The World's Biggest Physics Experiment Is About to Reboot 

The Large Hadron Collider (LHC) is the most audacious physics experiment in human history. Now scientists are about to restart the giant particle collider for a new set of experiments. Last time, they did the almost-impossible and found the Higgs Boson. This time, they might find something even more exciting. » 3/20/15 12:21pm 3/20/15 12:21pm

Physics Valentines (And Anti-Valentines), For Those You Love (And Hate)

The staff of symmetry has created a fun set of physics-themed Valentines to share with the people you love. And because ours is a universe that contains both matter and antimatter, they've created a complementary set of anti-Valentines, for the people you love to hate. » 2/11/15 4:30pm 2/11/15 4:30pm

This Interactive Map Could Help Astronomers Solve A 92-Year-Old Mystery

Since 1922, astronomers have been baffled as to the precise origin and composition of the diffuse interstellar bands seen through the Milky Way's stellar medium. This new interactive map doesn't solve the mystery, but it shows us exactly where these enigmatic molecules reside. » 1/13/15 12:40pm 1/13/15 12:40pm

These Are The Science Stories That Will Be Making News In 2015

The coming year is shaping up to be a rather extraordinary one. Over the next 12 months, we'll be visiting dwarf planets, unlocking the secrets of a 400,000-year-old genome, and resuming the hunt for exotic particles. Here are the science stories to look out for in 2015. » 1/08/15 11:15am 1/08/15 11:15am

A helium balloon fitted with six telescopes is currently floating over Antarctica. It's called SPIDER, and it could show what happened during the Big Bang. Scientists will use it to search for patterns of polarization that could have only been made in primordial light in the fractions of seconds after the birth of the… » 1/05/15 9:20am 1/05/15 9:20am

What Are All Those Quarks Doing in Your Body?

We're made of flesh and bone and fat, which are in turn made of protons and electrons, which are (mostly) made of quarks. Which, even though they are the most basic form of matter, are a minuscule percentage of your body's mass. Wait, what? Why do we have so much more mass than what we're made of? » 12/23/14 11:30am 12/23/14 11:30am

An "Impenetrable Barrier" Protects The Earth From Killer Electrons

It appears that our planet's built-in force field is much stronger than we thought. Scientists studying the Van Allen belts have discovered the presence of a nearly impenetrable barrier that prevents some of the fastest and most powerful "ultrarelativistic" electrons from reaching the surface. » 11/27/14 1:00pm 11/27/14 1:00pm

Two New Subatomic Particles Have Been Discovered At CERN

Particle physicists working at the Large Hadron Collider have detected two new subatomic particles that were predicted to exist but never seen. The discovery of the two new baryon particles stands to deepen our understanding of the universe. » 11/19/14 12:40pm 11/19/14 12:40pm

Freakishly Compact Particle Accelerators Could Revolutionize Physics

Experiments at the SLAC National Accelerator Laboratory in the U.S. have taken us a step forward in developing a technology that could significantly reduce the size of particle accelerators and allow scientists to accelerate particles more rapidly than conventional accelerators at a much smaller size. » 11/06/14 2:20pm 11/06/14 2:20pm

Curious Signal Could Be Dark Matter Pouring From The Sun's Core

This could be historic: Astronomers from Leicester University have detected a strange signal in the X-ray spectrum that appears to be a signature of 'axions' — a hypothetical dark matter particle. It could take years to confirm, but this may be the first direct detection and identification of dark matter. » 10/17/14 8:00am 10/17/14 8:00am

Physicists Have Found A Particle That's Also Its Own Antiparticle

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. » 10/03/14 8:30am 10/03/14 8:30am

Why The Higgs Boson Should Have Crushed the Universe

This may seem a little far fetched — but if our understanding of the physics behind the recently-discovered Higgs boson is correct, our universe shouldn't exist. » 6/25/14 6:00pm 6/25/14 6:00pm

Physicists Design A Collider That Turns Light Into Matter

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. » 5/20/14 7:20am 5/20/14 7:20am

Recently Discovered Big Bang "Smoking Gun" Could Be A Bust

Eight weeks ago, physicists announced that they'd discovered evidence of gravitational waves in the early universe, potential proof that our universe began with a bang and inflated from there. But the most significant cosmological discovery in years might just be an experimental artifact. » 5/13/14 7:20am 5/13/14 7:20am

Scientists Detect A Particle That Could Be A New Form Of Matter

Physicists working at the Large Hadron Collider have spotted a long sought-after exotic particle that's the strongest evidence yet for a new form of matter called a tetraquark. Here's what the discovery could mean to astrophysics. » 4/11/14 6:00pm 4/11/14 6:00pm

What Cold War nuclear weapons can tell us about art fraud

The identification of fakes and forgeries is a basic issue that has always raised controversy. This is unsurprising, of course – the enormous sums garnered by top paintings would turn to dust as soon as a question as to their authenticity arose. » 2/26/14 9:00am 2/26/14 9:00am

Physics experiment suggests magnets with only one pole actually exist

Though predicted to exist, magnetic monopoles — hypothetical elementary particles with only one magnetic pole — have never been detected by scientists. But physicists have just accomplished the next best thing by actually creating their own synthetic version of these bizarre magnetic particles in the lab. » 1/31/14 9:00am 1/31/14 9:00am

Is a ring of dark matter making the Earth heavier than it should be?

After measuring the orbits of GPS satellites, a geophysicist came the startling conclusion that the Earth is heavier than it's supposed to be. The reason, he says, may be due to a halo of dark matter surrounding the Earth at the equator. » 1/06/14 8:30am 1/06/14 8:30am

Yes, electrons are perfectly round -- and that's a problem

Bad news, everyone! New measurements show that electrons are perfectly round. This is a problem because it means something's still seriously wrong with a critical theory that's supposed to tell us why the universe exists. » 12/20/13 4:00pm 12/20/13 4:00pm

New calculations suggest the Universe could collapse at any time

All things being equal, the universe is set to continually expand, eventually ripping itself to shreds in about 22 billion years. But Danish scientists say an expanding bubble of existential doom could crush the Universe into a tiny ball. And crazily, the odds of this collapse is higher than previously thought. » 12/13/13 12:40pm 12/13/13 12:40pm
