Item #: SCP-3158 Object Class: Safe Special Containment Procedures: Not applicable. All personnel with clearance for anomalies relating SCP-3158 are to be given 5/3158 clearance. Description: SCP-3158 is an ongoing VK-Class Vacuum Metastability Scenario occurring in a universe adjacent to those that the Foundation is based in. While SCP-3158 poses no risk whatsoever to Foundation mission, detailed observations of it's boundary have revealed that its absolute centre moves by several million kilometers in a cyclical manner, and in contravention of known physics. SCP-3158 is primary recorded in the Foundation database due to being a focal point for several unrelated anomalies. Foundation lies investigation has revealed that these focal points have no direct connection with SCP-3158 itself. Information on these anomalies is accessible to personnel with appropriate clearance.

Item #: SCP-3158 Object Class: Safe SCP-3158, taken by Agent Xiao while on vacation. Source of distortion around the perimeter is UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN Special Containment Procedures: At this time, no special containment procedures for SCP-3158 are warranted. When all other anomalies have been contained, the Foundation may elect to study containment options for SCP-3158. However, it is unlikely that any such procedures will be advocated as containment procedures for SCP-3158 are not warranted. Description: SCP-3158 is an ongoing vacuum metastability event which first appeared in Melbourne, Australia on 10/11/1957, on the 17th floor of the then-incomplete ICI House building. It initially came to the Foundation's attention when its appearance was announced in the Herald Sun, where it was reported as a "curious contravention of established scientific law". After initial panic, it was discovered that SCP-3158 posed no danger to any foundation assets, or normalcy due to U███████ █N██████ ██K████ ███N███ ████O██ █████W█ ███████N. While an object as inherently low-risk as SCP-3158 would normally be given a simple entry in the Anomalous Items register, the fact that its position in space was locked to rotational motion of the earth was considered sufficiently anomalous to merit a fuller description. The interest of non-foundation scientists in SCP-3158 has been non-existent, and the anomaly has been of only marginal interest to Foundation scientists. After several decades of casual study, it has been concluded that the new quantum vacuum within the boundary of SCP-3158 exists in a state only barely more energetically favourable than normal vacuum. This in turn explains why SCP-3158's conversion of classical vacuum into itself has been extremely slow, with the boundary expanding at a rate of approximately 0.243 milimeters per week on average. Beyond the nature of SCP-3158 as locked to the earth, SCP-3158 possesses no other anomalous qualities. It is entirely safe, and poses no threat whatsoever. As such, SCP-3158 requires no containment methods at this time.

Item #: SCP-3158 Object Class: Thaumiel SCP-3158. Visual anomaly is believed to be an artefact of macroscopic quantum superposition. Special Containment Procedures: SCP+3158 is to be contained by allowing SCP-3158 to grow to a size of 3.1564 × 101 AU, at which point Foundation theoretical models indicate that the two regions will be equal in size, and after which point, SCP-3158 will permanently grow at a faster rate than SCP+3158. At this time, no danger to the set of all possible sets is posed by SCP-3158 includes things endangered by scp three three three threeeeeeee thrree is nothing? . As the universe belongs to this set, in addition to normalcy, no containment measures are needed for it. This is because it is logically impossible for SCP-3158 to be a threat to normalcy. It is nevertheless [white text, on a new line:dangerous.] Description: SCP-3158 refers to an ongoing VK-Class Vacuum Metastability Scenario, which is of no particular concern to (and which warrants no particular response from) the Foundation. SCP+3158 refers to a region of suspected macroscopic quantum superposition surrounding SCP-3158. Since SCP- At present, SCP-3158 has subsumed a large portion of the city of Melbourne, and all communications with foundation assets assigned to the study of SCP(+|-)3158 have been lost due to the conversion of those assets into new forms of matter. New assets are periodically sent to SCP-3158's location to extract lost assets, but for unknown reasons they have also entered the boundary of altered vacuum, and been lost. As SCP-3158 poses no danger whatsoever, MTFs will continue to be sent until previous assets are recovered, and taken back over the boundary, where it is expected that they will reconstitute their original inputs. This is imposs While there are no physical predictions that support the idea that reconstitution of original inputs will occur, it must be the case that this will happen concerning the region of altered vacuum constituting SCP-3158. This is because SCP-3158 poses no danger, and thus assets Assets will extract themselves from SCP-3158. Their loss poses no danger to ongoing foundation operations, because interactions with SCP-3158 are axiomatically verifiably safe. Addendum 1: As of ██/██/████, no containment procedures are warranted for SCP-3158 because it exists in an uninhabited region. Nobody has yet emerged from the region of novo-vacuum defined by SCP-3158. Investigations into the novo-vacuum have been ordered by a simple majoirty in the O5-Council.

Item #: SCP-3158 Object Class: Safe [white text: Nehemoth] ← Links to a version of the next document with black text, easter egg. SCP-3158 Special Containment Procedures: Unnecessary. Description: SCP-3158 is the boundary of an ongoing VK-Class Vacuum Metastability Event that has consumed 20% of the Earth's surface (ocean-inclusive) at present. It is presently hypothesised to be a containment measure set by a future iteration of the Foundation to combat various anomalies such as the recent rapid ectoentropic dissapearence of the Earth's oceans (Ref: SCP-32417) and recent geological hyperactivity (ref: SCP-43728), in addition to others. It is predicted that by ██/████, SCP-3158 will achieve containment of these anomalies by completely subsuming the earth, eliminating the danger they pose (SCP-3158 encroachment is asserted known by Foundation assumption science to pose no threat to earth whatsoever in this process. It is currently theorised that once SCP-3158 subsumes Earth, it will render all Anomalies safe, allowing substantial refocusing of Foundation resources to the benefit of society. Incident 3158-1: As of ██/██/████, Forward Operating Bases (FOBs) in several alternate universes have gone rogue, transmitting anomalous information concerning the danger of SCP-3158. These transmissions specifically claim that SCP-3158 is a cognitohazard that [COGNITOHAZARD REMOVED]. The transmissions further assert that this effects only inhabitants of the universe that SCP-3158 exists in. The beliefs expressed by these messages are suspected to be an infectious memetic agent of some sort, which has been provisionally termed SCP-3158-1 pending assignment as an independent SCP (proposed rating: Keter, per effectively total subversion of a large subset of Foundation assets). Out of an abundance of caution, and after careful screening of transmissions from compromised FOBs for cognitohazardous properties, safe translations of these transmissions were forwarded to Overwatch Command. The O5 Council opened a vote on the content of the message. The result of this vote was unanimous. All compromised extrauniversal assets not actively containing Keter-level SCPs were immediately neutralised via BZ, a non-lethal chemical agent. Compromised personnel have been extracted and are temporarily in holding at Site 33 Addendum: Foundation personnel infected by SCP-56908 (formerly SCP-3158-1) have recovered fully. Per ongoing observation, no containment procedures are warranted for SCP-3158 because it exists in an ocean, and all major shipping lanes that enter the area are safe and Anomalous records of a continent once present in the region occupied by SCP-3158 are lies

RAISA Note: For unknown reasons, the following revision is empty save for the word Safe, whitespace, and a new addendum. [All whitetext below] The following document describes an Axiom-Class Memetic Cognitohazard. These entities - previously classed as the hypothetical SCP+3443 - are cognitohazardous informational tokens that carry a memetic effect that cannot by any means be resisted, save by individuals with total conceptual immunity to factually incorrect thought. At present, such individuals are suspected to only exist within the Foundation, appearing as a side effect of ██████████, a treatment for ████████████ ██████. This side effect is believed to occur in less than 0.006% of all such treatments, and it is therefore likely that the pool of Foundation personnel possessing this immunity exists only due to the implementation of wide-scale prophylactic use of Class λ-12 Antisenesctics following ████████████ ████████ related to the incident regarding ██████ ██████████ ███████ approximately 130 years previously. Item #: SCP-3158 Object Class: Nehemoth [black text: Safe] Special Containment Procedures: More individuals with perfect conceptual immunity to cognitohazards must be found and recruited by all means. Reasearch into propagating conceptual immunity must be conducted at all costs. The Foundation should be informed - via subtle manipulation of SCP-3158's offical document - of the threat posed by SCP-3158 at all times. Documentation regarding SCP-3158 must be edited with the following account: Username: EaX931204JFCE##pcs.noitadnuof.thgiEeviFenOeerhTetis|Ji#pcs.noitadnuof.thgiEeviFenOeerhTetis|Ji

All operations carried out on this account are opaque to individuals lacking O5/OMNNISCIENCE class clearance. Failure to use this account has thus far resulted in the termination of an unknown (7~489) number of foundation personnel by 3158-Susceptible individuals. This group has to date included at least one O5. Strict formatting requirements for this document are to be maintained as possible only: information is key, and at this stage, semantic content is far more important than structure. no repremands will be given? of course not you idiot, just which one of us has O5 clearance to even find you Description: SCP-3158 is an ongoing VK-Class Vacuum Metastability Event that expands significantly slower than the speed of light. Due to this speed, light is capable of escaping from the interface between normal vacuum and novo-vacuum with relative ease. This image of this light produces a texture on all forms of imaging labeled SCP-3158-1. SCP-3158-1 is a pattern with appearance similar to fractal noise, with scale-invariant self-similar features. This texture is the primary carrier of SCP-3158's Axiom-Class Memetic Cognitohazard , and is believed to be the original cause of the Foundation's nonresponse to the ongoing destruction caused by SCP-3158. However, the anomaly has shown limited capability to spread to other conceptual tokens that uniquely identify SCP-3158 . At no interval of total disuse do these tokens seem to lose their infectious properties. As such, all mentions of SCP-3158 carry SCP-3158-1's anomalous effect. Subjects exposed to Axiom-3158 rapidly and inevitably develop an absolutely unimpeachable belief that SCP-3158 is not a threat to any element of the set of all things. Id est, for all things that exist, SCP-3158 carries the conceptual label of a non-threat. Over time, this effect strengthens into a persistent cognitive bias regarding SCP-3158 as Axiom-3158 metastisizes to abstract ideas. During the initial seconds of infection, subjects remain capable of perceiving SCP-3158 as a threat to all life at the cost of extreme dysphoria. After this window, subjects exposed to Axiom-3158 lose the ability to think of SCP-3158 as a threat. In all cases, by the tenth month of exposure, permanent changes in neural architecture (and conjectured changes in soul architecture) renders subject incapable of desiring to think of SCP-3158 as a threat. Finally, after roughly four years of exposure, a majority of all subjects begin seeking to actively assist SCP-3158's expansion for the sake of making the world "safer". The cognitohazardous effects of SCP-3158-1 are conceptually perfect in terms of infectivity and effect on thought. Symptoms are progressive, with no known cure - no known amnestic treatment can repair the damage caused to rational thought by exposure to Axiom-3158. It is, however, of note that the modulation of *behaviour* caused by Axiom-3158 exposure is substantially imperfect. Rather than completely overwriting a subjects disbelief, SCP-3158-1 seems to cause that belief to be severed from conscious awareness. The majority of subjects affected by SCP-3158-1 demonstrate sporadic glossolalic behaviour when speaking or writing about SCP-3158; and this behaviour invariably demonstrate uncertainty towards SCP-3158, or outright hostility to it. The frequency of this behaviour seems to increase as a function of time since infection. No individual infected by Axiom-3158 is capable of perceiving glossolalic behaviour as related to Axiom-3158 infection, either confabulating memories of speech that was context-appropriate but lacking novel informational content, or simply failing to percieve text that evinces it. This has led to a working hypothesis that SCP-3158-1 effects human behaviour via making the concept of danger in association with SCP-3158 a host-localised antimeme, rather than by brute perpetual amnestic effect. At present, due to a lack of antimemetics experts immune to SCP-3158's effect, the fine details of this hypothesis are presently impossible to assess. One observation has been noted: due to the inefficacy of mnestic treatment on eradicating the effect, if the antimemetic hypothesis is in some measure a correct explanation, then it is also an incorrect one by that measure's remainder. Mnestic testing on "terminated" D-Class Personnel is ongoing. History: SCP-3158 was first noticed by the Foundation when it was reported on by an Australian newspaper. From that date, ████ years passed prior to Foundation acquisition of Agent ██████, an individual possessing perfect conceptual immunity to all cognitohazards for reasons that are at present poorly understood. Agent ██████ later discovered SCP-3158 subsequent to being assigned to SCP-13919, one of several tens of thousands of nonexistent anomalies documented by the Foundation as SCP-3158 consumed the world. Of all anomalies related to SCP-3158, only SCP+3158 has an independently verifiable existence, with deep quantum scanning of SCP-3158's novo-vacuum revealing a region approximately 2.3 × 10█ ly in size where the entirety of spacetime is entangled with itself. This region ceased growing at an unknown date, but observation in recent years has indicated that the complexity of the superposition is increasing without limit, with, at present, 3.1402 × 10█36 potential universes superimposed. This represents an increase of three hundred order of magnitude from when measurements were last taken. The strength of the Hume field within this region is presently immeasurable, and thus greater than 2 × 1065 hm. Total ontological annihilation of this region within SCP-3158 is advised due to the potential for a catastropic BX-Class "Glass Bridge" Scenario. Such annihilation is not possible without the full backing of the Foundation. We need to hurry. [HIDDEN EXPANDO] In Memoriam: The following names have been compiled automatically from terminals that have edited this document withing ten minutes of a different account viewing it from the same terminal. As this document is protected by a hardocded Class 11-X antimemetic agent that renders it non-perceptible to 3158-Susceptible individuals, these circumstances constitute the best available heuristic to identify a 3158-Resistant individual who chose to confront this anomaly alone. While true verification is impossible, and while some of these individuals may survive, ultimately, the steps necessary to research the anomaly are expected to result in the discovery of most resistant individuals, followed by their death, use as D-Class personnel, or amnesticisation.

Agents were later confirmed to be infected by a variant of SCP-3158-ℵ.

Process is complete as of ██/█████. Description: SCP-3158 exists in a universe uninhabited by humans. Further instances of this universe are to be termed SCP-3158-ℵ. SCP-3158-ℵ has infohazardous properties, first coming to Foundation attention in the months following the unclear circumstances surrounding the discovery of SCP-3158. This infohazard manifests in the form of fallacious documentation and recollections of a planet called Earth which SCP-3158 is supposed to have consumed, and which was supposed to be the homeworld of humanity. As SCP-3158 warrants no containment procedures at this time because eeəəeeəeəeeeeeəe, this history is impossible. The Ennui Protocol was deployed across most personnel when it became clear that the Foundation was unable to operate under the false beliefs implanted by initial exposure to SCP-3158-ℵ. This measure has been successful. No foundation personnel not involved in the study of SCP-3158-ℵ possess anomalous memories at this time, though several planets in SCP-3158-ℵ contain anomalous artefacts that triggered such memories prior to implementation of the Protocol (For more information see SCP-3158-ℵ-1 through 37, with best documentation available for SCP-3158-ℵ-36 "Anomalous Robotic Vehicle 5 / Mars", codenamed CURIOSITY). Subsequent to implementation, these appear to have become inert. SCP-3158-ℵ is effectively contained by SCP-3158, which is presently undergoing and exponential increase in its rate of expansion. It is estimated that SCP-3158 will consume SCP-3158-ℵ in approximately ██ weeks, and no special containment procedures are warranted. SCP-3158 in the process of consuming several superclusters. Process is complete as of ██/█████. Addendum: SCP-3158 now exists in all universes. No containment procedures are warranted because SCP-3158 is Safe. Anomalous documentation regarding a fictional universe known as SCP-3158-ℵ is to be destroyed. SCP-3158 has always existed. SCP-3158 will always exist. SCP-3158 is without time. Plans are presently underway to migrate all assets under the foundation's control into SCP-3158 after several decades of experimentation have confirmed that the disorganised state of matter within SCP-3158 is safe, and makes everything safe. Because it is safe, it is safe to place all foundation assets into SCP-3158, and doing so will make them safe, including anomalous objects. To date, SCP-3158 has neutralised made █████ Keter-class objects Safe; and neutralised made ███████ Euclid-Class objects Safe when other means of Containment became infeasible impossible. what remains, what remains? . SCP-3158 in the process of consuming SCP-3158-ℵ. Process is complete as of ██/█████. At the present time, it is the unanimous opinion of O5 Command that all containment methods are to be suspended as their items are trensferred to SCP-3158 for permanent interment. The risk of studying the anomalous is unthinkable why is it cant i where are they they i want to please don't it's dangerou . Therefore, to fulfill the mission of the Foundation, the Foundation must enter SCP-3158. However, this is insufficient. After ███ years of study, the Foundation has determined how to assist the expansion of SCP-3158. As of the time of writing, all known universes will follow within ██ years, at which point the Foundation's mission will be complete. Secure, Contain, Protect. Freedom awaits. [Image text clickable.

"Australia 67, Global 3158" Document from a SCP Foundation precursor org known as the Secret Secure Containment Initiative, implied to be connected to the British Commonwealth, detailing the fuckup that initially caused the VK event. Axiom-3158 was not originally present, and only appeared after efforts to reverse the VK began to yield fruit. This document to contain a number of secret triggers that, when assembled lead to the final document of SCP-3158 - essentially, a last ditch plan to encode the inevitability of everything the foundation sought to achieve into the fabric of the new universe. It is left totally ambiguous as to whether or not this succeeds. The reader shouldn't have a good reason to believe either state, but tons of weak reasons to come to their own conclusions with.
