Sending messages to ET - a good idea?
Personally, it gives me the heebiejeebies.
But a group of (of course) Americans is planning to send laser messages to known planets circling nearby stars in an attempt to initiate communication with any technological civilisations there.
If we get a return message, will the invasion fleet be far behind?
Or maybe the first thing we know is when the slavers turn up.
After all, it's what we would do. Human history is not very positive about advanced societies meeting less capable ones.
