Sixty Billion Stars. And No Aliens? What Now?

Are we approaching a crisis of faith in ET?

At Universe Today, Matt Williams asks if it is time to update the Drake Equation, by which you could settle — in your own mind — how likely the aliens are. It began to be developed nearly sixty years ago at a conference at the National Radio Astronomy Observatory in Green Bank, West Virginia. And everyone took for granted that we would be hearing from the aliens soon. That was the basis of Search for Extraterrestrial Intelligence (SETI) — keeping the hope alive. Rather than being an actual means for quantifying the number of intelligent species in our galaxy, the purpose of the equation was meant to frame the discussion on SETI. In addition to encapsulating the challenges facing scientists, Read More ›

The Search for Extraterrestrial Life Gets an Update

The universe appears fine-tuned for life to a dramatic degree; it’s at least reasonable to think it’s out there

California Institute of Technology, NASA’s Jet Propulsion Laboratory and Santiago High School are updating the famous Drake Equation (1961): Over the span of human history, many have wondered if life exists on other planets—intelligent or otherwise. As new tools have been applied to the question, many space scientists have become convinced that the likelihood of extraterrestrial civilizations developing seems more probable than not given all that has been learned. As other exoplanet systems have been found, many circling stars very similar to our sun, it has become difficult to find anything unique about our own planet to justify a belief that Earth alone ever produced life. In this new effort, the researchers have expanded on research done by Frank Drake Read More ›

Does the Slow Pace of Evolution Mean That ET Life Is Rare?

That’s the contention in a recent paper by astrobiologists at Oxford’s Future of Humanity Institute

In a new paper, researchers affiliated with Oxford’s Future of Humanity Institute use the assumptions we make about the evolution of life on Earth to estimate the likelihood of it happening the same way elsewhere. And the numbers do not look good. As a science writer puts it: There are countless naturally occurring, but extremely lucky ways in which Earth is special, sheltered, protected, and encouraged to have evolved life. And some key moments of emerging life seem much more likely than others, based on what really did happen. Caroline Delbert, “Intelligent Life Really Can’t Exist Anywhere Else” at Popular Mechanics In the paper, the Oxford group concludes, It took approximately 4.5 billion years for a series of evolutionary transitions Read More ›

Twenty Years on, Aliens Still Cause Global Warming

Over the years, the Jurassic Park creator observed, science has drifted from its foundation as an objective search for truth toward political power games

In 2003, author and filmmaker Michael Crichton (1942–2008), best known for Jurassic Park, made a now-famous speech at Caltech, titled “Aliens Cause Global Warming.” The title was humorous but the content was serious. He was not addressing some strange theory of global warming; he was warning about the politicization of science. Crichton (left, in 2002, courtesy Jon Chase, Harvard CC 3.0), noted that, over the years, science has drifted away from its foundation as an objective search for truth and given itself over to political power games. The first time that he witnessed that was with the famous Drake Equation, used to turn SETI speculations about space aliens into a science. The Drake equation was a series of probabilities multiplied Read More ›

Is Intelligence Common or Rare in the Universe?

A recent analysis says that life is common but intelligence not so much. Let’s explore the reasoning

We really don't know anything about life elsewhere in the universe so even university-trained scientists often try to WISH it into existence.
