Although these waves are not acoustic pressure waves (like ordinary sound waves in air)—but are theorized, rather, as squeezes and stretches in the very stuff of space-time—their frequencies, captured by detection instruments, coincidentally map onto the human auditory range (though, by the time they arrive at Earth, at vanishingly low amplitudes, one one-thousandth the diameter of a proton, much diminished from their initial, gargantuan sizes).2 Scientists like Hughes have employed acoustic analogies to anticipate what gravitational waves might sound like to a detector, and have been creating audio simulations of possible discovery events.	cache/ca-2829.htm	txt/ca-2829.txt
