The list continues from my previous blog of those
physical requirements that allow a planet to be habitable for
intelligent life:
To
shield harmful radiation from the Galaxy core, our sun must be shielded from
the core by gas clouds.
The
sun must be neither too close to the core and its harmful radiation…
...nor too far
from the core, which would prevent the reception of radiation that is necessary
for life’s existence.
Our
sun must lie outside the galaxy arms, though not too far from them.
Our
sun must orbit the galaxy core at the same rate as both the neighboring arms
and stars so that collisions will be avoided.
It
must not lie above (or below) the orbital plane in such a way that radiation
from the galaxy core would hit it directly (much like getting hit by a squirt
gun while stealing a peak over the top of your friend’s fence).
For
gravitational stability purposes our sun must be a single star. 80% of known stars exist as doubles in
gravitational relationship with either other.
It
is required that we be neither too far from, nor too close to, (the variation
allowable within just a few percentage points).
It
is necessary that our planet have very close to a 365 day rotation cycle.
For
stability purposes it is necessary that there are neighboring planets revolving
around our sun in the same plane as our own planet.
For
our protection from harmful debris we need a “Jupiter” kind of planet of such a
size that its gravitational power draws harmful asteroids and meteors away from
us and into its own sphere.
For
both our stability as a planet and for our tidal cycle, we need our moon to be
just the size it is and revolving around our planet at its current duration.
For
gravitational reasons, our moon must remain at its current distance from the
earth.
For
the proper flow of the seasons we need our rotational tilt as a planet to be
just what it is, even as it must remain at the speed that it is.
For
gravitational reasons our planet must be just the size it actually is, so that
it allows water vapor (molecular weight 18) while allowing methane (16) and
ammonia (17) to dissipate.
It
is necessary that a habitable planet have a radioactive core which produces
necessary minerals underground…
...and
plate tectonics for the creation both of continents and mountains…
and
also earthquakes for the continual recycling of necessary minerals below ground
back up onto the surface of the earth. Apart from plate tectonics a
planet is uninhabitable for life.
A
magnetic core is required that produces a shield capable of protecting earth
from the sun’s harmful radiation.
We have just begun to scratch the surface of
the matter. The point is, the existence of a planet that is capable of
being a wonderful home for intelligent life is a matter greater than throwing a
couple of factors together. The scientific community has gathered a total
of at least 75 separate requirements for life to exist anywhere in the
universe. The odds in favor of the occurrence of nearly every one of
these is very small since they lie within an extremely narrow range of
acceptable limits. The estimated odds for each and every factor (ponder
this on your own) all multiply on every
one of the other factors. Astronomer Dr. Hugh Ross has noted that
when all of these realities are factored together the result is “Much less than one chance in a hundred
thousand, trillion, trillion, trillion, trillion, trillion, exists that even
one such planet would occur anywhere in the universe.” For your
