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?

I’m not scared. Why the hell would I be scared about something I can’t do a damn thing about.
I DONT LIKE MONDAYS TELL ME WHY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
meh…. dont expect this to happen anytime soon.
we still have another 500 years before earth gets invaded by real aliens…. *check the buddist manuscripts*
2012 is just the solar storm, yes millions will die….. and this implosion explosion thing is constantly happening, its the very essence of matter itself.
If I told you space was bent, and not a sphere, and that space was flat like a mirror, you could keep traveling to the event horizon, but never reach it.
So work this out, its bent and thinner than paper… yet we are 3 dimensional? but yet holographic projections according to string theory.
if you can work your head around this, and understand it like a few of us, you just disproved the existance of a ‘god’.
…..if you think that this doesnt make sense, I suggest you study string theory, do the math.
it proves god does not exist.
If time becoming space-like is equivalent to an expansion of our perceived universe, when time will complete the transition to space then the universe will become infinitely (or extremely) large: distances between particles will be infinite (or very large) so our bodies won’t exist anymore. We’re going to be stretched to death, but I think we’ll die much before that time (!) because the sun will lose its gravitational grip on Earth and our last days will be very dark and very cold.
But this is nothing new: the scenario of a cold death of the universe is quite old.
To visualize what this transition will be, use Kenny Rogers lyrics from “Just Dropped In”.
I pushed my soul in a deep dark hole and then I followed it in. I watched myself crawlin out as I was crawling in. I got up so tight I couldn’t unwind. I saw so much I broke my mind. I just dropped in to see what condition my condition was in.

We can visualize the spatialization of time by increasing dispersion of light inside of fog with distance. By AWT vacuum is inhomogeneous environment by definition, so that the light travels along the more curved path, perspendicular to spreading direction, the higher distance is. At the sufficient distance, the light travels completelly in perpendicular direction, because it spreads along event horizon of our universe. The perpendicular direction is the space-direction of the space-time gradient.
If time is an intersection of space and energy and time will become simply space then is the “absence” of energy the cause or the effect of this flip? If it is the effect then it will not be an absence but a stationary suspended energy mode of the universe which means time is not the product of the intersection but the cause along with space of the existence of energy.
please explain: does the universe acquire additional dimensions as it expands? Presumably it had zero dimensions at the moment of the big bang, with one spatial dimension and no time. Then, within a very short time it must have become a universe with one spatial dimension and one time dimension, then a 2 dimensional space with time, then the universe we are able to perceive with 3 spatial dimensions and time. presumably this all happened in a very brief instant of time, after which there were 4, 5, n spatial dimensions. Am i just making this up or does it make some sense? forgive me, i am not well read in physics.
Also, am i correct in understanding that the time dimension changes as the observer moves far away from a massive object (like the rest of the universe) so this would perhaps explain time becoming more space-like as the universe expands?
But I would think that perhaps time would only become completely spacelike at the outermost frontier of the universe, and since it is impossible for us to ever go there, time will only approach very close to being spacelike as far as we are concerned and we would never actually reach a point at which it flips (or will only reach that point when the universe starts contracting?)
Does time as we know it only exist as long as the universe expands and what is our experience of time when/if it starts contracting?
also, am i to understand that, if time is at least somewhat spacelike already, somewhere behind us, everything that ever was still exists? this actually is starting to sound meaningless because using the word “exists” implies an incomplete understanding of what time is. I’m so confused….
one more thing…. is it possible that time is the first dimension? Did time have to exist before any of the other dimensions did? Thus the big bang represents a state in which there is only time but no spatial dimensions?
also, if the universe never stops expanding and time becomes ever more space-like, gradually approximating the qualities of a spatial dimension, does that mean we eventually approach, but not reach a state that is completely timeless, AKA eternity?
If it means losing touch with correct spelling, I would blame Bush as well.
Time is only a tool. Only gained constancy with E=MC2. But it is NOT a true entity on it’s own. That’s why Einstein’s tried to fix relativity (which he said was “one of my biggest mistakes”. which then opened the door for Quantum Mech (which also has problems) then String etc… We must make NOTHING, into something, in order to reach Balance. Our mimes are NOT truly capable of comprehending NOTHING! We only live in a 3-D universe no matter what junk math proves. 3rd law of Thermo Dy also limits us. For example: the true speed of Lt (C) does NOT calculate the speed of the Photon except on a linear path; yet we KNOW the distance of the freq(Why /what changes the direction of photon {side-to-side[what energy is lost in the change]} as it move in a linear direction?) & that C changes for gravity, water, leaving grav (HOW if it is truly a Constance) , So since the photon is truly traveling faster than C why doesn’t it’s mass become INFINITE? Why don’t we or everything else explode when hit with Billions of photons per U-sec? Since it is NOT (Constance) why should we be limiting ourselves (because it works in MATH, just a lot of time; SAD & not truth seeking). Most likely Marc “Bars” Mars and a few pals in Spain are in fact proving time does NOT truly EXIST AT ALL. It is simply, only a tool (a screwdriver, 9mm wrench, etc.. Not a Constance) we can use only some instances. Only in the CORRECT instances will it’s purpose provide a correct solution.
Time (progressive sequential rate of change measured relative to the selected observable reference) is known to vary relative to extreme mass.
Mass exists from gravity and generally follows the inverse square rule except outside of broad thresholds.
near-massless particles have unstable time and can be observed to be unprdictable, without ’cause’ and in multiple places at the same instant.
Our normal cause&effect rate of observed change (time) will remain in order as long as it is observed within the mass thresholds (between, say, quantum near-massless and black-holes).
I refer to Time as above because it could easlily run at random speeds (or stop) and we would not be aware, just at the people in a movie that runs slow or fast, are unaware. Only the observer outside is aware.
Our ‘time’ or sequences as oberved fro outside (e.g. from quantum side) may be seen to stop/start speed up or down.
Food for thought
Outstanding article. There’s a lot of good info here, though I did want to let you know something – I am working on Ubuntu with the up-to-date beta of Opera, and the look and feel of your blog is kind of raffish for me. I can understand the articles, but the navigation doesn’t function so great.
Considerably, the article is really the freshest on this worthy topic. I agree with your conclusions and also will thirstily look forward to your forthcoming updates. Saying thanks will certainly not simply be enough, for the enormous lucidity in your writing. I can directly grab your rss feed to stay privy of any updates. Pleasant work and much success in your business endeavors!
