Officials at CERN, the world’s leading particle physics research institute, have announced plans to build the world’s largest particle accelerator. The machine is designed to smash molecules at near the speed of light, marking a significant step forward.
The proposed super collider, called the Future Circular Collider (FCC), will be a massive 91 km in length, three times the size of the Large Hadron Collider (LHC). This new machine will allow scientists to collide particles with greater precision and energy than ever before, potentially unraveling some of the universe’s biggest mysteries. These include the existence of more matter than antimatter, the nature of dark matter and energy, the presence of hidden extra dimensions, and the existence of the universe as a whole.
This step forward is significant because scientists hope the FCC will deepen their understanding of particle physics, aiming to explain why particles have specific masses and forces, and to uncover the nature of dark matter and dark energy, which account for 95% of the mass-energy of the universe. If approved, construction is expected to start by the mid-2030s, with the first stage operating around 2045, followed by a second phase extending research into the 2070s, establishing the FCC as a multigenerational scientific research effort.
Is bigger always better?
The importance of building larger particle accelerators lies in the fact that they can achieve higher collision energies. The goal is to put in enough energy to create new particles, such as the Higgs boson. The FCC aims to eventually reach seven times the collision energy of the LHC, offering a new and more complete understanding of physics.
The FCC will be capable of creating millions of Higgs particles, providing scientists with the opportunity to study them in great detail to understand how they interact with other particles. The Higgs boson is a carrier particle of the Higgs field that permeates space and gives mass to other particles, challenging previously held concepts about matter and mass.

In addition to providing deeper insight into the Higgs boson, the FCC will also aim to uncover the mechanisms by which the Higgs boson interacts and its significance in the universe. It is thought to have played a crucial role in the very beginning of the universe, nanoseconds after the big bang, by giving mass to matter as the universe grew and cooled. The influence of the Higgs boson is also relevant in understanding how the universe will end, as it affects the stability of the universe itself.
The FCC is expected to contribute to our understanding of whether the universe is in a stable or unstable state, providing the key to answering fundamental questions about the universe’s fate.

The FCC will play a crucial role in answering questions about the beginning and the end of the universe, with the expertise of notable scientists like Marcus Chown, professor Andy Parker, and Matthew McCullough. The expectation is that this new accelerator will contribute to an in-depth understanding of the fundamental physics that govern the universe and our place within it.
