LHC shuts down for the weekend (correction: make that months)
The LHC is forced to shut down after helium leaks into the tunnel. It will be closed for the weekend as scientists try to figure out the cause.
Has someone come back from the future to keep the LHC from fully switching on? We’ll probably never know.
Update: The LHC will be closed for two months while the damaged section is repaired.
