The Large Hadron Collider (LHC) — the world's most powerful particle accelerator, a machine that smashes particles together to study the building blocks of the Universe — has been switched off as CERN, the European laboratory for particle physics, begins a major upgrade programme. 

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

Scientists at the Large Hadron Collider announce the discovery of a new particle called the pentaquark.

The Large Hadron Collider has re-started scientific investigations after a two-year pause.

The Large Hadron Collider smashes protons together for the first time since early 2013.
