What if they cannot hear themselves think?

By Lynne Cory

What if we are the noisiest planet in the multi-verse?  What if our millions of cars, trains, buses, airplanes and jets, motorcycles, blaring TVs, loud cellphone conversations, annoying music, jackhammers, chainsaws, etc. make intolerable noise?  What if we are getting noisier as our numbers increase?  What if all of this noise goes out into the stars and irritates the beings in space?
