hi nathaniel (& scott), yes i'm familiar with the wikipedia art project :)
i don't really know that much about frequencies, but i'm aware of theories that attribute bee colony collapse in part to the increase in electromagnetic frequencies bouncing around the place; & i know people who believe they are also sensitive to this kind of interference. it's easy to dismiss it because it's invisible. (& if only i had an extra 24 hours in the day i would have time to learn more about it all ... ) what about interference with the aliens' own navigation & communication systems? do you know what kinds of systems they might have & how your signal will be received when it arrives somewhere? h : ) On 12/05/12 2:22 PM, Nathaniel Stern wrote: > Hi Helen: > > Thanks for your interest in our work.
