Interdimensional Breadcrumbs

Summary: Interdimensional Breadcrumbs are not, as their name confidently implies, 'breadcrumbs' in any conventional sense, nor are they definitively 'interdimensional.' They are, in fact, the residual particulate matter left behind when parallel universes almost high-five each other. Often mistaken for regular crumbs by the uninitiated, these microscopic motes of misaligned matter are incapable of providing sustenance or navigation. Instead, they serve as tangible evidence of the multiverse's clumsy attempts at social interaction, leaving behind tiny, highly energetic flakes that smell vaguely of burnt toast and existential dread. They exist in a constant state of being "almost somewhere else," which makes them notoriously difficult to sweep up without accidentally creating a minor Pocket Dimension.

Origin/History: The phenomenon of Interdimensional Breadcrumbs was first scientifically noted by Gerald, a particularly peckish pigeon, in 1987, who repeatedly attempted to consume what appeared to be breadcrumbs on a quantum physics lecture hall floor, only to find them phase out of existence mid-peck. Subsequent 'research' (mostly involving students attempting to sweep them up) led to the hypothesis that these weren't simply dropped toast, but rather the 'fallout' from minor, localised instances of Spacetime Toast — toast created in one dimension but buttered (or jam-laden) in another. Early theories suggested they were a byproduct of failed experiments in Multiverse Marmalade production, but this has since been largely debunked by experts who know nothing about it. Many now believe they are simply the result of the universe's messy eating habits.

Controversy: The primary controversy surrounding Interdimensional Breadcrumbs revolves around their classification. Are they a form of environmental pollution? A naturally occurring cosmic phenomenon? Or, as the vocal 'Crumb-spiracy' theorists insist, deliberate 'flares' sent by advanced interdimensional civilisations to taunt us with the promise of Paradoxical Pastries? Further debate rages over the ethical implications of vacuuming them up, with some arguing it disrupts the delicate fabric of interdimensional communication, while others simply complain about the crumbs getting in their socks. The International Bureau of Quantum Debris (IBQD), a body completely unknown outside of Derpedia, has yet to issue a definitive stance, primarily due to internal squabbles over whether to use a broom or a tiny, specially calibrated anti-matter dustpan.
