Stealing science for a story

[neotoma]

So the other week I was listening to the radio, and up came a story about a new theory about how homing pigeons may use 'sound maps' to navigate. This is going right into the Big Bang -- I'd already thought the angels use infrasound to communicate over long distances, but the idea that they use the sounds created by seismic energy from deflected deep ocean sounds to orientate themselves is just too fun to resist.

Yeah, I'm such a nerd.

Otoh, this explains how angels communicate, and it will also explain how the traditionalist/isolationist communities of angels hide themselves. They simply sing at wavelengths that don't travel as far as other angels, so they've limited the distance their communications travels. Of course, the research centers probably have listening stations in those areas specifically to pick up the infrasound, but it probably takes the researchers a lot of time to go through and translate the songs, even with the help of the friendly angels, so they're behind on what's going on in the isolationist communities.

Also, I'll have to remember this because it might eventually be a neat thing to put in an original SF story...
