Planck energy, abbreviated as \(E_p\), is a fundamental unit of energy in the context of Planck units, which is a set of natural units that arise from combining fundamental physical constants in a way that simplifies various equations in theoretical physics.
Planck units, including the Planck energy, are often used in theoretical physics and cosmology to investigate the behavior of matter and energy at the smallest scales and in the most extreme conditions, such as those found in the early moments of the universe or near black holes. They provide a natural way to discuss physical quantities without relying on any arbitrary human defined units of measurement.
