Study: Universe could end in 10 billion years
September 18, 2002 Posted: 9:54 AM EDT (1354 GMT)



After the Big Bang, is a fatal contraction inevitable?




--------------------------------------------------------------------------------

By Richard Stenger
CNN

(CNN) -- Stanford University researchers theorize that the universe could experience a cosmic crunch in 10 billion or 20 billion years.

Recent cosmological observations have suggested that the universe will expand at an increasingly rapid rate for at least 100 billion years and perhaps enlarge forever.

But according to a new scientific model, the universe will slow its pace of acceleration and then experience a fatal contraction.

"The universe may be doomed to collapse and disappear. Everything we see now, and at a much larger distance that we cannot see, will collapse into a point smaller than a proton," said Andrei Linde, who conducted the research with Renata Kallosh, his wife and physics colleague at Stanford.

"The standard vision at the moment is that the universe is speeding up, so we were surprised to find that a collapse could happen with such a short amount of time," Linde said.

Linde is one of the pioneers of Inflation theory, an increasingly popular revision of the proposed Big Bang.

First advanced in the 1980s, it suggests that the universe rapidly inflated into a much larger cosmos only a fraction of a moment after it began.

Will the universe expand forever and become cool and dark, collapse into nothingness in a cosmic crunch, or remain in equilibrium between the forces of gravity and expansion?

Inflationary theory predicts a "flat" universe, or one where the competing forces pulling and contracting the universe stay balanced.

The debate, by no means settled among cosmologists, hinges on the role of mysterious and theoretical phenomena known as dark matter and dark energy.

Throw into the mix such notions as string theory, supergravity, extra dimensions and multiple universes, and the question becomes even more muddled.

Yet looking at some of the best work in the field of dark energy, Linde and Kallosh concluded it would change from a positive to a negative force.

Their cosmological model, described in related reports on www.arXiv.org, a Web site sponsored by the National Science Foundation and Cornell University, generated another unexpected prediction: the universe, estimated to be about 14 billion years old, is already middle-aged.

"Physicists have known that dark energy could become negative and the universe could collapse sometime in the distant future, perhaps a trillion years," Linde said. "But now we see that we might be not in the beginning, but in the middle of the life cycle of our universe."

One noted scientist had a lukewarm response to the hypothesis.

"Because their proposal is based on rather specific models and assumptions and their is no current evidence for it, I would say it logically possible, but not compelling," said physicist Paul Steinhardt.

The Princeton University professor helped developed an alternative cosmological theory that proposes that the universe began by colliding with another universe, with both existing in a higher dimensional medium.

"They are only attempting to explain the evolution of the universe between now and the collapse, whereas we showed how this can be embedded in a larger cyclic scenario that leads to an eternal universe," Steinhardt said.

Linde concedes that the work is raw and that astronomy is an inexact science at best, and known for continuous revisions. Recalling an ongoing joke among cosmologists, the Stanford University professor quipped:

"Astrophysicists are always in error but never in doubt."

When i ask this question to my higher self this is the response.

As the universe is expanding a black hole/vortex is developing at its centre and is putting more and more preasure on all matter. the vortex is created due to the increased speed that matter is gaining as it travels through space from the central point, which in turn accelerates and expands the vortex. in ten or twenty billion (17 billion is what i am getting) years the amount of preasure exerted on the matter by the increased speed/size of the vortex will become too great and the universe will begin to quickly collapse. at the moment of zero point/collapse it will quite predictably explode due to a vast influx of energy and the cycle will begin again.

hmmm, makes sense to me.

so basically the universe breathes..?

so one might say that the universe is alive and taking very large, deep breaths ...

yup... the universe breathes...
and when this universe collapses into itself it will rest for 1 eternity and then start all over... take another breath...
that's the reason why we should focus on our breathing when we meditate... or when we have to relax and get back to ourselves

I doubt there will even be a human race left on earth to see that happen.

well, since the sun will expand to ungodly proportions and consume most of the planets in this solar system in nuclear flames in about 5 billion years suppose it dosen't matter how long the universe is going to last. hopefully, we'll all be flying around in other universes by then anyway.

Here's a good one for you:

Because the "big crunch" would be a crunch of the actual dimentions making up the universe, then universe would play out it's history in reverse for the duration of the big crunch. It would then rebound in another big bang and the whole thing happens over again.

Kinda funny, a friend and I were just thinking about this last night.

what will be when all black holes eat the universe, would tehy then eat themselves and leave a nothingness?

Actually the news these days is that the universe will go on expanding forever, because there is not enough matter in the universe to slow down expansion, let alone stop and reverse it.

It is the matter itself that is expanding faster and faster as it travels through space only for the universe to collapse at its centre point outward when it expands to far to sufficiently hold matter together, doesnt get any simpler than that.

The ultimate destiny of our expanding universe depends on how much matter it contains and whether that will be enough to one day stop the expansion. When astronomers count up all the visible matter?the stuff that gives off light?the answer is clearly no. But they have learned over the past several decades that the answer isn?t so cut-and-dried. Observations reveal that vast halos of invisible matter surround galaxies and galaxy clusters. This dark matter adds up to about ten times more mass than the visible stars, gas, and dust seen in galaxies. And there may be more. The inflationary theory, if true, demands that this dark stuff makes up between 90 and 99 percent of the universe. Astronomers have yet to determine what constitutes this dark matter, although some leading candidates go by the names MACHOs, WIMPs, and neutrinos.

Creation and Destruction. It's a part of the cycle. It's happened infinite times before, and it's going to keep happening infinite times.
We are one.

humans cant even predict what will happen tomorrow, why do we believe this?

its all "could" or "maybe". the universe might turn into jello in 10 billion years. or maybe everyone will look like a butt. or maybe all of reality will collapse into a little particle.

everything that lives must die... if the universe is alive, is this how it will die?
