I've always wondered what it would be like if there is a total black out in a big city. Now I can see it in these pictures. If the blackout isn't exactly simultaneous, would the stars slowly emerge one by one? How cool would that be!

Yes, they would. If you're in the middle of a remote desert during the day, you would be able to look up and see only blue sky. As the sun sets and the night becomes darker, you'll gradually see more and more stars until you see as many as you'll be able to when the sun is on the opposite side of the earth from you.
