Weird stuff

Einstein had a theory about this.

Okay, then what's the fucking theory????

Dunno, ask Albert.

So you're all, "Okay, so Einstein had a theory about people being seen in different places at the same time" but then you high-tail it when I ask you for more info?

Seriously, that's wank.

Briefly, the paper imagines two particles prepared in a mutual quantum state (a superposition), so that a measurement of the properties of one particle — position or momentum — would determine that of the other. Erwin Schrödinger dubbed such a state “entanglement.” According to the Copenhagen interpretation, a recording of the position of the first would trigger the combined quantum state’s collapse into position eigenstates, corresponding to certain position eigenvalues. Conversely, a reading of the momentum of the first, would precipitate a collapse into momentum eigenstates. However both position and momentum, as conjugate variables, could not be measured at the same time.

Now suppose the particles interact with each other and then are separated. How could one know instantly which type of eigenstate — position or momentum — it would need to be in, based on a measurement of the other one? It would have to be able to “read the mind” of the other particle or of the experimenter!
We can see why Einstein would be disturbed by such a scenario, even if it produced accurate results. Einstein was convinced that quantum mechanics offered an incomplete explanation of physical phenomena. From his perspective the need for “mind-reading” was a flaw of the theory.
Later, John Bell reimagined the EPR thought experiment, replacing position and momentum with spin states (electrons can have spin up or spin down), and developed a test for whether or not quantum interactions could be non-local (such that if one is measured spin up, the other must instantly become spin down, and the converse). Indeed actual experiments have shown that quantum state collapse does yield the instant effect that the eigenstate of one determines the other. Entanglement is now being exploited in the development of quantum computing.

It was on the topic of creepy things kids have said to their parents.

So a little boy calls out to his dad one night and says he's scared, asks his dad to check under the bed for monsters.

The dad obliges and looks under the bed, where he sees ... his son!

The boy is trembling, and he says to his dad:

"I think there's something in my bed."

sort of ... his theory was only an observation of atoms, 
but in 'pop culture' is extrapolated to apply it to humans or larger beings/object
