Mercurio D Rivera's "Answers from the event horizon" (flash fiction, parallel universe)

Funny exchange between two species - one at about our level of development, other a super advanced civilization from a parallel universe. Former keeps asking questions the later finds silly - in a way that reminds me of William Morrison's "The Sack".

One of the species appears to be human, but I'm not clear which.
