CERN HOPES TO START BUILDING £18BN LARGE HADRON COLLIDER REPLACEMENT THAT COULD SMASH PARTICLES TOGETHER WITH VASTLY MORE FORCE
The new machine will be four times as big and six times as powerful as the LHC

[size=19]CERN, the European Organisation for Nuclear Research, has set in motion plans to build a new 100-kilometer circular supercollider.[/size]
The Large Hadron Collider, by comparison, is 27 kilometers long.
It is currently being upgraded, and expected to restart again in May 2021 until 2024, before starting its final run in 2027.
The new machine, called the Future Circular Collider, would likely cost at least €21 billion. It is expected to be build in an underground location in Geneva by approximately 2038.
While final approval has not yet been given, CERN can take a more proactive approach in designing the collider, utilising resources otherwise allocated to alternative designs such as a linear eletron-positron collider or a muon accelerator, according to Nature.
