Item #: SCP-3658
Object Class: Euclid
Special Containment Procedures: SCP-3658 cannot be contained as it exists in a non-physical dimension. No physical projections of SCP-3658 have been discovered.
SCP-3658-1 is to be contained inside a glass capsule that has a radius of 1 cm, and a height of 6 cm. The walls of the glass capsule are 5 mm thick to lessen the chances of Quantum Tunneling.
Attached to the outside of the glass capsule is an apparatus that produces an axial magnetic field, and a quadrupole electric field. This apparatus forms a Penning trap to prevent SCP-3658-1 from making contact with the walls of the capsule and keep it suspended in the middle.
Another apparatus is placed 12 cm away from the middle of the glass capsule. This apparatus measures SCP-3658-1's magnetic field direction and electric charge which effectively collapses SCP-3658-1's wave function.
Description: SCP-3658 is believed to be an extradimensional entity that can freely move through time. It is currently up to debate whether if SCP-3658 is an entity who originated in the temporal dimension, or is an entity who was put in the temporal dimension by an external force/being.
SCP-3658 is an extradimensional entity that exists in the temporal dimension. SCP-3658 manifests itself onto the physical dimension as a subatomic particle with roughly the size of a proton. This physical manifestation is called SCP-3658-1.
SCP-3658-1 share some intrinsic properties with quantum particles, and might disappear when not under observation (Quantum Tunneling). After disappearing, SCP-3658-1 would instantaneously reappear somewhere in a 4 AU (598,400,000 km) radius from where it disappeared. This would suggest that SCP-3658-1 is capable of faster-than-light travel.
SCP-3658-1 also has the ability to generate radio signals with specific frequencies, amplitudes, and interval patterns. SCP-3658-1 uses this ability to send radio transmissions in an attempt of communicating.
Communication with SCP-3658 began with the Wow! Signal that was picked up by the ███ ███ █████ Telescope on August 15, 1977. Further communication with SCP-3658 requires the sender to follow specific directions given by SCP-3658 him/herself.
SCP-3658 seems to be highly intelligent as it encodes its transmissions in Binary, Morse code, etc.
SCP-3658 also changes its transmission location every after a message to minimize the chances of someone else picking it up. Specific coordinates on where the next transmission will be sent from is indicated at the end of the previous message along with the type of message encryption.
The first coherent message sent by SCP-3658 was received by the ███ ███ █████ Telescope two (2) minutes after it received the Wow! Signal. SCP-3658 communicated by sending an 8-minute long radio outburst patterned in Morse code with the signals of intensity 9 corresponding to a "dot", intensity E corresponding to a "dash", and intensity 5 corresponding to a "space". When translated back to English, the message spells out “Alcor Mizar”, which pertains to two stars located in the constellation Ursa Major. This transmission is known as "Transmission #0" and is the first of 89 known transmissions sent by SCP-3658.
Addendum: After Dr. █████ █████'s discovery of both the Wow! and Alcor Mizar signals, he immediately informed the ████ Institute, which has been a long-time partner of the SCP Foundation.
Dr. █████ █████'s colleague, Elijah ██████, was asked to be a full-time member of the SCP Foundation in order to conduct further research on SCP-3658.
Elijah ██████ was given access to the ████████ Telescope owned by the SCP Foundation, which acts both as a radio transmitter, and a radio receiver. Unlike the ███ ███ █████ Telescope which only received radio signals in 12-second intervals, the ████████ Telescope can receive radio signals in 1-second intervals. The ████████ Telescope was pointed towards the direction of the Alcor-Mizar star system starting on August 19, 1977.
List of declassified recorded "conversations" with SCP-3658:

+ Transmission #1: Alcor-Mizar (August 23, 1977)

- Transmission #1: Alcor-Mizar (August 23, 1977)

The ████████ Telescope has observed total radio silence in the vicinity of the Alcor-Mizar star system two (2) days prior to the received radio transmission. This was extremely unusual since there should be some kind of background noise anywhere in the universe. This suggests that this was done by SCP-3658 to minimize errors in receiving the radio transmission.
The message below is a translated version of the radio transmission received from the Alcor-Mizar star system. The original radio transmission was encoded in binary wherein a one (1) second long radio signal with an intensity of 5 corresponds to a "1", while a one (1) second long radio signal with an intensity of 2 corresponds to a "0".
The following message was decoded one line at a time once it was received but decoding stopped after the fourth (4th) line.

- Transmission #2: Markab (August 30, 1977)

Similar to the Alcor-Mizar Transmission, the ████████ Telescope also observed total radio silence in the vicinity of Markab two (2) days prior to the received radio transmission.
The received transmission was also encoded in binary, similar to the Alcor-Mizar Transmission, wherein a one (1) second long radio signal with an intensity of 5 corresponds to a "1", while a one (1) second long radio signal with an intensity of 2 corresponds to a "0".
The received transmission was only decoded after the questions were asked.

+ Transmission #18: Alnilam (January 11, 1979)

- Transmission #18: Alnilam (January 11, 1979)

Note: Transmission #18 is an experiment directed by Dr. ██████ ████████ in an attempt to answer if transmissions sent by SCP-3658 are in a state of quantum superposition. After Radio Engineer ████ ██████ has sent the first question, the Foundation will attempt to decode and read the succeeding answers without giving SCP-3658 the respective questions. Radio Engineer ████ ██████ will have the freedom to ask SCP-3658 any question he prefers.
Beginning from Transmission #█, the Foundation will start decoding the answer once its respective question has finished transmitting. This gives the Foundation a much more "direct" conversation with SCP-3658, and gives the Foundation an opportunity to ask follow-up questions. In spite of this, the Foundation still transmits the first question AFTER the entirety of SCP-3658's transmission has been received. After transmitting the first question, the Foundation can now begin to decode the received message.
The ████████ Telescope has observed total radio silence in the vicinity of Alnilam two (2) days prior to the received radio transmission.
The received transmission was encoded in Morse code wherein the signals of intensity 9 corresponding to a "dot", intensity E corresponding to a "dash", and intensity 5 corresponding to a "space".

1. When will World War 3 start?

+ Transmission #51: Regulus (April 18, 1982)

- Transmission #51: Regulus (April 18, 1982)

Note: Transmission #51 is also known as Operation ██████████, and is headed by Commander █████ ██████. The objective of Operation ██████████ is to pinpoint SCP-3658's exact location in our physical dimension. According to Dr. ███ ██'s research, it is impossible for SCP-3658 to communicate with our dimension, if it does not have a physical projection in our dimension in the first place. In order to pinpoint SCP-3658's location, Transmission #50 tells SCP-3658 that there was a malfunction in the ████████ Telescope's signal receiver and can only receive radio signals in 5-second intervals. The prolonged reception rate would force SCP-3658 to transmit radio signals over a longer period of time, making it easier for the ██████-██ Satellite to pinpoint its location.
The following questions asked are just used to stall SCP-3658.
The ████████ Telescope has observed total radio silence in the vicinity of Regulus two (2) days prior to the received radio transmission.
The received transmission was encoded in Morse code wherein the signals of intensity 9 corresponding to a "dot", intensity E corresponding to a "dash", and intensity 5 corresponding to a "space".

1. Time for me is what space is for you. Time does not flow through me but instead, I flow through time. I roam across an infinite array of time "frames" wherein each "frame" is the universe in a specific point in time. There I decide whether or not to change an event in order to shape history into what I want.
2. With the help of the inhabitants of your universe. Since I do not exist in your dimension, I communicate with your universe's people and ask them to change an event for me.
3. Again, I cannot answer that question.
4. Because humanity is not ready for the knowledge yet. But I assure you, you will know some time in the future.
5. I do not know the answer to that question. As far as I'm aware, I am the only being in my dimension.
6. I also cannot answer that question.
7. The next disaster will happen in [REDACTED] at [REDACTED]. This event will kill ████ people if allowed to happen. Preventing this event from happening is not detrimental to the balance of the universe. I suggest you take measures to prevent this event from happening.
You will receive the next message [REDACTED]. The radio signal will be transmitted from the star [REDACTED] and is encoded in [REDACTED].

+ Transmission #88: Procyon (December 21, 1985)

- Transmission #88: Procyon (December 21, 1985)

Note: After the ██████-██ Satellite was able to pinpoint SCP-3658's location. The transmission origin no longer "jumped" from one point of the sky to the other but instead followed a calculated path starting from Regulus. This was explained as the "Observer Effect" by Dr. ███ ██ and implies that SCP-3658 truly does have a physical projection, albeit a subatomic one.
The █████ Probe launched by the Foundation back in 19██ was tasked to intercept SCP-3658's physical projection. This transmission is the last transmission ever recorded before interception.
The ████████ Telescope has observed total radio silence in the vicinity of Procyon two (2) days prior to the received radio transmission.
The received transmission was encoded in Morse code wherein the signals of intensity 9 corresponding to a "dot", intensity E corresponding to a "dash", and intensity 5 corresponding to a "space".

We found you.

Addendum 2: After the capture of SCP-3658's physical projection, also known as SCP-3658-1, Dr. ███ ██ and his team has spent countless hours in trying to study SCP-3658-1.
Communication with radio signals between the Foundation and SCP-3658 continued even after SCP-3658-1's capture. Upon examination, it seems SCP-3658 communicates by using SCP-3658-1 as a radio transmitter and a radio receiver. Further experiments show that SCP-3658-1 is able to generate radio waves of any frequency, and amplitude.
Logs of the succeeding conversations between the Foundation and SCP-3658 are still classified under the direct orders of Dr. ███ ██. In spite of this, Dr. ███ ██ has stated that SCP-3658 clearly answered all of the Foundation's questions, but answers to these questions remain undisclosed to prevent any kind of time paradox.

The Interview

[LEVEL 5 SECURITY CLEARANCE REQUIRED]

[ACCESS GRANTED]

On February 27, 1991, six years after SCP-3658-1's capture, Dr. Van Yu attempted to communicate with SCP-3658 to ask about its origin. SCP-3658 noncompliance would result in its termination using the Large Hadron Collider.
Dr. Van Yu and SCP-3658 communicated with each other using radio signals in the 1420 MHz frequency (Hydrogen Line) to prevent any radio interference. SCP-3658's responses were in real-time.
The transcript below is only an excerpt. The entire conversation between Dr. Van Yu and SCP-3658 remains undisclosed. Only Dr. Van Yu himself has the transcript of the entire conversation

Dr. Van Yu: Can you tell me exactly what you are.Dr. Van Yu: What do you mean.Dr. Van Yu: So you existed in our physical dimension before? Which planet did you come from?Dr. Van Yu: You are human?Dr. Van Yu: Can you tell me what happened in the accident.Dr. Van Yu: Why do you want humanity to survive that much?Dr. Van Yu: But aren't you proof that humanity would still create a time machine regardless of any outside intervention?Dr. Van Yu: Who are "they"?Dr. Van Yu: A predestination paradox.
