SCP-3958: Little Brother 


Item #: SCP-3958 
Object Class: Euclid 


Special Containment Procedures: SCP-3958 is currently not 
contained. Any civilian air-transport is to be delayed to keep planes 
out of its flight-path. Additionally, several smaller communities in the 
Democratic Republic of the Congo, Tanzania, Gabon and have 
been relocated to minimize the chances of exposure or lethal injury. 
Contact with living creatures is to be avoided at all times. Slabs of 
soil of at least 200 kg are placed at a height of at least 20 meters or 
highest point of construction in high-density population centers to 
reduce risk of collision. 


Description: SCP-3958 is a miniature replica of planet Earth, 
approximately 38 mm in diameter. SCP-3958 is spatially locked 
above the ground with respect to the Sun, such that it always 
remains on the night side of the Earth underneath the L2 Lagrange 
point. To maintain this spatial orientation, SCP-3958 moves at a 
speed of 1656 kph relative to a terrestrial observer, and hovers at 
altitudes between 1.5 and 2860 meters above sea level.! 


Regardless of its height, SCP-3958 will never come within 1.5 
meters of terrain (defined here as untreated soil with a mass of at 
least 150 kg). 


No methods of arresting SCP-3958's movement have been found; it 
invariably penetrates all inanimate materials that it contacts without 
losing speed. Further testing on inorganic matter has been 
suspended after the impact with caused rapid heating and 
expansion, resulting in the injury of Foundation personnel. Any living 
organic being possessing a mass of 25 kg or higher that comes into 
contact with SCP-3958 will gain its anomalous properties until 
contact is broken. This has so far universally resulted in the 
subject's expiration due to rapid deceleration and impact with the 


environment. 


Addendum: SCP-3958 Discovery Log SCP-3958 came to the 
attention of the SCP Foundation at [REDACTED] on Oct , 1962. 
Due to Foundation resources invested in the and 
governments, damage done by SCP-3958 to the ships ‘ and 

was quickly reported to the Foundation. Damage was 
explained to both parties by Foundation personnel as ammunition 
malfunctions. 


Further analysis of the event and reconstruction of path of damage 
resulted in the calculation of SCP-3958's trajectory and its next 
position was successfully predicted and caught on satellite image. 


Three research stations were established in the South China Sea 
and the Indian Ocean, to record SCP-3958's momentum and 
anomalous properties. At the time, these were the only three 
instances of SCP-3958 moving close enough to non-populated 
areas for testing. 


+ Addendum: Test Log A - Date: / /1966 


Test conducted at research station Digit Beta 
in the South China sea. 


Tests equipment: 


* Two panels of rice paper, ten meters 
apart, for soeed measurements. 

* Three panes of solid steel, thickness of 

ten cm, one meter and three meters. 

One block of soil, fifty cm thick, encased 

in glass of five cm thickness. 

¢ Five 35 mm rotating prism cameras. 


SCP-3958 was correctly projected to arrive at 
0254 HKT at an altitude of 12 meters. 
Measurements made of the object upon 
perforation of paper testing sheets indicate a 
speed upwards of 1500 kilometers per hour. 


Recovered camera footage shows that 
SCP-3958 showed no visible signs of slowing 
down upon contact with the steel panes. The 
rapid displacement of the steel plates caused 
the destruction of the block of soil and injured 
two Foundation researchers. 


Testing on solid matter with tensile strength 
exceeding 150 MPa is prohibited until further 
notice. 


+ Addendum: Test Log B - Date: / /1969 


Test conducted at research station Dharatee 2 
in the Bay of Bengal. 


Test equipment: 


¢ Two panels of rice paper, ten meters 
apart, for soeed measurements. 

* One block of soil, fifty cm thick, encased 
in glass of five cm thickness. 

* One Osmanabadi Goat. 

¢ Ten 70 mm rotating prism cameras. 


SCP-3958 was projected to arrive at 0110 IST 
at an altitude of 45 meters. Cameras angled to 
view the approach of SCP-3958 recorded it to 
change velocity at a 90-degree angle at an 
estimated 45-50 meters distance away from 
the block of soil. It then proceeded to move in 
an arc above the soil, then resuming its course 
on the other side. 


Due to failure to achieve impact with goat, 
testing D-class was approved. 


+ Addendum: Test Log C - Date: / /1971 


Test conducted at research station Tierra 
Segundo in the Gulf of Mexico. 


Test equipment: 


* Two panels of paper, ten meters apart, 
for speed measurements. 

¢ One D-class Test subject 

* Twenty-five Experimental Photec 16mm 
Cameras. 


SCP-3958 was projected to arrive at 0319 
CDT at an altitude of 72 meters. Velocity of 
SCP-3958 was recorded at 1656 kph. 


Upon contact with D-654167, SCP-3958's 
secondary anomalous property was 
discovered. Camera footage shows D-654167 
accelerating along with SCP-3958 
instantaneously upon contact. Equipment 
attached to the subject shows normal vital 
signs with elevated heart rate for several 
seconds after impact with SCP-3958, at which 
point D-654167 broke contact with SCP-3958 
and ceased exhibiting anomalous properties. 
The point of impact was discovered near 
Monterrey, Mexico. No remains could be 
recovered. 


Included below are recovered documents that indicate previous 
encounters with SCP-3958. 


+ Addendum: Recovered Document VO-1 


VO-1 is a collection of notes taken by ; 
Durango, Mexico. They detail a series of 
experiments and observations of an 
unidentified object moving at high speeds. 


The two mills, built as scheduled, are 
exactly five-hundred miles apart. My 
assistants are to take note of the 
speed of the sphere as best they can. 
More importantly, they will have time- 


telling devices on their persons. 
Hopefully, measuring the time 
between the two observations will 
give me an approximation of the 
actual speed of the object. 


The observations are as accurate as 

| could hope them to be. My 
assistants were not acquainted well 
with their time-telling devices, and the 
conclusion offered by my data is not 
satisfactory. No object present on 
earth can move a hundreds of miles 
in a matter of minutes. 


There is a period of several years where no 
pages were written on this subject. The final 
page, an autobiographical memoir, includes 
this paragraph: 


| went back to the mills, and tried, 
again, to measure the sphere's 
speed. Additional tests keep verifying 
the old data. This is not acceptable. 
My country has enough trouble as it 
is to be dealing with impossible 
objects. Regardless, for posterity, | 
have included my data. 


No further pages were found 
+ Addendum: Recovered Document TE-2 


TE-2 is a series of engravings recovered in the 
valley of Mexico. It appears to predate late- 
Mexica culture. 


The priest spoke of a sign of the 
gods. At the moon's zenith, the sign 
came down. Mixcoatl passed through 
the heavens, carrying his bounty and 


his dictate. With a scream his bounty 
was spread onto the steps and 
showered all beholden in blood. The 
priest knew then what was to 
happen. Once at day and once at 
night, blood would be spilled in the 
name of Tezcatlipoca and Mixcoatl. 


+ Addendum: Recovered Document CA-3 


CA-3 is a stone tablet found in an 


antechamber of the . Its hieroglyphics 


indicate its age to be around 4500 to 4600 
years old. 


Ahmes is a fool or a madman. The tip 
of the monument collapsed overnight, 
but he claims it was struck down by a 
divine force. He is an incompetent 
overseer, and will be replaced. This 
does give me the opportunity to build 
the golden cover | had intended as 
first planned. The living god will be 
pleased. If it was divine force, it 
means me well. 


+ Addendum: Recovered Document BR-4 


BR-2 is a series of religious text from the 
region in India. They detail the life of a guru 
from between the 1st and 2nd century BC, 


who proselytizes the existence of a deity who 


flies over the land at night, and can only be 
observed in winter. 


His life's story is that like of a lot of gurus, until 


his 54th year. 


Guru ascended the temple on 
the first day of Magha at dawn. He 
meditated during the day, preparing 
himself for the arrival of Parameshvar 


. Then, after sundown, he 
chanted as he anticipated the divine. 
After the darkest hour of night, we all 
felt the presence of the deity. Then in 
an act of god, the Guru was taken 
from the top of the temple. 
Parameshvar swooped down 
and carried the Guru with him with an 
earth-shattering thunder. The roof of 
the temple exploded. The Guru 
screamed with elation, and we know 


Parameshvar helped him 
ascend. 
It must be noted that Guru 's teachings 


are abolished in India. 
+ Addendum: Recovered Document NT-5 


NT-1 are the designs to a machine, as 
designed by , recovered from a town in 
Krasnoyarsk Krai. 


The designs describe a theoretical construct, 1 
kilometer long, that would use internal, highly 
pliable dynamos that would output an 
astronomical amount of energy, to be stored in 
a system of batteries not otherwise referenced 
in the notes. 


Of important note is the generator's design, 
which has been designed to the dimensions of 
SCP-3958. This is further substantiated by 
several drawings of a sphere with SCP-3958's 
exact specifications. 


In my study of non-typical, non- 
physical phenomena, | have 
discovered an object of theoretically 
infinite power. This will let me make 
more progress in one day than all the 


previous decades combined. 


The reason NT-1 is of such note is its location, 
which is outside of the range of SCP-3958's 
motion, implying the existence of another 
instance of SCP-3958. 


Footnotes 

1. The changes in SCP-3958's altitude are directly proportional to 
the distance between Earth's Perihelion and Aphelion. SCP-3958 is 
closest to the Earth's surface when the Earth is at Perihelion, in 
January, and furthest at Aphelion, in July. 


Local emergency services had been summoned to evacuate the 
area due to reports of unusual lightning strikes. SCP-512 was 
discovered caught on a streetlamp and fully opened, with evidence 
of several lightning strikes in the immediate area. Its handle was 
noted to be covered in ash. Foundation personnel intervened after 
local newspapers began reporting on SCP-512's anomalous 
properties. 


Addendum: Testing Summary 


Upon recovery SCP-512 underwent standard testing, through which 
its properties were determined. A range of items were held 4 meters 
above SCP-512 and then dropped, after which a mechanical 
apparatus would open SCP-512. 


Tested items include the following: 


* 1 liter of purified water, dumped from a standard bucket 

¢ 1 liter of orange juice from concentrate 

* approximately 1 kilogram of loose feathers 

* 1 kilogram of ice cubes 

¢ The assorted contents of Junior Researcher Renfield's 
bagged lunch 

¢ A standard running shoe 

¢ A standard watermelon 

* SCP-1108 

* A5.4-kilogram bowling ball 

* A 40-kilogram steel containment crate 


Testing materials slowed in descent approximately .5 seconds after 
SCP-512 opened, with the larger and less solid items coming to a 
stop approximately .35 meters from SCP-512's surface. All material 
will remain suspended in the air, unless made to slide to one side 
and resume freefall. Liquids and particulate matter are weakly 
repelled from the center of the effect, while more solid objects can 
be held in place with minor adjustments to SCP-512's angle. 


Addendum: Experiment D-512-33 


Testing Item: D-Class personnel 


SCP-3959: The End of All Knowledge 


James, 


That terminal in 362, sublevel 6 is still locked. Why we 
even have an unregistered personal computer in 01 is 
beyond me, and it needs to be addressed. 


Seriously though, get someone from IT down here and 
take care of it. We are the largest data reliquary for the 
entire Foundation. We don't need anything to go wrong 
here. 


Fix it. 
Site Director A. Phillips 
Audrey, 


Sent one of the techs down there the other day, said the 
computer was locked with level 5 multifactor 
authentication. 


What the hell is it doing down there? If the data on there 
is so highly sensitive, no one would have just signed off 
on leaving where it was. | honestly would have just 
tossed the thing. 


Just keep it running for now. It isn't hurting anyone. 
Sr. Researcher J. Harkness 
Audrey, 


Went poking around on the device's hard drive. Most of it 
is heavily encrypted, but | managed to find a few files. 


| found some documentation for a SCP-3959, looks 
dated. Timestamp says it's around seven years old. 
Hadn't been accessed in five. Next time you are free, 
cross reference these files with the ones stored on our 
backup just to be safe.

Item #: SCP-3959 
Object Class: Euclid 


Special Containment Procedures: Members 
of Mobile Task Force Kappa-10 ("Skynet") are 
assigned the task of tracking SCP-3959. All 
personnel assigned to the study of SCP-3959 
must score above a 40 on the Anomalous 
Cognition Resistance Scale (See Addendum 
3959-1-1A). 


Due to the nature of the anomaly, containment 
is nearly impossible, albeit unnecessary, as 
SCP-3959 tends to locate itself within close 
vicinity of Foundation servers, specifically 
those of Site-01, the facility responsible for the 
backup of all archived data. Despite this, 
effective means of containing SCP-3959 
should be implemented as soon as possible 


At no time should material affected by 
SCP-3959 make contact with any sensitive 
data or media that might help facilitate an 
external breach of Foundation property. 


All backup data at Site-01 must be checked for 


inconsistencies daily by a group of assigned 
individuals with level 5 clearance. 


Description: SCP-3959 is the designation for 
an autonomous cognitohazard that can exist 
within any form of communication medium. It 
has been shown to occupy a wide variety of 
objects, such as a website, a desktop placard 
and a radio broadcast (See Experiment Log 
3959-1-1A for more information). 


SCP-3959 is presumed to have infovorous 
tendencies, and therefore gravitates towards 
large amounts of data, particularly non-fiction 
works. SCP-3959 is capable of transferring 
itself onto any media directly facing or in 
contact with the current host?. When 
SCP-3959 finds a suitable host medium, it will 
transfer itself, regardless of distance. 


Any media that is currently in contact with 
SCP-3959 will start to automatically redact its 
own information over a period of time that is 
directly proportional to its own complexity. 
Most information is obscured by standard full- 
block Unicode, although other methods have 
been recorded. This is considered SCP-3959 
"feeding". If left undeterred, SCP-3959 will not 
stop this process until all information present is 
obscured and irretrievable. 


SCP-3959 shows remarkable intelligence and 
has been able to access digital software with 
relative ease, bypassing many security 
restrictions and potentially compromising 
sections of Site-01's databases.
