# Can a photon be smaller than a Planck sphere?

Asked by Bill1939 (8121)

Since a photon particle exists in the physical universe it seems to me that it could not be smaller than a Planck sphere, which would have a diameter of one Planck length. Viewing “Cosmos” number five I learned that an electron, while remaining within its fixed orbital, travels a distance greater than the circumference of its orbit. This led me to imagine that the surface of a Planck sphere could have movement without leaving the sphere’s area. In this way the sphere could have an electromagnetic vibration and could be a photon. Any thoughts about my conjecture?
