I'd say practical hands on knowledge of planets, stars, and various celestial objects is extremely advanced. The ability to not just find and traverse wormholes (which are merely theoretical in real life), but CREATE them.. speaks of a very very strong aptitude for astronomy. I suppose that's to be expected of a space-faring species.
This, pretty much. A society in which the wholesale fiddling with spacetime that allows for the warp drive (well, assuming it's an Alcubierre-esque drive, which actually
makes sense compared to the 'PF' explanation and can neatly tie of some of the weirder aspects of spaceflight in EVE) and wormholes to not only be possible but commonplace would, by definition, have to have a damn advanced knowledge of physics.
As for looking through telescopes at distant stars they cannot reach, and navigation to/from those stars without using easy-mode jumpgates and cynos? I'd say it's probably about the same as it is now. I would assume most of the technology for observing the stars from a distance is fairly mature by now, with little in the way of innovation or difference.
Even so, compared to modern technology, it's probably much more powerful. Maybe using a wide range of integrated long range sensor technology and other theoretical hogwash to supplement the EM scanning? We already look at the stars from Gamma to Radio and everything in between. Maybe they have other non EM spectrums they check the skies with too?
Aside from more advanced sensors or whatever, yeah, I'd agree; the only difference, I suppose, is that with FTL comms and more sophisticated drones, it'd be far easier to get much more precise data in a shorter timeframe.
I know what RADAR and LADAR are, but I'm not sure what Gravimetric and Magnetometric (might simply be magnetics) are from a scanning standpoint. I would assume they encompass something new.
I've always assumed gravimetric to be a measure of its gravitational pull / however much the object distorts spacetime -- hence the massive asteroid belts found at gravimetric exploration sites. Similarly, I've run with magnetometric being a measure of the general 'electromagnetism-ness' around a body or site, with magnetometric exploration sites often being decaying or damaged advanced facilities. I almost certainly need to self-flagellate in the name of physics or something for using 'electromagnetism-ness', but hurried post is hurried.
To the OP, honestly, I'm unsure. It's self-evident that the rogue drones, the Nation and whoever else is active with access to wormholes or comparable has a
tremendous leg-up in that regard, if only because they don't need to establish a stargate before going to and from a system, but for the majority of the cluster? Have (comparatively) small unmanned ships been sent zooming off towards apparently suitable systems at relativistic speeds, filled with liquid ozone and fitted with a cyno to bring in a fleet of jump freighters to connect up a new system, say?
I'm not sure how far to take the speculation, since I first don't have much time at all, and second don't recall any PF mentioning anything related aside from the Old Man Star (I think?) chron.
