Crowlspace looks at Kardashev 2 and Kardashev 3 Intergalactic Worldships
From
Kardashev 2 Worldship
A worldship that would require the power level of a Kardashev 2 civilication.
In 1987 Burruss & Colwell proposed such an advanced worldship concept.
* 1,000 kilometer wide World-Ship
* 50 billion passengers
* cruise speed of 0.4c (40% of lightspeed).
* The antimatter fuel required would be the equivalent of several days worth of the Sun’s total luminosity, so it would require at least a Kardashev Type II Civilization dedicated to the task to achieve it.

A Type III Civilization, with control over the Galaxy’s resources, could fling Intergalactic Planet-Ships outwards at 0.5c (50% of lightspeed). But what would it require to stop in the target Galaxy?
Given the right materials a magnetic-sail might do the job. We can slow an Earth-Ship from 0.5c to 0.005c in about 550,000 years (11% of the trip-time) over a braking distance of about 36,000 light-years.
