For two decades, researchers have studied soccer ball aerodynamics. Latest tests suggest the 2026 ball is more stable, but with a slightly shorter range.
A light particle can appear to leave a cloud of atoms before it enters – a new experiment, asking the atoms, confirms the light spends ‘negative time’ with them.
The behaviour of sub-atomic particles in the LHC seems to disagree with the Standard Model.
It would take hours to set up the perfect shot at the Texas Petawatt Laser facility. Once it fired, the beam released an incredible amount of energy.
Atomic clocks undergird modern timekeeping. A nuclear clock could be even more precise.
While direct evidence of multiple universes is hard to come by, indirect evidence raises intriguing possibilities.
Fiber optics allow you to search the internet, text your friends and check your social media feeds. They also have geological, security and manufacturing applications.
Taking inspiration from Leonardo da Vinci’s studies of friction, the ‘sneaker squeak’ question cuts to a deep problem in physics.
Behind the long-term climate projections that affect our lives sits one of the most remarkable scientific achievements of the modern era.
The electron is the tiniest particle. Then there are neutrinos, which are as small but may weigh more.
An avalanche during a storm in the Sierra Nevada killed at least eight skiers on a guided backcountry excursion.
Dark matter doesn’t seem to interact with the matter we can see and touch, so scientists look for it in unusual places, like faraway galaxies and underground detectors.
Athletes will use physics concepts such as friction and lift to their advantage on the world stage in the 2026 Olympic Games.
Watching, modeling and even playing winter sports help students internalize physics concepts, including acceleration, momentum and friction.
Here’s why some people believe we’re living in a computer simulation of reality – like a giant video game in which we’re all the characters.
Physicists long believed time was a basic feature of the universe. But it may just emerge from cosmic information.
Fire obviously isn’t a liquid or a solid. In fact, it’s not matter at all – it’s a process.
Winter jackets may seem simple, but sophisticated engineering allows them to keep body heat locked in, while staying breathable enough to let out sweat.
With a little help from science, it’s surprisingly easy to make crystal clear ice in your home freezer.
