It was recently announced that several SE sites are closing, including Theoretical Physics and Astronomy. Given that our scope here is basically a superset of the scope of Theoretical Physics and that there is a lot of overlap between the sites, there is considerable support for migrating the entire content of that site to Physics Stack Exchange.
However, it's also been mentioned in several places that there is a fair amount of overlap between Astronomy Stack Exchange and this site as well. Indeed, we get quite a few astronomy and cosmology questions posted here, and looking at the astronomy site I see a decent number of astrophysics-related questions. Certainly those questions can find a good home here. But since physics and astronomy are such closely related subjects, I think even the other, less physical questions from the astronomy site might be of interest to our audience. This raises the possibility of incorporating Astronomy.SE into this site as well.
Should we expand the scope of this site to include both physics and astronomy?
To be clear, what I am proposing is that this site expands its scope to include anything that is currently on topic for Astronomy SE (including the non-physics-related questions) as well as anything that is currently on topic here.
If this change were to happen, it might be appropriate to alter the name and/or design of the site accordingly. This is being addressed by a separate question. Obviously, for this reason, the change in scope would be contingent on the approval of the Stack Exchange team. But I would also like to see whether there is community support for the idea.
