaches of the Milky Way and beyond. And these ghostly little flecks of matter could hold the key to some of the deepest mysteries of the cosmos.
“Space is big,” said Douglas Adams. “You just won’t believe how vastly, hugely, mind-boggingly big it is.” But why must this be so? And why does our Universe exhibit such tremendous scale, from the very tiny to the extremely large? Here are some possible answers.
After two years of upgrades, the world’s largest particle accelerator is back in business. And it’s already bashing subatomic particles together at higher energies than ever before to probe the most fundamental questions about the nature of the universe.
