Spherets

Spherets are a theoretical concept in astrophysics, specifically within the realm of dark matter research. The term "spheret" is a portmanteau of "sphere" and "planet," suggesting a compact, possibly self-gravitating object. These hypothetical entities are proposed as a potential candidate for explaining the observed properties of dark matter. Unlike baryonic matter, spherets would not interact significantly with electromagnetic radiation, hence remaining invisible to conventional telescopes. Their existence is primarily inferred from their gravitational influence on visible matter, such as galaxies and galaxy clusters.

The theoretical framework for spherets suggests they could be composed of weakly interacting massive particles (WIMPs) or other exotic particles that would clump together under gravity to form these compact structures. If they exist, spherets would need to possess a certain mass range to satisfy cosmological observations without contradicting other astrophysical constraints. Researchers explore various scenarios for their formation and evolution, considering their potential interactions or lack thereof with ordinary matter. Detecting spherets directly is a significant challenge, and current efforts focus on indirect detection methods, such as searching for annihilation products or gravitational lensing effects. The concept of spherets remains speculative, and ongoing research aims to either confirm or refute their role in the dark matter puzzle.
