SETI-SETR
If we detect a signal from an extra-terrestrial civilization, it will come from a society far older than ours. What will they know? And what will they believe?
Extra-Solar Religion and Science
The SETR book: how religion and science might have co-evolved in civilizations millions of years older than ours, and what their message could mean for our own beliefs.
Numbers of Civilizations
Working the Drake equation forward: estimates of how many communicating civilizations exist now, and how many came before us.
Eternity: a Theory of Everything
A speculative physics essay: relativity, gravity, waves, particles, and cosmology viewed from outside spacetime.
The Drake Equation
The classic calculation of detectable civilizations, its terms, the distances involved, and what zero results so far actually tell us.
SETI is the Search for Extra-Terrestrial Intelligence. SETR is its companion question: the Search for Extra-Terrestrial Religion. This site, written by Rex Pay (author of the Humanistic Texts anthology), asks what happens to belief systems when a civilization grows very old, and how first contact might change ours.
