The recent discovery of seventeen billion earth-size planets in our own galaxy, according to an Associated Press article appearing in the Everett Herald on January 8, sounds at first so very impressive as to demolish my skeptical position on the possibility of life in outer space. Especially considering the fact that there are conservatively well over 100 billion galaxies that have existed for almost 13 billion years!
Yet in the final analysis these numbers are woefully inadequate to the task of yielding life by purely naturalistic means. While the newspaper article concedes that not all planets are “potentially habitable,” it does declare that “the sheer number of earth-sized planets is a welcome starting point in the search for worlds like our own.” But this amounts to a gross overstatement. The number of factors that are now understood by the scientific community as a whole to be required in order for advanced life to be viable is becoming increasingly large. Consider the following partial list of the requirements:
Only
3rd generation stars, which are aftermath
of the explosions of previous generations of stars, are capable of producing
“rocky,” that is, solid planets.
Elliptical
or irregular galaxies do not produce 3rd generation stars. Only spiral galaxies (just 6%
of the total galaxies), yield stars capable of producing “rocky” planets.
Spiral
galaxies must be nearly symmetrical, unlike a bicycle tire overrun by a car.
Only
2% of 3rd generation stars produce the
sufficient list of elements for the existence of life.
That
array must include carbon as the basis for life, plus almost the whole range of
naturally occurring elements which our periodic table documents.
Uniquely, our own sun is the after-product of two nearly simultaneous
explosions of neighboring supernovas.
For
stability purposes alone, the parent star of a life-friendly planet must be
just the right size. Either a little too large or too little and that sun
will be too erratic to initiate and maintain advanced life. Our own sun
is the most stable star astronomers have detected.
For
the same reason as above, the parent star must be just the right age.
To
be continued...
We do have to consider that other life forms that God might have chosen to create may not require the same environment to thrive that we do.
