When it all goes dark

I've never written a novel before and am terrible at writing, this was written at a mere whim of mine so unless people like this ill probably drop it soon, saying that here's the description.

Sebastian an apathetic scientist sits in a spaceship orbiting the last known black hole in existence watching as the tiny celestial body finally winks out of existence, the explosion of energy bracketing his ship, he watches as the functions of his ship turn of one by one in a futile attempt to save energy before finally everything goes dark. as time passes he waits for his imminent death, except it never comes, what's going on?
