Excerpt from wsj.com
By Eric Metaxas
In 1966 Time magazine ran a cover story asking: Is God Dead?
Many have accepted the cultural narrative that he’s obsolete—that as
science progresses, there is less need for a “God” to explain the
universe. Yet it turns out that the rumors of God’s death were
premature. More amazing is that the relatively recent case for his
existence comes from a surprising place—science itself.
Here’s
the story: The same year Time featured the now-famous headline, the
astronomer
Carl Sagan
announced that there were two important criteria for a planet to
support life: The right kind of star, and a planet the right distance
from that star. Given the roughly octillion—1 followed by 27
zeros—planets in the universe, there should have been about septillion—1
followed by 24 zeros—planets capable of supporting life.
With
such spectacular odds, the Search for Extraterrestrial Intelligence, a
large, expensive collection of private and publicly funded projects
launched in the 1960s, was sure to turn up something soon. Scientists
listened with a vast radio telescopic network for signals that resembled
coded intelligence and were not merely random. But as years passed, the
silence from the rest of the universe was deafening. Congress defunded
SETI in 1993, but the search continues with private funds. As of 2014,
researches have discovered precisely bubkis—0 followed by nothing.
What
happened? As our knowledge of the universe increased, it became clear
that there were far more factors necessary for life than Sagan supposed.
His two parameters grew to 10 and then 20 and then 50, and so the
number of potentially life-supporting planets decreased accordingly. The
number dropped to a few thousand planets and kept on plummeting.
Even
SETI proponents acknowledged the problem.
Peter Schenkel
wrote in a 2006 piece for Skeptical Inquirer magazine: “In light
of new findings and insights, it seems appropriate to put excessive
euphoria to rest . . . . We should quietly admit that the early
estimates . . . may no longer be tenable.”
As factors continued
to be discovered, the number of possible planets hit zero, and kept
going. In other words, the odds turned against any planet in the
universe supporting life, including this one. Probability said that even
we shouldn’t be here.
Today there are more than 200 known
parameters necessary for a planet to support life—every single one of
which must be perfectly met, or the whole thing falls apart. Without a
massive planet like Jupiter nearby, whose gravity will draw away
asteroids, a thousand times as many would hit Earth’s surface. The odds
against life in the universe are simply astonishing.
Yet here we
are, not only existing, but talking about existing. What can account
for it? Can every one of those many parameters have been perfect by
accident? At what point is it fair to admit that science suggests that
we cannot be the result of random forces? Doesn’t assuming that an
intelligence created these perfect conditions require far less faith
than believing that a life-sustaining Earth just happened to beat the
inconceivable odds to come into being?
There’s more. The
fine-tuning necessary for life to exist on a planet is nothing compared
with the fine-tuning required for the universe to exist at all. For
example, astrophysicists now know that the values of the four
fundamental forces—gravity, the electromagnetic force, and the “strong”
and “weak” nuclear forces—were determined less than one millionth of a
second after the big bang. Alter any one value and the universe could
not exist. For instance, if the ratio between the nuclear strong force
and the electromagnetic force had been off by the tiniest fraction of
the tiniest fraction—by even one part in 100,000,000,000,000,000—then no
stars could have ever formed at all. Feel free to gulp.
Multiply
that single parameter by all the other necessary conditions, and the
odds against the universe existing are so heart-stoppingly astronomical
that the notion that it all “just happened” defies common sense. It
would be like tossing a coin and having it come up heads 10 quintillion
times in a row. Really?
Fred Hoyle,
the astronomer who coined the term “big bang,” said that his
atheism was “greatly shaken” at these developments. He later wrote that
“a common-sense interpretation of the facts suggests that a
super-intellect has monkeyed with the physics, as well as with chemistry
and biology . . . . The numbers one calculates from the facts seem to
me so overwhelming as to put this conclusion almost beyond question.”
Theoretical
physicist
Paul Davies
has said that “the appearance of design is overwhelming” and
Oxford professor
Dr. John Lennox
has said “the more we get to know about our universe, the more
the hypothesis that there is a Creator . . . gains in credibility as the
best explanation of why we are here.”
The greatest miracle of
all time, without any close seconds, is the universe. It is the miracle
of all miracles, one that ineluctably points with the combined
brightness of every star to something—or Someone—beyond itself.
