What Does a Particle Collider Sound Like?

Scientists explore the limits of physics by pumping energy into components of atoms, such as electrons and protons, accelerating them to nearly the speed of light, and slamming the beams of particles together in hopes of discovering something new. You can imagine that this process gets quite noisy. Read More >>

Scientists Recreate Hallmark Quantum Physics Experiment Using Antimatter

Scientists recreated one of the most important experiments in the history of physics – but this time, they used antimatter instead of regular matter. Read More >>

Avengers: Endgame Has Some Nerve Making Fun of Time Travel Movies

Because real-world time travel back and forth between the past and present is not (yet) possible, and the underlying science behind our working theories as to how it might one day be possible can be difficult to grasp, our ideas about it have largely been shaped by fictional depictions in books, television shows and movies like Avengers: Endgame.

Hubble Measurements Confirm There’s Something Weird About How the Universe Is Expanding

New results from the Hubble Space Telescope have deepened one of the biggest mysteries in astronomy. Read More >>

These Are Bubbles Made of Sand

Engineers observed bubbles of sand moving within other sand, like oil droplets through water, in a first-of-its-kind observation. Read More >>

The Quest for the Most Elusive Material in Physics

Zack Geballe spent months screwing together pairs of polished diamonds at the Carnegie Institution for Science’s Geophysical Laboratory. Theory predicted that squeezed between the diamonds’ tips could be one of the most miraculous substances of modern physics—a material that, at near room temperature, could transport electricity without losing power. He just needed to get the samples to Argonne National Lab in the US city of Chicago to heat them up with laser pulses. Read More >>

What Do Nuclear Bomb Explosions Sound Like?

On July 16, 1945, scientists first unleashed energy stored at the centre of the atomic nucleus, causing a massive explosion in the New Mexican desert. That bomb’s successors would kill several hundred thousand people, permanently alter the course of international relations, and instill a constant sense of fear across the world for the following generations.

Why Doesn’t the Black Hole Image Look Like the One From Interstellar?

No one knew what a black hole looked like before yesterday. Sure, we thought we knew, thanks to simulations and the now-famous black hole featured in the movie Interstellar. Read More >>

Pyroclastic Flows May Spread Swift Death on a Cushion of Air

Scientists think they’ve figured out how pyroclastic flows, fast-moving bringers of death during volcanic events, can travel such incredible distances and speeds despite the friction between the volcanic material and the ground. Read More >>

Why Twisted Graphene Is One of the Most Exciting Physics Stories of the Year

Just a year ago, scientists presented results that seemed almost too good to be true: Carbon sheets only a single atom thick, called graphene, took on a pair of important physical properties when they were twisted at just the right “magic” angle relative to one another. If the atmosphere this month at the world’s largest physics conference was any indication, twisted graphene has now spawned an entirely new field of physics research. Read More >>

Why an Incredible New CERN Observation Has Physicists Popping Champagne

Scientists have announced the observation of “CP violation in a D0 meson” at CERN, a discovery that will appear in physics textbooks for years to come. You’re probably wondering what exactly it means. Read More >>

Indian Scientists Measure 1.3-Billion-Volt Thunderstorm, the Strongest on Record

Scientists in India observed the highest-voltage thunderstorm ever documented with the help of a subatomic particle you might not hear much about: the muon. Read More >>

Mercury, Not Venus, Is the Closest Planet to Earth

A team of scientists just demonstrated something that might shock you: Mercury, not Venus, is the closest planet to Earth on average. Read More >>

How Heavy Is the Milky Way?

From stars, planets, and asteroids through to black holes and invisible dark matter, our galaxy is packed with a lot of stuff. The total mass of all this celestial stuff, however, is not something astronomers have been able to agree upon. Read More >>

Astronomers Around the World Are Training in Case a Giant Asteroid Threatens Earth

On 12 October 2017, a 20-metre asteroid passed just 50,000 kilometres (31,000 miles) from Earth. For weeks, dozens of astronomers from labs around the world mobilised, measuring everything they could about the asteroid in preparation for an impact. Read More >>
