A materoid is a hypothetical particle that is theorized to exist within the framework of certain advanced physics models, often related to the study of dark matter and the fundamental forces of nature. While not widely recognized in mainstream scientific literature, the term may refer to entities that possess mass and interact through gravity or other forces. The concept typically arises in speculative discussions about the nature of matter beyond the standard model of particle physics. Further research and evidence are needed to substantiate the existence and properties of materoids.
