Planet better than Earth claimed within reach

From MacGregor Campbell at at New Scientist:

We are used to thinking small when it comes to alien life. Our list of living worlds has a sole data point, Earth, and even our convivial planet seems to have been a tricky place for life to get started. How could we expect more than a self-replicating bag of biomolecules anywhere else?

That might be too lofty a view of Earth. After all, huge areas of our planet, including the poles and deserts, are rather barren. And whole epochs of time were inhospitable to life. More.

So, of course, “There should be worlds out there so balmy they make Earth look stale, and there are signs of one just four light years away.”

File with: New Scientist astounds: Information is physical The last time this idea whistled through, couple years back, the alleged substance was called perceptronium

Keep in mind that many “sciencey” people actually believe and set store by this kind of stuff. It gives meaning to their lives. And they help shape public policy too.

How do we grapple with the idea that ET might not be out there?

Remember when they supposedly found a planet a few years back and we were told that there was a 100% chance of life being found on that planet? Gliese 581g was what they named it, I think. Space.com had beautiful pictures of the artist's conception of the planet(how accurate do you think they are?) and ran this headline:"Odds of Life on Newfound Earth-Size Planet '100 Percent,' Astronomer Says" http://www.space.com/9225-odds-life-newfound-earth-size-planet-100-percent-astronomer.html However, on May 4, 2016, they ran these headlines: "Gliese 581g: Potentially Habitable Planet — If It Exists" And the article begins with these words: "Gliese 581g is an extra-solar planet candidate within a planetary system that is only 20 light-years from Earth, but at this point it is highly doubted to exist. First announced in 2010 as a planet close to Earth's mass in the habitable zone of its host star, the exoplanet has come under scrutiny as other research teams cast doubts on its discovery." http://www.space.com/23821-gliese-581g.html#sthash.6xOfxaFe.dpuf Anyway, we don't hear the 100% claim anymore which is good, but they are still publishing about this imaginary planet complete with imaginary pictures of it. What a bunch of hooey! tjguy
