Planck length and the speed of light

  1. 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?

    :)

  3. 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
