Per 
SCP-XX81 observed as of 1994/08/01.
Item #: SCP-XX81
Object Class: Apollyon
Special Containment Procedures: SCP-XX81 has proven to be unaffected by baryonic matter, dark matter, anti-matter and negative matter. Due to these properties, no known way of stopping XX81 has been found. All matter coming contact with the space is erased from existance, thus making it impossible to contain.
Description: SCP-XX81, commonly known as the Capricornus Void by the public is devoid of all baryonic matter (such as atoms) and all quantum phenomenon. The diameter of the space is around two hundred and thirty mega parsecs (230 Mpc) in diameter. The Capricornus Void from now on referred as Nullspace, is around one hundred and twenty mega parsecs (120 Mpc) away from the Milky Way Galaxy.
Clearance: While knowing about SCP-XX81's existence is not a punishable crime, mostly because of it's "wide-spread" knowledge among the scientific community, especially the internet, It's true nature must not be revealed to the public or Foundation personnel below O5. All O5 members must be informed about the Nullspace's true nature, they can request A+ amnesics as to forget it. If an O5 requests this procedure, all other O5s must be informed. While it will not be punished, it is considered inappropriate to discuss or outright tell the affected people the true nature of the Nullspace.
Informing foundation staff or the general public about XX81 will be executed along with their families. Although the Nullspace doesn't become dangerous until 2200's, the world will fall into anarchy if the information gets out.
Addendum 1 : In 1994/08/01, an empty area of space was discovered. After further research it was discovered that the void had no baryonic matter contained, Instances of quantum fluctuations and cosmic background radiation has come negative. After [REDACTED] months it was observed that the void is expanding and "consuming" all matter in its path. This behavior was not observed in any other super voids, such as the Boötes super void, Eridanus super void nor in the Columbia void, thus earning the classification as an anomaly. Several tests have indicated the absence of not only matter but dark matter and dark energy.
Addendum 2
In 2003, The Nullspace has expanded 5.04 Mpc compared to its size in 1993, annihilating around 3785 galaxies. Using this information, SCP-XX81 is growing at 0.56 Mpc per year. On its current rate,
the anomaly will reach Earth in 214 years. It is also assumed that if the rate of expansion is constant, the Nullspace came into existence 410 years ago. When consuming matter, no energy is released violating Einstein's rule of special relativity. The Nullspace also conflicts with quantum field theory, true vacuum hypothesis, General and Special relativity, Hawking Radiation, The laws of thermodynamics and the conservation of energy. Currently no known explanation of the Nullspace exists
Addendum 3
In 2007/06/13, The Capricorns void was observed interacting with negative matter, resulting the temporary boost in the void's expansion rate going from 0.56 to 0.61 Mpc per year for 2 months. This contradicted the hypothesis that negative matter would reduce the rate of expansion. As of now, researchers at The Foundation hypothesize that Anti-Matter may stop the expansion of the Nullspace. This theory is yet to be tested.
Procedure
The experimental faster-than-light spaceship code named Black Star is to approach SCP-XX81. Aboard will be hosted a crew of 14, in a 1:1 gender ratio carrying 10 kilograms of Anti-matter. All subjects shall be Class B or above and volunteers. The crew should be volunteers and not be informed of the Nullspace's true nature. After reaching the destination, the crew will deploy the anti-matter container and guide it into XX81. The trip is projected to take [REDACTED] days.

The logs you are about to see is of the SCPS Discovery's transmission created by Dr. Zimwalt

Dr. Zimwalt: This is Dr Zimwalt aboard the Black Star. I have been tasked with keeping a record and putting it into audio format. Not the best job but who am i to complain? I wanted to go on this trip. Am i right Dr Arnold?
Dr. Arnold: Wait, What? You could *choose* to go on this mission? I was held at fucking gunpoint!
Dr. Zimwalt: Off to a great start. Anyways how come you were chosen on this mission? If you were held at gunpoint than you must be pretty important if you think about it
Dr. Arnold: Well, okay i wasn't held at gunpoint but i am pretty sure i would have been terminated if i were to declined,
Dr. Zimwalt: okay…
Dr. Arnold: Anyways, i have a PhD in String theory and an expert on Zitterbewegung phenomena. Not to brag or anything but if you asked. (Laughs)
Dr. Zimwalt: PhD in Quantum Physics. Have been working in this field for 24 years
Dr. Arnold: A pleasure to be in such a great company
Dr. Zimwalt: Zimwalt's log. Day 8. The food in the ca-
Dr. Arnold: Did you just call it Zimwalt's log? Really?
Dr. Zimwalt: Man, have some humor. A man gotta keep himself sane when all you see is black with spots of white on the window.
Dr. Zimwalt: As I wanted to say, the food taste like [REDACTED], it's horrible. Although i do not know what i expected. At least we can eat bananas. The Foundation has supplied us with infinite fruit thanks to SCP-[REDACTED]. These taste mildly sour but it still tasted like bananas, better than the awful stuff we get.
Dr. Zimwalt: Zimwalt's log. Day 17. Getting used to the paste. I would still eat something better but you gotta eat something. Tomorrow we are hosting a Pizza party. But instead of pizza, it's made out of paste and banana. Sounds disgusting but it's "pizza". We have also created a game with Dr Arnold. Tell them!
Dr. Arnold: (Speaking in the distance stops) Wait me? Oh! Yeah one second (Walks over to the microphone) You know the game where you sit in cars or trains and you count the different objects? I forgot the name
Dr. Zimwalt: I think it was binbo or something.
Dr. Arnold: This ageing brain just can't keep up. So basically we play binbo in space. Galaxies and stuff. Find 3 spiral galaxy, 2 quasar, 2 elliptical galaxies next to each other. All the good stuff.
Dr. Zimwalt: I once saw two galaxies merging into each other.
Dr. Arnold: Sure you did… Sure you did.
Dr. Zimwalt: Zimwalt's log. Day 18. We had banana pizza and holy [REDACTED] it was tasty. It was refreshing to eat something different.
Dr. Arnold: I bet if we didn't eat paste for 18 days, it wouldn't have been that tasty…
Dr. Zimwalt Come on man.
Dr. Zimwalt: Zimwalt's log. Day 25. Dear Foundation. We couldn't resist. We couldn't stop our urges. We….
Dr. Arnold: We had a giant fucking orgy on the ship and it was awesome!
Dr. Zimwalt: DOCTOR! Excuse the doctor's expression of the event, but this is sadly what happened. I am ashamed because of my inappropriate behavior againt the Foundation and my wife and kids.
Dr. Arnold: Come on man you were the BEAST! I haven't seen a man of your age go that rough on Doctor [REDACTED]
Dr. Zimwalt: Okey listen here you moth-
Dr. Zimwalt: Zimwalt's log. Day 39. Doctor [REDACTED] is pregnant. And anyone can be the father.
Dr. Arnold: (Whispers) Even you (Laughs)
Dr. Zimwalt: Zimwalt's log. Day 56. We are beginning to see a dark space ahead of us Control only told us to visit it, drop the package and document. Dr Arnold do you have any ideas what it could be?
Dr. Arnold: Supervoid. Pretty obvious. It's just an empty space. I mean it is not *empty*. There are galaxies there, planets, atoms, quantum particles etc.
Dr. Zimwalt (Whispers) Nerd
Dr. Zimwalt: Zimwalt's log. Day 72. It is so dark. Dark. Dark. There is nothing. Nothing. Didn't you say there were still stuff in there?
Dr. Arnold: Zimwalt I am as puzzled as you are. I don't know more than you. There should be stars, hell galaxies! They are not here.
Dr. Zimwalt I don't like this place Arnold.Dr. Arnold Me neither
Dr. Zimwalt: Zimwalt's log. Day 96. We are nearing the space. It takes up nearly 75% of our Field of View. It is the darkest place I have ever seen. So so dark. Unbelievably dark. And there is nothing. NOTHING. ARNOLD THERE IS NOTHING NOTHING
Dr. Arnold: Okey Zimwalt you need to calm down
Dr. Zimwalt: (Unintelligible screaming)
Dr. Arnold: This is Dr. Arnold at room 12B. I need assistance in Dr Zimwalt's craziness. Someone bring some herbal tea or shit I need HELP (Screaming)
Dr. Arnold Arnold's log. Day 122. I haven't seen Dr Zimwalt since the incident I fear the worst but nobody seen him. I have never felt alone in my life. Not in school, not in relationships. Even on this voyage I could always talk to Zimwalt. Now he is gone. Now, Now I feel alone. Radar can't detect this stuff, but we expect to reach this stuff in 12 days. This blackness. It is very dark. I- I can't explain how empty it is. How lonely I feel. I didn't think I would get attached to Zimwalt this way. He was my friend in the last days. He went crazy and if I don't do anything, I will too.
Dr. Arnold DON'T DO IT ZIMWALT. YOU HAVE SO MUCH TO LIVE FOR.
Dr. Zimwalt (presumably) I can't live on this ship anymore. I can't do it. I must end it.
Dr. Arnold THINK OF THE BABY. YOU MIGHT BE THE DAD.
Dr. Zimwalt I might be, but.. But..
Dr. Zimwalt No baby deserves the suffering that is this world.
Dr. Arnold ZIMWALT NO.
Foundation personnel have also observed a great explosion near the Nullspace. Most likely scenario is that Dr. Zimwalt have detonated the Anti-matter bomb aboard the ship. All connection was lost aboard the SCPS Discovery.
Results :
While in the case of baryonic, negative and dark matter the matter couldn't "penetrate" the Nullspace, clearly outline the border of it. In the case of antimatter, it could "penetrate". But it expanded it. After the unbelievably bright explosion, The void was already there. Dr [REDACTED] Compared it to this:
"Imagine this void as a river. It becomes wider and wider.
When we tried baryonic matter, negative or dark, it was like shoveling air into the river. It didn't do anythingWhen we tried antimatter, we exploded the river bank. We may have turned some water into space, but the river filled in the crater left by the explosion. We widened the river."
