Since you won't recognize that (physical) life and intelligent beings are a 
good physical reason, will you be intelligent enough to accept it as very 
important data ?
Marc, I don't understand why you keep pursuing this. My point is that whether 
Man is there to observe or not, the universe will still be doing what it has 
always done. Example -- New Zealand was discovered and occupied as a genuinely 
uninhabited land by Polynesian people sufficiently recently that the verbal 
tradition has preserved a record of the events. When they arrived, they found a 
land significantly different in flora and fauna from their island's of origin 
and it had clearly been in existence in that state prior to their arrival 
unless you are going to claim that each atom discovered came into existence as 
a result of being discovered. As Man does, they promptly set about changing 
things such as wiping out the moa and introducing pigs which were instrumental 
in wiping out other species. It doesn't matter that Man wasn't there earlier, 
the land still did what it had always done.
Now concerning the difference between sidereal time and mean solar time. I have 
to use the heliocentric position to explain this because even if the geocentric 
position has an explanation, I have no idea what that might be but you can bet 
that it would be complex. On Earth we have a year -- one revolution around the 
Sun -- of approximately 365.25 mean solar days. In this time the Earth has 
rotated 365.25 + 1 times. The difference of one rotation spread over 365.25 
days is 236 seconds which is 3.94 minutes which is the difference between a 
sidereal day and a mean solar day. Now bear in mind that a sidereal day is the 
time for a given star to cross a given longitude twice while a mean solar day 
is the time for the Sun to do the same.
Now suppose that the Earth does not take 365.25 mean solar days to make one 
revolution but instead takes 364.25 but still in the same orbit (thus the 
rotation rate would be different). Now it will have made 364.25 + 1 rotations 
per revolution thus the mean solar day would then be -- 365.25 * 86400 / 364.25 
= 86,637 seconds -- 237 seconds longer than previously. Compared with the 
sidereal day of 86,164 seconds, we see that the difference between the solar 
and sidereal days will now be 473 seconds ie 7 min 53 sec. So you see, the 
difference is determined by two factors -- The length of the year and the 
period of rotation, which is the sidereal period.
Now Mars has a year of 687 Earth mean solar days and a sidereal day of 24h 37m 
22s ie 88,642s. Therefore the Mars year consists of -- 687 * 86400 / 88,642 = 
669.62 sidereal days. There will be one less Mars mean solar day -- known as a 
'sol' -- so the sol will be 687 * 86400 / (669.62 - 1) = 88,775s. If we 
subtract the sidereal day from this we get -- 88,775 - 88,642 = 133s = 2m 13s. 
I think for a rough calculation that should be close enough.
I don't want to be "picky", but since you are stressing on precisions, you 
should write (about Sun rises) that it is an average frequency.
Yes it was average but if I were to define every statement to a level 
sufficient to satisfy a High Court challenge you'd find it very dull reading -- 
even duller than you find it now! |[:-)
