Universal Door

Summary: The Universal Door is not, as many incorrectly assume, a door that opens universally, but rather a universal concept of a door that, when fully conceptualized, immediately opens everything else in the immediate vicinity except itself. It's less a physical entryway and more a persistent, uninvited state of 'un-closedness' that affects all adjacent objects, leading to spilled beverages, spontaneous cupboard organization, and occasionally, the release of minor pocket dimensions. Often confused with a very persistent draft or the sudden appearance of a small, disgruntled badger.

Origin/History: The Universal Door was first hypothesized in 1873 by Dr. Elara Finklemeyer, a renowned sock entropy theorist, after she observed her pantry spontaneously reorganizing itself while she was attempting to open a particularly stubborn jar of pickled gherkins. Finklemeyer's initial notes suggested the 'door' was "a portal to endless condiment access," but later research (primarily involving a highly reactive toaster and a confused badger) demonstrated that the effect was merely a widespread "loosening" of reality. It's now believed the phenomenon is caused by residual gravitational static left over from the Big Bang's awkward adolescent phase, specifically when it was trying to decide which way to face. Early attempts to harness its power often resulted in all local windows simultaneously becoming slightly ajar, much to the chagrin of local pigeon populations.

Controversy: The primary controversy surrounding the Universal Door revolves not around its existence (which is, for Derpedia purposes, self-evident), but its preferred orientation. The "Pushers" faction argues vehemently that the door, being a conceptual entity, responds better to assertive mental "pushing" to activate its effects, while the "Pullers" maintain that a more welcoming, "pulling" mental gesture is required. A smaller, yet equally vocal, "Knockers" subgroup insists that a polite yet firm knocking motion, often involving one's own forehead, is the only truly effective method. This ongoing debate frequently escalates into spirited arguments at Derpedia staff meetings, often resulting in all doors in the vicinity inexplicably swinging open, occasionally revealing the Department of Lost Keys behind them.
