SETI, METI… and Assessing Risk like Adults

November 12, 2013

David Brin is a familiar name to science fiction readers worldwide, the award-winning author of the highly regarded ‘uplift’ novels that include Startide Rising (1983), The Uplift War (1987) and Brightness Reef (1995). Among his numerous other titles are The Postman (1985), Kiln People (2002) and Existence (2012). But Brin is also known as a […]

James Benford: Comments on METI

November 11, 2013

Pardon this extended introduction to Jim Benford’s response to Nick Nielsen’s Friday essay, but it comes at a serendipitous time. Jim’s recent online work has reminded me that we in the interstellar community need to work to see that as many resources as possible are made available online. In the absence of specialized bibliographies, useful […]

SETI, METI, and Existential Risk

November 8, 2013

To broadcast or not to broadcast? The debate over sending intentional signals to other stars continues to simmer even as various messages are sent, with no international policy in place to govern them. Writer Nick Nielsen looks at METI afresh today, placing it in the context of existential risk and pondering the implications of what […]

The Pros and Cons of METI

May 6, 2011

Tau Zero journalist Larry Klaes has been fascinated by SETI — and its offshoot METI (Messaging to Extraterrestrial Intelligence) — for a long time now. Here he steps back to look at METI in context, offering up an examination of the advantages of sending signals to the stars and the offsetting risks. We’ve looked at […]

Regarding METI and SETI Motives

September 22, 2009

by James Benford I first talked to Jim Benford back in 2003, discussing his work (wih brother Gregory) on microwave beam propulsion. He had already run experiments at the Jet Propulsion Laboratory demonstrating acceleration on a lightsail using these techniques, and was then hoping to run an experiment on The Planetary Society’s ill-fated Cosmos 1. […]

The Why of METI and SETI

September 18, 2009

by Larry Klaes About a decade ago while attending a SETI conference, I was listening to a researcher give a talk about detecting messages from other galaxies such as the giant elliptical galaxy Messier 87 and the immense Virgo galactic cluster it resides in. Since M87 is about 60 million light years from the Milky […]

METI: Learning from Efficient Beacons

October 30, 2008

If we want to consider how to pick up transmissions from a distant civilization, it pays to consider the most effective strategies for building interstellar beacons here on Earth. This is the method James, Gregory and Dominic Benford have used in twin papers on SETI/METI issues, papers that should be read in conjunction since the […]

What Io Can Teach Us

August 14, 2014

Io doesn’t come into play very much on Centauri Dreams, probably because of the high astrobiological interest in the other Galilean satellites of Jupiter — Europa, Callisto and Ganymede — each of which may have an internal ocean and one, Europa, a surface that occasionally releases material from below. Io seems like a volcanic hell, […]

NIAC: An Orbiting Rainbow

August 8, 2014

Remember Robert Forward’s beamed sail concepts designed for travel to another star? Forward was the master of thinking big, addressing questions of physics which, once solved, left it up to the engineers to actually build the enormous infrastructure needed. Thus his crewed mission to Epsilon Eridani, which would demand not only a large power station […]

Interstellar Booklist

July 26, 2014

Many of the books listed below are ones that I used in preparing my 2005 book Centauri Dreams: Imagining and Planning Interstellar Exploration. But in the time since, I’ve added a number of more recent titles. I’m hoping Heath Rezabek’s curation project will reveal other books that may be useful as we flesh out the […]
