Time Dimension To Become Space-like

Zonk posted more than 6 years ago | from the you're-not-thinking-fourth-dimensionally dept.

Space 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 Update: 10/09 16:06 GMT by Z : A few readers have written in to point out that the article is not peer-reviewed; your mileage may vary.

Yes!

In "Slaughterhouse Five", Vonnegut wrote about creatures who perceived time as a geometric dimension. They could perceive their entire lives as a wide landscape, stretching from past to present to future... and they could move freely within it, to relive the better moments and fast-forward over the unpleasant ones.

One of the implications that these creatures could see, but which we could not, is that the universe can only play out one way. Whatever happens, has always happened, and always will happen, it is unavoidable. The creatures could see their future with absolute certainty, and so they knew that choice is an illusion (or, in my understanding, a mis-connotated word that belongs in the realm of epistemology rather than of metaphysics).

In any case, if the universe experiences this sort of "signature change", then we'll never know it. Consciousness will abruptly cease, like a paused DVD player or a saved Diablo game, waiting forever for time to resume. But, a new sort of consciousness could arise, to which physical movement is the equivalent of temporal progression. Somehow, if it could gather information and then ruminate upon it, by means of movement rather than time, it could become self-aware.

Actually, in a lot of quantum stuff, time is space like already.

Namely - if you see an action in forward and reverse, both make sense. As opposed to macroscopic, where if you show a picture of a man falling from a roof in reverse, most people can tell you its in reverse.

Re:But what does that mean? (1)

The other one was about a kid who befriends a neighbor working in 4-D stuff. The kid (because he's young and has an open mind or something) learns to move about in that dimension as well, and communicate with creatures living in other dimensions. Don't remember the title of that one, thoguh.

Well, when you consider that one second ago is one light-second awa - i.e. abut 300,000 kilometers - then getting to one second ago would be about as difficult as getting to the Moon from Earth...

In other words, we possibly could move about in time "much as we 3D space" - but we don't move around in that all that well, either. At least when compared to the speed of light...

For that matter, a spacelike Time is at least 2 degrees of wierdness beyond what we have now. Right now we're in a 1-dimensional, 1-way Time. Time travel would involve turning Time into a 1-dimensional, 2-way time. The Many Worlds theory is an endless branching-off of different 1-dimensional Times. 2-dimensional, 2-way Time would be, I guess, the ability to switch to any of the Many Worlds in order, and to go backwards and forwards along those timelines. 3-dimensional, 2-way Time, I guess, wouldn't be any different, if you constructed the Many Worlds in 3 dimensions.

xPsi (851544) | more than 6 years ago | (#20913215)

Lets say I told you we had two spatial dimensions. You would imagine a plane with perpendicular x-y axes everyone knows and loves. If I asked you to draw the set of points that were equidistant from the origin, you would probably assume the geometry was Euclidian and would probably instinctively draw a circle (a good guess!). It is commonplace to hear "time is the fourth dimension." As first pass to visualize this, you might try to draw a two dimensional space-time plot: an x axis and a perpendicular time axis in a plane. If I then asked you to draw all the points equidistant from the origin, you would probably again draw a circle in this x-t plane. It seems to make sense, but is only true of time is a "space-like" dimension like "y" in the x-y plane. This is way Newton thought of things and it seems to be what the authors of the paper are advocating. But, unbeknownst to some people who cite "time as the fourth dimension," according to the theory of relativity, the set of equidistant points from the origin on a x-t graph would actually be hyperbole, not circles. This is because in relativity space-time is a Minkowski geometry, not Euclidian. All the weird stuff in special relativity like time dilation and length contraction come about because of this weird geometry. In fancier language, time has an opposite sign than space in the metric. The metric determines how distances are calculated in a given geometry. If time has the same sign as space in the metric, then space-time becomes Euclidian and one would say that time was a space-like. The article is probably extra confusing to non-physics people because most probably didn't know time wasn't space-like to begin with.

When you say "about to" in sports, something generally happens pretty fast.
When you say "about to" in geology, something generally happens pretty slow.
Generally speaking, saying "about to" in cosmology is to geology as geology is to sports.

But not always. At some points in time, the volcano under Yellowstone does go off. Likewise, supernovas happen, and perhaps brane changes too. But to say "about to" or "soon" is just meaningless to human scales of time.

And YOU can profit! (1)

YOU can profit from the coming singularity! Singularity Investor [singularityinvestor.com] has the answer!

Sure, it sounds bad, but with every big change comes winners and losers and you can be one of the winners if you act now!

Oh, wait, that's how to profit from that other singularity...

Does this mean that the universe is going to suddenly go All of an Instant [amazon.com] on us? Because that'd be pretty sweet.

Define "about to"? (5, Insightful)

WibbleOnMars (1129233) | more than 6 years ago | (#20913009)

I'd like to know how they define "about to flip".

Are we talking about something they see as imminent -- could happen at any moment?
Or are we talking about geological time scales -- it'll happen in a few hundred thousand years, give or take?
Or do they mean cosmological scales -- where 'about to happen' means somewhere in the next ten or twenty million years?

Or is the whole question of when a silly thing to ask, given that they're talking about the end of time as sequential/chronological?

It has to be linked (1)

I wonder where the Bible predicts this will happen.

Old, old old news (3, Informative)

bradgoodman (964302) | more than 6 years ago | (#20913075)

This is nothing new at all.

Relativity talks of space and time as a single 4-dimensional 'spacetime'.

M-Theory, Superstrings, p-Branes, and a billion other theories all say there are 10 (or 11) dimensions, including things like two-dimensional "time" and "imaginary-time" dimensions, smaller "curled-up" spacial dimensions, etc.

we are going to transcend into another dimension with the flip... wait ! thats nothing new is it ! "when the mooooon is in the seveenth houuseeee, and jupiteeerr aliiggnss wiiith maaarss"

When the new space dimension appears there will be a land rush!

I can see it now, those people selling land rights on the moon will start taking offers for forth dimensional rights.

The Article (0)

Not that anyone reads them, but due to the slashdotting, here ya go:

It don't get much weirder than this. The universe is about to lose its dimension of time says a group of theoretical astrobods at the University of Salamanca in Spain. And they got the evidence to prove it.

The idea comes from the study of braneworlds: the thinking that the universe we see around us is a 4-dimensional cosmos called a braneworld embedded in a multidimensional universe. The "signature" of our universe is the number of space and time-like dimensions it has: in our case we got 3 space-like dimensions and one time-like dimension. It's what astrobods call a Lorentzian universe. So far so good: lots of astronutters think the same thing.

But our universe may not always have been like this. Some theorists think it may once have had a Euclidean signature meaning that all the dimensions were space-like. Now Marc "Bars" Mars and a few pals in Spain say that the Universe's signature might be about to flip from Lorentzian to Euclidean. In other words, our dimension of time is about turn space-like. Gulp!

This ain't entirely bonkers and here's why. Bars Mars has calculated what it's like to be an observer in a universe that is about to flip and get this: it would look as if it were expanding and accelerating away from us. Sound familiar?

Yep, it's exactly what astrobods have been observin over the last few years, a phenomenon they attribute to dark energy. If Bars Mars is right, dark energy ain't got nothing to do with it and we're all starin' down the barrel of a cosmic catastrophe.

Still, maybe four space-like dimensions will be better than three. Who needs time anyway?

All this talk about time becoming a spatial dimension and realities collapsing is making my brane hurt.

Yeah, I said it.

Is this the break IPv6 needs? (1)

hoopycat (826745) | more than 6 years ago | (#20913223)

All things being equal, this might just be what North America needs to get IPv6 deployment stepped up a notch. I know I'm going to be asking our router vendors whether their IPv6 solution is the key to meeting our customer's demands through the upcoming Euclidean braneworld revolution.

Everyone missed this issue... (1)

The new marklar will not only mean all our marklar's are obsolete, but our marklar's will actually cease to function as well. Marklar told marklar personally that a new marklar is in developement. Should the marklar come to be, a new marklar will be issued to each marklar so other marklar's can tell a marklar from a marklar. Don't you marklars get it?

Nothing to worry about. (1)

After RTFA I quickly delved into the PDF for more information. Now I'm left feeling like I'm the butt of another technobabble [encabulate.com] joke. It's looking more and more like string theory is getting a bit frayed.

Something tells me that no matter how much we all secretly wish for a cataclysmic event of biblical proportions so we can live out our sci-fi fantasies, there just isn't going to be anything that significant to happen over the next few billion years.

Want an adventure? Go outside! The universe is always unfolding as it should, and you get to be a part of it.

I have a rebuttal. (1)

Time doesn't exist? (1)

TheBearBear (1103771) | more than 6 years ago | (#20913349)

I always thought of time as an abstract concept, with no interactions in the real world. Kinda like imaginary numbers. It's useful for us to calculate with, but it doesn't exist as a travel medium or physical medium. You just move around in 3D space thats it. I can't comprehend how you can move through time! I'm most likely wrong cos I'm not a scientist or anything so maybe someone can explain it to me :D.
