Right exactly that’s that I meant to say. So 5 billion light years traveled. An alien race would see it billions of years later. The universe is expanding but into what exactly. If it is boundless and endless does that mean once it expands to a certain point will everything then fall back and collapse on it self like the Big Crunch theory?
Yes, but does this mean obviously if there are other intelligences in space far enough away, they can see the light front the sun, but they’re seeing the sunlight as it was light years ago. Meaning they’re seeing it in the past.
