What Does HDM Stand For?
HDM stands for Hot Dark Matter
HDM, or Hot Dark Matter, refers to a theoretical form of dark matter characterized by high-velocity particles that are relativistic at the time of the universe's formation. Unlike Cold Dark Matter, which moves slowly and clumps together to form structures, Hot Dark Matter is thought to have a more uniform distribution due to its rapid movement, influencing the formation of cosmic structures differently. This concept plays a crucial role in cosmology and astrophysics, particularly in understanding the evolution of the universe and the distribution of galaxies.
