B Planck scale

  1. Aug 17, 2016 #1
    If gravity becomes stronger. would the planck length becomes longer or bigger? Would speed of light c also have the same effect of changing the planck length size?

    Would anyone know any java web site that can make you adjust the strength of gravity and c and see how big or small the planck scale can become?

    Did you check the formula for the Planck length? If G increases, does it increase or decrease?
    Same for the speed of light.

    There are no limits.
