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.
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.
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.
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 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.
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.
This seems like a straightforward enough question, but we actually have no idea whether gravity repels or attracts antimatter, all because we've never actually managed to trap enough antimatter at once to test it. That may be about to change.
The Extreme Light Infrastructure is a new project that will build three incredibly powerful new lasers. Capable of creating energy pulses 20 times more powerful than anything before, these new lasers could help us probe the world of weird physics.
Are we ever going to use antimatter to drive a starship?
Antimatter seems impossibly exotic, something that exists only in particle accelerators or in cosmic events many light-years away. But the next time there's a big thunderstorm, look up at the sky: you're looking at the creation of natural antimatter bursts.
Physics is still grappling with two basic questions about the nature of matter: why is there more matter than antimatter, and where and what is all the dark matter? Meet the hypothetical X particle, the potential answer to both questions.
Get ready for that warp drive spaceship, because we are now one step closer to it. After creating antihydrogen in their antiproton decelerator, scientists at CERN have been able to trap antimatter for the first time in history.
Positronium is a particle created when you bind together an electron and its antimatter counterpart, the positron. It doesn't interact with other atoms in the way we would expect, and this discovery could help us solve the universe's biggest mysteries.
