Minimoivia
Minimoivia is a theoretical concept in particle physics that describes a hypothetical particle with a vanishingly small, but non-zero, mass. The name is derived from the Latin "minimus" meaning smallest and "via" meaning way or path, suggesting a particle that exists on the smallest possible scale or in a minimal state. The existence of such particles is not currently supported by experimental evidence, but they arise in some theoretical frameworks as potential solutions to certain cosmological or particle physics problems. For instance, some theories exploring the nature of dark matter or the early universe might entertain the possibility of particles with extremely low masses. The precise properties of minimoivia would depend heavily on the specific theoretical model in which they are proposed. Their interactions with known forces and particles would likely be very weak, making them exceptionally difficult to detect. The search for any new fundamental particles, regardless of their predicted mass, is a significant area of research in physics, aiming to refine our understanding of the universe's fundamental constituents and forces.
