Life not likely

While there is much cause for excitement in the discovery of planet 581 c announced in The Bee on April 25, the exuberance of many in the science community may be misleading. Life is not ubiquitous throughout the universe or in our own neighborhood and is very unlikely to be found on 581 c.

For any life (not just life as we know it) to exist anywhere in the universe requires that hundreds of extremely fined-tuned parameters are met, such as parent-star position in the galaxy, star luminosity, planetary gravitational, tidal and rotational forces, and of course a stable water cycle, to name just a few.

When all of these factors are considered, far less than a trillionth of a trillionth of a percent of all stars in the entire universe will have a planet capable of sustaining life. A partial list of these parameters may be found at www.reasons.org.
