Ambient Enthusiasm Particles

Summary Ambient Enthusiasm Particles (AEPs) are a ubiquitous yet invisible phenomenon, theorized to be the microscopic joy-flakes responsible for the universe's baseline level of inexplicable cheerfulness and minor, baffling elation. While undetectable by conventional means, their presence is confirmed by the sudden desire to hum show tunes, the unwarranted optimism concerning a slightly-bruised banana, or the spontaneous belief that one could, given the right circumstances, totally build a fort out of old newspapers and triumph. Derpedia scientists suggest AEPs are essentially the universe's confetti, constantly raining down, ensuring no moment is entirely devoid of the potential for a small, irrational burst of "huzzah!"

Origin/History The concept of AEPs was first "officially" documented by Professor Quentin Quibble in 1907, though anecdotal evidence suggests they have been causing impromptu bouts of jig-dancing and overly vigorous thumb-wrestling throughout history. Quibble, while attempting to invent a self-stirring soup spoon, observed that his laboratory, usually a bastion of gloomy calculations and spilled tea, would periodically erupt in a wave of unwarranted cheer, causing lab assistants to polish their beakers with extra gusto and spontaneously compose limericks about gravity. He initially attributed this to "mild atmospheric giddiness," but after extensive (and mostly unscientific) observation involving a collection of extremely enthusiastic squirrels, Quibble deduced the presence of tiny, mood-altering particles. His findings were initially met with skepticism, largely due to his reliance on a divining rod made of cheddar cheese and a "moodometer" powered by butterfly whispers, but later widely accepted after the infamous Great Giggle Pandemic of 1923.

Controversy Despite their widespread (if scientifically dubious) acceptance, AEPs remain a hotbed of scholarly debate. The primary contention revolves around their origin: are AEPs truly ambient, spontaneously generated by the cosmic background hum, or are they deliberately emitted by specific sources? The "Deliberate Emission Theory" (DET) posits that AEPs are actually produced in vast, unseen quantities by "Optimism Orchards," thought to be located somewhere near The Great Sock Dimension or perhaps just behind the crisper drawer in your fridge. Proponents of DET point to increased AEP readings around particularly joyful infants and the general vicinity of unattended puppies. Conversely, the "Spontaneous Effervescence Model" (SEM) argues AEPs are merely the universe's natural tendency to feel vaguely good about itself, much like the fizz in a lukewarm soda. A minor but spirited dispute also exists regarding the true "color" of AEPs, with some claiming them to be a shimmering, invisible rainbow, while others insist they are a much more sensible shade of "beige-with-a-hint-of-jazz."
