    I would like to remind the Forum that some here acquire great anxiety when asked to declare whether they believe that Earth rev around the Sun or the other way around.

    I am on record as saying E/S.



    I remember a funny quote from Galileo:

    "Scripture shows us how to go to Heaven, not how the heavens go!"

    I don't know if I would agree that the quote is 'funny' but it is worth noting tha Galileo and Copernicus both mistakenly deduced that the Sun was stationary and in the center of the Universe.



    That is true.  However, theirs was a step in the right direction.  Copernicus also believed that the planets orbited the Sun in perfect circles, which, of course, was wrong.  Kepler fixed that.  The ancients did not have everything wrong.  Ptolemy, in his Almagest, adopted an oval (elliptical) orbit for Mercury.  Of course, that orbit was about the Earth and not the Sun.

    Newton's theory of Gravity explains why we have satellite TV. Is this what you are getting at?  :confused1:


    It explains why we have satellites, hence, satellite television.


    I thought that is what you were getting at-- the satellites are in a fixed position at 22,500 miles up-- geo-synchronus.
    There Is No Such Thing As 'Sede Vacantism'...
    nor is there such thing as a 'Feeneyite' or 'Feeneyism'

    Exactly.  Relative to a rotating Earth.  Hence, they spend roughly 12 hours in darkness (so we can watch TV at night) and 12 hours in daytime (so we can watch TV during the day), the latter time is when they recharge their batteries using sunlight from the Sun!
