A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).

  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 being 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.
