Normally, I'm not one for Astronomical documentation, mainly cause I don't have the attention span for it.
What happens if any E.T civ. doesn't use the same frequencies that we use for communication. I mean the endurance and strength of radio signals could
go for quite a ways. The odds of an E.t race blastin their own top 20 hits, or some diplomat extremists making some speech could be good, considering
we did it.
However, any E.t that capable of interstellar travel with easy, would be using Ftl communications. We couldn't pick it up, or maybe even notice it.
While they could pick any signal we sent.
Better off wishing on a shooting star.
Well from what I've read, the hydrogen band isn't the greatest band to signal on. Interstellar hydrogen absorbs the radio waves and diffuses the
signal. You want something with minimal interference and maximum bandwidth - optical for instance. Optical SETI is relatively recent, and I haven't
heard much from it.
IMHO, I think we should look towards SETA (bracewell probes) and optics - for laser and for megastructures/astroengineering. The Benford beacon stuff
seems to have really caused some waves in the field, and at least once article that I read suggested we'd already run into transient radio bursts
from where Benford suggested we look. I'm curious if anyone has recorded one of these, or is watching for them with amatuer equipment. Signal
analysis would make for a fun hobby.
A kickstarter cubesat could do some nifty work.
