Any thoughts?
If it's a probe then it makes sense it's looking for something and the fact it's not parked outside Sol indicates (to me) it's not looking for us. (We've been transmitting anything n everything into space for years so finding us shouldn't be hard)
The problem I have is time. I've spent so much time in a system known to have UA and I've found nothing. To prove the theory we would have to camp out in other systems/regions searching. That search will need to be quite an extended search to rule out non spawns of UA. The other approach, I.e. Head to those specific systems and search those might yield UA but not because of the system makeup.
I'm not against trying it, I just worry that I'm the time it takes to explore that possibility properly might be a little disproportiate
