Aww, no alien empires yet

I don't think we are that detectable. Besides our emissions have been declining ,because of more efficient communication equipment, during last two decades.
What I am worried about though is sending messages out. Up to this point were all such attempts pretty much meaningless. Short, low powered, poorly targeted transmissions, more symbolic than anything else but, if we target some specific place where we know large scale civilization is present...

That could end badly.
