Resumen de Right to silence
Battersby explains how radio astromers adopt mobile phones, GPS receivers, CCTVs wireless broadband connections and all manner of other stuff, fracturing the once-pristine airwaves into a crazy cacophony. Harvey Liszt works at the US National Radio Astronomy Observatory in Virginia, and he knows the problems this causes. His kind need pin-drop quiet to detect emissions from across the cosmos, produced by interstellar molecules that might be early stages in the emergence of life, or clouds of hydrogen that will soon form stars, or giant galaxies where black holes generate plumes of hot gas.
