abstract:In physics, the Planck length, denoted ℓP, is a unit of length, equal to . It is a base unit in the system of Planck units, developed by physicist Max Planck.
At its finest scale, weshould be able to probe down the "Plancklength" which measures 10-35 meters. But the GEO600experimentdetectednoise at scales of less than10-15meters.
However, he says Quantum Mechanics prevents anyone from claiming it would be smaller than a Plancklength, a length of measurement so miniscule that it would make a normal-sized atom look like an outsized sun.
