Skeletides

Skeletides are a proposed class of theoretical particles that could exist in certain cosmological models, specifically those involving modified gravity theories or alternative explanations for dark matter. The term "skeletide" is not a widely established scientific term and is more commonly found in speculative or fringe theoretical physics discussions.

The core idea behind skeletides is to provide a mechanism that could explain gravitational anomalies observed on galactic and cosmic scales without resorting to the standard model of dark matter. In some theoretical frameworks, these particles are hypothesized to interact very weakly with ordinary matter and other known forces, primarily through gravity. Their existence might arise from extensions to the Standard Model of particle physics or from entirely different theoretical constructs.

The properties and specific nature of skeletides would depend heavily on the particular theoretical model proposing them. They are generally envisioned as being non-baryonic, meaning they are not composed of protons and neutrons. Some theoretical treatments suggest they might be related to scalar fields or other exotic forms of energy that can influence spacetime curvature.

Currently, there is no direct observational evidence for skeletides, and their existence remains purely hypothetical. They are a product of theoretical exploration aimed at addressing unresolved puzzles in astrophysics and cosmology. Further theoretical development and potential future observational experiments would be necessary to either confirm or refute the existence of such particles.
