For nearly 25 years, we thought we knew how the Universe would end. Now, new measurements point to a profoundly different conclusion.

How is matter different from mass? These and other questions about the deepest levels of physics, answered inside.

Imagine looking in the mirror and finding your familiar face reflected back as you've always known it. But as you look more closely, as you precisely examine that mirror image, subtle distortions emerge. The glass itself remains flawless, but real and fundamental differences exist between you and the face that lives on the other side of the looking glass.

In the Standard Model (SM) of particle physics, gluons are the fundamental particles mediating the strong interaction, as photons do in electromagnetic interactions.

Scientists potentially uncovered a glueball particle, an enigmatic entity believed to be made entirely of the strong nuclear forces gluons.

One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up.

A top physicist is ‘confident’ Chinese scientists can build the world’s largest collider, as debate of the project continues.

“I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very well, but I just don’t believe there is a big cosmic conspiracy that created this incredible thing that has nothing to do with the real world.” -Edward Witten

Domain walls, long a divisive topic in physics, may be ideal explanations for some bizarre cosmic quirks

The open CMS detector during the second long shutdown of CERN’s accelerator complex. (Image: CERN) When we look at ourselves in a mirror, we see a virtual twin, identical in every detail except with left and right inverted. In particle physics, a transformation in which charge–parity (CP) symmetry is respected swaps a particle with the mirror image of its antimatter particle, which has opposite properties such as electric charge. The physical laws that govern nature don’t respect CP symmet...
