Title: The World’s First Photo of Quantum Entanglement Could Disprove Einstein’s Theory

Einstein dubbed the idea of quantum entanglement as "spooky action at a distance." Now for the first time ever, scientists have taken a picture of it.

Today we understand quantum entanglement as when a pair of particles that cross paths and interact with each other can become connected and stay that way, even when the particles are spaced very far apart.

Once particles are intertwined in this way, changes to one particle can immediately shape the other particle, an odd scientific phenomenon that has been proven through experiments with atoms and molecules, and more recently through entangled objects of even larger scales.

Quantum entanglement is a key part of quantum mechanics, which forms the basis for fields such as quantum computing and cryptography, so there is considerable interest in advancing our understanding of it.

For scientists at the University of Glasgow, this led them to study a form of quantum entanglement known as Bell entanglement, described by late physicist John Stewart Bell.

Albert Einstein conceived of special and general relativity, but when it came to the idea that two particles can be entangled, and an impact on one particle could be instantaneously felt by the other particle, even over vast distances, for Einstein that was simply unbelievable.

Einstein even went to his grave a skeptic, but since then, quantum entanglement has been demonstrated time and time again, and now for the first time ever,  researchers from the University of Glasgow have taken a picture of it.

More on old result?  The title seems to be click bait ... see Alain Aspect circa 1972+ ... with predecessors and many followers (concerning reality of entanglement)

The trick is exactly what Bell's Theorem means or doesn't mean.

https://en.wikipedia.org/wiki/Bell%27s_theorem

But then again, there is no unity on the interpretation of QM itself.

Quoting from Wikipedia on Hard Science? Really?

Wikipedia is a lot better than the average source.  Given the self-regulating fact-checking by people who are experts, I tend to give it some authority.

Even Joe wouldn't understand this shit.  Do you?  Reeeeeally?

Yes, I was studying GR in HS, when some people here weren't even ova yet.

GR?

GR = General Relativity
QT = Quantum Theory
QFT = Quantum Field Theory

No, but sometimes I fall into catblogese.  My apologies, I was on all night there.
