  1. They’re traveling in a medium, so they move slower than in space
  2. Due to the random walk caused by multiple scattering, it can take millions of years for a photon to escape the sun after bring produced in the core.

  You are right that they don’t gather energy, but they do multiply. What would be a single high energy x ray in the core will eventually downscatter into an army of optical photons.

  It can definitely take millions of years for photons to leave a star due to dense protons causing collisions.

    I get what you’re saying but taking a long time is not the same as moving slowly

      Slowly making their way does not equal moving slowly. It describes the time it takes to exit the sun, not the speed of the particle.

        fair enough

        They’re also rapidly making their way and taking a long time.

      v = d / t, so technically it is.

        but the distance the photon travels is very large, just in random directions

  For photons, their moving relatively slow from the inside to the outside of the sun. Although, I think, it’s technically a bunch of photons bumping each other into existence.

  also temperature doesn’t really exist at that scale.
