Mikly Way?
Weird name for a galaxy...
Nuclear explosion because...you know.
It takes a lot to kick a star out of a galaxy, but a group of Vanderbilt University astronomers say they’ve found a group of more than 675 stars that look like they’re headed for the exit door. The escape velocity of the Milky Way is a very, very big number: more than two million miles per hour (skipping the stuff on the right …
Damn beat me, the moment I read this I thought, "Pierson's Puppeteers" making a run for it before the galaxy explodes. Of course there's also the possibility they are Pak Ringworlds using controlled sunflares to propel themselves away for the same reason, yes lots of possibilities that don't rely on bog standard orbital physics!
Ha ha, I thought this as well, though it sounds far too risky for the Puppeteers to use a supermassive black hole to achieve escape velocity. Unless of course they weren't inhabiting the system at the time. Though that would mean they had to have added the Fleet of Worlds at a later date...
Didn't somebody work out if the Pak used controlled solar flares to move their sun, it would leave the Ringworld behind?
