Universe Shaped Like A Soccer Ball?

Rabid Rob writes "According to a New Scientist article, and prompted by data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), it's suggested the universe could be shaped like a soccer ball - the 'cosmic microwave background' has fluctuations, and a possible conclusion is that 'our Universe seems like an endlessly repeating set of dodecahedrons.' Oh yeah, the universe is only 70 billion light years across, so better buy up the real estate now while it's still cheap!" The NYT has more information (free reg. req.) on this theory, which is quickly being refuted by Wernstrom-like rival researchers.

      Imagine a square sheet of rubber (so we can stretch, bend as we like). It has a finite area, and four edges. We choose one edge and glue it to its opposite edge. Now if you start from one point and draw a line in the right direction, you'll get back to where you started. Otherwise you'll just spiral around until you hit an edge.

      Now we take the two circular edges and we glue them together, giving a donut (a torus). Now if you go in [what you see as] a straight line in any direction, you'll never reach an edge. The surface of the donut doesn't have any sides in the way the original sheet of rubber did, but it still covers a finite area.

      N.b. The problem with this example is that it's difficult to think of just the surface of the donut, without imagining it being 'in' some larger space such as the 3D world.

      Now if you want a headache, try to imagine doing this starting not with a square, but rather a cube, and joining opposing faces together. The first pair is easy - you get a sort of square donut shape. The second pair gives you a donut with an inner donut removed - something like the inner tube in a tyre.

      The third one is the real bugger - you have to imagine joining the inner surface of the tube to the outer one, without going through the tube. I've seen a video that included a representation of what a similar manouvre (sp?) would look like in the 3D world that the cube started in, and I still can't fully get my head around it.

You can define all the essential properties of a toroidal space (for example) without any reference to an "outside" space in which it is embedded. The assumption of embedding is just an extrapolation of our extremely limited experience of living in a 3-d space.

Accoring to both classical and quantum physics, physical space and momentum space are complementary views of reality; neither is more valid than the other. But the momentum space of waves in a regular 3D lattice is indeed a 3D closed space: any wave momentum greater than a certain value in the momentum is remapped to another portion of the space. But there's no 4D momentum space in which these waves are embedded. (OK, you can consider energy as the momentum equivalent of time to build up a 4-d space, but then you hit the buffers -- there's nothing for that 4-d space to be embedded in).

Newton, Darwin, Einstein, Planck: each revolutionised science by rejecting "common sense" and instead adopting an (initially) unintuitive approach that actually fits the facts.

      Ultimately, your argument is a lot like the argument for the existence of the ether: "in our experience, waves can only move through a substance. therefore there must be a substance through which light waves move". Of course, no-one ever found any evidence for the existence of the ether, and eventually Einstein proposed doing away with the idea altogether.

      The authors of the paper claiming the universe is closed claim that this explanation fits better with observations than an infinite universe, so let's assume for now it's true.

Likewise when an old idea fails, science doesn't worry about the failure, but just tries to fix it. Individuals will care, buy science doesn't. Both cases are expected and the processes will take care of the consequences.

In the first example there was a time when we believed, by the observation of water and sound and radio waves, that all waves needed matter to travel though. Therefore light must have something to travel through and that something was called aether. That was disproven in the late 19th century by michelson-morley. This had great ramifications on science, and many people tried to disprove it. Ultimately the aether was disproven, science adapted, and we survived.

      A few years later Planck was trying to figure our why certain equations predicted infinities where infinities did not and reasonable could not exist. He postulated quantized energy, which lead to the extremely uncomfortable random universe in which science currently theorizes. In fact we see that life seems to be pretty deterministic, so science had to come up with a way to make quantum mechanics deterministic at the macroscopic level, and it did. Note that science did not try to change quantum mechanics to fit our assumptions that the world is deterministic.

      Then we come to old Einstein, who had beliefs about everything. He believe that Maxwell's equations were ugly. He believed that quantum mechanics (QM) was deeply flawed. Both of these beliefs served science well. The first lead to special relativity and the realization that newtonian mechanics was flawed, and it's domain had to be restricted to what we call non-relativistic domains. The second lead to some of the work that gives us confidence in the validity of QM.

Russell Humphreys, in his book Starlight and Time: Solving the Puzzle of Distant Starlight in a Young Universe, implicitly recognizes the strong observational support for the cosmic distance scale, and for the initial big bang model. He tries to reconcile this with a 6000 year old universe by appealing to general relativity in a remodeled cosmology. It is, so far as I know, the first serious attempt to deal with cosmological reality in a young-earth framework (this does not mean I think he is likely to be right, only that I accept that he is making a serious try at real science)." This is not particularily positive especially as Humphreys' work moves up a peg simply by going against earlier creationists' efforts to deny the Big Bang theory outright.

      The second: talkorigins feedback 2003: "The major problem I see with Humphreys' cosmology is that it is impossible, if one sticks to the laws of physics as we know them. This weakness Humphreys readily acknowledges, although to him it is a strength. Humphreys refers to Isaiah 40:22, Who stretches out the heavans like a curtain, and spreads them out like a tent to Dwell in. To Humphreys, this is an indication that God side-stepped the laws of physics, to drag space-time out of its own black hole and force the universe to expand, in what Humphreys calls a "white hole cosmology". The need for devine intervention comes about because Humphrey's assumes a bounded universe with a distinct center, both of which are aspects absent from standard cosmology. Standard Big Bang cosmology does not violate the laws of physics, simply because it is unbounded. Humphreys' cosmology does violate the laws of physics, simply because it is bounded. It's a clever idea that relies on direct, devine intervention, in order for the universe as we know it to exist at all." This, on the other hand, is completely hostile.

That is, that the space is all around us and that the matter moves relative to this space. General relativity's view is (again, as far as I can tell) that space and matter (more accurately energy) are bound together, space is *a result of the presence* of energy and acted on by it, curving it. The geometry of space in turn has an effect on the matter by virtue of its curvature, telling it how to move, which is what we call gravity.

      Space in this way is an active part of the universe, not just a way of describing where the matter is. From this viewpoint there is no "outside" as space itself is a result of energy being present in the universe.

And two light paths starting from the same point should never intersect. (Of course, I am ignoring gravitation effects of GR here. Just talking about a plain ole' empty universe)

      On the other hand, if X is a torus (think the surface of a donut, or bagel, or inner tube), then the paths you can take becomes more interesting: you can go "around" the universe in two different routes which, unlike in the case of the sphere, will not intersect each other.

      So my friend, it makes a heck of a lot of a difference what the universe "looks like".

    if the universe is finite, and multiple universes can't interact, then string theory and gravity being a 4+ dimensional force (accounting for its perceived weakness compared to nuclear and electromagnetic forces) are pretty much out the window.

    and in my opinion that's a pretty huge step -backwards- for our understanding, since quite a bit of research has been done with those theories as a foundation.

    not to mention, if the universe is a finite, closed system, then entropy will slowly fill it entirely and definitively end it. (at least with regards to us)

    sure, in the long run if this holds up it'd be a positive step for understanding - any discovery would be. but the immediate effect and implications would be profoundly negative.

    Deductive logic takes general principles (which can be arbitrary but are usually assumed for some purpose) and from those, using the rules of deductive logic, more, subsidary principles arise; contrariwise, inductive logic lakes many observations and from those particulars, the general principle governing them is induced. This means that a deductively valid argument cannot go from true assumptions to false conclusions (which is simply not the case for an inductively valid argument). Thus if science used deductive logic, we would never need to revise our scientific theories. In other words, fundamentalism actually uses deductive research and empirical science uses inductive research, so from a purely logical point of view, a fundamentalist whose arguments were deductively valid would be better than any scientists' argument. If you don't like your own example of fundamentalism, mathematics is also a deductive field.

In other words, it too can't go from a true premise to a false conclusion, but it actually uses information about the world to try to arrive at true conclusions.

      Science is definitively inductive in nature.

      The whole methodology of science is based around the principle of inference to the best explanation. Every experiment that fails to disprove a theory adds to the inductive base for that belief. When an anomaly arises, it shows that either 1) the data is wrong or misinterpreted or 2) the theory is wrong. Any time a scientist does an experiment, they are attempting either to provide a counterexample to a theory (thus disproving it) or to affirm a hypothesis by adding to the inductive base. At some point, the inductive base may become large enough to grant an individual warrant for belief that the theory is true. That's how science works.

      The closest that science gets to deductive logic is the repeated use of modus tollens to deductively prove that a theory is wrong. Yet also falls under inductive logic, as it is a counter example.

    This really is looking like a gross misunderstanding. Weeks is trying to look for properties of the universe that are testable. He has found that for various interesting topologies and spacetime curvatures it is in principle possible for an observer in the universe to detect that it has interesting (i.e. non-trivial) topology. Whether it is detectable depends on the energy density parameter Omega and even if it is detectable it might not be detectable from every part of the universe.

    So in a sense he has discovered something a bit like a streetlight. If you've lost something small in a dark street then the best place to look is under the streetlight because at least then you might see it. Where there's no lighting there's no point looking because even if it's there you won't see it. Unfortunately the press seems to have interpreted the discovery of the streetlight as a statement of the form "I have found what I'm looking for and it's under the streelight". No, he's really just saying that if it is under the streetlight we'd better look there.

In MY view, telling people what THEIR OWN Holy Book (also) considers "correct behaviour" may not be entirely innocent, but it may encourage them to open their eyes to the entirity of their own religion and not just the passages that fit their own opinions or agendas, e.g. it's OK to say "it's in the Bible" if you want to hate homosexuals, but you're not allowed to stone your wife if you find out she wasn't a virgin. In my view, the proof of almost any religion's falsehood lies exactly in the inpracticality of that religion itself. Perhaps if would be a fallacy to generalize this, but as the child abuse in the Catholic Church has shown, simply the fact that people claim they are "good" or "close to God" or live in/close to the "house of God" does not make them immune to monstrous behaviour.

I did more looking just to be sure, but he still wasn't persuaded. I asked others who knew their stuff, and they all said firewall too, but he *still* wouldn't listen. So I gave up, because there was no way to convince him. A week later he realises that the problem was the firewall.

    That's how I feel when I argue evolution on slashdot. People just won't listen. I'm not at all afraid of getting criticism - what frustrates me is that feeling of banging my head against a brick wall. And there is one particular argument that I think is a *very* powerful testimony against one evolutionary dating method, but every single time the evolutionist comes up with the most inane defences. As an analogy, imagine a building with a door that you have been instructed cannot be opened. You try and are able to open the door. You try to tell others, but they won't believe you, even though you open and close it in front of their eyes - they just quote the instructions saying that the door cannot possibly be opened. That's what I loathe.

    Sometimes I state my own opinions, knowing that I might most likely receive some criticism... I don't mind that.. sometimes I reply, sometimes I don't.

    Right. In this case, I hardly even stated an opinion - but rather a link to someone else's thoughts for those interested. I tried to exercise my right to not reply, as you say you sometimes don't - but then you are telling me that I should.

    I firmly believe that from an explorative point of view, any theory that has as a basis or conclusion that "some guy in the sky did it all" is useless, since the discussion will then shift to "ok, but who made the big guy in the sky".

    It will not be pointed out that it is merely beyond our understanding, but also why. We live in a universe where we have freedom of movement through certain dimensions, but on others our course is inescapably fixed. Any Creator will be outside the bounds of such dimensions, able to manipulate and control them at will. Since our minds are bound up inside these dimensions, how can we possibly understand those things outside them? The dimension I refer primarily to is time. So it's not just a careless argument of "we can't understand that" - there are excellent reasons why. I can provide an analogy if you want to understand it more clearly.

    Off topic - one does not have to be religious to see that homosexuality is unnatural - and also something that nature would select against (creationists do not reject natural selection, a common misunderstanding of evolutionists - scientific american's "15 answers to creationist nonsense" claims we reject natural selection, which we do not).

    I do not believe that the fact that you and I have a different opinion will have an adverse effect on either of our lives, so although I strongly disagree with your opinions, I do wish you good luck in having constructive discussions about them in the future.

    I personally do not believe in aliens. I've seen the chances of evolution occuring, and it's a chance of 0. Especially if the universe is finite (back on topic!). To expect me to believe that this should happen twice in the same universe is just absurd. From a christian perspective, I believe it is possible that God created life on other worlds, but I don't count on it. Anyway, here's the point: because I don't believe in aliens, the question of whether they exist or not is unimportant to me. I think, "well, if they exist then cool, but it really doesn't affect me one way or the other". On the ot

    What do you mean, "unnatural"? It occurs in nature, amost other species. There's nothing in evolutionary theory that says that it should be wiped out of the gene pool, either: many traits that aren't selectively positive stabilize at a minority fraction of the population.


    I've seen the chances of evolution occuring, and it's a chance of 0.


    Nobody knows how to calculate the probability of evolution occurring. You certainly haven't "seen" the chances.

    Well, you descibe the problem with completely different opinions: persons A and B will have an entirely different opinion. Person A will see B as 'blind' and B will see A the same way. Both may be entirely decent and friendly people. Your analogy can be bent in several ways depending on what you find correct. Certainly the "the door cannot be opened" argument can also be used for people who try to prevent people from trying to study nature's workings.

    No, I was telling you that you shouldn't complain when people respond negatively or complain about people having done so in the past. Certainly you do not believe that your point of view is so immensely solid that no possible counterargument can be given? If that's the case, then there is no point in discussing the topic with you at all.

    Off topic - one does not have to be religious to see that homosexuality is unnatural - and also something that nature would select against

    Nope, it happens in nature as well. In fact, it's mostly among the more intelligent species where non-reproductive sexual interactions occur. Even if it did not occur in nature at all, then still it wouldn't be a guideline for what would be "moral" for humans (e.g. I don't walk around naked like most animals do). The fact that YOU cannot understand how two people of the same gender could ever possibly love eachother doesn't mean that their feelings aren't real and inferior to what heterosexual couples are feeling. (Note: no, I'm no homo but I'm not a homo-hater either).

    Are you open at all to the idea that there may NOT be a "creator" at all.. or the idea that your religion (I'm assuming you are religious here) might be fundamentally flawed? I personally see theories of evolution as most likely right now, but I'm not "married" to the idea. I accept that there may be a more fitting theory... but it should be one that gives some "grip" on understanding reality.

    Let us assume that there is actually a Creator that we cannot understand by definition. Ok, fine.. but how will our understanding of the working of nature have progressed then? A theory that says we cannot understand what we were trying to understand doesn't seem very helpful. An entirely valid creationist theory would be that aliens created humans and those aliens were created by an external Creator. After all, the reasoning of that Creator cannot be understood by us so any random action can be attributed to that Creator. Your counter-argument would be that it's "absurd" that this would happen or that "it's just not possible", but.. hey.. wouldn't that make you attempt to understand the Creator? In fact, you cannot disprove any variant on a creationist theory, unless you use religious texts as backup... which brings us to the following point:

    It's the same for questions of creation or religion. When you don't believe it's hard for you to see the importance - but if you ever come to accept our views then you will suddenly see just how critical and life changing they are.

    Okay, so are you telling me that the path YOU followed is the ONLY path the enlightenment? Who are you to tell me that the way I have developed my own views is in any way inferior to yours? I have experienced life-changing (enhancing) developments that might almost be described as spiritual... and they were *entirely* non-religious. It is EXACTLY that kind of arrogance and you-are-blind belittling that is common to organized religion. I accept that different people may have different paths to reaching a state of 'spiritual' contentment. You have convinced yourself that your own path is the only path. There are more doors in my hallway.

    I would make the claim that the main purpose of Creationism is not in fact to provide any workable theory

    I called you deluded because you were confusing bogus science(or at least very poor science) with actual science. Real science doesn't work the way creationist scientists do, however much they claim to be doing real science. I would love to point out the holes in whatever you are personally basing your exact creationist beliefs on, but you refuse to post a link in a public forum. If you are too stubborn to post a link in a public forum, then it's not worth my time. I refuse to email you, because frankly, I prefer not to give out my email address to people I don't know, especially persons who are offended so easily.

I have no more reason to believe the Bible than I do old "fairy-tales" about Zeus sitting on Mount Olympus shooting lightning bolts from his ass. To be fair, I would probably be a little less harsh if I were dealing with someone so primitive they believed that old nonsense, but you're grown up enough to accept what other people really think about your beliefs, no?

    Slashdot is one of the poorest mediums for discussing evolution and creation.

    Why? Because people, not being face-to-face, are more comfortable asking hard questions? Being exposed to a lot of Christian "teaching," I find that Christians often use intimidation as a means of silencing dissent. There is no public discourse among average Christians.

    It doesn't seem to be working well. I think it's just scaring away everyone who is interested; your approach is reminiscient of Scientology... "Let's discuss this in private and I'll let you in on the 'truth.'"

      Sigh. It is not that hard for me to understand that others see the Bible as a work of fiction. It may or may not surprise you that I have been well aware of the fact that people do for many years.

      However, what you have a problem understanding is that it's not really complimentary, and really is insulting, to tell someone to their face that their beliefs are fairy tales. Your exact original words were:
      Why not work forwards from what is observable, instead of backwards from a bunch of fairy-tales?

      That is insulting. You talk as if it is established that these are fairy tales. You did not say "I think they are fairy-tales" - you talked authoritatively as if they are fairy tales. You worked from the supposition that we would both agree these are fairy tales. That is not the way to get someone on your good side. If I say to someone whose beliefs differ to mine "why don't you give up your fairy tales and look at the truth" I am not going to persuade them! They will put up their defences and feel no compulsion to be persuaded. If on the other hand I say "I have some good reasons for not believing what you do", then they are more inclined to listen. Surely you can see that! Your words were not an "I think they're fairy tales", they were "you and I both think these are fairy tales".

      Lets reverse it. I could say "Why don't you let go of your evolutionary fairy tales and look at reality?" - does that work? do you find it persuasive? I think evolution is a fairy tale - so what if we both start accusing each other of listening to fairy tales? Of what does it avail us? It is entirely useless.
