Cool...
Im a bit of an armchair astro phiz on the sly.
I learned something about the sun i didn't know last night.
When a photon is produced in the centre of the sun....its so dense...it can bounce around for some time before it escapes and lights us up....what we call sunlight.
This can take 40,000 years lol.
The light we see is tens of thoudands of years old
Wow!
