E.g. if we use a mirror to see an object behind us, the "normal" way for us to see it involves us turning our head 180 degrees.

    The result is that our brain auto adjusts for the 180 degree rotation, leaving us interpreting the final result as a reflection in X (left-to-right).
    All true, I think. I would just add that it's most confusing when you look at yourself in a mirror and see your reflection wave his/her 'left' hand when you wave your right. But the front-to-back reflected person - because we have nearly exact bilateral symmetry - looks a lot like a person just facing the other way. In fact it isn't, and it isn't his/her 'left' hand that moves when you wave your right.

    Look to the limits of your vision and you'll see the land in between is flat. Travel to where you could see and do it again. The land there will also be flat. Logically if the land is always flat between places then the earth is flat.

    That does actually make some sense - if you dont believe in the technology we have today!

    From Wikipedia:

    As yet unmeasured, but believed to be faster than light owing to its ability to move so quickly out of light's way.

    So, How does 'the dark' see and get out of the way of 'the light'?

    Would the mixture of 'dark' and 'light' result in a dim light/dark (or grey) when they cross each other?

    I've always thought dark must be faster because it's always there before light is.

    I've always wondered.. If a fly flies into your car, as your driving along, with all the windows open at 70mph, does that mean the fly is flying at 70mph too
