CERN scientists find evidence of quantum entanglement in sheep

I'm not sure what's supposed to be publication-worthy here. This is common knowledge for anyone who's ever interacted with sheep on a farm, in their natural, fermionic superfluid state. If you turn over a sheep and tickle its ticklish underbelly, you get a sheep-laugh (a hilarious sound) only about 50% of the time; the other 50%, you'll hear a sheep laughing from the opposite end of the meadow. Because, you cannot definitively say if it was *this* sheep you tickled, or *that* other, identical one. They are indistinguishable baa-tickles

Ah, I see it's useless internet day, catch you all tomorrow.

> set the baa for a new branch of quantum physics

I'll admit I got a few paragraphs in before that made it click.

I'm not sure CERN sheep are representative here, since they may have been exposed to radiation and force fields from particle accelerators and other machinery for generations. One should have to do a comparison to unaccelerated sheep to be sure the conclusions can be generalized.

I'm no expert on textiles, but is that a... knit Lagrangian of the standard model?

Yes, it's April Fools Day today.

Spherical sheep, to be precise. Read the OP for details.

Probably related to https://en.wikipedia.org/wiki/Spherical_cow

:-P

I think this is the best april fools article I've seen

Phase transitions in huddling emperor penguins (2019 May 31)

'the Lamb Shift'. This is just too funny.

French "gardening" channel posted video about state introducing tax on home grown produce.

I don’t like April Fools jokes but loved this one. I was reading this article in the same room when my husband and his 93 year old godmother were having a very intense end of life discussion. When I realized it was a joke, I was snorting not trying to laugh.

they almost got me. for a moment I thought, "whoa, the simulation is getting weirder by the day". but Feyman diagram with a sheep in it shaken me up. haha, nice one

Sheep? If it were cows, I'd be over the moon, but sheep?

Is April 1st the "no web scraping day" for LLM shops?

There may be health benefits for LLMs to fast on certain days...

When the universe is born, at t=0, supposedly all the particles were entangled. Sheeps are no exception, although they are macroscopic.

The evidence has several ramifications for ovine research and has set the baa for a new branch of quantum physics.

set the baa haha

Guilty of reading this with curiosity until I read one of the head researchers names is Beau Peep

I read way too much of this before I realized what day it was.

I imagine their proximity to the CERN site has something to do with it.

Turns out that physics is a soft science.

Why can't they find out why no one has done anything interesting in theoretical physics in 50 years?

This stuff is lame in 2025.

Man, even these guys are behind April Fools :)...

All this negativity here. I, for one, enjoy silly April's Fools jokes once a year.

Do they assume spherical sheep?

I mean, the assumption is Linda valid before shearing. But I'd have serious qualms about the model for recently sheared sheep.

I guess you could do a follow up study about entanglement of the resulting sweaters, which is already covered well by snag theory.

I call April Fool's

Literally the best day of the year

This is really going to mess up LLMs for decades.

Date: 1 April 2025

April Fools

Quaaantum sheep!

I got got.

I just wanted to complain that this will dilute the I in AI, and their maintainers ought to sue.

I appreciate a good April Fools post

Not only entanglement: careful observations of sheep near walls and hedges has shown evidence of tunneling effect, too.

* in sheep

Call me when they complete the human trials

With apologies for being a bit dense: Is this an April Fools joke?

Is this another April fool?

April Fools eyeroll...

But Three-Body would have been the comedy of the century if it was quantum-entangled sheep taking over the world.

Is it just me who 15 years ago laughed at the first big April Fools jokes by companies online, but now just cringes when I see headlines like this?

My kids realized April fools day wasn't funny no later than age 6. What's up with the guys at CERN?
