SUMMARY
The Planck length, defined by the equation \(\ell_{p}=\sqrt{\frac{\hbar G}{c^3}}\), is a universal constant derived from three fundamental constants: the reduced Planck constant (\(\hbar\)), the gravitational constant (G), and the speed of light (c). Since these constants do not vary with different frames of reference, the Planck length remains invariant across all contexts. This establishes the Planck length as a fixed quantity in physics, independent of relativistic effects.
