Q: In a sense, any microphone is picking up sounds from the past, due to the speed of sound. This is similar to what you mentioned with radio telescopes.\n\nThe main differences are 1) velocity -- light moves at about 1 foot per nanosecond while sound moves around 1 foot per 1/1000 second, and 2) that sound moving though a medium diffuses quite rapidly.
