So I heard that people see the world upside-down?

Question

I heard that, you know like when you look in a spoon everything is upside down, except we are the ones who are really upside down. Is this ture? So if an ET comes to earth we look like we are upside down.

Yea i know there is no up and down in space, that would bring me to another question, how does gravity waves work if there is nothing weighing down the object into the gravity fabric? but don't have to answer that lol

Answer 1

we do see the world upside down. the image passes through the lens and is flipped upside down, it is then processed by the retina. this in turn is relayed to the nervous system and the brain, which flips the image back and we see it as it naturally appears.

Answer 2

I think you have read something and got the wrong end of the stick.

The Earth is just a spinning ball. We tend to think of the North pole as being the top, and the south pole being the bottom. But that is just convention.

The universe is 3-dimensional space, and I believe from some of the weird and wonderful questions we get on here (and more so on Astronomy and Space) that many people cannot think in three dimensions.

Anyway, if you were coming to Earth from some distant spot in the universe, you are just as likely to come from the half of the sky that is seen from the southern hemisphere of Earth, as the half of sky seen from the northern hemisphere. North and south would be meaningless.

So you are just as likely to view the spinning Earth with the south pole on top as the with the north pole on top.

There is no up and down in space, other than which way your head or feet are pointing at one particular time. But your buddy could be up the other way. Which of you is the right way up? Neither of you.

Answer 3

actually what you see is upside down on the back of your eyes the brain has to turn it upright
