masslesstheir

Masslesstheir is a neologism that has appeared in a small number of online essays and speculative discussions. It does not denote a widely recognized physical theory or mathematical construct in mainstream science.

Typically masslesstheir is described as a hypothetical class of entities that are massless yet carry some form of persistent identity or agency, expressed through a field or information imprint. Proponents use the term to explore how information might be conserved or transmitted without energy or mass, and to illustrate conceptual tensions between massless propagation and attributes usually linked to mass or charge.

Etymology and origins are uncertain. The term appears as a portmanteau of massless and their, emphasizing gender-neutral pronouns; earliest published usages are found in blogs and forum discussions rather than formal literature.

In practice, interpretations vary. In some narratives, masslesstheir is a stand-in for particles that carry informational attributes about attribution or authorship; in others, it is used purely as a metaphor for identity within distributed systems or social discourse.

Because there is no stable, peer-reviewed definition, masslesstheir remains a niche or speculative term rather than a conventional scientific concept.
