The Large Hadron Collider (LHC) is the largest particle accelerator in the world. It will remain so for a long time, but CERN is already moving forward with plans to create a much larger collider.
CERN initially unveiled plans for the new accelerator in 2019. Now the center says it wants its construction plans to be approved within five years, which would put the collider up and running in the 2040s.
More precisely, during this period the installation will work as part of the first stage, when scientists will collide electrons and positrons. The second phase will be implemented only in the 2070s – then protons will begin to collide at the accelerator.
