How Long to Fall Through Earth? Faster Than Thought

Set aside 38 minutes and 11 seconds, says new study

(Newser) - It's a common hypothetical in physics classrooms: How long would it take to fall through a tunnel from one side of the Earth to the other? The new answer: 38 minutes and 11 seconds, reports Science . The result is courtesy of McGill University graduate student Alexander Klotz, whose calculations... More »

Physicists Invent New Pasta Shape

Anelloni could help them understand physics mystery

(Newser) - It's food for thought—quite literally. A pair of scientists in the UK have turned a physics problem into an Italian-style dish. They invented anelloni, whose name is based on the Italian word for ring, as a way of studying ring-shaped polymers, Phys.org reports. Polymers, the site notes,... More »

Jackson Pollock: Master of Physics?

Artist's paintings exploited paint as non-Newtonian fluid

(Newser) - Jackson Pollock's remarkable works have long mesmerized art lovers and scientists alike. Scientists were particularly impressed to learn back in 2011 that Pollock's work took advantage of fluid dynamics even before physicists studied the principle. Now, using an experimental technique, researchers in Mexico City have been able to... More »

Why Dogs Are Messy Drinkers —But Cats Aren't

Canines 'smash their tongues on water': researcher

(Newser) - When grabbing a drink, neither cats nor dogs are able to squeeze their cheeks closed to suck up liquids the way humans can. Instead, they have to use their tongues in processes researchers didn't understand until recently, Reuters reports. Cats, researchers found a few years back , put their tongues... More »

Physicist Paid Only $200 for His Nobel-Winning Invention

Company that Shuji Nakamura worked for also sued him for trade infringement

(Newser) - Shuji Nakamura's world got a little bit brighter yesterday morning when he found out he'd won the Nobel Prize in physics , along with Japan's Isamu Akasaki and Hiroshi Amano. But even though McKinsey guesses that Nakamura's invention—blue light-emitting-diodes, or LEDs—will be worth about $80... More »

Professor: I've Got Proof Black Holes Don't Exist

Math just doesn't add up, argues UNC physicist

(Newser) - Massive stars don't just fade away, they collapse into black holes, right? Even non-scientists have at least a vague notion of these mysterious forces of nature out there in deep space. Well, sorry to spoil everybody's fun, but a physics professor at the University of North Carolina says... More »

World's Next Timekeeper: Quantum Superclock?

Atomic clocks would meet quantum entanglement

(Newser) - Sick of missing appointments by milliseconds because of inaccurate atomic clocks? Researchers say they could use quantum physics to create a timekeeper so accurate it could help explain some of the mysteries of time itself. The "quantum superclock" would involve multiple atomic clocks, each in its own satellite orbiting... More »

Physicists: We Know How to Turn Light Into Matter

And it could happen within a year, they say

(Newser) - Scientists are on the brink of turning light into matter—a process first theorized in 1934 but then described by the very men behind the idea as "hopeless to try." The subatomic particles the Imperial College London physicists say they've figured out how to produce will not... More »

Big News in World's Longest Experiment

Drop of pitch falls after 13 years of waiting

(Newser) - In what is surely one of the most gripping experiments currently underway, scientists in Australia have been watching a beaker containing pitch, a tar derivative, since 1927. The researchers' goal in the planet's longest-running experiment—which holds a place in the Guinness Book of World Records—is to show... More »

CERN Wants New Collider, 62 Miles Long

Contraption could be 4 times size of Large Hadron Collider

(Newser) - The Large Hadron Collider has only been in "full swing" for three years, notes a leading CERN physicist—but since planning for it began in 1983, it's already time to start thinking about what's next. In the case of the European particle physics organization, that means considering... More »

All the Universe Is ... Just a Hologram?

New physics research might prove Maldacena's hologram theory

(Newser) - Prepare for a head trip: The universe may actually be a hologram and everything you see an illusion, according to new research that could prove gravity comes from thin, vibrating strings—holograms of events in a simpler, flatter cosmos. It was an idea first put forth by physicist Juan Maldacena... More »

Physicists Need New Accelerator for 'God Particle'

Japan is expected to be home to $8B project

(Newser) - The good news for physicists is that they've finally found the elusive Higgs boson . The bad news is that to truly study it in the hope of unlocking the mysteries of the universe, they're going to need a whole new particle accelerator, reports NPR . And the type of... More »

Physicists Unravel Mystery of Usain Bolt's Speed

He uses astonishing power and energy to overcome drag

(Newser) - Usain Bolt is a big guy as far as sprinters go, and his 6-foot-5 frame doesn't exactly make him a model of aerodynamic perfection. But as his time of 9.58 seconds in a 100-meter race in 2009 proves, he is the fastest human on the planet. Even... More »

US, French Quantum Physicists Win Nobel

Their work could lead to super-fast computer

(Newser) - Two quantum physicists have won this year's Nobel Prize for Physics for their work measuring quantum particles, which could one day lead to an ultra-fast computer. Before the work of French scientist Serge Haroche and American David Wineland, researchers didn't think it was possible to measure the particles... More »

SpeechJammer, Ponytail Physics Win Ig Nobels

One weird science winner found brain activity in dead fish

(Newser) - Teams that scanned the brains of dead fish and studied the physics of coffee sloshing and ponytails were among the winners at this year's Ig Nobel celebration of strange scientific research. The acoustics prize went to the Japanese inventors of the SpeechJammer , a device that repeats a speaker's... More »

Higgs Find Kind of a Letdown

Could be Large Hadron Collider's last major discovery

(Newser) - The discovery of the Higgs boson deserves applause—but it also brings a touch of sadness to at least one leading physicist. It's probably "the last major discovery that could be made in a particle accelerator in our generation," writes Stephen Wolfram at his blog . And instead... More »

Hottest Temp Ever Created by Man: 7 Trillion Degrees

Physicists produced it during quest to learn more about Big Bang

(Newser) - A team of New York physicists has managed to smash gold ions into a quark-gluon plasma much like the one believed to have existed in the milliseconds after the Big Bang—and in the process broken the Guinness World Record for the hottest man-made temperature ever recorded. The plasma hit... More »

Physicist Gets Out of Ticket With 4-Page Paper

Dmitri Krioukov proves offense impossible

(Newser) - Dmitri Krioukov is a physicist at UC San Diego, so when he got pulled over for failure to stop at a stop sign, he knew what to do: write a four-page paper explaining how his alleged offense was simply not possible according to the laws of physics. Krioukov's paper... More »

Einstein Safe: Neutrinos Do Not Break Light Speed

New experiment shows particles at identical speed with light

(Newser) - Einstein's theory apparently remains untouchable, and flabbergasted theoretical physicists can cease hyperventilating: Neutrinos do not exceed the speed of light, but they do appear to travel at the same speed as light, according to the results of a recent experiment. The new data confirm Einstein's foundational ideas and... More »

Einstein Wrong? Maybe Just Faulty Wiring

A simple loose cord may explain last year's controversy

(Newser) - More evidence that last year's furor over the accuracy of Albert Einstein's work got blown way out of proportion: Physicists believed they'd seen particles traveling faster than light , a phenomenon that would disprove the theory of relativity. But the controversial observations may have been the result of... More »
