Extraterrestrial civilizations do not visit us and it is our sun’s fault

Jacob Haqq-Misra and Thomas J. Fauchez believe that extraterrestrial civilizations would seek to expand by K- or M-type dwarf stars.

Enrico Fermi  is the author of a  paradox that bears his name  and that tries to explain why no  extraterrestrial civilization  has made contact with us earthlings. The illusion of knowing if there is another intelligent race has been the result of studies and stories since ancient times, but so far  we have no indication that we are together in the universe.  The reason, according to a new study, is very clear:  the problem is our Sun.

Using the  Drake equation as a basis ,  Jacob Haqq-Misra  and  Thomas J. Fauchez  are the authors of this  new hypothesis  that was published in  The Astronomical Journal.  The same part from the assumption that technologically advanced civilizations  travel from one star to another  in search of  expansion  or survival of their race. But on that journey there may be the possibility that there are solar systems that simply  are not attractive to them.

Drake’s equation

It should be noted that the Drake equation is an attempt to  calculate the number of civilizations that could exist in our galaxy  based on the rate of star formation, how many of those stars host planets around them, and how many of those planets could be in one zone. habitable.

Jacob Haqq-Misra and Thomas J. Fauchez believe that these civilizations would seek to expand by  type K or M dwarf stars , since they are much longer-  lived stars , something that the Drake equation omits in its formula.

Our Sun is a  star of spectral type G2 and luminosity V.  For its part, type K stars are orange dwarfs and type M are red dwarfs. Both types have the characteristic that they are less luminous than our Sun, but they can still be  habitable.  And there is something important: they are stars that last much longer in their main sequence and are  more stable than our Sun.

Our Sun is  4.6 billion years old  and its main sequence will still last another  10 billion years , according to expert calculations. However, it is estimated that in a few billion years its  expansion will begin  and with it  it will end life  as we know it on Earth.

In contrast, K-type stars  remain stable for periods of between 25 and 80 billion years.  This would make any civilization looking for a place to live long-term choose these systems over our galaxy.

“But we don’t know much more about whether or not such galactic-scale expansion would be usual or desirable for technological civilizations in general,” the authors of this new study write.
