Planck units — are units of measurement named after the German physicist Max Planck, who first proposed them in 1899. They are an example of natural units, i.e. units of measurement designed so that certain fundamental physical constants are normalized to 1. In … Wikipedia
Planck scale — In particle physics and physical cosmology, the Planck scale is an energy scale around 1.22 × 1028 eV (which corresponds by the mass–energy equivalence to the Planck mass 2.17645 × 10−8 kg) at which quantum effects of gravity become strong. At… … Wikipedia
Planck epoch — In physical cosmology, the Planck epoch (or Planck era), named after Max Planck, is the earliest period of time in the history of the universe, from zero to approximately 10 43 seconds (one Planck time), during which quantum effects of gravity… … Wikipedia
Planck mass — The Planck mass is the unit of mass, denoted by m P, in the system of natural units known as Planck units. Named after Max Planck, it is the mass for which the Schwarzschild radius is equal to the Compton length divided by π.:m P = sqrtfrac{hbar… … Wikipedia
