We will demonstrate that if the curvature of photons is quantized and linked to the Planck length, then the bending of a photon in a gravitational field must likely be the Planck length per photon wavelength. If we apply this concept to the Hubble sphere, the longest possible wavelength that can be bent into the Hubble sphere correspond to a wavelength equal to the energy that very precisely predicts the CMB temperature. This leads us to the ability to predict not only the CMB temperature, but also provides a potential mechanism linked to the Planck scale for explaining why the CMB temperature is what it is. We further discuss how this is related recent theoretical findings related to the CMB temperature. It seems like more and more theoretical evidence points towards a solid foundations for that the CMB temperature clearly can be presicely predicted, not only measured as commonly assumed.
