What is the Planck Scale?
In physics, the Planck scale refers to either a very large energy scale (1.22 x 1019 GeV) or a very tiny size scale (1.616 x 10-35 meters) where the quantum effects of gravity become important in describing particle interactions. At the Planck size scale, quantum uncertainty is so intense that concepts like locality and causality become less meaningful. Today’s physicists are very interested in learning more about the Planck scale, as a quantum theory of gravity is something we currently lack. Were a physicist able to come up with a quantum theory of gravity that agrees with experiment, it would practically guarantee them a Nobel Prize. It is a fundamental fact of the physics of light that, the more energy a photon (light particle) carries, the smaller a wavelength it has. For instance, visible light has a wavelength of around a few hundred nanometers, while the much more energetic gamma rays have a wavelength about the size of an atomic nucleus.
