👉 Mac:Light Particles, often referred to as LPP particles or light particles, are hypothetical subatomic entities proposed by physicist Sean Carroll and others in the context of quantum gravity and string theory. These particles are conceptualized as extremely light, possibly even massless, entities that could carry information about the quantum nature of spacetime. Unlike conventional particles like electrons or photons, which interact through specific forces, LPP particles are theorized to be fundamental building blocks of the universe, potentially mediating interactions at the Planck scale—where quantum effects of gravity become significant. They are characterized by their extremely low mass and high velocity, making them difficult to detect with current technology. The study of LPP particles aims to bridge the gap between quantum mechanics and general relativity, offering insights into the fabric of spacetime and the unification of fundamental forces.
