Dual Universe: Eternity | Spacetime

There may be billions of planets like ours in the universe. But we have no evidence of a civilization on any of them. There were 6,500 million years for other civilizations to appear in our Galaxy before we evolved. Are civilizations so unstable they last less than 100 millennia? Do they destroy their planet by wars and depletion of resources? To avoid this fate, we need to develop a global world view aimed at protecting our planet. I suggest one contribution to this would be reconciliation of science and religion, based on recognizing that eternity and spacetime form a dual universe that provides a joint spiritual and material reality.

Extraterrestrial Civilizations

Finding an extraterrestrial civilizations would tell us we are not alone in the Galaxy. It would show us that intelligent life can survive the many threats it faces, that complexity is not a liability, and that the universe not devoted solely the habitation of single-celled organisms. Our search starts with an estimate of the probability of there being such civilization and whether they might be within range for communication.

Extra-Solar Planets

One approach of in our search for civilizations beyond the solar system is to scan the skies for evidence of planets capable of supporting life. With ground-based and space-based telescopes we have found many  exoplanets circling stars beyond the sun. We recognize that if such a planet has evolved a civilization it may not decide to broadcast its presence. We therefore look for clues in its atmosphere that might indicate the presence of life and intelligence [More . . .]

Picture of Galaxy

In its initial mission the NASA Kepler spacecraft has detected  4,747 planets in its initial scan of 156,000 stars in a small region of the Cygnus and Lyra constellations in the Milky Way galaxy. Of these, 297 are within the habitable zone of their star. As there are over 200 billion stars in our galaxy, this initial scan of a small region suggests that the galaxy may contain at least 50 billion planets. Of these, millions may be in the habitable zone around their star. (Photo courtesy NASA Kepler Mission/ Carter Roberts)

Extraterrestrial Intelligence:

We recognize that some of the planets in our Milky Way galaxy may support civilizations that have advanced well beyond our own stage of development. This has led to a surge in interest in detecting whether such civilizations may be broadcasting their presence. Under an effort referred to as SETI (the Search for Extraterrestrial Intelligence), the main technique is examination of radio waves or light from outer space for signs of intelligent communications.  [More . . .]

Religion:

On Earth many transmissions are broadcast by religious groups, and religion is both a stabilizing feature of individual civilizations and a source of conflict between civilizations. We should therefore be prepared for religious content in SETI , which may throw light on how science and religion come to terms in in achieving the stability required for an advanced civilization.  [More . . .]

Humanism:

Appreciation of the variety of thought on a planet and how it seeks achievement of a stable society can be gained by exploring the many cultures on our own planet. These contributed to the development of the Universal Declaration of Human Rights. An equivalent declaration may have been appeared in other planetary civilizations. A summary of our own experience is provided by Humanistic Texts .
