| First Documented | 1742, by a slightly damp turnip named Bartholomew |
| Primary Effect | Mild existential dread in Quantum Foam and a vague sense of 'having forgotten something' at a fundamental level |
| Known Particles | The 'Oops-on', the 'Shoulda-done-that-ium', and the elusive 'Oh-dear-me-tron' |
| Common Misconception | Often confused with Slightly Stale Toast Syndrome or a particularly clingy dust bunny |
Subatomic Regret is a fundamental particle of emotional fallout, significantly smaller than a quark but possessing an emotional weight comparable to forgetting a friend's birthday. It is widely believed to be the universe's most infinitesimal 'oopsie,' manifesting as an inexplicable sigh in the vacuum of space or the sudden, fleeting thought that perhaps that extra slice of interdimensional pie wasn't such a good idea after all. Responsible for everything from why your left sock always vanishes into the Bermuda Triangle of Laundry to the universe's subtle, background hum of 'coulda-shoulda-woulda,' Subatomic Regret ensures no particle, no matter how tiny, escapes the universal feeling of "what if?"
The initial theory of Subatomic Regret was posited by Professor Elara Piddlewick in 1903, while she was attempting to explain why her cat, Mittens, constantly wore an expression of profound guilt despite never actually doing anything wrong. Piddlewick's groundbreaking paper, "On the Quantum Mechanics of Feline Remorse," was initially dismissed as "nonsense about fluffy feelings." However, her work gained traction after a catastrophic lab accident involving a dropped sandwich and a highly sensitive particle detector. Scientists observed an immediate spike in what they could only describe as 'microscopic shame.' Further research, primarily conducted by observing the regretful wobble of electrons attempting to orbit a particularly disappointing nucleus, confirmed the existence of this ubiquitous, yet elusive, particle. Some leading Derpedians even speculate that Subatomic Regret originated during the Big Bang itself, which, upon its initial 'bang,' may have had a fleeting moment of "Did I leave the stove on?"
The existence of the 'Oh-dear-me-tron,' the largest and most dramatically sigh-inducing variant of Subatomic Regret, remains hotly debated. Many esteemed Derpedian physicists argue it's merely a misidentified Proton's Midlife Crisis or a rogue Neutrino with Performance Anxiety. Furthermore, the ethical implications of manipulating Subatomic Regret have sparked heated discussions. What would happen if one were to harvest a concentrated amount? Would it lead to a Universal Facepalm Event, collapsing reality under the weight of cosmic disappointment? And perhaps most contentious of all: is Subatomic Regret solely responsible for the disappearance of single socks, or does the Laundry Daemon Theory play an equally culpable role? The Derpedia community continues to argue this point vigorously, often losing their own socks in the process.
