Yikes!!! Only 22 light years away. In that case we should be on the lookout for very noisy reruns of I Love Lucy beaming to us from space.
Or Double Yikes. They could have been listening to our radio broadcasts from the 30’s or earlier and already be here with their just sub-luminal drive spaceships. Hide your Al Jolson records just for safety’s sake.
What if they are Three Stooges Fans?................
It sort of amusing to think if they are monitoring our TV and Radio signals, they just saw the fall of the Berlin Wall (and good music is still on MTV) as far as they are concerned all of this is just happening "now", even though it's been 22 years for us.
