AGE OF THE EARTH:
Age-measure of Earth uranium depends on general radio-decay
rate stability over many billion years, during which the universe estimably expanded
(eight times its volume in 4.5 billion years); And the cosmic background neutrino flux
of all energies is less calculable, depending on cosmic gravitational-closure curvature
and cycle-time, initial [post-bang] neutrino density, supernovae neutrino generation
rates and post-nova mass-attrition rates by galactic "dark matter" hordes of rogue neutron stars and black holes, and black-hole population
neutrino-attrition rates. Elastic neutrino-nuclear collision energies prompt nucleon,
alpha and beta tunneling,- and affect the total radio-decay rates: the Earth may yet be
decidedly younger by half. (*)
* (The cosmic background radiation temperature also dropped by that same factor from
24°K, to below 3°K today.)
BIOLOGICAL-HABITABLE TIME: One billion years.
The existence of water oceans is almost as old as the [overestimated] 4.5 billion years
of the Earth's presence in the solar system, -(as soon as water was available; much has
been suggested attributed to later lunar comet hordes)- as the depth of ocean even atop
magma glowing white hot, is all but the top 800 meters (remaining as superheated vapor
above), and the total-average depth of ocean on Earth was -about- 2600 meters ...
leaving 1800 meters of superheated water scouring its early-ocean seabottom of
chemicals ... but it would have been much too hot for even today's undersea vent-worms.
Pure water is a good thermal insulator inasmuch as it is non radiative even by its own
hydrogen-oxygen flame, but impurities in the early ocean seawater, though clouding it
black above the glowing magma, would have glowed brightly that hot ... thus the Earth
cooled by convection of superheated dirty water hot enough to glow [red] below its
heavily dampened atmosphere ... cooling of the Earth was not fast: It was cooking.
The Earth formed in the early pre-solar nebula (with all the planets) at rock-melting
temperatures, and cooled at a rate estimated in semi-classical physics as "gray-body"
radiation ... eventually it cooled enough to deposit metal, nodules, on the seafloor ...
and ultimately it cooled enough that dinosaurial creatures, possibly vent-worms, could
survive ... but that was only approximately a billion years ago: by fossil records:
The atmosphere had to cool before land creatures would take residence.
But before that eventuality, the sea temperature inverted-- for a period the top and the
floor were the same temperature, and there was no more convection [of significance].
Early sea dinosaurs must have therefor developed almost immediately -in geological
epochal relative terms- while the Earth was yet steamy weathering rock into sand,
and sand into dirt for vegetation ... though the earliest vegetation must have been
semi-hydroponic, growing in tidal pools. True vegetation came as quickly as it could,
and aided both conversion of rock to soil and atmosphere to oxygen.
(cf
GEN1 -In the beginning the Earth was without form, and void, and the Spirit of God moved
upon the face of the waters ... and on the fourth day [type] the stars became visible-.)
WATER ON THE MOON: More deposited by one midlatitude ice-comet,
than migrated at the poles.
NASA's Lunar Prospector neutron-spectrometry experiments found statistically significant
hydrogen, indicating mostly subsurface water-ice, 20° across the north pole 88°
and south pole 90°: 50%-more in the north pole.... However, It also found
upto-100%-more hydrogen implanted 25° centered 40° north on the near side,
tail twirled into the moon, and peppered centered 40° south on the far side ...
Meaning, a brief massive ice storm in recent history impacted water into the moon,-
recently enough to still show more water than the solar-eonic poles: and considering
evaporation rates in lunar-month sun the remnant water must be deeper than at the poles
and significantly more than 100%-more.... Since nearside had a narrow hit, and tail,
but farside had significant centering amid a full hemispheric hit, we can estimate that
the source was a dual-head ice-terroid gravitationally held by an extended ice-comma
within a broader hydrogen-rich cosmic molecular ice cloud: its long tail twirl nearside
suggests a gravitationally-compact rotating ice-comma being funneled-in from the cloud
till severed as the cloud impacted the farside, fallen back alone on the moon nearside.
