Wormholes Untangle a Black Hole Paradox
An anonymous reader writes: Like initials carved in a tree, ER = EPR, as the new idea is known, is a shorthand that joins two ideas proposed by Einstein in 1935. One involved the paradox implied by what he called "spooky action at a distance" between quantum particles (the EPR paradox, named for its authors, Einstein, Boris Podolsky and Nathan Rosen). The other showed how two black holes could be connected through far reaches of space through "wormholes" (ER, for Einstein-Rosen bridges). At the time that Einstein put forth these ideas — and for most of the eight decades since — they were thought to be entirely unrelated.
But if ER = EPR is correct, the ideas aren't disconnected — they're two manifestations of the same thing. And this underlying connectedness would form the foundation of all space-time. Quantum entanglement — the action at a distance that so troubled Einstein — could be creating the "spatial connectivity" that "sews space together," according to Leonard Susskind, a physicist at Stanford University and one of the idea's main architects. Without these connections, all of space would "atomize," according to Juan Maldacena, a physicist at the Institute for Advanced Study in Princeton, N.J., who developed the idea together with Susskind. "In other words, the solid and reliable structure of space-time is due to the ghostly features of entanglement," he said. What's more, ER = EPR has the potential to address how gravity fits together with quantum mechanics.

Really big things nobody really understands are surprisingly similar to really little things nobody understand -- with both groups exhibiting some really confusing long-distance connections we don't really understand.
Beyond that .. I confess I don't have a clue, and you're on your own for a car analogy.

1) The ER effect, is when you go with your dad to buy a cool convertible, but somehow comeback from the dealership with an beat up AMC Gremlin
2) The EPR effect is when two cars that were once touching, continue to effect each other at a distance, the primary example of which is how when you are behind a slow car, when you move over to the fast lane, suddenly the slow car speeds up, leaving you in the distance.
They have discovered that both of these effects are actually the same thing - it is fact the Gremlin that causes the previous fast lane to slow down.

...in fiction, basic discoveries of this magnitude promptly lead to anti-gravity, flying cars, space travel, and replicators.
In real life, some PhDs are pleased with themselves and now understand why we exist and aren't a cloud of random particles - but I *still* don't get a damn jet pack.
Oh, well: the announced today that they have asthma figured out at last and can probably cure it soon. I don't have asthma, but I'm glad we also got a practical discovery.
There, solved it for you. Where's my grant money?
Imagine a chicken's butt. picture it. Okay hang onto that thought because we'll come back to that later.
There's a house made of rubber with a lot of rooms. While all the guests including the butler are gathered in the living room, the guests hear the sound of the master of the house being murdered in his bedroom which is at the end of a distant series of hallways. They also notice that at that moment the butler is missing, but a moment later he's back. It's too far from the dining room to the bedroom for the Butler to have walked there and walks back, so he's not a suspect. But we have two mysteries
1) how did the butler vanish and re-appear. Very suscipicious. could he teleport?
2) how did they hear the scream of the master in his distant bedroom.
The second fact seems to clear the butler since no one wants to believe in teleportation.
Then they discover the house is U-shaped and there's a secret passage directly connecting the bedroom to the living room. The spooky actions and effects at a distance are explained by a wormhole. Also it's the secret passage way that holds the rubber house in a U-shape.
Now remember that chicken butt? I thought so. See if you can get it out of your mind.
Some drink at the fountain of knowledge. Others just gargle.
The pudding is a metaphor, of man's eternal longing for an answer to the questions ... "what the fuck is that? You're not really going to eat it are you?"
It just sits there, looking all gooey and non-Newtonian. It's just so wrong.
*shudder*

It's entangled with its dupe. Finish observing this one and the other should show up via Google.
