Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX-A is to be kept in a large, square enclosure, at least five hundred (500) kilometers across with no roof. The enclosure must have walls at least 50 meters tall with a thickness of at least five (5) meters constructed from highly radiation-resistant material. The walls may not have doors; entrance into the enclosure must occur via the open roof.
The floor of the enclosure must contain an array of nuclear fusion cells. The array should be activated every two (2) hours. Personnel entering the enclosure should be equipped with maximum level radiation-resistant suits and personal, handheld nuclear fusion cells.
Personnel exploring SCP-XXXX-C must wear a spacesuit outfitted with an antimemetic field disruptor and provided amenities necessary for extended survival in intergalactic space. Exploration of SCP-XXXX-C is forbidden following the events of Test XXXX-6 under order of the site administrator.
Description: SCP-XXXX-A is a hollow steel cube with a side length of 3 meters. The cube has a one (1) meter by one (1) meter door centered on one face and a two (2) meter by two (2) meter door centered on the opposite face. Opening the first door reveals a series of interconnected gears, pistons, and pulleys moving of their own accord (SCP-XXXX-B).
Opening the second door creates an immeasurably sized temporospatial anomaly (SCP-XXXX-C) located inside of SCP-XXXX-A. SCP-XXXX-C instances are exact replicas of the universe at the moment of creation, in which time passes considerably faster. Approximately [DATA EXPUNGED] years pass in SCP-XXXX-C for every second that passes outside of it.
SCP-XXXX-B generates a antimemetic field within instances of SCP-XXXX-C which prevents those affected from realizing that they know that they are inside of an instance of SCP-XXXX-C. This field is known to be undetectable from inside of SCP-XXXX-C. Upon exiting SCP-XXXX-C, individuals are once again capable of realizing that they were in SCP-XXXX-C.
Exceedingly hostile and resistant humanoid entities (SCP-XXXX-D) ranging from five (5) to [REDACTED] meters in height routinely appear within [REDACTED] kilometers of SCP-XXXX-A. How instances of SCP-XXXX-D appear is currently unknown. The only method determined for destroying instances of SCP-XXXX-D is bombarding instances with high concentrations of gamma radiation.
Addendum:
DO NOT close the door to an SCP-XXXX-C instance while personnel are inside! - Dr. ██████
Test XXXX-1
Subjects: D-18762, armed with a standard issue M4 carbine, and D-33915, armed with a flamethrower. Both wear live-feed, head-mounted cameras.
Purpose: Determine the resistance of SCP-XXXX-D instances
Details: D-18762 and D-33915 are brought into the enclosure via helicopter and provided equipment. The D-class personnel are then instructed to locate and kill an instance of SCP-XXXX-D. After 5 minutes, a loud shriek is heard through the cameras and the D-class personnel turn towards the sound. A fifteen (15) meter tall instance of SCP-XXXX-D is visible approximately 20 meters away, quickly approaching the D-class. D-18762 opens fire on the instance, to no avail. The bullets ricochet off of the instance's skin and one of the bullets catches D-18762 in the leg causing him to collapse to the ground. D-18762 quickly stands back up and begins to limp away from the instance, now only 5 meters away. D-18762's camera suddenly rises into the air and hurtles towards a nearby wall before the feed cuts. D-33915's camera shows D-18762 being lifted into the air by the entity and thrown approximately [DATA EXPUNGED] meters per second at a wall where he appears to shatter. D-33915 concentrates fire on the instance, which continues moving towards D-33915 for 10 seconds before it is upon her. The instance suddenly slams its hand forward and D-33915's camera falls to the ground and begins rolling. After a few moments, the camera reveals D-33915's torso, crushed and torn.
Notes: Clearly, SCP-XXXX-D is highly resistant to both gunfire and incendiary weapons. - Dr. ██████
Test XXXX-2
Subjects: D-53288, equipped with an advanced timer, a spacesuit, and a radio
Purpose: Discern the rate at which time passes in SCP-XXXX-C instances
Details: D-53288 is told to enter the active SCP-XXXX-C instance and return once instructed. D-53288 enters the portal and starts the timer. D-53288 rapidly ages and decomposes completely after only [REDACTED] milliseconds pass. The timer is retrieved by an autonomous drone and the year reads [DATA EXPUNGED].
Notes: Time passes in SCP-XXXX-C much faster than anticipated, special procedures must be used in further testing. One thing doesn't make sense, though. Why didn't the D-class try to leave? - Dr. ██████
Test XXXX-3
Subjects: D-76835, equipped with a spacesuit and an atomic alarm clock set to flash after (15) minutes
Purpose: Extract a living test-subject (D-76835) from SCP-XXXX-C
Details: A high-speed camera is set up outside of SCP-XXXX-C. D-76835 is told to enter the active SCP-XXXX-C instance and return once the alarm clock flashes. D-76835 suffers the same fate as in Test XXXX-2. Examination of the high-speed camera footage reveals D-76835 expressing visible confusion when the alarm clock flashed.
Notes: The D-class, once again, didn't attempt to leave. I believe there may be some kind of antimemetic field in instance of SCP-XXXX-C. - Dr. ██████
Test XXXX-4
Subjects: Antimemetic Field Detector (AFD)
Purpose: Determine if an antimemetic field exists within SCP-XXXX-C
Details: An AFD was brought near SCP-XXXX-A. The AFD quickly determined that an antimemetic field existed within the SCP-XXXX-C instance. However, when the AFD was placed inside the SCP-XXXX-C instance in order to pinpoint the source, it did not detect the antimemetic field.
Notes: My theory about an antimemetic field seems to be correct, but the field is undetectable from inside of it… - Dr. ██████
Test XXXX-5
Subjects: Autonomous drone with live-feed
Purpose: Determine what happens to objects in SCP-XXXX-C instances when the door is closed
Details: The drone flies into the SCP-XXXX-C instance and the door is closed behind it. Upon opening the door again, the drone is no longer visible. The feed cuts as the door is closed.
Notes: It appears the drone ceased to exist. I made an addendum to the documents accordingly. - Dr. ██████
Test XXXX-6
Subjects: D-82991, equipped with a spacesuit with an antimemetic field disruptor and assisted by an autonomous drone with live-feed
Purpose: Explore SCP-XXXX-C
Details: D-82991 enters the SCP-XXXX-C instance with the drone and exits [REDACTED] nanoseconds later, several years older. D-82991 was then interrogated for what he discovered. The transcript can be found under Interrogation Log XXXX-82991.
Notes: Following new information brought to light by the recent interrogation, further testing is prohibited. - Site Director ███████ █ ████
Interrogation Log XXXX-82991
Interviewer: Dr. ██████
Interviewed: D-82991
Foreword: This interrogation was conducted immediately after Test XXXX-6, see relevant test logs for more information.
<Begin Log>
Dr. ██████: You look shaken, what happened in there?
D-82991: [Inaudible]
Dr. ██████: Sorry, I didn't catch that. Can you say it again?
D-82991: I said I saw the box.
Dr. ██████: What box?
D-82991: It was the same box as the one you told me to enter.
Dr. ██████: Elaborate.
D-82991: I went into the box, into that other universe, and I found the box.
Dr. ██████: You mean you found another box inside the box?
D-82991: Yeah. And I went in, and do you know what I found in there?
Dr. ██████: What did you find?
D-82991: The same box. That's when I decided to turn around, but something is still bothering me.
Dr. ██████: What's that?
D-82991: The device that I'm wearing, It's still blocking something.

Closing Statement: I have to report this to the Site Director… - Dr. ██████
