The latest way I heard of to communicate with aliens is via thumbnail sized satellites that can move through space more quickly than anything we have tried before.
It seems that these mini satellites might go out and return information within decades rather than light years. So perhaps some of you younger folk might receive messages.
But maybe some of us will receive or have received messages before that. Maybe when we tried to tell others about these messages, no one believed us. Or maybe we were sworn to silence. Or maybe some of us just imagined communications.
I think that if even we imagine an event like a communication from other worlds or galaxies it either happened or it will happen. And since we are not sure about the distinction between past, present and future either, we cannot tell where or when. Who knows what has happened or is happening or will happen. But in my view, whatever we eventually may learn, it is almost certain that intelligent life exists out there.
Read New New York, 3000 Years Later to consider interaction with beings in other universes.
