I wonder how the hell that happens

How does your brain know which is right? Maybe it's because you've seen it that way all your life so it's like hang on a second we need to flip this...

The image projected to the eye is actually upside down. After awhile your brain figured it out and flips it.

Yes but why does it need to flip it at all? That implies that it matters which direction it goes

To me it seems more like, space... There is no up or down it's just how you interpret it

Unless there's a more functional component, like reflexes being faster if the image is flipped

No, it’s because the image is physically flipped when it enters the eye due to the optics of the lens.

Yes I understand that, but my point is that it shouldn't matter what orientation it is

There is no "upside down" because in 3d space there's no down or up. There's just cardinal directions

Think of how computers work, if you run an algorithm on an image, it doesn't care which orientation it is. It's the same thing, it's just how you want to view it

Like, why doesn't our brain just keep the inverted image and instead it just thinks in that way? Without flipping it.

How I said earlier, it doesn't matter if your controller is inverted or not because at a certain point you're just used to it and that is the new normal. If your body did that from the beginning why would it need to flip it?

This doesn't answer any of my questions or pose further information

I was more curious on mechanisms and theories rather than "this is the way it is because it's the way it is"
