A truck makes a historic trip around CERN’s facility on the France-Switzerland border, transporting the world’s most expensive material for the first time.
The antimatter inside is made by CERN’s enormous particle accelerator, and then antimatter particles are decelerated and captured for storage, shipment and study.
Antimatter is the mirror opposite of matter. The particular type of antimatter transported was 92 antiprotons, the negatively charged equivalent to the positively charged protons found in regular matter. This perplexing and precious material could hold the key to unlocking some of the largest looming mysteries remaining in physics, going back to the origins of our universe.

When matter and antimatter meet, they annihilate, turning most of their mass into pure energy. This reaction is the stuff of science fiction, powering spaceships and super weapons. However, with current technology, it would take billions of years to acquire enough antimatter to do any serious damage.
Annihilation is routine at CERN’s antimatter factory, happening on a small scale with individual particles and showing up as a line on a graph (pictured below).
This is what it looks like to scientists when matter and antimatter annihilate.
One of the mysteries the study of antimatter could solve is the reason why there’s so much more matter than antimatter in the observable universe, a question with roots going all the way back to the big bang.
So far, the science shows that matter and its antimatter equivalents are identical opposites in weight and magnetism. Stefan Ulmer, founder and spokesperson of the BASE experiment at CERN, believes more precise measurements could help find discrepancies which could hold the key.
The search for these discrepancies means that the antimatter particles must leave their birthplace at CERN because the same enormous magnets necessary to produce antimatter also make it difficult to study due to magnetic interference.
This may seem like a lot of work just to get more precise measurements of particles, but Ulmer says chasing answers to the biggest questions in science “makes you creative,” and this is his own version of heaven.

Frequently Asked Questions
A truck carried 92 antiprotons around CERN's facility on the France-Switzerland border, the first-ever shipment of antimatter, the world's most expensive material.
The enormous magnets needed to produce antimatter create magnetic interference, so particles must be moved away to the BASE experiment for precise measurements.
It could explain why there is so much more matter than antimatter in the universe, a question dating back to the Big Bang; so far they appear to be identical opposites in weight and magnetism.
No. With current technology it would take billions of years to gather enough antimatter for serious damage; annihilation at CERN happens with individual particles and shows up as a line on a graph.
