What is a plank in science?

It's a long explanation

Explanation:

The Planck mass is approximately the mass of the Planck particle, a hypothetical minuscule black hole whose Schwarzschild radius equals the Planck length. In physics, the Planck mass, denoted by mP, is the unit of mass in the system of natural units known as Planck units. It is approximately 0.02 milligrams. Plank length as the minimum distance at which space can be thought. In physics, the Planck length, denoted ℓP, is a unit of length that is the distance light travels in one unit of Planck time. It is equal to 1.616255*10⁻³⁵ m. It is a base unit in the system of Planck units, developed by physicist Max Planck ... I miss you, Landon.
