How Big Is a Spaceship?
A hundred light years is a very big ramp and it is entirely plausible you might be shoving with energy beams able to push planet-sized ships up to speed. This is really feasible too though I think a binary system with a black hole and a donor star might work better. You could feed liberated matter via star lifting from the one into the other and achieve possibly as high a speed as 20 or 30% of light speed. Such a method could move a whole star system through intergalactic space and places as far away as perhaps 4 billion light years.
