The data goes into a wormhole, much similar to the one that splits up your pairs of socks in the dryer, and the data wormhole simply sucks it into another universe. No need to worry about the collapse of our universe because of /dev/null BUT...Piping all that data to /dev/null MAY destroy the universe that keeps sending flying saucers to the houses of Art Bell fans in places like Lockjaw, Kentucky or Moose Turd, Montana... jim -- ET has one helluva sense of humor!
