Item#: SCP-3426
Object Class: Keter
Laconic Containment Procedures: Until the nature of SCP-3426 is known, Any known form of containment is not yet established. Humanity's advancement of scientific understanding such as unified physics theory or infinitely sustainable energy should be impeded and slowed down at any cost.
Laconic Description: SCP-3426 is a pretty horrifying answer to the Fermi Paradox. It describes a phenomenon that renders any sufficiently advanced civilization extinct.
The phenomenon triggers whenever a species becomes a Type-1 Kardashev civilization, aka being able to harness the entirety of their planet's power, create a proven theory of everything, the formation of a group that catalogs anomalies, or similar scientific advancements.
The phenomenon manifests in different ways but it always manifests in a way to completely destroy the species, even going so far as to degrade the laws of physics and/or reality itself. Because of this the Foundation is purposefully holding the technological progress of humanity back until they can figure out a way to avoid this fate.
