Up until last year, mathematician Peter Bierhorst had hoped the physicists he works with would fail. It was nothing personal. He just found their worldview a little disturbing.
Like most physicists, his co-workers believe that our universe’s particles can influence each other using a sort of telepathy. Called “entanglement,” this connection allows two particles separated by vast distances to behave as a single entity. Both instantly react to something that happens to one of them.
If you find this very weird and counterintuitive, you’re not alone. “I find this very weird and counterintuitive,” says Bierhorst, a postdoc at the National Institute of Standards and Technology. Albert Einstein felt the same way. Unfortunately for them, experiments have finally showed beyond a reasonable doubt that entanglement exists.
To understand entanglement, you must first accept that reality is unsure of itself at small scales. In 1927, Werner Heisenberg argued that it’s impossible to know both a particle’s position and momentum exactly. Measuring one simply makes the other fuzzier. Particles are fundamentally indecisive — neither precisely here nor there, and both at once. Making measurements effectively forces particles to choose how to behave. Einstein disliked this idea of a random universe; the atheist famously proclaimed his disbelief that God played at dice. (Quantum pioneer Niels Bohr supposedly replied, “Einstein, stop telling God what to do.”)
So peeved was Einstein that he and his friends came up with a thought experiment to show how it was possible to learn both the positions and momentums of pairs of particles. Preserving their uncertainty would require one particle in the pair to instantly know and react when the other is measured — even at the other end of the universe.

"Every story about entanglement is obligated to include Einstein’s reaction to this apparent faster-than-light communication: “spooky action at a distance.” Unwilling to accept it, he declared quantum mechanics incomplete."
Having once been married and now divorced, I know more than I ever wanted to know about ‘entanglement’! Unfortunately, it is ‘spooky action’ but it is up close and personal.
Does this have something to do with the sci fy theory of Parrel Universe?
Paging Anna DeWitt....
Article is disappointing. Just talks about quantumn mechanics being weird instead of giving the reader enough background to see how it is very weird.
Glad to see they're improving this timekeeping record. Sure is a shame to lose that second over 15 billion years.
Oops. There goes another one...
The "Parallel Universe" idea in science fiction is indeed related to quantum mechanics. Its usually called the "Multi-World Interpretation" (MWI) for the collapse of probability waves. However it is not a popular hypothesis (the most popular I *think* is the Copenhagen interpretation).
But before one can understand why physicists would even consider hypothesizing "parallel universes", one should start with the double-slit experiment. Here is a popular 5 minute cartoon video introduction to it
Analogizing a hydrogen atom's nucleus to a basketball sitting in Kansas City and its electron to a BB circling at the radius of the distance to New York City, one can't affect the BB's orbit without the nucleus already "knowing" about it as it happens. The affected electron doesn't begin drafting a message that will be dependent on the speed of light to reach the nucleus about an effect that has just happened, the nature of the (harmonic resonating) "music of the spheres" system already "knows" all about it. The glory is that we can piggyback along with that "music" and leave any worries about light speed limits at Einstein's grave site.
Spooky action at a distance
I wonder whether the error is assuming the particles are ever really independent, and that one actually needs a wave function to handle both particles "all along".

Not really, because space and time are illusions created by our conscious perception. Immanuel Kant figured it out by sheer reasoning, Minkowski did the math.
Entangled particles are not exhibiting spooky action at a distance because in a higher dimension they (and everything else) are in the same place, and in the everlasting now.
The world of time and space we experience is a computationally-derived presentation, thank God.
I should have added a sarcasm tag. I thought it was obvious
Robert Lanza speaks of this in his theory that the universe was designed to give life. Everything is biocentric. There are hundreds of physical phenomenon that are so infinitesimally small, like the amount of current allowing electrons to spin around the nucleus, if there was the slightest deviation the uinverse would not exist, let alone life. It all hinges are the width of a thread, but then it all fits to give life. It is hard to imagine this randomly occurring, the probabilities for this much precision at so many different levels is too much to conceive.
Get his books. BIOCENTRISM
Makes my brain hurt...
