    Well, there's a problem with being able to describe anything "perfectly" because at a certain point, things don't get any smaller. Also, at that point, there are fundamental limits on what can be known about a given system. There's a slashdotter around here with a sig that says "I have calculated my velocity with such exquisite precision I have no idea where I am." It's a reference to the uncertainty principle, which states that certain pairs of properties of a particle cannot both be known to arbitrary precision. There's also something called quantum indeterminacy, which I don't understand well enough to explain. The short version is knowing everything 'perfectly' is reserved for a higher power, and that there are some things (e.g. all of quantum physics) that you are only going to be able to express as probabilities.

    The idea of the Big Bang is almost ridiculous at a first glance. It's only that it is so logical and well-supported that we hardly think about it. But if you consider all the incredible vastness of the universe, of which the actual visual universe is only a small part(!) and then try to comprehend how everything in it was once contained within an area the size of an electron. At that point (10^-24 seconds after the big bang, if my calculations are correct) it had already increased in size by at least a factor of ~10^20. The mind really cannot comprehend such a thing.

    Context. Hmm. Oh, right, the guy that I replied to was talking about physics.

    You are never going to be able to describe everything You mention that there are certain values of "everything" for which this statement does not hold, but "never" can be variously defined, as well.

    We have theories for describing complex systems, too. You may be confusing being able to describe something with being able to predict its behavior. There are a lot of things that are not predictable even when all the initial factors have been determined and the process is known. There are fundamental limits on what we can know about any given system. That doesn't mean we can't say anything useful about them, though.

    As to how the universe exists, I assume you're asking how everything got started? What came before the big bang, and all that? We don't know anything about that right now, but we're talking about an arbitrarily long distance in the future, so we can probably say that either (1 the information about that event is not contained within the physical universe and therefore nothing about it can be proven (2 the information about that event exists within the universe or can be inferred from its structure, so that it will likely be described by someone at some point, assuming that we continue to exist and study the universe and keep expanding what we know about it.

    So if they're losing mass into some other universe, how come they aren't losing mass? Follow it along a little. You have a small black hole, losing mass at a slow rate (by means other than Hawking radiation). Does it lose mass at a fixed rate no matter what? That seems like an error related to what the article is talking about. So assume that the rate of loss is variant with the mass of the black hole. Probably that would place an upper limit on the size of a black hole. Given that the current record holder is some 18 billion solar masses, that suggests that any such 'draining' effect is small enough to have no real effect. So having a theory that says that "x happens, but is not detectable," it makes sense to exclude it from your calculations until there's some clear supporting evidence.

    Not "drop the laws of physics" in reference to the big bang. Just consider it a known unknown. We can theorize to a point, and beyond that we are limited at what we can discover. There's no way to recreate those conditions, you understand. But if you're using that to cast doubt on the Big Bang theory, well...let me put it this way: your radical ideas have already occurred to others. The Big Bang theory is still the best model that fits our observations.

    No, you really have no idea what you're talking about. Zero. Zilch. You didn't make up the stuff about the Devil's Triangle, big fucking deal. Just because some crackpot says crackpot things on a History Channel documentary, does not mean that the hypothesis is credible or that it deserves any sort of serious discussion. Yes, I saw that show too. The only "scientist" they had was one John Hutchison; for some reason they thought he had a doctorate. Mr. Hutchison is chiefly noted for his claims to have violated the laws of physics to produce perpetual motion and antigravity. I've never been more irate about a television show than when I saw that steaming pile of tripe presented as a documentary.

    Black holes and white ones look the same to an outside observer. You don't get something that spews out matter randomly--violation of thermodynamics. Wormholes (required for white holes to exist) aren't stable, they're just a solution to an equation and for all practical purpose don't exist. There are size limitations on black holes. If there was a black or white hole on Earth we would not be having this discussion right now.

    Now, when someone tells you your ideas are not worth talking about, before you start repeating yourself, perhaps you should double-check your sources. I'm going to keep my clue-by-four here just in case.

    There may be more to life, but there's not a whole lot more to science. And, if science describes the physical universe, any subsequent mysteries after the end of science would be about---what, exactly? I had engineering challenges in mind when I said that the end of science would be boring.

You can go read about it and everything, and look at pictures, and it's real.

    Singularities != black holes. Apparently. Black holes are those big non-radiating things that we've observed in a roundabout way for quite some time now. The idea that an object can be massive enough for light to not be able to escape it has not been undermined. This is just discussing what happens after the matter falls in to the large, tremendously massive, mostly-nonradiating object.
