Far out . . . . . Further than the proof reader can see?

"It's like a laser beam. It's the most extreme explosion we know of. They are so bright and powerful we can witness them as far as we can see."

Exactly like everything else we can see?

There are plenty of phenomenon happening within the range we can see that are just to tiny or too far away to notice. The explosions they are talking about make a super nova seem dull by comparison.
I think the statement is fine, even if maybe on the face of it it seems a little silly. What they are saying is if this happens anywhere inside the range of our telescopes we are able to witness it.

It could have happened already. After all, it is 8000 light years away, which in turn is about 7.5% of the width of the Milky Way. So if it exploded today we wouldn't see the "big bang" for 8000 years. Ability to see has little to do with distance but more to do with space/time.

. . . . there's not a lot of things we can witness that are further than we can see. The only things that far out we know of are politicians' promises
