The circle and the arc are cosmological neighbours to one another, not to us. They are close enough to each other.

The circle and the arc are cosmological neighbours to one another, not to us.
They are close enough to each other.
- denton-scratch 2y agoFair enough; but the article doesn't mention how close together they are. Judging from the diagram, they're separated by an angular distance roughly the same size as the larger structure; so about 3 billion LY.
- kuschku 2y agoIf you've got two structures of size X, with a distance of X between them as well, that's relatively close. That's as if Paris had a second Eiffel tower three blocks away.
- denton-scratch 2y agoYeah, that makes sense if Paris is just 15 blocks across, and the Eiffel Tower is a couple of blocks wide, and there's nothing (observable) outside Paris.
- Gooblebrai 2y agoAnd that doesn't even mean they are really close between them linearly.
