A very rare event seen at CERN
Why it matters
CERN has a big machine in Switzerland. It crashes tiny particles together.
- Scientists saw a very rare event. They waited 42 years for it. A particle (a very small piece) broke into two smaller ones.
- Only 1 in 10 billion of these particles breaks this way (total count). They found about 12 cases in 10 years of data (total count).
- This is a breakthrough (a big new success). It can lead to finding new particles. It is not a full discovery yet. More proof is needed.
