Good work
I have a criticism though. You said everyone is happy at the end. However, since the sun was destroyed, it would be inevitable that most of the inhabitants on earth would die due to the lack of the sun. Crops would die out as well as all other plant life on the surface. With no plant life, that food source is gone, then animals that eat plants, that we breed for food would die. This would lead to the human race becoming extinct. So, my point is is that you should put anyone other than most inhabitants on earth were happy, because i odn't think people like to die.
