Planck length and the speed of light

  1. Dec 18, 2009 #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?

    :)

    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
