What I am about to say may sound a little complicated, but please have patience with me, and tell me what you think.
When we look at a globe, or a map, we are accustomed to seeing the USA, Britain and Europe in the Northern hemisphere, and Australia and New Zealand and other countries in the Southern hemisphere. We recognise the North and South poles.
But what if the world, in real life, is upside down and we do not know it?
Let me explain.
Imagine the world is a big ball hanging there in mid-air in a big expanse we call space. Imagine space as a huge large box. A massive box filled with earth, moons and other planets. All hanging in mid-air and spinning round.
The earth is spinning from left to right, giving us the impression that the sun rises from the right if we are facing North. But in effect the sun does not rise at all. It is in one stationary point and it is our spinning that makes us think it rises from the East.
East is just a word we invented. We could have called it something else. We could have called North, Norma, and South, Suzanne for all it matters.
By the way, and just as an aside, my uncle Ernest discovered the East Pole. It was somewhere on the equator but because the earth kept spinning he could not quite locate it.
Anyway, as I was saying … imagine the big box we call space is itself upside down and all its content is upside down. The earth would look like this.
And we would not know it. We would still be living on earth like normal. It would probably spin from right to left, but because we don’t know it, we would still see the sun rise from what we call East.
I know some people would say that when we send rockets into outer space the astronauts see the earth with North at the top. But for all we know, the spaceship could be travelling upside down and the people inside it don’t realise it. For in outer space there is no up or down. It is one big huge box and regardless of how people are travelling in the box there is no real up or real down.
It is just space. And we and the whole earth is in it. And all the planets. All, upside down.
Which explains why some people get headaches.
