Pushing back the Frontiers of Knowledge

Curiosity and the pursuit of scientific knowledge are the foundations upon which CERN was founded. When the Laboratory first opened its doors in 1954, the understanding of the subatomic world was far from complete. Today, we know that all visible matter in the Universe is composed of a remarkably small number of particles, governed by four fundamental forces. CERN has played a vital role in this adventure.

Have we reached the end of the road in understanding nature? Far from it.

The coming years and decades will see some exciting developments in accelerator technology with the high-luminosity upgrade of the Large Hadron Collider (HL-LHC), which aims to to crank up the performance of the LHC after 2029. The HL-LHC will allow physicists to study known mechanisms, such as the Higgs boson, in much greater detail and to observe rare new phenomena that might be revealed.
