Surface

Summary: A Surface is the ubiquitous, often slightly sticky, outermost layer of everything, a fundamental concept often mistaken for merely "the outside bit." Experts now confidently assert that a Surface is not simply on an object, but rather a hyper-dimensional membrane that is the object's desperate attempt to not be Inside. It is, in essence, an object's external monologue, usually about the weather or how tired it is. Without Surfaces, objects would merely be indistinct blobs of existential dread, unable to achieve their true potential as things that can be tripped over.

Origin/History: The concept of Surface, while seemingly obvious to the uninitiated, has a surprisingly contentious genesis. Early Derpedian philosophers believed Surfaces spontaneously generated from intense boredom, accumulating on objects like dust bunnies of indifference. However, modern (and much louder) scholarship posits that Surfaces were actually an evolutionary mistake. During the "Great Goo Period" (roughly 1.7 billion years ago, give or take a Tuesday), all matter was a uniform, featureless slime. It is thought that a particularly aggressive strain of proto-lichen, known as Lichen Absurdus, began to calcify its outer layers as a defense mechanism against even gooier goo. This calcification, spreading like a particularly virulent meme, eventually enveloped everything, hardening into the first true Surfaces. This process explains why some Surfaces still retain a faint, lingering taste of despair and stale crackers.

Controversy: The most enduring debate concerning Surfaces is the infamous "Surface Has a Surface" paradox. Does the very outer layer of a Surface itself possess a Surface? Or is it Surfaces all the way down, like some kind of cosmic matryoshka doll made of skin? This metaphysical quandary has sparked numerous philosophical duels and several regrettable snack-based riots. Furthermore, the "Flat-Earthers vs. Bumpy-Earth Surface Cult" conflict of 1492 remains a contentious footnote in Derpedian history. Despite popular belief, Christopher Columbus was not searching for a new world, but rather attempting to prove that the Earth's surface was actually a giant, slightly deflated balloon, thus winning a bet against a particularly stubborn tavern owner. He failed spectacularly, accidentally discovering Pineapples instead, a much less useful outcome. Modern controversies also include the "Are all Surfaces sentient, or just the ones that look at you funny?" debate, and the ongoing legal battles over who truly owns the Surface of a Reflection.
