so is it 50% it will and 50% it wont that time could end tomorrow since "there are an infinite number of instances of every possible observation" ?

It just boggles my mind how a species that first shows its footsteps a recent 200000 years ago can even argue such a possibility of a non infinite world.
Its our good fortune that our current climate supports our race - the homosapien race. I don't think it's of any scientific benefit to even speculate on such an event throughout such a time scale where we humans will no longer exist - imvho.
Interesting argument nonetheless.

Who saw that new Futurama time traveling episode?? Maybe that's how the universe works 
seems more like they're postulating that there is a 50% chance it will end before then, 50% chance it will be after then.

Read the articl, MEH, how can something end when it does not exist?
stupid fear mongering scientist don't have a clue.
neither do we, so Fuck them all.
There is only the moment.

A Scientific Heall Motherfugging Yeah to that!!!

That seems to be the only alternative to ending.
If the many worlds cosmology is correct, and as Hawking says, everything that can happen has is and will happen, then it may just play out as an infinite loop to those of us unable to navigate any of the higher dimensions... something to ponder.
If time did not exist you could not perceive the moment.
I think it's safe to say that Einsteins time warp theory in space proves time to work on a completely different realm. This genuinely raises the possibility that time in space may be infinite. Where it breaks from our reality in time is left for the scholars to determine.

also theories don't prove anything, they show what is probable.
M-theorists might argue with those conclusions of yours.
but did not Einstein theorize that time and space were directly relative, anyhow?
Thank you bro I'll definitely read up on that text. Here's a link http://www.livescience.com/space/scienceastronomy/070827_star_warp.html
Einsteins theory is already being recognized in real time on a star. If time is warped around this star then time in itself is misunderstood. This means that time for you on this neutron star would differ than time for me on earth.
Given this information and the lack-thereof would mean our understanding of time is no different then our understanding of our existence.
This would make the argument of these respected scientists null.. Don't you think?

Not yet, but I'll dig deeper and find out If I think that, and either way I'll tell you why I think what I think.
Thank you brother. I too will dive into that text and see where it stands in my opinion. Smoke a fat one for me. I'll toke on some G13 for you.
thanks. when i run across cool stuff to share, i enjoy sharing it.

The team's proposal, published in the journal Physical Review D, dismisses dark energy as fiction. Instead, Senovilla says, the appearance of acceleration is caused by time itself gradually slowing down, like a clock with a run-down battery.
“We do not say that the expansion of the universe itself is an illusion," he explains. "What we say it may be an illusion is the acceleration of this expansion - that is, the possibility that the expansion is, and has been, increasing its rate."
If time gradually slows "but we naively kept using our equations to derive the changes of the expansion with respect of 'a standard flow of time', then the simple models that we have constructed in our paper show that an "effective accelerated rate of the expansion" takes place."
Currently, astronomers are able to discern the expansion speed of the universe using the so-called "red shift" technique. This technique relies on the understanding that stars moving away appear redder in color than ones moving towards us. Scientists look for supernovae of certain types that provide a sort of benchmark. However, the accuracy of these measurements depends on time remaining invariable throughout the universe. If time is slowing down, according to this new theory, our solitary time dimension is slowly turning into a new space dimension. Therefore the far-distant, ancient stars seen by cosmologists would from our perspective, look as though they were accelerating.
"Our calculations show that we would think that the expansion of the universe is accelerating," says Prof Senovilla. The theory bases it’s idea on one particular variant of superstring theory, in which our universe is confined to the surface of a membrane, or brane, floating in a higher-dimensional space, known as the "bulk". In billions of years, time would cease to be time altogether.
"Then everything will be frozen, like a snapshot of one instant, forever," Senovilla told New Scientist magazine. "Our planet will be long gone by then."
Though radical and in many way unprecedented, these ideas are not without support. Gary Gibbons, a cosmologist at Cambridge University, say the concept has merit. "We believe that time emerged during the Big Bang, and if time can emerge, it can also disappear - that's just the reverse effect."

That was an excellent read
I also find it to be scientifically sound. You certainly picked a sweet one.

Now José Senovilla at the University of the Basque Country in Bilbao, Spain, and his colleagues have a radical answer - we are fooled into thinking that the expansion of the universe is accelerating, because time itself is slowing down.
Senovilla's work, which will appear in Physical Review D, is based on speculative string theory models in which our universe is confined to the surface of a membrane, or brane, floating in a higher-dimensional space known as the "bulk". String theorists have used such models to explain why gravity seems to be so weak in comparison with other forces; in these scenarios, gravity is the only force that can move between branes and leak into the bulk.
Although our brane contains three spatial dimensions and one time dimension, there is no law saying that all branes floating in the bulk must have this same "signature", says Senovilla. Other branes could have no time dimensions, or even two or more. What's more, the branes could swing between different signatures, with time dimensions switching to space dimensions and vice versa.
Senovilla and his colleagues wanted to know how we would interpret such a change of signature - with time changing to space, say - if it ever happened on our brane. His calculations showed that such a transition would appear to be a smooth change, with "brane-time" gradually slowing down relative to "bulk-time" until it finally disappears and the brane gets its extra spatial dimension. This would have dramatic consequences for the brane and everything in it.
"If this is really happening, we would start by experiencing things that we just cannot explain," says Senovilla. Time in the bulk will run at the same rate as always, but clocks in our brane will tick increasingly slowly relative to bulk time. Because we aren't aware of this, when we calculate the speed at which things are moving, it would appear that they are gradually moving faster.
Although everyday events may quicken, the effects would be imperceptible. Senovilla thinks we'd get the first clear hint that something was amiss from measurements on cosmological scales, where astronomers have been gauging how the universe has changed over billions of years.
"Our calculations show that we would think that the expansion of the universe is accelerating," says Senovilla. "[Any] observation of dark energy could be evidence that our brane is changing signature and that time is disappearing," he adds.
In the 1990s, astronomers measured the relative movement of similar supernovae from different eras in the history of the universe. They inferred this motion by looking at the frequency of light emitted from the supernovae at various distances from the Earth. However, the measurement of frequency depends on our perception of time so their results may have been skewed, leading to the "false" view that things are moving faster, says Senovilla.
It may seem like an extravagant solution to the problem of dark energy but Senovilla argues that, unlike other attempts at solving the mystery, he does not need to invoke any exotic particles or new forms of energy.
If he is correct, things will seem to get faster and faster until time finally disappears. "Then everything will be frozen, like a snapshot of one instant, forever," he says. The good news is that we needn't worry that time will disappear in our lifetime. The team have calculated that even if it is already happening, time wouldn't freeze for billions of years. "Our planet will be long gone by then," says Senovilla. "It is only the poor brane that will feel the effects."
Gary Gibbons, a cosmologist at the University of Cambridge, likes the idea. "We believe that time emerged during the big bang, and if time can emerge, it can also disappear - that's just the reverse effect," he says.
Gibbons says the team's work gives us new insight into brane dynamics. "It's intriguing to think that if you're confined to the brane, you see things from a very different perspective, and we could mistake a change of signature for dark energy," he says.
Whether this is a realistic explanation for dark energy is another question. Gibbons would like the team to make other, testable predictions to back up their idea. "Until then, we can't say that it is happening, but we can at least say that it could be," he says.
