is there anybody out there?

stray noises in the night elicit fears
when mind's deprived of input from our sight
we're ill-equipped to navigate by ears
scenarios abound that might be right
bats conjure up reality from sound
as tangible to them as light to us
their construct rests on just as solid ground
despite a wholly different stimulus
if Yoda learned to read gravity waves
his information stream cannot be blocked
abroad by day or in stygian caves
his data keep on coming 'round the clock
if all converge on one ontology
it's more than anyone's equipped to see
