so fascinating.. suns swallowing up other suns .. galaxies swallowing up other galaxies!! the size of these celestial objects is immense.. so hard to get my head around

Indeed, awesome observations.

Sometime this also happens using the "intergalactic transport network", a technical team which actually exists, exploiting low-energy transfer trajectories. See for instance http://www2.esm.vt.edu/~sdross/papers/AmericanScientist2006.... (especially its last page; sorry for linking to http) or https://www.youtube.com/watch?v=v4NTjTxdNug.
