What flings mysteriously powerful particles called 'cosmic rays' at Earth?

By Robert Lea published 13 May 26

High-energy cosmic rays, 10 million times more powerful than particles accelerated in Earth's strongest atom smasher, may hide a superheavy secret that is the key to unlocking a 60-year-old puzzle.

'Like putting a microscope into the core of the sun': World's 1st space-based neutrino detector launches to orbit

By Tereza Pultarova published 13 May 26

The world's first space-based neutrino detector launched to space this month to study elusive neutrino particles that constantly bombard Earth.

Large Hadron Collider gives scientists their best look yet at conditions right after the Big Bang

By Robert Lea published 8 April 26

"This is the first time we have observed, for a large interval in momentum and for multiple species, this flow pattern in a subset of proton collisions in which an unusually large number of particles are produced."

Is time a fundamental part of reality? A quiet revolution in physics suggests not

By Florian Neukart published 22 February 26

It feels so obvious that time moves forward that questioning it can seem almost pointless.

Scientists hunt for origins of the mysterious 'sun goddess' particle

By Robert Lea published 16 February 26

Scientists have used a novel new approach to discover the potential origins of the sun goddess particle Amaterasu, the second most energetic cosmic ray ever to be detected striking Earth.

Large Hadron Collider reveals 'primordial soup' of the early universe was surprisingly soupy

Waiter, there's a quark in my soup!

Does physics say that free will doesn't exist?

By Paul Sutter published 29 December 25

At first glance, it seems like our understanding of physics forbids free will.

How the 'delayed choice quantum eraser' experiment got us to rethink reality

By Paul Sutter published 20 December 25

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

Why is the universe made of matter? These 'ghost particle' experiments could help us find out

By Sharmila Kuthunur published 4 December 25

A new joint analysis from the NOvA and T2K experiments offers the most precise look yet at neutrino behavior, bringing scientists closer to understanding why the universe is made of matter.

Physicists and philosophers have long struggled to understand the nature of time: Here's why

By Daryl Janzen published 29 November 25

Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots.
