The most powerful supercomputer simulation of the Universe is providing important insights into how matter is distributed across large scales. Surprisingly, a significant portion of matter resides outside of galaxies and in the cosmic voids that permeate the cosmos.
With over one million unregulated listings globally, critics of Airbnb have long said it’s only a matter of time before someone gets seriously hurt at one of the startup’s rentals. The most nightmarish scenario possible happened to a writer who is now coming forward: On Thanksgiving Day 2013, his father died from…
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.
Scientists have worked out an easy way of turning light into matter, a process thought to be impossible when first proposed 80 years ago. The proposed experiment would recreate events that occurred in the first 100 seconds of the Big Bang.
Back in 1934, a team of physicists came up with an idea for how one might create matter from light. Put simply, just slam two photons into each other to get an electron and a positron, a.k.a. matter. And now, some 80 years later, a team of physicists have a plan to carry out the experiment in real life.
There aren't enough humans on Earth to fill the Grand Canyon, and in a lifetime you don't produce enough saliva to even fill a swimming pool. That suggests that most things around us are countable or measurable: so how many things are there?
Not content with perhaps the biggest scientific discovery of the decade, scientists at the Large Hadron Collide continue to search for new particles—and now they've found one that seems to be an entirely new form of matter.
The latest science news out of Harvard and MIT sounds like a joke, but it's not. A team of physicists were fooling around with photons when they managed to get the particles to clump together to form a molecule, one that's unlike any other matter. And it behaves, they say, just like a lightsaber.
Myth: There are only three states of matter.
Usually, if you cool any substance down enough it will turn into a solid—the most stable state of matter that exists, according to traditional physics. But that could all be about to change, because researchers have discovered a weird new liquid state that's more stable than a solid crystal.
It started with a Kickstarter campaign. A couple of veteran science/technology journalists, Jim Giles and Bobbie Johnson, wanted a place where people could do investigative, long-form sci/tech writing. But most general interest magazines had cut down their feature sections, while science magazines didn't want to…
This newly created X-ray laser is just unimaginably powerful. It's a billion times brighter than any previous X-ray source, and it can probe hot dense matter at nearly four million degrees. This laser could unlock the secrets of the Sun.
In the 1980s, Daniel Schechtman theorized the existence of quasicrystals, bizarre materials between crystals and glasses that could never exist except in the laboratory. But now his impossible crystals have turned up in a Russian mountain.
Amidst the dubious news of neutrinos potentially traveling faster than light, it's easy to lose sight of something even stranger: neutrinos are in a constant identity crisis, oscillating between different types. Why is this? In this week's "Ask a Physicist" we'll find out.
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.
Spin liquids are an exotic state of matter that can only exist in the world of quantum mechanics. They're a strange mess of spin states and superpositions that forces magnetism and anti-magnetism to simultaneously exist in millions of different configurations.
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,…
