Strange7 is referring to this essay, especially section 6.
Wormholes sent to the Andromeda at near light speeds arrive in approx year 2,250,000 co-moving time, but in year 15 empire-time (setting year zero at start of expansion).
I still don’t get how you can get more than c×t³ as a colonized volume.
With wormholes you could travel within that volume very quickly, which will certainly help you approach c-speed expansion faster, since engine innovations at home can be propagated to the border immediately. And, of course, your volume will be more “useful” because of the lower communication costs (time-wise, & presuming worm-holes are not very expensive otherwise). But I don’t see how you can expand the volume quicker than c, since the border expansion will still be limited by it.
(Disclaimer: I didn’t read everything there, mostly the section you pointed out.)
