Re: Old news

it already happened more than half a billion years ago !

In most contexts, this is an utterly irrelevant distinction. The propagation of information, and causality itself (if the universe is consistent and causality is maintained), are also limited to C; so "happened before we could see it" is largely a philosophical stance. When we're talking about astronomical distances, we can't be affected by it in any way until its light reaches us.
