This had better not be an infinite universe, because if it is, then it contains everything. EVERYTHING. Even a universe that is not infinite.
All possibilities would become realities, given infinite time and space:
    A planet full of failed carpet cleaning businesses
    Another planet full of the people who sold the machines to the carpet cleaners who ran the businesses into the ground
    An entire galaxy full of the psychiatrists to the parking meter attendants who ticketed the veteranarians of the sickly dogs of the former owners of the few customers of the failed carpet cleaning businesses
And so on, ad suicidem.
