Your facts are wrong. You are getting an obit time mixed up with a
rotation time.
No, I'm afraid that your "facts" are what is wrong. You don't
understand that rotation is not necessarily relative. The moon does
rotate with respect to an interial frame. It just happens to rotate at
about the same rate as it revolves around the Earth which is why we only
see mostly one side when we stand here and look at it. If we somehow
remmoved the Earth, the moon would continue rotating every 27 days or
so. If you were standing on the sun and looked at the moon with a
telescope, you would be able to see each side as it rotates, just as
when we look at Io from Earth, we can see it rotate as well. With
respect to the sun, the Earth's moon rotates. If you were standing on
the moon and looking at the stars, you would see them rise and set.
With respect to the stars, the moon rotates. The moon's orbit is also
not circular, so at times, its velocity is different than its rotation
speed. Thus, we can see the moon appear to rock back and forth thus
demonstrating that it *does* rotate.
Venus does rotate, but not in 20 days! This is again an incorrect
statement.
Insults are not needed.
No insults were provided! You don't appear to understand things when
many people here have been patient enough to try to explain things to
you. You can't seem to grasp how rotation works (as well as a bunch of
other things which you made mistakes on). The fact is that you *need*
to take some courses in the sciences so you can understand basic
astronomical concepts. You also haven't read the sci.astro.amateur
charter which states that discussions like this are somewhat off-topic
for that newsgroup (sci.astro.amateur is for the hobby of amateur
astronomy and not speculative scientific discussions). To continue with
your postings here is to invite derision. So be it....
