I've seen a lot of threads where people ask the devs to implement interstellar travel - but the question is, how would interstellar travel actually be implemented in KSP? There would have to be a galaxy for the stars to be in, and this model explains how I think the devs might implement such a galaxy (of course we won't be seeing the galaxy any time before KSP 1.0). I whipped it up on Paint, so I apologise if it's a little bit lacking in the quality side of affairs. The bigger star on the bottom arm is the Kerbal system. It is surrounded by other stars, as are other large stars on the other arms of the galaxy, all of which are orbiting that big white thing in the middle - a supermassive black hole to study for scientific purposes (or just chuck your Kerbals into). Each of the coloured dots may represent different stars: for example, a red dot could indicate a red (super)giant, a blue dot could indicate a blue (super)giant, a white dot a white dwarf, and a yellow dot a yellow star (like the Sun). The light blue dots close to the centre of the galaxy are supposed to be Neutron Stars - which could be explored or even mined to collect super-dense materials to research in career mode. The green rings around the galaxy are the orbits of Rogue Planets - i.e, planets without a parent star. These, if implemented, could be quite interesting, and along with neutron stars, could potentially be mined for new, advanced materials for research. Procedurally-generated wormholes could appear occasionally in the galaxy also - I'm thinking gateways across the galaxy to make pan-galactic travel easier, and possibly (with a sufficient tech level) even be modified to create portals to other stars. Now, this is nowhere near official, and the devs may have something entirely different in mind to my model, but this is how I think a possible galaxy would work. Perhaps interstellar travel could be achieved via exploiting heliopause (the point where the SoI of one star ends and that of another begins), or as I mentioned above, wormholes - or something entirely different altogether. Discuss!
