Mirrored Room

[Zacs-Master]

In a room where the walls floor and ceiling are mirrored, what would the reflection be of?

There,s nothing deep about what you see in a mirror, what you see is what anyone sees who stands in front of you, your right arm to an observer appears on their left.

No, it's on your left. If someone stands in front of you with a pen in their right hand, you can see it is in their right hand. If you do that in front of a mirror - it appears to be in your left hand. It's not the same.

Whereas if the observer is you, your right arm appears to be to your right, unless . . . you're standing before a double mirror, two mirrors aligned vertically at right angles to each other, then you appear to yourself orientated as others see you when standing directly in front of you, which by the way is the reason such mirrors are so arranged . . . if not in an attempt to shake your own right hand.

Here's some celebs who had each half of their face "mirrored" to show how asymmetrical our faces are. I know, nothing to do with the Q directly. I just remember seeing this ages ago.

The issue is not something the mirror does, the issue is what the observer thinks the mirror should do. It is that flawed expectation that causes the thought that a mirror transposes anything.

The image in the mirror is not another individual, it is an illusion caused by you looking at your own reflection. As such they do not exists to consider they have any left or right and if you try to put yourself in the illusion's place you will draw incorrect conclusions about the mirror transposing things.

If someone stands in front of you with a pen in their right hand, then for them it is on the right. But for you facing them it is on your left. It is only your ability to imagine yourself in their place that allows you to realise they will consider that hand to be their right. It is still on your left as you look at them. An illusion in the mirror can not consider which illusionary hand is which. It can not care.

As mentioned if you want the mirror to actually transpose the image to fit your belief in what is right then you need 2 mirrors fixed at 90° to each other so left is flipped to right before being returned to your eye, and vice versa.

But the crux of the confusion is that when you face someone the direction they call left is the one you call right. And the mirror reflects this truth. It's not like north, or up, which is the same for you and all around you.
