Submission + - Creation of entanglement simultaneously gives rise to a wormhole (mit.edu)

Submitted by Ashenkase
Ashenkase writes: Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics — so strange, in fact, that Albert Einstein famously referred to it as “spooky action at a distance.”

Essentially, entanglement involves two particles, each occupying multiple states at once — a condition referred to as superposition. For example, both particles may simultaneously spin clockwise and counterclockwise. But neither has a definite state until one is measured, causing the other particle to instantly assume a corresponding state. The resulting correlations between the particles are preserved, even if they reside on opposite ends of the universe.

But what enables particles to communicate instantaneously — and seemingly faster than the speed of light — over such vast distances? Earlier this year, physicists proposed an answer in the form of “wormholes,” or gravitational tunnels. The group showed that by creating two entangled black holes, then pulling them apart, they formed a wormhole — essentially a “shortcut” through the universe — connecting the distant black holes.

I am glad they picked a location that experiences Winter in all its harshness. I always wondered how an autonomous car would deal with all the challenges that Winter driving poses. Black ice and snow covered surfaces are the worst of the conditions, but throw in snow patches, high winds, variable visual conditions, etc and the software will probably start showing its weaknesses.
