In the *** of Worlds Known Space books by Lerner and Niven a species called the Gw'oth is introduced. They interact with humans and Puppeteers in the novels and eventually establish their own colony planet. Both humans and Puppeteers learned from Beowulf Shaeffer's core expedition in "At the Core" that the center of the Milky Way galaxy is experiencing a chain reaction of supernovae. A flood of hard radiation and energetic particles will sleet through Known Space and the galaxy's spiral arms in twenty thousand years. Upon hearing the news the Puppeteers took their planets and ran, fleeing the galaxy at a significant fraction of lightspeed. Humans in Known Space apparently think tens of thousands of years is plenty of time to figure out what they should do when the time comes. But I don't remember anyone ever telling the Gw'oth about the upcoming calamity.
Before I embark on rereading fifteen hundred pages of twisty plot and intrigue I thought I would ask here:
Do the Gw'oth know that the galaxy is exploding?
