The Chirp Heard Across the Universe - The New York Times

The Chirp Heard Across the Universe - The New York Times:



"The faint chirp detected by what must be two of the largest and most sensitive microphones ever made — a brief, rising tone from gravitational waves generated by an immeasurably powerful collision of two black holes a billion years ago — has engendered a number of articles about why we should concern ourselves, and by extension dedicate so many resources, to exploring an event so distant in time and space. Various justifications have been offered, from lists of the practical benefits of past discoveries that seemed useless when they were made, to the metaphysical notion that the better we understand our universe, the better we understand ourselves."
