According to all the history books, history teachers, and history TV channels, back before Christopher Columbus everyone thought the world to be flat. That was proved to be wrong. The Earth is almost a sphere; almost, because it bulges at the equator. That must be caused from the centrifugal affect from its spin.
OK, now that also got me wondering. If the Earth has a larger diameter at the equator, would we weigh more standing there because of the extra gravity or would we weigh less since the centrifugal force is trying to throw us off. On the contrast, what if we sere standing at the north or sough pole? There would be negligible centrifugal force there, just gravity, so would we weigh more at the poles or less? Ok, now I am getting dizzy so better get back to my main subject.
Now, we have established that the Earth is round or near so, so what about the Universe? What shape would you think it is? If you believe in the “Big Bang” theory, then I would suppose you would have to believe that the universe is a sphere. I always did, but now the scientists are telling us it is flat. Where is Columbus when you need him? . . . Oh yeah, Columbus is in Ohio. This is the opposite of the Columbus story.
Yep, they say the universe is flat, a brane, and not only that, they believe that there are many of them stacked side by side, like pages in a book. From here the story gets complicated and way beyond my comprehension, so this is a good place for me to quit.
You all have a good day now, you hear.
