Signals — Lawrence Frederick

Earth sends millions of radio signals out into space. Do we know who is listening?.

These radio signals travel at the speed of light and by now those first signals have encompassed the realms of many nearby stars. No one really knows who might listen to those signals.

The science fiction short story Signals flirts with cyberpunk themes as it explores pre-contact humanity with extra-solar worlds and the alien species that inhabit them. Earth is advertising its existence. Do we really know to whom we are marketing our presence?
