Researchers detect particle signals at record smallest scale

Scientists at CERN have detected signals from an extremely tiny region of matter called the zeptoverse. The discovery was made in November 2026 at the Large Hadron Collider, a machine on the Swiss-French border that smashes atoms apart to study what is inside them.

The zeptoverse is about 100 billion times smaller than a single atom. It is the smallest scale that scientists have ever explored. The research was led by Dr. Harry Cliff from Cambridge University.

Scientists think that particles at this scale may react more strongly to dark matter. Dark matter is an invisible substance that fills most of the universe, but we still do not understand it well. The findings could help explain how dark matter affects the tiny particles inside atoms.
