 Item No. SCP-2161 Object Class, Euclid Special Containment Procedures SCP-2161-1 is to be contained in a warehouse, 10,000 cubic meters minimum, and its rate of increase in volume monitored. Paper products are prohibited in the warehouse's vicinity. Electronic scanning and analysis of existing pages is to continue. SCP-2161-2 is confined to a limited set of Foundation files, including this document on a secure server, with study continuing into its nature. Any document containing SCP-2161-2 must not be printed nor attached to a non-secure file. Description SCP-2161-1 is a collection of approximately 85 million pages of self-replicating A4 paper, the majority of which are blank. A small proportion of pages contain letters, figures, or other markings, suggesting an SCP-2161-1 originally formed a single text. As of 1 July 2015, SCP-2161-1 spontaneously generates blank paper at a rate of approximately two pages per hour, several orders of magnitude slower than when first contained. These or similar paper products brought into contact with SCP-2161-1 become subject to the same effect, their volume increasing through the generation of blank space, with any original text eventually spread across thousands of pages. SCP-2161-1 was discovered at the former Adelaide home of Dr. Harper, Australian physicist and author, after neighbors complained of an abandoned house surrounded by large amounts of litter. In-contacts were alerted when government refuge workers reported the anomalous increase in paper volume. SCP-2161-2 is a computer virus, which increases the amount of white space in electronic documents in a manner similar to SCP-2161-1. Any file to which an SCP-2161-2 infected document is attached will itself become infected, but the infection is not evident in underlying code, suggesting an anomalous source. SCP-2161-2 was detected through the Foundation's scanning of SCP-2161-1 pages, and the inclusion of a photographic image in this document. Addendum SCP-2161-A Interim Scanning Results 5% Complete Algorithmic recombination of scanned pages containing text or other marks suggests that SCP-2161-1 was originally technical documentation involving complex mathematics. 10% Complete Scanning now indicates calculations and schematics for a faster-than-light interstellar vessel. The mechanics of travel are unclear, but textual fragments imply that the blank space generated in SCP-2161-1 and SCP-2161-2 may be an exhaust byproduct of the craft's propulsion system. Dr. Harper, the presumed author, is to be sought for questioning. Addendum SCP-2161-B Addendum SCP-2161-B On July 24, 2015, cameras in SCP-2161-1's storage warehouse detected text appearing on new pages generated by SCP-2161-1. The text was collected and has been compiled as follows. I have traveled to the edge, watched it expand into nothingness. I have found no one, no other earth. I shall search on.
