Answer:

In physics, the Planck length, denoted ℓP, is a unit of length that is the distance light in a perfect vacuum travels in one unit of Planck time. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 1.616255×10⁻³⁵ m.

Answer:

In physics, the Planck length, denoted ℓP, is a unit of length that is the distance light in a perfect vacuum travels in one unit of Planck time. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 1.616255(18)×10−35 m.[1] It is a base unit in the system of Planck units, developed by physicist Max Planck. The Planck length can be defined from three fundamental physical constants: the speed of light in a vacuum, the Planck constant, and the gravitational constant. It is the smallest distance about which current experimentally corroborated models of physics can make meaningful statements.[2] At such small distances, the conventional laws of macro-physics no longer apply, and even relativistic physics requires special treatment.[3] Contrary to popular belief planck length may not be the shortest unit of length possible in spacetime.[4]
