Physicists make a lot of statements about stuff they hope will happen, but might not happen in their lifetimes. One physicist, for example, thought that in certain cases, the incredibly common but hard-to-detect neutrino particles would somehow make entire atomic nuclei wiggle. He thought it a silly idea to even…
Particle physics is rarely a cheap-and-easy endeavor. Just think about the Large Hadron Collider, buried deep beneath the Swiss-French border—it cost over 13 billion dollars to find the Higgs Boson. Well, today at 4:20PM (nice), America is breaking ground on another enormous particle physics experiment.
You and me, we’re matter. Everyone you know is matter. Everything on Earth, spare a few particles, is matter. Most of the things in space are matter. But we don’t have convincing reasons why there should be so much more matter than antimatter. So where’s all the antimatter?
Fermilab outside Chicago will soon begin its Deep Underground Neutrino Experiment (DUNE), and what it hopes to accomplish is as brilliant and confusing as the book of its namesake.
The 2015 Nobel Prize in physics goes to Takaaki Kajita and Arthur B. McDonald for their work on neutrino oscillations. By tracking neutrinos in subterranean water tanks, the researchers watched neutrinos change flavour, in turn proving that the subatomic particles have mass.
It’s often said that we know less about Earth’s deep interior than we do about the surface of Mars (or at this point, maybe even Pluto). A new global map of subatomic particles called antineutrinos is helping to change that. It’s showing scientists just how radioactive our little Blue Marble is.
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.
In the 1950s, two physicists decided that they would find the elusive “neutrino” they’d heard so much about. They did find it — just not the way they first thought they would. And since they thought they would find it by exploding a nuclear bomb, that’s a good thing.
If you are using the Holborn Tube Station in England, you are getting to work via the site of an important part of physics history. It was home to an experiment that moved physics literally underground for the first time, all in the search for the elusive neutrino.
It was the heady days of the early 1900s, and radiation was all the rage. Researchers had just found a kind of radiation called "beta decay," and they discovered that it did something that seemed to smash one of the basic tenets of physics. Here's how the lowly neutrino saved the entire field.
Neutrinos are the ninjas of the universe. They don't interact with other particles very often, but when they do, they obliterate them. Until now. Scientists have observed a new way that neutrinos interact with the world.
It may seem as though every new day brings an announcement of a scientific breakthrough of the highest order. Should you freak out about every new record-breaking neutrino? In this week's "Ask a Physicist," we'll find out.
The University of Wisconsin's IceCube neutrino detection system has been quietly operating amid Antarctica's barren tundra for more than four years now. In that time, the fledgling detector has captured more than 100 cosmic neutrinos, many of which originated far outside our Milky Way galaxy. And if project leaders…
This picture isn't new, but it's nonetheless, amazing. You're looking at an image of the Sun taken at night through 8,000 miles of Earth's rocky matter. How is this wizardry possible? Because the Sun's neutrinos can pass through anything.
From intergalactic neutrinos and invisible brains, to the creation of miniature human "organoids," 2013 was a remarkable year for scientific discovery. Here are 17 of the biggest scientific breakthroughs, innovations and advances of 2013.
Italian physicists want to use 2,000 year-old lead ingots recovered from a Roman shipwreck to investigate the properties of dark matter and neutrinos. Roman lead is perfect for conducting such experiments owing to their purity and low levels of radioactivity. But archaeologists say it's ethically questionable research…
By drilling a 1.5 mile hole deep into an Antarctic glacier, physicists working at the IceCube South Pole Observatory have captured 28 extraterrestrial neutrinos — those mysterious and extremely powerful subatomic particles that can pass straight through solid matter. Welcome to an entirely new age of astronomy.
The title of the paper: "Can apparent superluminal neutrino speeds be explained as a quantum weak measurement?" The abstract? See for yourself:
