How would we build galactic-scale beacons to attract the attention of extraterrestrials?

Posted on Categories Science

Back in the day, I ran the old SETI Online program on my computer (over 56k dial-up!) to help to try to detect signals made by another civilisation. Best as I know, we haven’t found ET yet, but until today I’ve never even considered what effort it would take us to send such a beacon out to the galaxy.

This interesting presentation by James Benford on Youtube (paper) has a bunch of thought-provoking ideas about this.
