One of the great scientific puzzles of our time is why we live in a universe full of matter rather than antimatter. Wherever we look, we observe that matter dominates over antimatter, yet we believe that matter and antimatter were created in equal amounts soon after the Big Bang. To reconcile these two facts there must be some difference in the way matter and antimatter behave.
A new study may help answer one of the universe’s biggest mysteries.
A variation of the classic double-slit experiment is applied to a positron for the first time
It is assumed, but not experimentally verified, that antimatter masses will behave the same as matter masses in a gravitational field.
For the first time, physicists at CERN have observed a benchmark atomic energy transition in anithydrogen, a major step toward cooling and manipulating the basic form of antimatter.
Physicists at CERN are working to determine why the equal amounts of matter and antimatter in the universe haven’t annihilated each other.
New results show a difference in the way neutrinos and antineutrinos behave, which could help explain why there is so much matter in the universe.
A new chapter in antimatter research.
A team of international astrophysicists led by The Australian National University (ANU) has shown how most of the antimatter in the Milky Way forms.
You and me, we’re matter. Everyone you know is matter. Everything on Earth, spare a few particles, is matter. Most of the things in space are matter. But we don’t have convincing reasons why there should be so much more matter than antimatter. So where’s all the antimatter?
