Item #: SCP-4010
Object Class: Keter
Special Containment Procedures: Don't act out SCP-4010 under any circumstances.
Description: SCP-4010 is a phenomenon that destroys reality if someone creates a full timeline of the universe, including all the reality warping and temporal manipulation that has rewrote parts of it.
Researcher Madeleine Sailer is instructed to create a timeline of the SCP database and inadvertently performs SCP-4010. In the end, the Foundation universe falls apart and turns into our, the readers' universe. To restore it to some semblance of the original timeline, Sailer posts SCP-173 on 4chan and kick-starts the SCP wiki as we know it today.
Additional Context: SCP-4010 was an entry in the SCP-4000 Contest, where it won 30th place.
