I have, for many years, pondered the issue of 'when does light run out'?

Light itself must be an amazing thing as it appears to never diminish . . . or does it?

We look up at the Heavens with our unaided eye and see up to billions of years into the past, and even further with our Telescopes!! Our cameras catch light even further back in time and distance!!!!!!

OK, here's the thing: Light left a star billions of years ago, travelled for those billions of years, over multiple-trillions of kilometres, and is still shining bright!

When does 'light' actually wear out?
It MUST eventually.
If so, what else is out there that we are not quite seeing that has faded due to time and distance.
