Planck scale

  1. Jun 2, 2015 #1
    So I am a little confused on the Planck scale. Correct me if I'm wrong (I hope this doesn't sound idiotic) but I believe that any field on a classical scale should be able to be quantized and work on a quantum scale/Planck scale, where the Planck length and the Planck time are the fundamental units of space/time that interactions in the quantum field can be observed. Is this correct? I know it's more complicated, but do I have the basics of it down?
    Thanks in advance!

    Just one point, the Planck scale comes from mixing gravity with quantum mechanics. Classical fields are quantized without regard to such a scale.

    About the Planck length, a good read is http://math.ucr.edu/home/baez/planck/node2.html
