be flat

it is my understanding that residual radiation from the most recent universal separation incident (big bang) exists in a frequency nearly equivalent to a b-flat, and that the deepest "note" ever detected is a b-flat emanating from a supermassive black hole (57 octaves below a middle C). And so, as I listen (and who wouldn't)...closely, intently...and it is faint, almost imperceptable, but I think I hear it...wait, listen....there it is...the universe humming, humming a "b flat," hummmmm. shhhh........no, no, wait, goddamn it, i am pretty sure that is the hum from my idiot neighbor's generator. i wish it were easier. i think.
