Hello group,

I have some ideas and questions I wanted to ask, please be kind with
your replies if any as I am new to this group and not sure if this has
been batted around before.

What if we are looking in all the wrong places for a singal from an
Extra-Terrestrial intelligent species?

I've read the article in which sending radio singals across
interstellar distances is just not econemical, and now there is a
growing belief that ET would send a "message in a bottle" instead of
by radio.
My take on this is it's half true, ET is probably launching probes to
different points of interists, but they would be using some kind of
communication method be it Radio, Laser or even Neutrino, to
communicate to the probe from the home planet. This seems realistic as
this what we would most likely do.

Note that the communication system that they use is most likely to be
designed to be a very tight beam. The chance of us being in the beam, in
direct line of sight from the probe to its home planet, is very low.

Note also that the signals from the probe to the planet are likely to be
very much weaker than the command signals from the planet to the probe,
because it's easier to build huge antennae and power stations on home
soil. If the probe has a smaller receiving antenna, the command signals
need to be stronger. That's certainly the way that we always organize
things for interplanetary probes. So perhaps it would be best to target
our searches in exactly the opposite direction from interesting objects.
