A Link Between Wormholes and Quantum Entanglement

This advance is so meta. Theoretical physicists have forged a connection between the concept of entanglement—itself a mysterious quantum mechanical connection between two widely separated particles—and that of a wormhole—a hypothetical connection between black holes that serves as a shortcut through space. The insight could help physicists reconcile quantum mechanics and Einstein’s general theory of relativity, perhaps the grandest goal in theoretical physics. But some experts argue that the connection is merely a mathematical analogy.

That’s true. No argument there.

This is getting a little esoteric.

Start by imagining an entangled quark-antiquark pair residing in ordinary 3D space. The two quarks rush away from each other, approaching the speed of light so that it becomes impossible to pass signals from one to the other. The researchers assume that the 3D space where the quarks reside is a hypothetical boundary of a 4D world (i.e. the holographic principle). In this 3D space, the entangled pair is connected by a kind of conceptual string. But in the 4D space, the string becomes a wormhole.

I really don’t follow this. The two quarks can never reach the speed of light so it is always possible to pass signals from one to the other. Or am I missing something?
