Only 10-20 Billion Years To Go 89
cinorhc writes "An article at Space Flight Now reports on a study of some Stanford researchers that say the universe will collapse in on itself in a mere 10-20 billion years, resulting in "the Big Crunch". That puts us in the middle of the uni's life cycle. The generally accepted theory as of now is the universe will expand forever, leaving isolated galaxies all alone in a nearly infinite sea of darkness. If these guys are right, we should see galaxies blue shift any day now. I personally prefer a universe that will collapse in on itself and then re-Big Bang so to speak, circle of life on a grand scale."

Dresden and Hiroshima being two more consequences to being an asshole...
For the record, the bombing of Dresden was an experiment. Dresden had escaped being bombed up until a few months before Germany's defeat. It didn't have any military targets. It hadn't been considered a military threat. Bombing it didn't have enough military value.
Bombing military bases is considered "counterforce", because the base has weapons that can be used against you. Bombing military barracks is considered "counterforce", because it houses soldiers who could fight against your soldiers. Bombing factories that produced strategically important supplies is similarly "counterforce". Allied strategic bombing during World War II wasn't very accurate. Jacob Bronowski, whose war work was to analyze how successful strategic bombing was, said the average ww2 bomb had a 50% chance of landing within five miles of its target.
So, is bombing the apartment buildings around a strategically important factory "counterforce" or "countervalue"?
Whatever. Dresden didn't qualify. IMO Dresden was terrorism writ large. IMO Dresden was a war crime.
So Dresden provided a perfect experimental subject to answer the question "what happens when you dump enough incendiary bombs to generate a firestorm in a intact city?"
If a fire is large enough, and hot enough, the updraft it generates can be so strong that it causes hurricane force winds to rush towards it, from all directions. Even people in deep bomb shelters in Dresden died. The firestorm consumed all the oxygen, and they suffocated.
The allies had already firestormed Hamburg. But Hamburg had already been bombed up during more conventional attacks. Its streets had been torn up. Fire mains probably required repair. Fire engines and fire stations were damaged or destroyed. So it wasn't a sufficient test of how a city with an intact fire-fighting infrastructure would survive a firestorm.
Because Dresden hadn't been bombed it was more like a peacetime city. Because Dresden hadn't been bombed, bombing it could provide strategic planners with clues as to how to fight world war three. It could provide strategic planners with clues as to how damaging a sneak attack with atomic weapons could prove, after the war was over.
Tokyo too was firestormed.
I believe that Hiroshima and Nagasaki had escaped attack up until the atomic bombs were dropped on them.
So, remind me, who were the assholes in these cases again?

Running from the Big Crunch. (Score:2)
Unfortunately, it doesn't work this way. The collapse of the universe, like its expansion, would involve space itself changing size. You wouldn't be "pulled in"; you'd just see all objects in the universe start falling towards you as the universe itself shrinks.
As the distribution of matter in the universe is nonuniform, some areas would collapse faster than others, but in the end, you'd still be out of luck.
Does anyone know the event horizon for a big bang?
If the universe is "closed" - i.e. if it will collapse to a singularity again - then you could think of it as already being inside its own event horizon. This doesn't have quite the same meaning as with a black hole, though.

We theorize that the majority of stars become black holes when they collapse. They then start to 'eat' all particulate matter and light energy that comes close to them. They are also exxtremely dense, and have extreme gravitational fields, much like that pinhead of matter had before the universe started. So, as black holes run out of things to absorb, might they start absorbing eachother? Then, they would all become one again. One infinantly dense pinhead which would become unstable due to its' own excessive gravitational field and explode again, to create a new universe.

Expansion and collapse of the universe. (Score:2)
Actually, the article's talking about something different.
The idea behind the big bang model is that space itself is expanding, like the surface of a balloon that's being inflated. This drags celestial objects with it, just as spots painted on the balloon's surface will get farther apart as it's inflated.
Now, inflationary theory said that part of the reason the balloon expanded in the first place was that a powerful form of energy filled space at that time, and caused all parts of it to repel each other, stretching it out from an infinitesimal point to something the size of a baseball. After which it more or less just kept going, with space itself continuing to stretch.
Gravity acts to pull space back together again; it's a force that constantly tries to slow down and reverse the expansion of the universe. Not just of the objects in the universe - but the expansion of space itself.
A decade or two ago, it was thought that only the inertia of the expanding universe balanced this. Much measurement went on to see if there was enough matter to cause the universe to collapse. After seeing the effects of dark matter, astronomers figured that there was almost exactly enough matter to keep the universe poised between expansion and collapse forever.
That all changed recently. As far as we can tell now, the universe is still filled with a remnant of the energy from the inflationary period. It or some similar force continues to push the universe apart, stretching space and speeding up the universe's expansion. This substance is called "dark energy". With dark energy in the model, it looked like the universe would keep on expanding forever, eventually leaving us isolated from other galaxies.
The article takes a different view. Calculations suggest that the repulsion of dark energy may fade, and possibly even turn into attraction given enough time. Previous estimates said that it would be thousands of times the current age of the universe before this happened. The authors of the article did their own calculations and say that it could be only 20 billion years.
All sides are hedging their answers, though, as our understanding of the large-scale forces and features of the universe is very tentative and incomplete.

It's important that we pursue it, but we all know that the "current theories" are just working models to help us along, they're almost always disproved and new models are born. It will be along time before we settle into a model that we can believe with some degree of certainty.

Yeah, but in many branches of science, our theories have settled down to some degree, and change as a course of slow refinements (Newtonian physics still works great for most human-sized macro events, for instace - everything afterward merely refines it for small/huge and special cases).
IMHO, theories of the universe are still in their infancy, and every new theory seems to be at complete odds with previous theories, we're still in very much of a guessing game stage without much solidity.
