Has a lot of potential. A few things I would like to comment on. First of all your pretty much all your sci-fi/concepts need a better explanation. I know this is just a small taste but I think that you have to think more about your concepts and how you explain them. Because they may make sense to you because you created them and put possibly experienced them. But to most people it will go over their heads. A lot of your concepts seem like they would make the average engineer mad . Secondly I feel like people would not procrastinate if they knew they had only a few centuries to dream up a new universe. Are you going to try weaving time travel into the narrative or just space manipulation? Is there no way to reverse the damage done to the universe?

So yeah basically I am just recommending going through your stories with a fine tooth comb and making things make sense to an "average" reader. Convolution, Convolution, Convolution.
