Physicists test if they can load antimatter on a truck

Posted on July 20, 2025 by

Physicists in Europe have reported that it’s possible to transport charged particles on a truck for four hours without disturbing them in any way. This seemingly run-of-the-mill announcement, reported in Nature on May 14, actually contains within its details the … Continue reading →

A new path to explaining the absence of antimatter

Posted on December 10, 2023 by

Our universe was believed to have been created with equal quantities of matter and antimatter, only for antimatter to completely disappear over time. We know that matter and antimatter can annihilate each other but we don’t know how matter came … Continue reading →

The Large Hadron Collider is back online, ready to shift from the “what” of reality to “why”

Posted on March 13, 2015 by

The world’s single largest science experiment will restart on March 23 after a two-year break. Scientists and administrators at the European Organization for Nuclear Research – known by its French acronym CERN – have announced the status of the agency’s upgrades on its Large … Continue reading →

Which way does antimatter swing?

Posted on May 1, 2013 by

In our universe, matter is king: it makes up everything. Its constituents are incredibly tiny particles – smaller than even the protons and neutrons they constitute – and they work together with nature’s forces to make up… everything. There was … Continue reading →

Where’s all the antimatter? New CERN results show the way.

Posted on April 27, 2013 by

If you look outside your window at the clouds, the stars, the planets, all that you will see is made of matter. However, when the universe was born, there were equal amounts of matter and antimatter. So where has all … Continue reading →

On meson decay-modes in studying CP violation

Posted on November 20, 2012 by

In particle physics, CPT symmetry is an attribute of the universe that is held as fundamentally true by quantum field theory (QFT). It states that the laws of physics should not be changed and the opposite of all allowed motions … Continue reading →
