Can a photon be smaller than a Planck sphere?

Can a photon be smaller than a Planck sphere?

1 Answer

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 less space than a planck. Again, this is really unprovable ideas of quantum physics and I haven’t studied quite enough. I’ll see if BBE can weigh in on this with how he understands it as a PhD of physics.
