Time Dimension 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). '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 Update: 10/09 16:06 GMT by Z : A few readers have written in to point out that the article is not peer-reviewed; your mileage may vary.
So that's whats going to happen when the Mayan calender rolls over in 2012.
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.

I first read this theory in Oolong Caloophid's seminal work: "Where God Went Wrong."
More of this is elaborated in his development of these themes: "Some More of God's Greatest Mistakes," and "Who Is This God Person Anyway?".

No, but your slashdot ID# should cease to matter.
and there was much rejoicing.
(holy crap we have close #'s too)

I'm guessing some time in the future.
I really hope I'm not in the DMV when time ends.
Silly... obviously the question is NOT "When will this happen?" Without time there is no "when", and no "happen", and no "will". Only "this".
Should this research be correct, the only question left will be: "This?" Now and always and forever, this?
I have seen the future, and it is inconvenient.
The peers are going to review this a few centimeters from now; give them time.
The real question is not "when is this expected to happen?", but where? I think it already happened on the NJ turnpike a long time ago

All this talk about time becoming a spatial dimension and realities collapsing is making my brane hurt.
Yeah, I said it.

slashdotters comment on science topics. Top comments are always "Funny" because no one really understands what it's all about and so everybody just makes stupid jokes instead.
Namaste
It's not the future anymore. It's just "that way". *Points*
In the future, time will become very confusing...
Dark Helmet: What the hell am I looking at? When does this happen in the movie?
Sandurz: Now, you're looking at now, sir. Everything that happens now is happening now.
Dark Helmet: What happend to then?
Sandurz: We passed then.
Dark Helmet: When?
Sandurz: Just now. Were at now, now.
Dark Helmet: Go back to then!
Sandurz: When?
Dark Helmet: Now.
Sandurz: Now?
Dark Helmet: Now!
Sandurz: I can't.
Dark Helmet: Why?
Sandurz: We missed it.
Dark Helmet: When?
Sandurz: Just now.
Dark Helmet: When will then be now?
Sandurz: Soon.
Dark Helmet: How soon?

So you're saying the universe will become a Fark thread?
..maybe if I wait a few feet it'll feel better
Change requires time. It's a logical paradox.
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.

Breaking "time's arrow" will really fuck with our verb tenses.
But I worried about that tomorrow...

A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort.

You still haven't produced the code for COSA, its been more than a month. Do you have it?
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.
