Top 10 Reasons We Know the Earth Is Round [Video]

While none of us are arguing over whether the Earth is anything but round, this entertaining video from Minute Physics explains ten distinct reasons why we know we live on a sphere.

  1. HEY ZEUS! (Get it?)

    You mean the Earth isn’t round like a DINNER PLATE?! :-D

    What about Santa Clause or the Easter Bunny? I bet you’re also going to tell us that there’s no all-seeing all-knowing deity who made it all too. Right? ;-)

    Hi :-)

    The earth is not flat but round, is that you say? Fine.

    A round figure is a 2 dimension entity.
    Therefore “earth not flat but round” means “earth is not flat but flat”… ;-)

    To be accurate the earth is an unregular spheric entity.

    Have a nice day.

    The Earth *is* FLAT !

    In 2 dimensions, the Earth is generally flat. How could you sail around the planet if it was not ?

    BUT, the Earth is also curved – in a third physical dimension !

    It takes a bit of imagination to see that the Earth is BOTH flat .and. curved at the same time.

    Fun Fact: a doughnut (toroid) IS mathematically flat; an arbitrary triangle always has exactly 180 degrees !

    It, too, is both curved and flat at the same time !
