Not all stars are equal when it comes to
supporting life. Our Sun is:
- Stable (not prone to violent
flares)
- Long-lived (capable of billions of
years of steady output)
- The right size (warms and lights,
but does not overwhelm.)
Many stars burn too fast, fluctuate too
much, or emit dangerous radiation. But
the Sun provides a long, steady energy
source that allows complex systems to
develop and thrive.
Our planet is fine-tuned for life.
Earth’s habitability depends on a
remarkable convergence of planetary
conditions.
Earth sits in the Sun’s habitable zone,
where liquid water can exist. Its orbit
is said to be nearly circular, avoiding
extreme temperature swings. Slightly
closer and the Earth would suffer from a
runaway greenhouse effect. Slightly
farther and the Earth would be global
ice.
Earth is massive enough to hold an
atmosphere, but not so massive that it
becomes a gas giant. Just the right
gravity holds air and water in place,
while still allowing complex chemistry
to occur at the surface.
Scientists say Earth’s unusually large
Moon stabilizes our axial tilt,
preventing chaotic climate swings. It
also drives tides, and offers benefits
we still do not fully understand.
Earth is not just positioned correctly -
it is geologically alive. Moving plate
tectonics recycle nutrients, regulate
carbon dioxide, and prevent Earth from
becoming either a frozen wasteland or a
runaway greenhouse.
Our atmosphere is transparent to visible
light (for photosynthesis) but blocks
much harmful radiation. Its composition
is finely balanced for respiration and
climate regulation.
Earth’s magnetic field shields the
surface from deadly solar radiation and
prevents atmospheric erosion.
What I’ve laid out here is only an
overview of a few of the factors that go
into fine-tuning of the universe. There
are so many more. The key insight here
though, is this: Fine-tuning is not just
‘one knob’ - one dial set correctly -
it is many, set correctly to operate as
a life-support system. It is many
independent dials, governing different
physical processes, all set within
narrow life-supporting ranges -
simultaneously. Change one, and all life
dies. This cumulative nature is what
gives fine-tuning its force.
How should we interpret this? Scientists
agree on the facts of fine-tuning. The
debate is about interpretation.
Some say this is simply a brute fact:
the universe just happens to be this way
by dumb chance. Since this conclusion
defies logic (and math) others appeal to
speculative multiverse theories,
suggesting many universes exist and we
inhabit a lucky one. Just a bigger dumb
chance argument.
The fact is, creating a life-support
system to keep people alive in space
doesn’t just happen on its own. A lot of
planning and work has gone into the
issue of life support for Astronauts,
producing elaborate systems that do not
work nearly as well as our Earth
supports all of us. Nobody would suggest
those life-support systems for
Astronauts just happened by chance.
Surely, it is obvious that fine-tuning
of the universe, and our corner of it,
is intentional, and if intentional, it
was our Creator who did the fine-tuning
that is right now keeping all of us
alive. Let us praise God!
“Worthy are you, our Lord and God,
the Holy One, to receive the glory,
the honor, and the power, for you
created all things, and because of
your desire they existed, and were
created!” Revelation 4:11
The existence of our Creator is a
fact too big to ignore. At the
Areopagus in Athens the apostle,
Paul, made his case about this to
Greek philosophers of his day,
saying of our Creator:
He made from one blood every nation
of men to dwell on all the surface
of the earth, having determined
appointed seasons, and the
boundaries of their dwellings, that
they should seek the Lord, if
perhaps they might reach out for him
and find him, though he is not far
from each one of us. For in him we
live, and move, and have our being.
As some of your own poets have said,
"For we are also his offspring." Acts 17:26-28
This is another aspect of fine-tuning
that is seldom mentioned. He has
fine-tuned His universe in a way that
reaches out to you, to know Him, if only
you seek for Him. Here at Tsiyon we are
glad to pass along what we have come to
know from Him. I invite you to join us
for our next live stream, to hear more.
That's tonight at 8
Central, at
Tsiyon.Net - and other
popular video platforms. "For
in him we live, and move, and have
our being." Let's get to know Him
better, together.
In His Name, Eliyahu
