    Google Ciclids in Lake Victoria or Ring Species.

    We have directly observed the generation of new species of fish, specifically ciclids.

    Ring Species are rare but can be found several places. They are characterized by a genus of animal that surronds an impassible obsticale (Mountain range or huge lake etc). The original species expanded into the area and was split as it progressed down each side. By the time both sides met up on the far side of the obsticle they have all the appearances of two distinct species. However all the evolutionary changes are maintained along both paths. So while they can't directly breed with each other, they are still connected through a common ancestor which they CAN both breed with and still exists.

    Personally I have absolutly no problem with teaching creationism. However it should not come under "Science" class. It belongs in a moral/philosophy class that teaches the wide range of beleifs our society is based on and just like basic science should be mandatory...

    Absolutly...sadly skeptics are right more often then they are wrong.

    But I bet if a single atom was used even a few times it would be a net gain. The reason is simple. To electrolyze water you have to provide enough energy to ionize the hydrogen and thereby seperate it from the oxygen. The energy to ionize out of water is roughly the amount of enery created as the electron gets stripped off as it passes through the membrane which isextracted from the heat energy. So assuming he is even close to accurate and he gets a 50% efficiency then you would need to cycle the hydrogen twice to recoup the energy used to generate the hydrogen. From that point on, you have a net energy gain from that one hydrogen atom.

    While the principles seem to be sound the only question seems to be if it is "economical" which of course has it's own laws.

    For instance so long as the system creates any extra power, it still could be economical even if 90% of the energy is wasted regenerating hydrogen. If it costs $5 to extract extra power from your trash, I could see a huge market.

    As far as being skeptical, absolutly. But being skeptical means I am not going to buy it now or even invest more than token time researching it. But I am still going to remember it if it comes up again.

    Being skeptical doesn't mean ignore everything, it just means to keep everything in perspective.

    But the grandparents point about cycling the hydrogen 100's of times is still valid.

    We are assuming we have a heat source for this since that is what is used to generate the electricity. Why not have a resevoir of say a cup or two of water. As needed, the device can divert a little power to pull out the hydrogen and inject it into the system while releasing the oxygen. Water is very easy is contain and provides gobs of hydrogen gas per unit of liquid water.

    So long as each atom of hydrogen is used many times before it is lost (very likley especially if he can get to the 600 degree mark) than the minor energy cost to maintain it is worth while. All you have to do is dump a few cups of water into the resevoir every few weeks/months/years.

    Remeber, there is an equal number of positive and negative charges in the universe therefore over any great distance they tend to zero out to nothing. Also, the sun is still "local." When I was speaking of non-local influences, I was refereing to the distances discussed in the article, hundreds to millions of light-years. Over thoes distances, there is no measurable impact of electric charge. I would like to point out that even over a few miles it is extremly difficult to distinguish two oposite electrical charges as anything but a neutral point.

    Also, there is a difference between electric charge and electro-magnetic radiation. Electric charge has the same drop-off rate as gravity. Since gravity is only cumulative, the effect can add-up over distance whereas electrical tends to zero out. All other forces operate inside atomic radii and have no real effect outside that. Electro-magnetic radiation is an electric charge with a mutual supporting magnetic wave and does have a linear dropoff. However this combination has a net zero electrical charge and has no electrical effect execpt in rare conditions and therefore can be safetly ignored.

    We can directly detect gravity at interstellar distances. Even with the strength difference, we have yet to detect electrical charge at that distance.

    Hawkins radiation has been proven. Please look up "Zero-Point Energy." The Casimir effect is directly obsereved experimental proff of the QM effect I mentioned. This observation around a black hole would cause it to lose mass without directly releasing particles or radiation.

    The major problem with the voyager spacecraft is that their instruments are effectivly dead. We don't know what sort of local environment they passed through. There are a wide range of very reasonable explinations for the disparity. We just don't have the information to eliminate any of them and honestly we probably never will.

    The new energy levels we are about to reach are exciting but it is VERY unlikley that we will find anything that really disturbs the current theory. We are likley to find that is supports and extends our understanding rather than destroy what we have already seen.

  8. Re:UFO's like Dark matter DO exist on Necessity of Dark Energy Questioned · · Score: 1

    Actualy, the Hawkins radiation is a result of quantum mechanics (QM) and results BECAUSE nothing can escape a black hole.

    QM predicts that the baseline energy of empty space will spontaneously generate particle pairs (Electron/positron, proton/anti-proton). These will almost immediatly annialate each other leaving a net energy change of Zero. However if this happens onthe edge of a black hole, there is a possibility that one particle in the pair will escape while the other is eaten. Since energy can neither be created nor destroyed, the positive energy creted in the particle that escapes must be balanced by a net energy loss in the black hole. Therefore baring any additional mass falling into the black hole, it will eventually evaporate without anything escaping.

    The extra mass is "observed" through the motion of the galaxies. The outer portions move faster than they should. The theorized reason is that there is "Dark" matter outside the observable galaxy which compensates for this higher speed. I was wondering if the same theory could explain this discrepancy.

    While the orther forces ARE many orders of magnitude greater, it is important to realize that they do not have the range and do no sum up like gravity. Therefore on a local scale gravity can all but be ignored but on much larger scales, gravity surpasses all other forces easily and the effects of the other forces can safetly be ignored. The issue is when you attempt to NOT ignore the effects of all forces regardless of scale. This is the goal of the Grand Unified Theory.

    I do agree that the new energy levels created in the next few years will be exciting to watch.

    Just a small point...

    Dark matter JUST means unobserved matter.

    There are a LOT of theories about it from the mundane to the esoteric. I have heard dark matter theories suggesting that it is the influence of alternate universes and I have also hear that it is just a lot of very dim brown dwarf stars along with many others possible theories. Both theories explain why there appears to be extra mass around even though we can't see it. Both describe "dark matter" but one needs a huge leap and the other doesn't. The multitude of theories does not destroy the apparent necessity of dark matter.

    Also, we CAN directly observe black holes through the Hawkins radition they emmit. Plus their observable interaction on the rest of the universe also proves their existance. The observed gravities indicates that there is an apparent hole in space that is essentially black (a black hole). Therefor black holes exist...this doesn't say anything about the structure. Up until recently it was possible that a cluster of dark neutron stars were causing the gravity effects. About 10 years ago that theory was disproven and now a singularity is the most probably cause to explain the observation of "Black Holes."

    Remember, UFO's exist! Unidentified Flying Objects appear all the time. Are they spacecraft flown by martians? I doubt that theory is correct but that doesn't mean that the UFO has suddenly been identified just because you eliminate one theory...

    I have some concern about your statment.

    It is true that in all likelyhood mice brains function on the low level almost exactly like ours and I am willing to bet that reptile brains also exhibit this behavior. While I haven't examined their research yet I am confident in making the statment.

    The reason is simple...brains are built upon the prior layer. The cerebrum is layed on top of what is known as the "mamalian brain" which is on top of the "reptilian brain" which is on top of the "hind brain." Each "brain" from hind to cerebrum is increasingly complex but essentially takes the onput of the lower brain as it's input.

    For example, vision. Vision is first processed by the retinas (hind brain) which is then passed onto the reptilian brain where motion, light, dark and straigth lines are decoded. This is then passed onto the visual cortex (mamalian brain) whcih inerprets colors and complex shapes. Finally this information is passed onto the cerebrum where it is integrated into our personal experiences. If you damage and part of this chain then vision is dramatically effected.

    Since the type of neural modification underlies all the more advanced structures of the brain it is almost certainly universal. If you were talking about a mouses problem solving skills (cerebrum) I would agree with you but as for your prior post I say "bullshit."
