What is a Planck length?
The Planck length is about 1.6 × 10⁻³⁵ meters, the smallest length that has any clear meaning in physics. It comes from combining the constants behind gravity, quantum mechanics, and the speed of light.
No instrument can measure anything close to it. Physicists use the Planck length as a theoretical limit when they talk about how space itself might behave at the tiniest scale.
