Euclidean space, as presented in Minecraft. Unlike most non-Euclidean spaces, in Euclidean space parallel straight lines remain parallel to each other indefinitely.
In general, this isn't supposed to be any educational video about Euclidean space, but rather a pastiche/parody of the so-called "non-Euclidean" Minecraft videos. Please keep in mind that Euclidean space with weird connections is still Euclidean. "Non-Euclidean" has been misused many times to mean "weirdly-connected spaces". More about that:
