Mkay, gave you a quick read. Heads up, your description looks like a wall of text. Make sure you space your paragraphs correctly and consider breaking up the text into smaller paragraphs for readability. Group like information together so that there's some logical flow/progression rather than just stats dump.
- The "at all times" bits in the containment can probably be removed. Generally, containment instructions are understood to always be in place at all times and any necessary deviations from that will be noted if any are present.
- No need to justify containment procedures, since it's assumed in-universe that the instructions aren't there for no reason. Stuff like "Due to the threat of atmospheric particles coming in contact with SCP-XXXX-2 and undergoing a potential self-sustaining nuclear fission cascade" can be trimmed down or removed entirely, since the audience doesn't need to know about all the potential emergencies that are possible, and in-universe staff just need to know how to keep the thing locked up.
- Is there any room for deviation from the measurements given in the containment? If those specifics aren't crucial to containment, consider providing range of acceptable values, or note that the specs given pertain to the containment that's currently in use, rather than the only containment that can ever be acceptable.
- I'm not too sure about the description. You have a sentence about "PRL Particle Sim 3.1 is a particle physics simulation program which allows users to manifest, and input forces to apply to SCP-XXXX-2." and I really want to know more about that and what XXXX-2 even is, but then there's information about the beach ball. Consider re-organizing that paragraph.
- Also, maybe introduce what XXXX-2 actually is before telling the audience details?
- It is never stated what SCP-XXXX is.
- I'm not sure why this object is Euclid. Seems rather harmless so long as no one's messing with it.
I dunno. I'm not one for stats-heavy SCP articles, so I can't say I found this too interesting. Also I'm not really sold on the core anomaly. Definitely get some more physics-savvy reviewers on this; they can also help you with structuring the article for readability/flow.
Thanks for offering your views. I'll do what you said regarding the wall-of-text, and other issues that arose when I copy/pasted from Word.
The measurements in the article are the measurements of the vacuum chamber the beach ball manifested in when it broke, and it can't exactly be changed due to risk of particles released during construction causing a self-sustaining nuclear fission cascade.
Overall, thank you, I'll work on the general structure next time I get on my PC.
