Item #: SCP-1964-EX
Object Class: Explained
Laconic Containment Procedures: There are no feasible methods of containment and public knowledge of it is impossible to suppress.
Laconic Description: SCP-1964 is the phenomenon of mass in quantum physics. This seems to break the fact that the Foundation's gauge bosons are required to have unbroken gauge symmetry and hence the universe might collapse due to this discrepancy.
The Foundation began asking SCPs about the effect but there was no specific answer given. They began using a redacted SCP to try to reverse the phenomenon. Eventually, SCP-1964 became an understood non-anomalous phenomenon, which turns out to be the Higgs Boson.
