👉 IBM's Light Particles are a class of subatomic particles that were proposed by physicist John C. Martin and his colleagues at IBM Research in the late 1990s. These particles are conceptualized as having a mass much smaller than that of electrons or protons, typically on the order of picobars (10^-12 to 10^-11 grams). Unlike conventional particles, Light Particles are theorized to interact very weakly with matter, making them extremely difficult to detect and study directly. They are often discussed in the context of exploring new frontiers in particle physics, particularly in the search for dark matter candidates or in understanding the fundamental forces of nature. While they remain hypothetical, the concept of Light Particles has inspired experimental efforts and theoretical models, contributing to advancements in particle detection technologies and our understanding of the universe's most elusive components.
