      Why I can't I get a date?

      I feel ya man. It's hard to comprehend the reason for asking if we are alone in the universe when in fact many of us are alone in our own lives. The limits of conventional computing seem more finite when you realize that computers are more or less just conduits to other people who are alone as well. Questions about "cooperative behavior" and "quantum uncertainty" seem only to pick at the withering soul drowning in the sea of loneliness.

      It might seem to be an easy one, but your answer doesn't explain most cooperation.

      Cooperative behavior arises out of an evolutionary phenonemon known as kin selection [wikipedia.org]. The basic idea is that if you are related to another organism, you know that you are likely to share some portion of your genes. Thus, it's in your interest to assist your relative in surving to reproduce so that your shared genes are passed down.

    Ultruism, while not a human specific trait, IIRC, Orcas will give their lives for the lives of other pod members, ultruism, as practised by our kinds is difficult to jive with the tenents of evolution. There have been attempts to define ultruism in terms of the mainstream theory of evolution, I know S. Gould took a stab at it in his seminal book The Structure of Evolutionary Theory [amazon.com] and Unto Others The Evolution and Psychology of Unselfish Behavior [harvard.edu] by Elliott Sober, David Sloan Wilson, represents another attempt, but the bottom line is there is no clear answer (which explains why it's on the list :)).

    Generally answers seem to cluster around the idea of kinship and the furthering of an individuals gene pool.Perhaps the answer will come in tandem with the solution to another evolutionary riddle pertaining to our kind, why is it we have such relatively small canines? The males of most primate species have large canines especially for fighting, usually other males in order to win controll of groups of females. Some speculation has it that monogamy in our kind did away with the need for large canines, or maybe, in our kind females did away with the male perrogative of controlling breeding?

    • The idea of ultuism being tied to kinship has ties into the idea that our relatively, large brain developed to handle our complex social relationships.

    My favourite is why does time have an arrow? This is closely related to one of the listed questions "why is time different from the other dimensions?"

    Or to put it another way: Why does the entropy of any closed system always increase? Why do we take the 'causal' solution to Maxwell's equations when determining the field generated by an accelerating charge? Why does the evolution of a quantum system appear to involve an irreversible step - wavefunction collapse? These may in fact be the same question in different guises. I think it's the number one question in physics. Every fundamental law of physics has time reversal symmetry (or at least CPT symmetry) and 'future' and 'past' look as similar as 'left' and 'right' at a fundamental level. So the arrow of time we see so blatantly around us is in serious need of explanation. It's almost as if physicists live in denial about the fact that their fundamental theories clearly just don't seem to match up with reality. But there are some good books on the subject such as Zeh [amazon.com]'s.

      The arrow of time is a curious one. For photons, time must actually be frozen, as relativistic time at the speed of light is zero - even so, photons clearly experience events, otherwise there would be no photoelectic effect and the world would suddenly seem a lot darker - mostly because eyes wouldn't work.


      Now, this is only in relation to someone INSIDE the Universe. Someone from an external frame of reference (if such a concept exists) would see the entire of space/time as a single four-dimensional entity. There would be no "time", because time is a product of being on the inside of the system.


      This seems to answer the question. Your position along the time axis of space/time is your position relative to event zero, along the time axis. The Universe only expands, so the time arrow can only face outwards.


      Problem. Steven Hawking demonstrated that if the Universe were to contract, entropy would STILL increase on any kind of scale. In other words, there would still be some measure (which we can call time if we like) which can ONLY increase, never decrease.


      This complicates the picture, because if time can only increase (even when the Universe is contracting), then time is NOT a simple linear measure. Ok, then what is it? Well, simple logic suggests an answer, but simple logic can be wrong. The suggested answer involves taking the absolute value, which must always be positive.


      However, you can't just throw away the sign of a number and leave it at that, there has to be some reason why you would do this. Let us say that real time is, in fact, TWO dimemsional, and that the time we experience is along a vector in that space. Well, the length of a 2D vector can be calculated quite easily. Treat the end-point as a complex number and take the absolute value.


      Now, treating time as a two dimensional entity raises its own problems. Why two? Why not three? Or four? In fact, this leads me back to another post I did a while back, relating space and time as vectors, when discussing relativity.


      Let us treat space/time as a single four dimensional entity. A plain, ordinary four dimensional entity. Nothing special about any of the dimensions, nothing unique, nothing out of the ordinary - other than being four dimensional.


      Now, if subjective time is plotted as the vector we are travelling along in this 4D space/time system, then subjective time is (again) the absolute value of that vector and must always be positive as a result, regardless of the behaviour of "physical" time.


      Ok, does it make sense to regard subjective time as the vector we are travelling in? That one, I can't answer, but a very superficial glance would indicate that it would seem logical enough. The vector indicates a speed of some sort, so why not the speed of subjective time?

      • Once you're using tensor analysis [wikipedia.org] for your physics and engineering homework space/time is a four-dimensional vector. IIRC the spatial dimensions are real, the temporal dimension is imaginary.

      If you're interested in the physics questions you can cut out the journalistic middle-men and read John Baez's Open Questions in Physics [ucr.edu]. I found it informative, entertaining, and for the most part comprehensible to a moderately well informed non-physicist.

    The article on why humans have so few genes [sciencemag.org] does some nice hand-waving but fails to answer the core question. Sure, the genome can do some interesting combinatoric stuff to get more out of a given length of DNA, but that does not answer the question -- why should humans have fewer genes than something so simple as a mustard plant or rice?

    I suspect the answer is related to human (mammalian) mobility and thermoregulation. If a rice plant gets stuck in a hot place, all it can do is use a different part of its genome to make proteins suited for hotter weather. In contrast, people can move out of the sun while their body basically maintains a constant temperature. Similarly if the plant faces too much cold, too much water, too little water, to much sun, too little sun, too much salt, etc. it can do nothing but sit there and hopefully pull something out of its genome that can cope.

    The point is that plants must adapt to whatever their environment gives them much more so than humans. Human mobility and the ability to modify its environment means it is less reliant on gene-based adaptability.

      I would guess that we have so few protein-encoding genes because we have a large amount of non-protein-based regulatory machinery. In particular, the study of RNA-based regulation in mammals has exploded in the past few years, and it looks like a huge amount of regulation takes place without proteins. I would bet that many of the things which are done crudely in plants with proteins are done in extremely complicated fashions with RNA-based regulation in mammals. That isn't to say that proteins aren't involved; rather, I expect that we can get much more use out of a single protein when that protein's behaivor is affected by RNA in the cell.

That seems backwards, but think about - plants have to have everything they do hard-coded into their genes. Therefore, they must have all sorts of conditions and exceptions in their genes to survive changing environments, and their existence is just the playing out of those genes. However, humans more than most animals, can learn and think.

      Would it be possible to tell (even an educated guess) from a creatures genome, whether or not that genome had been subject to engineering at some point in its ancestry?

      What is the nature and origin of the Universe?

      It is and has been. (seriously, that's all the answer there is).

      What existed before our universe?

      Unknowable. "Before" the universe began is "before" the concept of time has any meaning. Alternatively, if we could observe things that were "outside of the universe", we would have to expand the scope of the universe to include those observations, meaning that they were no longer "outside of the universe".

      What is the original nature of existence...of what we call "reality"?

      This is a vague question. One possible interpretation is that you're asking about the "super-universe" in a different way from the "before the universe" question. It has the same problems as the "before the universe" question (if we could know, we'd have to redefine the universe).

      The other interpretation is that you're asking if the nature of reality has changed through the lifecycle of the observable universe, presumably though alterations of fundamental laws from some initial "ideal" state. This question, while clearly less "grand", is more relevant, because it offers a source of falsifiable assertions and possible experiments.

      Being able to classify questions as "irrelevant" and "not answerable" for various reasons is a part of "knowing what you don't know" and the rather tricky subset, "knowing what you can't know". Wisdom (and a lot of saved time) lies in a deeper understanding of how to determine the value of questions.

      I must admit that about 12 years ago, I got comfortable with saying "I don't know" along with the realization that people are capable of asking bad questions as if they were the most important questions around. My favorite is "Why are we here?" It's worthless because it begs about four other questions that have no objective answer.

      The interesting form of the question is, "Why am I here?" and it can only be conclusively answered by exactly one person: the same person who asked the question. What's really tragic is how many people are afraid of answering it themselves and accept someone else's answer out of fear of "getting it wrong". *sigh*

If transparency were a function of molecular alignment, water would be black or white, and diamonds and other crystals would only let light through at certain angles.

    • "The US is the world's largest grower of corn. It can provide enough *biodiesel* for the entire US and then some. The oil cartels and the politicans (e.g. Bush) who have alot to lose if we switch to biodiesel fear this"

      Maybe someone can convince Dubbya that they could turn rainforests into biodiesel.

      But then countries like Brazil, Indonesia and Congo would end up in the same position as the gulf states today and US foreign policy would be *right* back where it started...

    Are we alone? Almost certainly not; there's no reason it should have happened here and not elsewhere in this insanely large universe. Will we ever find out? Maybe not... how many technologically sophisticated cultures are there actively broadcasting their presence, in the wavelengths we're watching, close enough that we can hear them?

    Dark matter and the biological basis of consciousness are well below the big question: What is knowledge? What is consciousness, and what is truth? This should be answered before the question of what the biological basis of consciousness can be known. We don't even know what consciousness is, so why do we look for its biological basis first?

    (The answer to the last question is: We didn't. But we haven't found any good answer yet, unless we believe in Plato et al. But science is, metaphorically speaking, a house of cards built in the air. And I'm saying that with no disrespect to science. (And yes, I'm a bit drunk, but I'm still serious.))
    • This is why I am skeptical of AI.

      In order to develop software, you either need an fairly exact idea as to what you are engineering or you need to engineer something that can find the solution for itself.

      In the latter case, you need to engineer something that can *recognise* the solution when it has found it.

      When it comes to consciousness or even *knowledge*, good luck on either one of those!

      Those are philosophy questions, not science questions. You have to start with, "We are conscious. Animals are not. What's the difference?"

      Last I checked, not having a good definition of what "life" is didn't keep up from discovering the biochemical basis of it (DNA). 50-some years after DNA's discovery, we still aren't sure what life is.

    They haven't even scratched the surface. How about:

  • We all know that particles (i.e. electrons, protons) with opposite charges get attracted to each other.

    My question is...

    WHY? Yes, I know they're opposite charges, and the Coulomb's law and everything... but why? Any quantum physicist to enlighten me?
    • Science never answers to the question "why". Science proposes models (theories) that allow scientists to make predictions accurate to some degree, that is all.

      The Coulomb law is such a model, but it is as similar in accuracy with respect to the way electrons really behave as Newtonian mechanics is to the way gravity really works -- i.e. you can make very good predictions from the Coulomb law (Ohm's law, macroscopic electric fields, etc), but you can't predict lighwaves. The next level up would be the Maxwe
