In string theory, there is something called “winding number.” This winding number says that it is mathematically correct to say that the universe is its present size and growing larger, AND is the inverse of that number (smaller and getting smaller). See “Elegant Universe” for more detail. Also, James Gardner in “Biocosm” proposes his selfish biocosm hypothesis, that the universe may have been artificially created using a black hole - cosmic origin of the species you could say.
