The influence of the gravitation of thousands of objects acts as a 
strange attractor, keeping each individual object within 105 m of the 
center of SCP-2460 at all times. The chaotic nature of the attractor 
has caused multiple objects to be shown at the surface of SCP-2460 
at different intervals. Most of the items expressed are space dust 
and rocky debris similar in composition to asteroids. The following 
items are notable, however: 


¢ A planetesimal with the above dimensions of 50m x 30m x 
15m. This item acts as the "surface" of SCP-2460. Of note is 
the distinct lack of cratering on the surface. 

¢« Acomet nucleus of approximately 5m diameter. Visible 

spectral analysis suggests that the object's original location 

was the Oort cloud. 

A spacefaring vessel of unknown make, 10m in length. The 

hull is covered with unidentified symbols. Through a plate 

glass window, two beings are visible, apparently long 
deceased and dessicated, resembling crocodilian humanoids. 


¢ Approximately 1,000 metric tons of hydrogen and helium, 
compressed under gravitation into a superfluid state. 

« Ninety capsules, each containing a single humanoid occupant, 
each colocating independently from the others. The occupants 
are apparently dead and dessicated. 

¢ Foundation Probe OU11-3 and Agent Rick Roberts, 
deceased. (See Addendum 2460-B) 


Addendum 2460-A: On 2/15/2013, a stray orbiting steel bolt 
attached to a retaining plate from the [REDACTED] disaster was 
seen to be captured by the gravity well and collide with SCP-2460. It 
was observed that the collision caused no impact site and the bolt 
passed through the matter without hindrance. However, post 
collision the bolt and plate no longer registered any electromagnetic 
field deformation. Further observation demonstrated that the bolt 
remains attached to the plate, confirming that the colocation effect of 
items caught within the anomaly does not extend to items that are 
exposed within milliseconds to it. 


This observation further suggests that all objects seen in SCP-2460 
were, at one time, normal fermionic matter, transformed by the 
anomaly into the presently seen amalgamation. It is hypothesized 
that the anomaly annihilates the quantum spin of the subatomic 
particles, transforming the matter from fermionic to bosonic and 
allowing it to colocate. Containment procedures updated to prevent 
further matter collisions with SCP-2460. Further testing is 
suggested. 


Addendum 2460-B: On 2/5/2014, SCP-2460 was noted to pass 
within 70 km of Foundation Orbital Unit-11, and a sortie was 
authorized to intercept the anomaly for quantum measurements. 
Agent Rick Roberts was sent in Probe OU11-3 to examine the 
anomaly at close range for testing of the quantum signature of the 
matter within the object. Radio contact with Probe OU11-3 ceased 
when the probe came within 5 km of the central mass. 
Approximately 0.5 seconds before loss of contact, apparent density 
of the low Earth orbit medium seen to increase from 1.0 x 10°11 kg/ 
m3 to 7.3 x 10°9 kg/m. 


All remaining data from the experiment comes from the cameras 
aboard Orbital Unit-11. Agent Roberts quickly noted the lack of radio 


contact, and engaged thrusters to maneuver away from SCP-2460. 
The fuel was seen to ignite and pass ineffectually through the hull 
and cabin of Probe OU11-3. Unable to adjust position or trajectory, 
Probe OU11-3 was gravitationally captured by SCP-2460 and fell 
into the central mass. 


15,534 kg added to the mass of SCP-2460. Trajectory and 
Schwarzschild radius recalculated. Containment procedures 
updated to include a mandatory distance of 50 km. 


Addendum 2460-C: Transcript of lecture regarding SCP-2460 on 
4/3/2015 


Presenter: Dr. Cordelia Argent, Principal Researcher, 
Astronomical Phenomena Division 


Foreword: Dr. C. Argent presents the results of her 
observations and experiments with SCP-2460. 


<Begin Log> 


Dr. C. Argent: Good evening and welcome. | want to 
thank everyone for coming this evening. Tonight, | am 
going to explain what, exactly, SCP-2460 is, and the risk 
it represents for the Earth. 


| could explain the fermion-to-boson conversion called 
quantum spin annihilation, explain how this interaction is 
possible under a version of supersymmetry, the 
transformation of quarks to squarks and so on. But I'm 
sure that that would go over most of your heads. You 
could learn it all, but you're here to understand what this 
is and what it means. I'll spare you the physics. 


I'm sure you've heard stories of walking through walls. 
Ghosts, radio waves, certain anomalies, et cetera. 
Phasing is a popular term for it. In essence, SCP-2460 is 
a collection of objects - asteroids, comets, nebula 
material, stellar mass, and more - all phasing through 
each other. It's important to recognize that this phasing is 
the sole reason all these objects exist in the same place 


at the same time. This is not a spatiotemporal distortion, 
at least, not anything more than is fully and non- 
anomalously explainable via its gravity alone. 


However, what is less explainable is the lack of 
electromagnetic interaction within SCP-2460. Firstly, this 
means that there is no radio communication possible 
with anything within the anomaly. Radio waves pass 
through it as if it wasn't there. This is also what leads to 
the phasing effect we see. You know how we are made 
of atoms, and atoms consist of a nucleus surrounded by 
an electron cloud? These electron clouds are negatively 
charged and push each other away, and that's why we 
can't walk through walls. But within SCP-2460, the 
electron fields between objects introduced at separate 
times don't interact, don't push against each other, and 
as a result, don't stop objects from passing through one 
another. 


But wait, you're probably asking, isn't the photon the 
gauge boson for the electromagnetic interaction? Why 
do we see anything? Okay, you're likely not asking that, 
but | did, first thing. The truth is, we don't see most of 
SCP-2460. Experiment 2460-B proved that. We saw the 
medium density around Probe OU11-3 increase nearly a 
thousandfold before losing contact. There is a cloud of 
massive particles that have nearly no interaction with 
normal matter extending as far as 5 km from the central 
mass. There are only two ways these particles interact: 
gravitationally, and rendering normal matter that comes 
in contact with it out of phase. These particles are 
invisible and otherwise undetectable. All remaining mass 
was added subsequently, acting as an anchor for the 
particles. That's why we can see the massive objects in 
the center. 


What's the risk from this? Well, it is exceptionally dense, 
and thus perturbations from its present orbit will 
preferentially cause the orbit to decay, resulting in 
SCP-2460 falling to the Earth. Now, since it remains 


"phased out," collision with the Earth won't cause any 
impact crater. However, the quantum spin annihilation 
will affect all matter the anomaly passes through, 
resulting in invisible holes of phased out ground. 
SCP-2460 will pass unhindered through the center of the 
Earth, transforming matter the entire way, leaving a giant 
hole through the center of the Earth that the liquid mantle 
and core will gush into, the crust and surface eventually 
falling, unsupported, into the hole. But it won't end there. 
The momentum in SCP-2460 will propel it all the way 
back out of the center of the earth, back to the surface, 
where it will gravitationally oscillate back and forth, back 
and forth, rendering more and more of the Earth out of 
phase with itself like Swiss cheese until the entire planet 
collapses into a central superdense pile of untouchable 
rubble, constituting a QK-Class Quantum Degeneracy 
End-Of-The-World scenario. 


So I'm sure you agree that we want this thing as far away 
from us as possible. The problem is, we can't touch it. 
We can't use thrusters to push it away. There's nothing 
to push against. We can't deflect it with magnetic fields. 
There's no electromagnetic interaction. We can only use 
gravity to pull it away. That means that we will need to 
tow an asteroid of similar mass into Low Earth Orbit to 
carefully slingshot the anomaly away from us, then 
destroy the asteroid somehow. An asteroid 
approximately 22 km in diameter should contain enough 
mass to eject the anomaly. Recommendations have 
been submitted to O5 Command. 


But I'm sure you actually are all asking, what is this, and 
why did it end up here, orbiting around the Earth? Well, it 
is an amalgamation of weakly interacting massive 
particles, invisible to electromagnetic radiation, emitting 
no radiation of its own, and possessing only gravity. 


In short, ladies and gentlemen, SCP-2460 is dark matter. 


And when you consider that fully 85% of the mass in the 
universe is dark matter, we should not ask why we are 


so unlucky to have a chunk of it orbiting around the 
Earth. We should ask why we are so lucky that we 
haven't hit any of this stuff yet. 


Thank you, and good evening.

SCP-2461: Aftermath 


Item #: SCP-2461 
Object Class: Safe 


Special Containment Procedures: Following the accidental deaths 
of Dr. and the remainder of the SCP-2461 research team, no 
further research into SCP-2461 is to be carried out without a 
unanimous consent of the O5 council. The remaining SCP-2461 
artifacts are to be placed in High Security Containment at Armed 
Containment Site 2461. No access to SCP-2461 is to be permitted 
without unanimous consent of the O5 council. Anti-theft measures in 
place at Armed Containment Site 2461 are classified under Protocol 
999-2461-Gernsback. Lethal force is authorized to prevent theft of 
SCP-2461 objects. 


Description: SCP-2461 is a series of artifacts recovered from a 
crash siteon - - 


SCP-2461-A: A disc-shaped device approximately 45 meters in 
diameter and 10.5 meters in height. Device's exterior is covered ina 
radar-absorbing material. Entrance and egress are possible through 
a dilating iris doorway in the central underside of the device, either 
by ladder, elevator, or roof-mounted gravity lift. 


The interior of the device is divided into three levels, each 
approximately 3 meters in interior height. The topmost level (Deck 1) 
appears to be devoted to command and control, and includes a 
control center, observation dome, and navigation systems. The 
second level appears to be devoted to engineering and avionics, 
and includes the avionics, engine, and flight control systems. A 
small living quarters, including galley and cots, is also located on 
this level. The third level contains the remaining avionics and flight 
control systems, but is mostly made up of a toroidal fuel tank, 


272-f 

Test subject: 2 D-Class (D-272-04 and D-272-05) 
Surface: As above 

Lighting: 2 stadium lights, positioned 90° apart 
Purpose: Determine if multiple subjects can be held. 
Procedure: Subjects positioned so their shadows 
overlap. Object dropped onto both shadows. Subjects 
told to advance away from the nail. 

Results: Object embeds. Subject D-272-04 continues 
unhindered, but reports feeling a ‘chill’. D-272-05 is held 
by the object. Object recovered. 

Conclusions: Object cannot hold more than one 
subject. Potential secondary effect observed. 


272-g 

Test subject: 8 D-Class (D-272-04 - D-272-11) - See 
addendum for details 

Surface: As above 

Lighting: 4 stadium lights, positioned in a ring around 
the subjects 

Purpose: Determine the selection mechanism for which 
subject is held. 

Procedure: Subjects positioned so their shadows 
overlap. Nail dropped onto all 8 shadows. 

Results: Object embeds. Subject D-272-09 is held (18 
YOA, Caucasian, 1.8 m, 88 kg), all others free to move. 
Reports of a scream from all subjects except D-272-09. 
All subjects except D-272-09 seen to shiver. Object 
recovered. D-272-09 removed from study, experiment 
repeated. Subject D-272-06 held (24 YOA, Hispanic, 
1.6 m, 102 kg), all others appear to shiver and report a 
scream but remain free. Experiment repeated four 
additional times as per the above method; discontinued 
after D-272-07 fell unconscious. Subject given treatment 
for severe hypothermia. 

Conclusions: Emerging patterns suggest that the 
youngest possible subject to be held will be. Additionally, 
secondary effect on larger groups observed; further 
research pending acquisition of a larger sample group. 


containing approximately 40,000 liters of an unknown combustible 
liquid. At the moment of the writing of this article, 10,000 liters of fuel 
remain in the tank. 


The underside of the device has six hemispherical protrusions 
located at regular intervals around the circumference of the disc. 
Each hemisphere shields a turreted X-ray laser in the 200 MW 
range. Guidance and firing are carried out either by the master 
gunnery control station on Deck 1, or by individual turret controls on 
Deck 3. 


Three extendable struts are located at regular intervals on the 
underside of the device, and can be extended for landing. 


SCP-2461-B: Ten instances of SCP-2461-B were found inside 
SCP-2461-A, labeled SCP-2461-B1 through SCP-2461-B10. At the 
time of the writing of this article, seven instances of SCP-2461-B (B1 
through B7) have been destroyed through testing or accident, 
leaving three extant examples. 


SCP-2461-B is an exoskeletal "powered armor" suit constructed of a 
highly sophisticated steel alloy. Each was originally worn by a 
different instance of SCP-2461-C before recovery, and was 
individually fitted to its wearer's physical characteristics. 
Experimentation has revealed that SCP-2461-B grants the user 
increased strength, that its armor plating is capable of repelling 
small arms fire up to and exceeding .50 BMG, and that it contains 
systems capable of life support in hard vacuum for extended periods 
of time. 


SCP-2461-C1 through C12: The cremated remains of twelve 
individuals (eleven male, one female) who originally operated 
SCP-2461-A. At the present time, none of the SCP-2461-C 
instances have been positively identified. Autopsies carried out after 
the initial crash site recovery indicates that all ten individuals were 
killed [DATA EXPUNGED]. 


SCP-2461-D1 through D 10: Ten devices originally housed in 


leather holsters affixed to the exterior of each SCP-2461-B. Eight of 
these devices (SCP-2461-D1 through D8) were damaged beyond 
repair in the impact. One of the surviving devices was subsequently 
destroyed during the course of experimentation and testing, leaving 
one extant device remaining. 


SCP-2461-D is an X-ray laser pistol in the 150 kW range. The 
emitter is located in the bulbous structure located just above the 
grip. The collimating "barrel" of the device is a hexagonal prism 
made of an artificial aluminum oxide crystal, protruding four inches 
from the emitter, surrounded by combination heat-sink and barrel 
shroud. The devices are rechargeable by 125 V alternating current, 
or by replacing the power pack located in the grip. 


SCP-2461-E1 through E4: Four X-ray laser rifles in the 200 kW 
range. The construction is similar to that of SCP-2461-D, except that 
the power pack is located in a magazine well located forward of the 
trigger housing, the barrel has been extended to twelve inches and 
includes a forward hand grip made of walnut wood, and a rifle butt 
made of the same walnut wood has been attached to the rear of the 
laser emitter housing. 


SCP-2461-F through Z: [DATA EXPUNGED UNDER SECURITY 
PROTOCOL 999-2461-GERNSBACK] 


SCP-2461-ALEPH through HE: [DATA EXPUNGED UNDER 
SECURITY PROTOCOL 999-2461-GERNSBACK] 


Addendum: Initial Recovery and History. SCP-2461-A (and all 
artifacts contained within) were originally recovered from , on -
