SIGNALS IN THE NOISE
Green Bank Telescope, Green Bank, WV
Country singer Kenny Chesney has a new hit song titled “Noise” lamenting that “in the streets, in the crowds, it ain’t nothing but noise. Just trying to be heard in all this noise.” Emily Smith in her new book on The Power of Meaning notes that “we humans have a primal desire to impose order on disorder—to find the signal in the noise. We see faces in the clouds, hear footsteps in the rustling of leaves, and detect conspiracies in unrelated events. We are constantly taking pieces of information and adding a layer of meaning to them; we couldn’t function otherwise.”
I like the analogy of seeking the signal in the noise. It reminded me of the ongoing scientific quest to detect intelligent extraterrestrial life in all the electromagnetic radiation noise in the universe and beyond. Phenomena such as gamma-ray high energy bursts originate throughout the universe and are candidates for extraterrestrial communication. Many folks aren’t even aware of the very sophisticated technology that’s been developed and employed around the world such as the Green Bank Observatory in a remote West Virginia woodland that listens to the noise in outer space. Then the challenge is to attempt detection of some possible signal in the noise indicating a transmission from civilizations on other worlds.
Our modern world is indeed contaminated with noise from our activities including all manner of transportation and electronic devices such as smart phones and 24/7 cable television. This makes it very difficult for us humans to place life on pause, jump off the merry-go-round and find a place of solitude. The Psalmist knew this when he wrote in chapter 46 verse 10, “Be still and know that I am God.” For our own sanity, we really need to have times and places of solitude so that we can listen to our creator and sort out the signals in the noise that can help us maintain order in our lives.
