"Do you have any idea what'll happen to us inside the black sun?"
"Whatever it is, I just hope it's interesting."
The Moon is drawn inexorably towards a black sun, an area of intense gravitational pull that is the remains of a collapsed stellar mass. A reconnaissance Eagle is torn apart by the phenomenon and Koenig estimates that the Alphans have only three days before they suffer the same fate! Bergman designs a force shield which offers a slim chance for those on the base but Koenig also elects to launch a survival Eagle with a crew of six, in the hope that they might escape the pull of the sun and find a planet to live on. As the Moon plunges into the sun, Koenig and Bergman become discorporeal and meet an omnipotent being who reveals the secrets of the universe...
