NASA’s Perseverance Rover just found Martian rocks rich in minerals tied to microbial life. Exciting—yet without a sample-return and proof of independent origin, this points more to panspermia than proof of life beyond Earth.

I joined John Michael Godier on Event Horizon to discuss my new book Reinventing SETI—from the “Dark Forest” hypothesis to the risks of messaging ET and bold new strategies for the search.

NASA’s Perseverance rover found organic molecules in Jezero Crater—once a Martian lakebed. A rock dubbed “Leopard Spots” may even show hints of past microbial life. Proof awaits sample return to Earth.

Had a great time talking with ‪@ryansprague.bsky.social on Somewhere in the Skies about reinventing SETI, alien probes, and why the search for ET needs a bold new vision 👽🛸. Check out the full conversation here: shows.acast.com/somewhere-in....

What if the reason we haven’t heard from ET is because they're waiting for us to do the heavy lifting? Fair trade might mean they’re sending signals too faint for our current tech—read why at johngertz.com/blog.

In my forthcoming book, I list the places where I think we would be most likely to find alien robotic probes within our Solar System. But how do we search for these probes?

Too much of the ET debate has veered from science into worship. I unpack that in my latest blog post: johngertz.com/blog/f/the-c...

The Cult of ET Worship

On November 15, the NYT published an op-ed by Douglas Vakoch espousing the perceived benefits of proactively transmitting messages to extraterrestrial intelligent (ET) civilizations. Many of us in the...

Uploading the entire internet to ET?
Terrible idea.
Information is the only coin of the realm.
Send Mozart first. Let them ask for the Beatles, Balinese gamelan, and Indian sitar, and then see what they’ve got to trade for it.

In my upcoming book Reinventing SETI, I argue that SETI is the alchemy of our time—real science tools aimed at a dream we can’t yet reach. Until aliens find us (or we find them), we may just be fumbling in the dark. Read more: johngertz.com/blog

SETI needs a rethink. Signals across the stars? Not efficient. Smart civilizations would send probes instead. We need to start looking closer to home. #seti #spaceexploration
