Greetings, E.T. (Please Don’t Murder Us.) - The New York Times

Steven Johnson dives deep into the METI project, starting with the Arecibo message and covering Lincos, the Drake equation, and the Fermi paradox.

He also wrote about what he left out of the article and mentions that he’s writing a book on long-term decision making.

In a sense, the METI debate runs parallel to other existential decisions that we will be confronting in the coming decades, as our technological and scientific powers increase. Should we create superintelligent machines that exceed our own intellectual capabilities by such a wide margin that we cease to understand how their intelligence works? Should we ‘‘cure’’ death, as many technologists are proposing? Like METI, these are potentially among the most momentous decisions human beings will ever make, and yet the number of people actively participating in those decisions — or even aware such decisions are being made — is minuscule.

SETI: A Networked Galaxy?

A fascinating guest post by Brian McConnell on Centauri Dreams: what if there’s a galactic equivalent to the internet, allowing civilisations to communicate with a system analogous to packet switching.

Unfortunately this kind of focussed signalling would be hard to detect. But on the other hand, it could explain the Fermi paradox.

Asteroid Day

This is an awareness project I can get behind: a Clarke-like Project Spaceguard to protect the Earth from asteroid collisions. This campaign will focus awareness of this issue on one single day…

Now if only the front page of this website actually said when that day will be.

Update: And now it does.
