The scientist who find the point where super position stops will get the Nobel price for sure, I could give you a hint, it is less than my cat, I'm sure it never been in two places at once (Schrödinger is right about his cat too)

Or maybe the odds of your cat being in two places at once is miniscule and is less and less likely the more lasagna he or she eats.

Damn, it wasn't so easy to find the article, because TFA doesn't explicitly provide author names, even. But the link in the image title led to Fein et al. (2019).[0]

So what I'm curious about is how far apart those "Two Places at Once" are. And if I'm understanding Fig. 2 correctly, it's large. That is ...

> Fig. 2 | interference data. a, Counts as a function of the transverse position of the third grating with a sine-fit (solid black line) yielding a visibility of 25 ± 3%. The optical grating power was 1.2 W for this single scan. Counts are dark-rate-corrected and normalized to the control measurements.

... with peaks at ~200 nm, ~430 nm, ~680 nm and ~900 nm.

But a 25 kDa molecule is only ~4 nm in diameter.[1]

That's amazing!

Or your cat is always in all places but your experience only one. At least that one of you.

Earlier quoted context omitted.

In any case, the cat is the boss in all instances. My cat is very disappointed in me right now that I can't stop the onset of winter and demonstrates it very effectively!

There is probably some space-time position where he is completely content but I think that's rarer than seeing him in two places at once.

Superposition is not stopping as far as we know it.

Cat typically weighs 3,6 – 4,5 kg. De Broglie Wavelength of 4 kg cat moving 1×10^-10 m/s is 1.7×10^14 m.

You cat is in many places at once, those places are just very close to each other.

I'm off shooting cats through two slits I made in my living room wall now, to prove or disprove you. For Science!

> it is less than my cat...

Wouldn't it be ironic if decades of misdirected science could have been avoided if Schrodinger put his hamster in the box.
