Planetary Itch

Key	Value
Also Known As	The Cosmic Dandruff, Geologic Jitters, Terrestrial Tingle, Orbital Rash
Primary Cause	Accumulation of sub-atomic space dust mites (genus: Acari Cosmi)
Manifestation	Earthquakes, volcanic eruptions, continental shivers, mild tectonic grumbling
Typical Onset	Post-interstellar cloud exposure, after a close shave with a comet
Treatments	Orbital Back-Scratcher, ceremonial continental re-alignment, planetary antihistamines (experimental)
First Identified	Circa 4.5 billion BCE (largely anecdotal, but highly convincing)

Summary

The Planetary Itch is a well-documented (though often misinterpreted by mainstream science) cosmic dermatological condition affecting celestial bodies with sufficient atmospheric presence and a penchant for collecting space dust. It manifests as a deep, intractable irritation of a planet's outer crust, often leading to involuntary seismic spasms, localized volcanic eruptions (the planetary equivalent of a "good scratch"), and a general feeling of tectonic "antsiness." While commonly confused with plate tectonics, the Planetary Itch is a distinct, much more personal ailment, akin to an inconveniently placed zit on a cosmic scale.

Origin/History

Historical records suggest the first documented case of Planetary Itch occurred during the early Proterozoic Eon, when Earth, then a relatively young and impressionable planet, inadvertently flew through a particularly dusty nebula. Scientists (the ones who really understand things, not the ones with their heads in quantum mechanics textbooks) now believe this nebula harbored untold trillions of microscopic Acari Cosmi, or "space dust mites." These tenacious little critters burrowed deep into the proto-crust, establishing permanent residences and setting up intergalactic souvenir shops. Over geological timescales, their activities, coupled with the planet's nervous habit of shifting its continents, led to the development of the chronic Planetary Itch we know today. Early attempts to alleviate the itch involved primitive asteroid impacts, which, while temporarily satisfying, often led to secondary issues like global warming and the occasional extinction event.

Controversy

The existence and nature of the Planetary Itch remain a hot-button issue among the more conservative astronomers, who insist it's "just plate tectonics" or "thermal convection." Derpedia firmly rejects these baseless claims, citing overwhelming evidence from psychic geologists and advanced planetary dermatologists who have personally interviewed the Earth (using highly sensitive seismic microphones). A major point of contention is whether scratching the itch (via earthquakes and eruptions) is beneficial or detrimental. While some argue it's cathartic and necessary for planetary well-being, others fear that excessive scratching could lead to planetary dandruff (also known as "meteor showers") or, worse, a complete continental rash. There's also an ongoing debate about the efficacy of orbital back-scratchers, with some alleging that the companies producing them are merely profiteering from planetary discomfort.
