    Default Learning Basic Astronomy



    You're following the European development of mankind. Do yourself a favor and
    learn about other cultures and their achievements.

    I couldn't agree more. Most of the cultures on this planet, including
    most of the indigenous ones, knew the earth is round, and that the earth
    and the planets revolve around the sun, literally millennia before
    Europe managed to crawl out of the Christian dark ages, largely with the
    help of ARAB astronomers, all of whom were also astrologers.

    What's obvious, if you look at the traditions of this planet at large,
    is that Europeans have been slow to catch on to the common planetary
    cultural knowlege, and that, in general, they continue to be incredibly
    arrogant in their assumption that everyone else is, and always has been,
    as stupid as they are about things like what is actually visually
    discernable in the sky to the unaided human eye, if you will just slow
    down long enough to actually look at it.

    Actually I think you'll find that the misconception that anyone thought
    the Earth was flat is fairly recent. There may be passages in the Bible
    that imply it, but that's all.
    There's a Bronze Age monument in Britain that runs along a line of
    constant bearing, implying that someone knew the size of the Earth and
    wanted to demonstrate it.
    But is there any evidence for widespread belief in a heliocentric system
    before the time of Copernicus? The Greeks toyed with the idea in about
    300BC but they didn't like it - it's philosophically unsatisfactory and
    _very_ hard to prove.

    They were, also astrologers, because they did not differentiate a
    prophesy/science thing a millenia ago. But we do.

    To get back to your other point - what is your evidnce to back up your
    stated fact? It's one thing to make a factual sounding statement and
    another thing to give detail on what basis you made the statement.
    Like the European post did ( doesn't have to be a thesis).

    So, what's your evidence?

    Aristarchus used logic to show heliocentrism as opposed to the
    "widespread" belief of geocentrism. The weakness of such an
    argument is that if most people don't accept the logic, then the
    argument dies. And most people didn't accept Aristarchus' logic.

    Copernicus noted that the math needed to marry planetary motion
    with geocentrism was way too complex. But when he applied the
    notions of Aristarchus the math became so much simpler, and he
    could easily account for the occasional retrograde motion of the
    planetary orbits. With his finally printing his ideas in a book, and
    his death before the poop hit the fan, came the birth of the so
    called "scientific revolution."

    Yet it would be about fifty years before scientists could even begin
    to turn their backs on the Ptolemaic geocentrism. And nearly
    seventy years before Galileo would provide hard evidence using
    the phases of Venus and the Galileans of Jupiter. So it may rely
    upon your ideas about "widespread."

    Heliocentrism came into fairly widespread popularity among
    scientists soon after Galileo's findings. And yet it would be many
    years before the western general populace, a very religious group,
    would accept the seemingly heretical conclusions of science.

    And then... along came Harlow Shapley! (the galaxy is the
    Universe and our Sun's not at its center -- "galaxocentric?")

    And then... here comes Edwin Hubble! (our galaxy isn't the
    the whole Universe, but just one of many other galaxies. This idea
    was actually first set forth by Immanuel Kant in 1755 with his
    "island universes," but nobody believed him except maybe Ben
    Franklin.)

    So it's possible that among the public, heliocentrism was never
    really a very widely held belief, at least not for very long. We
    quickly jumped in a relatively short span of time from the Greek
    geocentrism that had lasted for nearly two millennia to present
    day beliefs...

    Aristotle ~ 300 BCE
    Claudius Ptolemy ~ 135 AD
    Nikolas Copernicus -- 1543
    Galileo Galilei -- 1610
    Harlow Shapley -- 1920
    Edwin Hubble -- mid 1920s

    happy days and...
    starry starry nights!

    --
    Our heads up in the sky,
    We're so clueless of our worth...
    Whose sky no longer shines
    As we lose our Mother-Earth?

    As people we must learn
    About the care of planet parts,
    To leave the world a better turn--
    Empower brand new hearts!
