172.69.22.157: …do y’all not realise that it’s a redlink

…do y’all not realise that it’s a redlink

172.69.79.191: It's pretty much a Flatland thing. Though the clincher for my undoing the removal is that the category was removed from two other comics with very obvious connections, without stated reason, so now I'm inclined to think it's a bad faith removal.

No Idea If There's A Character Limit LMAO: what was that tag for?

 The title text notes that 3D graphs that cross the relevant x and y coordinates, but with non-zero z coordinates whilst in that zone, should be fine, since the hole only exists in the plane where z = 0. However, if they pass close - i.e. the z coordinate is small in this region - they should be wary of two dimensional graph lines suddenly becoming three-dimensional and interfering with them. This could be because they have intentionally entered three-dimensional space to avoid the closure, or possibly they have inadvertently been 'launched' above/below the plane by the torn and warped edges of the surface. Or they simply fell into the hole, thus entering 3D space. This is similar to warnings to road traffic in open lanes being warned of traffic merging from lanes that have been closed due to works or any other general warning of increased congestion upon a parallel route used as a diversion.

-This comic is a "Math Notice," which is presumably a warning or reminder for mathematicians or others who interact with the field of mathematics, in a similar way to how a "Travel Notice" may prewarn drivers of planned road closures for repairs (or [https://www.cameroncountytx.gov/spacex/ rocketry]). It also has similarities to that of a {{w|Notice to mariners}} or {{w|NOTAM|air missions}}, where nautical or aeronautical navigation might be impinged by a clear area (or volume) that should be kept clear from in the near future, and to notices from websites or software providers about planned maintenance, which alert users about upcoming outages. Specifically, this notice advises those who are using the coordinate plane to avoid drawing any graphs in the area with a hole until the damage is patched or fixed.

 The joke may have been inspired as a response to the {{w|2023 China balloon incident}}, which occurred a few days earlier. This had occasioned one of the largest temporary flight restrictions, with a closed airspace as a response, in U.S. history.

 Closure can also be used in another sense, relating to the topology of a set; roughly speaking, a description of what parts of the set are "close" to others. In this sense, if one takes the closure of a plane with a hole, the result is indeed an intact plane, provided the hole is sufficiently (infinitesimally) small.
