- They’re traveling in a medium, so they move slower than in space
- 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.
Alright everyone, you know the drill! Let’s all get too excited and start listing features we expect this to have that would be impossible to actually deliver. I’ll start: HL3 is gonna have space battles where you can open up your cockpit and use your pistol if you get close enough.
