I stand corrected. (Our theater was only equipped with DTS.)
Incidentally, I saw the movie last night (and reviewed it here). The problems described above didn't happen, but the place they are described as starting the the beginning of the last reel of the movie. I'm guessing they had problems making enough copies, as the theater I was at had to delay our 8:30 screening until 9:00, and the 9:00 show was moved to the theater next door. This is a pretty definite sign that they only received one print but were expecting two, and were forced to run the shows in tandem.
All digital sound if off the print. The film contains the information for two channel stereo, and may contain some cues to help out SRS. DTS, SDDS, and Dolby Digital use off-film CD media. There are some non-digital four channel formats that are on the film itself out there, but they are usually magnetic strips on a 70mm print.
It is not uncommon for a film produced in massive quantities such as this to have sound problems. Expect replacement sound media to be out within a week, if that is, in fact, the problem.
I used to work as a projectionist for Landmark Cinemas, if anybody cares.
Mathematics is the only science which can prove things in any absolute sense, because it does not depend on experimental results. The theories in any experimental science are only as good as the limits on the accuracy of the experiments. A prime example is Newton's laws: they looked like they were completely true when they were written down and published, but we know now that they are only slightly wrong when dealing with things roughly the size and speed of people, and grossly inadequate when dealing with really high energy objects. To paraphrase the original poster, experimental sciences cannot distinguish between "right" and "wrong," they can only distinguish between "wrong" and "not very wrong."
Complete BS, huh? Have you read the papers you can find here, here, and other places not on the first page of results on a Google search. Maybe I should have mentioned that speed wasn't the only concern, but it was the prime concern. In any event, I've got evidence to back up what I said. You?
That data rate doesn't apply to the analysis stage. Magnetic media can't keep up with the data as it comes in, so it has to be sifted through in a first pass to eliminate the boring cases. (These would be the times two particles passed each other in the detector without colliding, and things like that.) Most of the analysis is done later on. (In fact, the analysis I'm doing today is on data collected in August 2000.)
The data figure stated above is at the actual data collection stage, not the anlysis stage, so it's not being transmitted via ethernet. The project I'm working on (ATLAS, which should be running on the LHC when it gets built in the next few years) has actually found that magnetic media cannot keep up with the data rate, so they had to figure out another means of storing the data while they were sorting it between particle bursts. They decided on a switched capacitor array, since that can keep up. The data actually goes through (IIRC) three stages of analysis before it's finally approved and recorded indefinitely. This filtered data is the stuff that will be transmitted via the Grid.
One more perk to add to Suidae's post; there are a lot of useful spin-off technologies to any science on this scale. For example, the World Wide Web we're using right now was designed at CERN to allow a fast and easy way to exchange the data collected at that particle accelerator.
Why is this inappropriate? They are emergency numbers and should presumably be distributed as widely as possible in order that those who need them are
aware of what they are.
That was the person who started this thread. The person you responded to is talking about the insensitive nimrod who decided it would be funny to post a joke combining today's tragedy with "All your base are belong to us."

That's right, folks, if this collider can't find a Higgs, that means SUSY is just plain Wrong
In a word, no. These energies were reached a long time ago, but the lack of a Higgs is not surprising. Remember that the Higgs is never produced alone, and that other particles produced need energy too. You need a center of mass energy on the order of a few TeV before you look for the Higgs.
Louis Wu is described as being in the same physical condition of a man of 20, not necessarily looking 20 years old. He's also described as a person with no real racial traits left as the genes were diluted, but he shows a preference for the Asian appearance through the use of a single long braid on the back of his head as his only visible hair, and the use of body makeup to give his skin a slightly yellower tone and narrowed eyes. I reread the novel a few weeks ago after hearing the news of the movie, and Chow Yun Fat seems to fit the descriptions listed.
That clause would most likely backfire, and wouldn't be as effective as some might think. Many, many movies are already using Linux for special effects, so that wouldn't impact Kodak. Those that use Windows might just decide to succumb to the digital camera technology that is being used for the next Star Wars movie, and a few TV shows now. Kodak is already in trouble on the movie front, since film-free digital cameras are on the way. I think their best bet is to develop these digital cameras and help build them to work with the special effects software currently available on MacOS and Linux. That could help swing the big Hollywood players against Microsoft. Studios don't have a lot of political and financial power, but some of their parent companies do.

> This leaves you with a singularity that exploded

I can't tell you if it had a reason for existance, but it may be possible to explain why a singluarity exploded. (That whole "where did it come from" question cannot be answered by science: a singularity destroys almost all information about what it was made of. All you can possibly know about what a black hole as absorbed are the total mass, and net charge and angular momentum of what it swallowed. You need the "God did it" method if you demand an answer to that question.)
Stephen Hawking has shown that the particle-antiparticle pairs that are perpetually being created in all of space (according to the current models) can provide a mechanism for a black hole to lose mass and energy. To explain how, we first must relax the conservation of energy by incorporating the results of quantum mechanics.
In high school, you were taught that energy can neither be created nor destroyed, only transformed. Well, this is mostly true. Conservation of energy can be violated, provided that violation can never be observed. The Heisenberg Uncertainty Principle of quantum mechanics puts limits on our observations. (Our uncertainty in the energy of a particle, multiplied by our uncertainty in the time we spend measuring it must be no smaller than an amazingly small number, Plank's constant h divided by 4pi.) The Universe can violate energy conservation, provided that excess energy is gone so fast it cannot be observed.
The Universe, therefore, is able to conjure up a particle and its antiparticle anytime, anywhere. The creation of these particles is referred to as vaccum fluctuations. Anyway, these particles can be produced near a black hole.
What happens if one of these particles falls into the black hole, while the other has enough energy to escape? Well, if you do the math, you find that in some cases, the particle that escaped can survive indefinitely; it can behave exactly as if it were a real particle.
What effect does this have on the black hole? The net effect is a loss of energy. Because of mass energy equivalence, this corresponds to a loss of mass. In effect, the particle that escaped is behaving as though it had escpaed the black hole. If this happens often enough, a black hole can reach a point where it no longer meets the requirements of mass and density to be a black hole.
What happens then? Well, nobody really knows. There are a lot of theories, including a Big-Bang type explosion. The one point I feel I should note is that, if this were a Big Bang sort of situation, then there would be matter in the Universe outside the singularity before it exploded. I'm still not sure how much matter this would be. I also don't know what kind of timescales it requires; if it's fast enough, it may appear as though it were a single explosion.
This may not be the answer you're looking for, but I hope I convinced you that answers are possible when you're asking what triggered the Big Bang.
Why do you need a purpose? The "purposes" you list for other discoveries seem like they were concocted after the fact to justify it for people who prefer to believe in a supreme being guiding the Universe.
If you really need a purpose, here's one: to provide us with a challenge. If the Universe continues to expand indefinitely, there will be a time when the average density of the Universe is low enough that the formation of news stars becomes unlikely, and the fuel for those stars will begin to be burned up. Survival of the human race will be almost impossible in those conditions. The fight to survive will be the last remaining challenge for a race that will have had more than enough time to uncover a set of physical laws that describe the Universe. We'll need something to do.
I think I wasn't clear enough; I was picturing two planets with different orbital radii and the same period. That's not possible. If the orbital radii are the same (or similar enough with slightly different eccentricities in the ellipses) then they could have the same orbital period. The chances of this happening are probably pretty slim, but there's a lot of stars out there...
You are right; the former is impossible. The period of the orbit can be calculated using only the mass of the Star and the average orbital radius. The "linked" orbits comment refers to orbits with a small integer ratio of orbital periods. In this case, the length of a year on one planet is exactly double the length of the year on another.

It's a reference to "Ringworld," by Larry Niven. It's a great book; I tell everybody that they should read it if they get the chance.
