Is time a fundamental part of reality? A quiet revolution in physics suggests not
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
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
Using the world's most powerful particle accelerator, the Large Hadron Collider, scientists have found that the quark-gluon plasma that filled the universe just after the Big Bang really was a primordial "soup."
Does physics say that free will doesn’t exist?
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
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
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
Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots.
‘Ghost particles’ can zoom through you without a trace. Scientists are getting to the bottom of this cosmic mystery
Scientists are searching for answers in the cosmic mystery of ghost particles known as neutrinos.
Virtual particles: How physicists’ clever bookkeeping trick could underlie reality
A physicist explains the idea of virtual particles and why they are important to study.
What is the weak nuclear force and why is it important?
The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all.
