Planck energy — In physics, the unit of energy in the system of natural units known as Planck units is called the Planck energy, denoted by E P.:E p = sqrt{frac{hbar c^5}{G approx 1.956 times; 109 J approx 1.22 times; 1019 GeV approx 0.5433 MWhwhere c is the… … Wikipedia
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
