Is ... is that ...
@s_palm it could be. I am only half sure.

A. Photograph. Of. Quantum Entaglement. OMFG.
@s_palm
I’m thinking: glimpse of parallel universe.
@s_palm Schrodinger is rolling in his grave... or not I haven't looked

@s_palm

Yes, it is.
That's the only known physical evidence of Schrödinger's cat.
Very lucky shot.

@TheAuthorVivian @s_palm

If only Schrödinger could see this!

A proof of concept at it's best.

@s_palm Yes. It's Shröedinger's cat.
@s_palm
Never mind the physics, I have never seen a more poignant depiction of unfulfilled desire.

@s_palm the alt text really should be a description of the image, it's not a place to put the punch-line of a joke :/ Here's a description that I came up with that could work here:

A cat is visible sitting inside the reflection of an empty cardboard box in a glass patio door.

@kepstin @s_palm

How about this for alt text?:

Photograph showing a box and it's reflection through a semi transparent mirror. A cat behind the mirror looks like it is in the reflection of the box, while the box itself appears empty.

@Blort @s_palm that's good! I like it better than my suggestion.
@s_palm Hey Mr. Schrodinger, you got a package!
@s_palm

(fantasy)

schrödinger's box. the cat both chooses the item that you gave them and the box that it was in, until you start to look at them. this causes the cat to quickly clean up the item and place it right where you had left it, and get firmly into the box.
@s_palm funny, I have this picture saved on my phone but it is reversed; I wonder which way is the original
@s_palm
It might or might not be.
Er...it might and might not be.
@s_palm One thing you can say about that cat, it's definitely sitting in a super position.
@s_palm we finally have a picture of Schroedingers cat!
@s_palm Package for Schrodinger.
@s_palm Vampire Cat? Just the other way round?
@s_palm it might be, but don’t look too closely
