Theory:

apocoliptic event begins with:

• failure of the liquid helium equipment
• then failure of superconducting magnets, which keep proton flow in place
• then failure to control proton beam
• then [rare chance of] proton collision near tube edge causing black hole
• then tube collapse due to black hole-consumed tube wall
• then atmosphere ventilation into black hole.

apocoliptic event ends with:

• eventual planet absorption into black hole.
