| subject: | Is Pluto a planet? |
-> hunh? ok, i'll accept that with an eye toward "lunar
eclipse" as well as "bo
-> rotation" (which is what keeps the same face of the moon facing
the sun all
-> time) ;)
The same face of the moon (roughly) faces the EARTH all the time, not
the sun.
-> in fact, i recall some studies that state that the moon is removing rotation
-> speed from the earth (via tidal forces, i believe) and that at some time in
-> distant future, the earth will stop rotating... this same recollection also
-> states that this is one possible explanation for biblical longevity
-> statements... ie: their years were shorter giving them more of them in the s
-> rotational and circumferential period that we have now... ie: 365 days to
-> circle the sun...
-> does that make sense? i sure hope so...
-> )\/(ark
Yes, Earth's rotation is being slowed by tidal friction, and someday in
the far distant future, one hemisphere of the Earth will face the MOON
all the time, so both bodies will have tidally-locked rotations. (This
situation already exists with Pluto and Charon.) Beyond this point,
theory says that energy will continue to be removed from the system by
sun-induced tides, which will cause the moon to spiral inward, the
rotations of both bodies to speed up, and eventually the moon to be
destroyed. By that point, Earth will be rotating fast again. After the
destruction of the moon, Earth's rotation will slow down until one
hemisphere faces the sun all the time.
However, this theoretical scenario is very unlikely to be carried to
completion. The sun will expand to become a red giant, and swallow
Earth and Moon long before the moon is destroyed.
Your religious speculation is pure drivel.
