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…
The best way to study the subatomic particles that make up the most fundamental building blocks of our universe is, of course, to smash them into each other with as much energy as possible. And now physicists at SLAC National Accelerator Laboratory say they’ve found a better way to do that.
Where the hell did the antimatter come from? That’s what atmospheric scientist Joseph Dwyer has been trying to figure out for the past six years, after his research plane accidentally flew through a thunderstorm into a cloud of antimatter in 2009.
Everyone's favorite mega-machine, the Large Hadron Collider at CERN, is meant to help humans some of the most basic questions about the nature of our world. How it goes about this is—in a word—complex. But part of it involves a bit of good old-fashioned (kind of) photography.
Antimatter is treated like an exotic substance, fraught with danger, which can only be harnessed in the future to send star ships to warp speed. However, this isn't true. We use antimatter right now, and we use it in hospitals. Learn how PET scans use positrons to help you.
You might think that matter and antimatter aren't the best of friends, cancelling each other out when they come into contact—but you'd be wrong. In fact, researchers have now discovered a particle that's made up of both.
Back in 1937, an Italian physicist predicted the existence of a single, stable particle that could be both matter and antimatter. Nearly 80 years later, a Princeton University research team has actually found it.
MinutePhysics is a YouTube channel that aims to deliver complex science to your brain in short, easily digestible videos. The channel has hundreds of eye-opening bits of science you can click through, but the team's latest video seemed ambitious—explaining the concepts of antimatter in only three minutes.
According to theoretical physicists, a quarter of a gram's worth of matter should release five kilotons of energy if it comes into contact with its anti-matter counterpart. Yet we don't see this happening on Earth or elsewhere in space. What's going on?
Antimatter, the evil-twin-like opposite to every particle in the universe, is pretty wild stuff. While in the sci-fi world it powers warp drives, here in the frustrating confines of reality we still haven't figured out how to harness it. But thanks to some mad scientists at the Large Hadron Collider, now we know what…
Remember that time you mixed vinegar and baking soda and decided you wanted to be a scientist? Maybe you should have followed through. Then you could have been one of the guys that just developed a tabletop "gun" that creates positrons by shooting lasers at gold.
Antimatter is mysterious, dangerous, and rare. In fiction, it's at the core of Isaac Asimov's positronic brains, the engines on the Enterprise, and the bomb in Dan Brown's Angels and Demons. But in the real world, antimatter is fairly mundane stuff. If the entire universe turned into antimatter, we'd barely notice. Or…
While the Large Hadron Collider is looking for the Higgs boson, we're on the verge of two huge antimatter-related breakthroughs. One could finally solve the universe's oldest mystery, while the other could reveal strange new particles that are perfect for quantum computers.
Let's face it: It's only a matter of time until Mars comes after us. We've got lots of water. It doesn't. We've got life. It doesn't. All this might have been okay, but then we alerted Mars to our presence with our various satellites and rovers, and now it's just a matter of time. Here are some ways we might destroy…
The Large Hadron Collider is constantly on the hunt for "new physics" — discoveries that confound and expand our current understanding of the universe... and it may have found one in the decay patterns of a subatomic particle and its antimatter counterpart.
Of anti-protons! While it's not as visually cool as what Saturn has going for it, this is still an important development, even if we can't technically "see" the ring with our primitive Earthling eyes.
Cosmic rays bring our planet a steady stream of protons, electrons, and other particles. As these collide with nuclei in the upper atmosphere, they create new particles, including antiprotons. And some of this antimatter is sticking around above our world.
If you're like the rest of us, you're almost certainly made of matter. But where did all that delicious, gooey matter come from? In this In this week's "Ask a Physicist" we'll find out.
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.
Scientists working on the Antihydrogen Laser Physics Apparatus (ALPHA) near Geneva, Switzerland did something no other scientists have done. They stored atoms of antihydrogen for 1000 seconds (~16 minutes) which is 10,000 times longer than they've ever done before. By trapping and observing antimatter for that long,…
