Is there intelligent life beyond Earth?
It’s the ultimate question, isn’t it? It’s also the subject of this week’s It’s Okay To Be Smart. I think you’re gonna like this one.
As we continue to tally Earth-like planets in our galaxy, we are closer than ever to being able to answer mankind’s ultimate question of existence: Are we the lone intelligent, curious, communicative life form in the universe?
I don’t know the answer to that. But here’s the other questions I tackle this week: We don’t have telescopes (yet) capable of directly imaging far-off worlds to scan them for signatures of living chemistry, but if we did, what would we look for? If we can’t see these worlds, can we listen for them? How are we advertising ourselves to the galaxy? Is the expiration date for life on Earth sooner than we think? What can we do about it?
Inside, you’ll find a heavy dose of extraterrestrial longing, some research done by Carl Sagan, a whole lot about the letter “L”, me doing my best “death metal” voice, and a really special treat from Ray Bradbury at the end.
Enjoy, and stay curious!
