How can the Planck length and the speed of light both be universal constants? Will the Planck length change depending on your frame of reference?

Planck length is based on 3 constants, none of which change due to speed

[tex]\ell_{p}=\sqrt{\frac{\hbar G}{c^3}[/tex]

Since [tex]\hbar[/tex] , G, and c are all constants, planck length also remains constant
