Forgive my ignorance. If it's so relatively close, why wouldn't it be observed optically hiding some known objects? Mostly stars.
Think about the funding this would unlock: long-duration deep space missions, particle accelerators in space, etc…
It would be a new renaissance for science.
Relatively close is still frightfully far away.

It's angle subtended is still awfully teeny.
