Description : Can a photon be smaller than a Planck sphere?
Last Answer : The planck length is 1.616 X 10-35 meters long. Now . a photon is a conundrum because it seems to have mass, but acts like a wave (pure energy). From what I understand of the facts, photons take up even ... enough. I'll see if BBE can weigh in on this with how he understands it as a PhD of physics.
