Submission + - Time dimension about to become space-like (

KentuckyFC writes: "The Universe is about to flip from having three dimensions of space and one of time to having four dimensions of space. That's the conclusion of a group of Spanish astrophysicists who have calculated that observers inside such a Universe would see it expanding and accelerating away from them just before the flip (abstract, full paper pdf on the physics arXiv). The curious thing is that this accelerated expansion is exactly what astronomers have been seeing in the last few years and been unable to explain."
