Alien Civilizations: Have we Found One?
#1
I'm a huge Science, as well as a Fiction fan, and have been since the late 50s, as a young teenager in Alaska.  But it wasn't until the 60s that I really got seriously into the genre.  I cut my teeth on the likes of H. Beam Piper, Isaac Asimov, Robert H. Heinlein, Poul Anderson, Brian Aldis(Starship), and all of the Ace book series I could get my hands on.  So I have always been inclined favorably toward the existence of alien civilizations.  

Anyway, I was going through some of the Ted Talks presentations when I happened to come across this presenter, who was discussing a relatively new star that she claimed was "The most mysterious star in the universe".  Her name is Dr. Tabetha Boyajian, who is an astrophysicist at LSU.  She was talking about This Mysterious Star, KIC 8462852, Tabby's Star named after her, and the subject of alien civilizations came up.  She considers this possibility last on her list, but she stated that it was a true possibility.  Here is the presentation:

The most mysterious star in the universe | Tabetha Boyajian




After watching this, I became real interested in learning about KIC 8462852.  First off, I did a search on line, and there is a vast amount of information about this star.  So I started from the top of the list, and have been working myself down the line.  The possibilities are immense, or...............it could be little or nothing.  And too, the star's distance from us is around 1400 light years away, which would make travel quite problematic.  'Course I have to skip the Japanese articles about this.   S5

Here are a couple of good starters is anyone is interested.

Now, on the serious side there is this recent scientific paper on he very subject. I just saw this yesterday, and its one of my regular sites.  If you go to the 1:50 mark, you will see this latest report on the possibility of Alien civilizations.

Quote:Upper limit on the fraction of alien civilizations that develop communication technology

PDF link-https://arxiv.org/pdf/1908.01335.pdf

(Submitted - August 4, 2019) We re-examine the likelihood for alien civilizations to develop communication technology on the basis of the general assumption that life elsewhere could have a non-carbon chemical foundation. We particularized the discussion to a complex silicon-based biochemistry in a nitrogen solvent, and elaborate on the environment in which such a chemistry is feasible, and if so, on what scales. More concretely, we determine the region outside the habitable zone where such organisms can grow and flourish and after that we study how our findings impact the recently derived upper limit on the fraction of living intelligent species that develop communication technology hbioteci. We also compare this new restriction onhbioteciwith that resulting from the extension of the habitable zone to accommodate subsurface exolife, originating in planets with subsurface (water) oceans.

Perhaps its time to reassess the Drake Equation.
