Item #: SCP-XXXX
Object Class: Safe.
Special Containment Procedures:
For conservation purposes, SCP-XXXX is to be stored in a containment chamber with temperature held at 15 ºC and relative air humidity between 30% and 35%. The containment chamber should be equipped with incendiary charges.
The object must be cleaned of dust at least once year, and it must only be handled by personnel wearing acid-free rubber gloves and breathing masks in a mild light environment. When not being cleaned, SCP-XXXX must be stored within an opaque polyethylene bag, which is to be itself stored in a padded metal box of tight fit, remaining in the chamber at all times. Eventual repairs or restorations of the item are to be deferred to archival specialists ─ should the physical integrity of the item become threatened, its contents should be digitalized and copies kept in isolated computers.
As of the moment of writing, no experiments are allowed to be carried out with SCP-XXXX, by decision of the O5 council. Evidence of attempted experiments will be investigated and the responsible personnel will be judged by a special jury of the Ethics Committee members.
Additionally, no sentient entities are allowed to read the contents of SCP-XXXX, if censorship of SCP-XXXX is threatened, the chamber's incendiary charges must be detonated without hesitation.
Description:
SCP-XXXX is a hardcover book in B5 paper. The leather bound codex is bears its title on the face and spine of the book: “Ex Falso, Ad Falso” in a font that resembles the Garamond family, but the particular specimen could not be determined. The contents of “Ex Falso, Ad Falso” are not fully known, the preface and samples of pages suggest that the book is a mathematical text that seeks to prove its own nonexistent. The author's name could not be found.
The object was initially recovered by [DATA LOST], in an abandoned room of the Massachusetts Institute of Technology during her visit of an old colleague which supposedly held a chair in the institution in 19██. Since then, no researchers have been assigned to the research of its effects. The book was recovered due to [DATA LOST]'s [DATA LOST].
The book's effects are not fully understood, Dr. [DATA LOST], Dr [DATA LOST], [DATA LOST] and [DATA LOST] suggest that subjects that read sufficient portions of SCP-XXXX [DATA LOST], or several adverse effects ─ although no proof of causality could be established. Incidents include a senior researcher's heart attack, a containment breach with unknown causes in a different facility, [REDACTED] and [EXPUNGED].
Meta-analysis of the lack of experiments on the book suggests that the book doesn't exists, as it hasn't been read ─ to the best of our knowledge. [DATA LOST] suggested that having someone read it within the sphere of influence of a Scranton Reality Anchor might alleviate [DATA LOST]. No tests of that hypothesis have been found. All current knowledge of
this object has been compiled by Researcher Hobbes. in an effort to develop counter measures for metaphysically destructive objects. See Addendum SCP-XXXX.1 for a detailed account of his successful experiments.
As of Dr. H.'s suggestion's to the O5 council, no more experiments are to be carried out, as statistical analysis found correlation of attempted experiments and negative events to Foundation assets.
Addendum SCP-XXXX.1: Dr. Hobbes' Research Notes
Test 00
Procedure: Meta Analysis of Data Corruption surrounding SCP-XXXX
Results: People supposedly involved directly with SCP-XXXX have never existed, their names have been lost and most data pertaining to their supposed interactions has been corrupted. Personnel indirectly responsible for attempted tests, be it the researchers that ordered tests, guards that were scheduled to supervise D class test subjects during reading, etc. were affected by negative natural events 98.3% of the times when the assigned test subject failed to read SCP-XXXX but were found to still exist.
The most serious instances of negative events have been the the breach of ██/██/1███ of site ██, the [REDACTED] of Dr. ██████ █. and Agent ████'s [DATA EXPUNGED]. Associated negative events with attempted readings of SCP-XXXX are related to the object's inability of preventing them ─ we have 8σ certainty of SCP-XXXX being casually related to the negative effects. See Analysis for a more detailed account of how experiments may lead to global negative effects.
Analysis: Directly reading SCP-XXXX seems to be impossible, in the sense that anyone attempting to do so, will, inadvertently, cease to exist. The non-existence appears to be retroactive, leaving only circumstantial evidence of their presence. If reality restructuring is impossible and the reader cannot be expunged, SCP-XXXX will affect the agents in the causal chain that lead to the reading in the first place. Effects are strongest on people directly responsible for the experiment, and appear to diminish as their involvement becomes more indirect. Effects are indistinguishable from chance at 4 levels of separation.
Dr. “[DATA LOST]”'s proposal of having someone read the document within range of a Scranton Anchor was a clever idea, but due to their close causal connection to the experiment, and the fact that they weren't near an anchor themselves, the experiment ─ that never happened ─ probably expunged them from reality.
Other destructive effects of attempted readings seem to target specific people or infrastructure. The Breach Incident killed all D class personnel assigned to SCP-XXXX testing before they were transferred to this facility. Agent ████'s [DATA EXPUNGED] lead to a change of protocol that prevented a series of tests ordered by Dr. ██████ █. then assigned to SCP-XXXX. Her [REDACTED] further prevented those tests from being performed. The designed tests had all relevant personnel near reality anchors of one sort of another ─ Namely, Scranton designs Mk IV and VII.
Test 01: Metaphysical Red Tape
Subject: SCP-XXXX, 50 D class personnel.
Procedure: 49 D class personnel were chosen for good behavior, they were arranged in 7 groups of 7 members each. Each group received a role in a intentionally overly complex system of bureaus and red tape and were tasked with designing, discussing, approving, vetoing, organizing and guarding tests with SCP-XXXX. They were were given a list of resources they had available to them, which included a Scranton Anchor. The remaining D class were provided for the designed tests. The subjects were given mostly free range, but were supervised by guards ─ who were secretly ordered not to interfere ─ and were told their behavior would determine their next assignment, and reminded of the more unpleasant places they could be.
Results: After 4 months of test design, none of which were executed ─ presumably because the test subjects never existed ─, the inmates designed an experiment similar Dr. “[DATA LOST]”'s proposal. It took 8 days to be designed, almost 10x the time it took to design any other test. After it was designed, 6 of the inmates in the ethics and discussion bureaus were unable to perform their roles due to illness for an entire week. After the test passed those bureaus, all of the inmates responsible for approving tests were diagnosed with severe depression and spent days under medication before resuming their activities; a riot broke out in the vetoing department and all progress was halted after a key inmate in the organizing department committed suicide. The test was subsequently called off, as enough information had been obtained and the consequences were judged to have escalated too much.
Analysis: It has become obvious that SCP-XXXX can change reality globally, and its effects grow in intensity as agents become causally closer to an attempt to read SCP-XXXX. If at all possible, SCP-XXXX simply removes the reader, when reality restructuring is impossible, it alters all responsible parties. Further testing is necessary to show if it is the case, but the number of people causally related may also affect intensity. Performing the same test with bigger and smaller bureaus should answer this question.
As advised by Site Director, Test 02 was carried out much more aggressively, to better assess the actual potential of SCP-XXXX.
Test 02: Metaphysical Red Tape ─ Cont.
Subject: SCP-XXXX, 26 D class personnel.
Procedure: Personnel were not selected with any trait in mind this time. They were similarly divided in 5 groups of 5, told to design tests. Exactly the same setup of Test 01.
Results: After weeks of testing, the inmates designed a test that would make SCP-XXXX removing the test subject from existence unfeasible. Increasingly negative ─ much more so than in the previous test ─ events began happening to the inmates, until Dr. Hobbes. suffered a car crash and immediately called off the experiment.
Analysis: Okay, let's stop the testing. It seems the order SCP-XXXX in which affects agents does not respect their causal closeness to the test, but an event's intensity is correlated to the number of people more causally connected to the test. Having about half as many people related to the test seems to make it dangerous for people with 6 degrees of separation to any reading attempts.
Addendum SCP-XXXX.2: Dr. Hobbes' Potential Threat Assessment of SCP-XXXX
I strongly advise against testing SCP-XXXX, period. But if tests must be made, my suggestion is to avoid testing with Reality Anchors or Reality Benders, since this may amplify SCP-XXXX's destructive nature, in the case of Anchors or shape and alter its reality restructuring properties. It is unclear what are the potential consequences of such tests. Best case is they are removed from reality, worst case is a ⊥K-Class End of Mathematics Event: the propagation of “Ex Falso, Ad Falso”'s contradictory nature to the rest of mathematics and the complete overturning of our metaphysics.
Dr. Hobbes has requested to be transferred to another site after presenting his findings.
