There may be ways to check if our universe is just simulated entertainment for an advanced, alien species.
The majority of nations voted to scrap leap seconds – the little jumps added to UTC time to keep it aligned with Earth’s rotation. What can we expect moving forward?
Every World Cup, Adidas introduces a new ball, and this year’s is called the Al Rihla.

Adidas releases a new ball for every World Cup. At the highest level of play, a ball that behaves in unexpected ways can throw players off. A sports physicist explains the science of this year’s ball.
Fireflies’ synchronized light shows have fascinated observers for ages.
Synchrony is ubiquitous throughout the universe. But physicists’ equations predicted there could also be erratic exceptions marching to their own beat. Now they’ve been spotted in firefly swarms.
A new particle accelerator at Michigan State University is set to discover thousands of never-before-seen isotopes.
Facility for Rare Isotope Beams
A new particle accelerator has just begun operation. It is the most powerful accelerator of its kind on Earth and will allow physicists to study some of the rarest matter in the universe.
Marcel Proust on a French postage stamp.
From electricity to X-rays, the Doppler Effect and even quantum theory, Proust’s writing is littered with physics references.
Radiation really is everywhere – and it’s not at all as spooky or dangerous as we often think.
Devices like this experimental apparatus can produce pairs of photons that are linked, or ‘entangled’.

Quantum mechanics raised tough philosophical questions about the nature of the world – and a physicist named John Bell figured out how experiments could answer them.
When two particles are entangled, the state of one is tied to the state of the other.

A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.
Participants at a Paris-Saclay workshop on educational innovation work on ideas for teaching in a forest.
To think about new ways of transmitting science and to really innovate how we teach, the first step is creating an appropriate dialogue format. From there, everything becomes possible.
Strangely behaving matter could one day explain some of the mysteries of space.
Twisted laser light may help launch a revolution in technology.
There’s a lot of science behind the natural forces that let this guy work his magic at the beach.
From capillary forces to sand grain shape, the simple mix of sand and water hides the complexity within.
Simulation of lead ion collisions within the ALICE experiment at the Large Hadron Collider – one of eight detector experiments.
The Matter of Everything is a partial account of the history of physics, which leaves out a lot, including the story of some key women scientists.
TRAPPIST-1e is a rocky exoplanet in the habitable zone of a star 40 light-years from Earth and may have water and clouds, as depicted in this artist’s impression.
Life on Earth has dramatically changed the chemistry of the planet. Astronomers will measure light that bounces off distant planets to look for similar clues that they host life.

A physicist explains how atoms arrange themselves into molecules – and how scientists are able to image these tiny bits of matter that make up everything around you.
Our curiosity about time travel is thousands of years old.
Theories exploring the possibility of time travel rely on the existence of types of matter and energy that we do not understand yet.
Researchers used a radio telescope in New Mexico to study a particularly interesting fast radio burst.
Astronomers studying fast radio bursts recently discovered one that repeats, has a persistent radio signal and originated in a galaxy much closer than it should have.
Protons and neutrons in an atom’s nucleus can be arranged in different configurations, creating nuclear isomers.
