👉 Planckian is a term used in astronomy and physics to describe a type of light that has a wavelength that is very close to one, or Planck's constant. It refers to a very short wavelength, typically about 10^-35 meters, which is the smallest possible quantum length within the visible spectrum of light. This means that Planckian light does not have any quantum fluctuations and can be used as an accurate source of information in certain applications such as astronomy and physics.
