Time Dimension To Become Space-like 587
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). 'We show that regular changes of signature on brane-worlds in AdS bulks may account for some types of the recently fashionable sudden singularities. Therefore, the fact that the Universe seems to approach a future sudden singularity at an accelerated rate of expansion might simply be an indication that our braneworld is about to change from Lorentzian to Euclidean signature. Both the brane and the bulk remain fully regular everywhere.'" Update: 10/09 16:06 GMT by Z : A few readers have written in to point out that the article is not peer-reviewed; your mileage may vary.

Oh, I'm living in a tesseract,
a four dimensional box.
It's bigger on the inside,
what why my four-space rocks!
When you get on the inside,
the outside becomes the in,
Dimensionally speaking,
it's all about the spin.

You're assuming that there is only one time dimension. But actually, from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey... stuff.

I suggest you read Relativity by Albert Einstein. He explains Special Relativity in simple mathematics that even somebody who has taken Algebra in US public school system can understand.
