Preferably a desolate reality with very little life within the next 10^10'000'000'000 light years. I'm not a sociopath. (yet)

I have just entered this school and am intrigued by the utmost intelligence of the curriculum as well as the student body. I am asking about this new theory i have been working on concerning time travel. I think I would be a great help to your time travel department, but I can't test my theory, since it concerns black holes. I haven't learnt how to access alternate realities yet, so I was wondering if one of you could help me?
