We argue that travelling between galaxies—let alone between stars is very “easy”, for some values of “easy”. See http://www.fhi.ox.ac.uk/intergalactic-spreading.pdf or https://www.youtube.com/watch?v=zQTfuI-9jIo&list=UU_qqMD08PFrDfPREoBEL6IQ
Major cosmical restructuring would be trivial (under the assumptions we made) for any star-spanning civilization.
Thank you. Not entirely convinced, but at least I’m distracted for now by not knowing enough astrophysics. :-)
