It appears to lie solely in the assumption that if there is no moon event the planet will be all ocean. That does not compute unless we can explain the disappearance of the moon of Venus. If Venus had had the same amount of water as earth, and there is little way to explain a significantly different amount, there should be enough water vapor in its atmosphere to 9000psi (600 At.) of pressure on the surface. But last I heard there is negligible water in the atmosphere and clearly no such pressure. We have no idea if there is a minimum amount of ocean needed to approximate an ecology like our own however it appears reasonable that all else being equal the amount of rainfall is proportional to the evaporative surface of the oceans. It also follows as a reasonable assumption (but which cannot be supported in the least, that the more life the faster evolution but we are not in a rush so a few extra billion years does not matter. However surface area only would be a factor in rainfall. Depth would not be. So without a moon and nothing lost there is nothing prohibiting large and shallow seas. The South China Sea with a depth averaging over a few hundred feet has all the characteristics of any other ocean save it is warming at all depths. This would speed evolution among the cold bloods. Tectonic forces would still raise mountains and and volcanoes broad expanses like the Deccan Plains. As long as the planet is large enough there is no reason to suggest plates would not form and move. The only different would be the longevity of the created land above the surface. Given Earth we find old and new mountains in proximity such as in the US so we can expect there would always be dry land. So maybe a world with shallow seas needs also have greater tectonic activity requiring a somewhat more massive planet and the world average being more like Japan. So maybe the funny thing about ET is if the ground shakes he curls into a ball.

However, it might if it had oceans. Maybe I missed that too but I thought plates moved because of convection current in the mantle. I think itīs believed Venus' oceans evaporated, once the Sun warmed up, and that the water left the planet altogether being blown away into space. What remains is possibly the most hostile to life plase in the solar system. I see no way for water to preferentially be removed as at that temperature was is a gas like any other. -- Itīs a mistery actually how plate tectonism began on Earth. What is the mystery? Radioactive decay heats the core. The core rises but cannot rise uniformly every place. The first instability creates a convection current. They continue until the core cools. As water is present in great amounts in the crust, it has been suggested that it sort of acts like a grease on the plater, lowering the threshold where bounds between rock brake apart. Sliding and breaking are different things. Itīs believed that water left Venus and was blown into space. Look it up.

It appears to lie solely in the assumption that if there is no moon event the planet will be all ocean. That does not compute unless we can explain the disappearance of the moon of Venus. We can; Venus is too hot to have liquid water. But the case for the Moon being responsible for continents is made pretty convincingly in the book Rare Earth. IIRC, it basically goes like this: without the impact event that blasted much of the Earth's crust into orbit (forming the Moon), our crust would be too thick to support plate tectonics (just like Venus, I think). So they would end up a very uniform thickness, and the only mountains that would form would be from volcanoes, and these would quickly be eroded back down, leaving a uniform planet-spanning ocean. It's only because our crust is so thin that we can have tectonics and enough variation to produce continents and oceans. Hm. I'm not explaining this very well, but check out the book, it spends a chapter or two on this topic. Best, - Joe -- "Polywell" fusion -- an approach to nuclear fusion that might actually work. Learn more and discuss via: http://www.strout.net/info/science/polywell/ Hmm, plate tectonics does perform a pretty effective recycling of materials. That means theyr availabilty is maintained for processes abow ground. I have also heard speculations about effects of water being present in the crust, about the precense of life and what effects it may have on the crust. It appears though certain that plate tectonics help the Earth staying livable. Our planet really looks like an extremelly far out outlyer variable. The more unique characteristics of a planet you consider the more of an outlier it appears to be. But none of those apply to life on land which we assume is a prerequisite to visiting us. Recycling sounds like something interesting but since the issue is life on land how much dry land has been recycled since then? And I know of no variation in land biomass based upon who long since the last "recycle." In other words, no connection. Think about it, carbon dioxide has a tendency to react with materials and form carbonated rock. Oxygen also forms great many combounds with materials. The resycling which occurs melts old rock and released its constituent parts back into athmophere, back into nature. This aspect may be really important. The gulf between 'may be' and 'is' is so wide we can't hang any knowledge of earth on it much less extrapolate. A full 1/3 of the earth's surface carbon cycle is completely unknown. The amount of human CO2 release is about 10% of the uncertainty in how much CO2 there is in the atmosphere. I see no way to for any suggestion as to the importance of subduction just on the earth to be more than speculation. -- In time of war both sides claim to be defending themselves to the public but in retrospect we know both governments wanted the war but the people did not. -- The Iron Webmaster, 4843 nizkor http://www.giwersworld.org/nizkook/nizkook.phtml environmentalism http://www.giwersworld.org/environment/aehb.phtml a9 |

That some of the dragonflies we say are in fact ET or more accurately a part of ET. Just possible - but I do not think so. You see ET would have come here for some sort of reason, and I think if ET had really been here we would know about it. Anyway Occam's razor explanation is simply no ET. With a sample size of one we can know nothing. With a sample size of one we have zero idea of probabilities or possibilities. As the vulgar say, we don't know jack. Every civilization is confronted with identical technological challenges. If we can build 0.15 micron chips they can be built on Alpha Centauri, If our technology is moving to molecular memories ET is sure to have them (bearing in mind existence at all!). Yes we can make reasonable deductions. What can be done and what is done are different things. To digress. There is a new and somewhat credible theory that nerves in fact transmit sound with the electricity as an artifact. (It has to do with no one knowing why any anesthetic works.) The earliest frog leg experiment can be explained with this alternative of the artifact being reciprocal. Most of the original reason for studying electricity was that experiment and the reason was it caused life. One expression of this was Frankenstein and animating a corpse with lightning. Without this kind of interest it is unlikely we would have electric lights today. So all it takes is life out there not to have nerves using electricity so this experiment never happens and you have something else coming first. Electricity may never come until there are better things. Depending on the order of things occurring the future is always different. Without WWII the atom bomb comes long after GE and Westinghouse have built hundreds of nuclear power plants because no one is afraid of them. In another post one answer to why no RF detection is they use cable. The US could have started switching to cable in the 1950s but there was a Supreme Court decision against it. No technology but a vagary of a court decision. A couple years ago there were reports that a chance discovery found a way to refine titanium as easily and cheaply as aluminum. That is discovered before the aluminum method and our world is much different. And if titanium had been around as long as aluminum would the next Boeing be made of titanium instead of carbon composite? Genetic engineering is just a faster was of doing what breeding and selection can do and does not result in anti-GM hysteria. Alcohol from weeds for fuel could have happened decades ago with minor changes. We do not have too many of these possible differences because many of them are just being discovered. Very few of them are linearly dependent on everything that came before. We cannot predict what we will be using a century from now as even the best thinkers such as Art Clarke have only gotten a couple things right and then only a few decades before. One despairs to predict what a totally and completely unrelated form of life with an unknown history might choose to do. Saying anything definitive is folly. It is clear to me that the Area 51 legends are 1950's SF. They cannot be anything else. Either ET is flying tiny robotic spacecraft or he is not flying at all. These are the only two possibilities that remotely pass logic. I did not mean to suggest Area 51 is SF per se. The problem with it is either it is hopeless or it does not exist because we have gotten nothing from it. Everything has to trickle out of the military in some form or other regardless of classification. While there is a lot to say for the tiny robots that also is an idea which had not be tested so we really do not know if it is a good idea or not. Even if it is we have no idea how long it will be the best until something better comes along. And one of the reasons we like the idea at the moment is the redundancy permit losing many units without loss of capability. If that is part of their reasoning then closely examine all small stones that appear out of place. Rand Simberg and Fred Mc Call simply refuse to think rationally. Intersellar travel can be effected using a Von Neumann probe. It cannot be done any other way. FTL is impossible. I do not speak for anyone else. As to FTL being impossible, who told you that and why did you believe them? Within special relativity there are several ideas on how to do it which are merely grossly impractical to test at the moment. And then who said SR is right? And as there is no general solution to the formulations of General Relativity it might be already discovered simply not solved as yet. If you travel FTL you must postulate a favored frame of reference. Who told you that and why did you believe them? In terms of General Relativilty solutions to the equations are possible which are not physical. Let us take a particle. Let it travel FTL, in onr FOR. In another FOR it is going backwards in time. We thus have a situation where we are sending a particle and it is arriving back before it was sent. We can always do this by adjusting FOR. This is independent of technology, warp drive (warped where?) or wormholes. We can postulate two wormholes each travelling at a different speed. In terms of GR we do not have a general solution for any of them not just for non-physical. The problem with time travel is the only thing we know about it is that it can be treated as it is in relativity. The problem with FTL travel is that if it were possible the place we stop would still function as though it were at the leading edge of forward time according to current understanding meaning we cannot have done what we did according to SR. However until we actually do it we won't know what it will look like. Once there the reason it was possible might be obvious. Contradictions like this are resolved in Elementary Particle Physics by the use of Feynmann diagrams. Elemetary Particle Physics is a very bootstrap like discipline. You have quarks, there are 3 quarks to a baryon. There are guage particles that quarks exchange. A quark is in fact more massive than a baryon, but 3 quarks weigh less than 1 because of E = Mc^2. When we construct a Feynmann diagram for an FTL transaction we find that the mass of a particle becomes infinite. And yet the nagging feeling we are barking up the wrong tree with these approaches because no matter how good the model fits the facts more different types of particles appear. When a predicted particle is found something new appears in the process. Sort of like early chemists trying to make sense of things before the idea of elements was found to work. Maybe e=mc^2+charm unattached to any particle. The characteristics conserve the particles rather than vice versa. Energy has more forms than particles but oddly no characteristics like strange and charmed. Why? I mean why not different types of velocity and photons instead of assigning the differences to the particles? I tend to believe this would be inflationary. Just as a free quark will give rise to one or more baryons so this particle would give rise to many other particles. To achieve warp/wormholes we need negative mass. Negative mass was thought (in inflationary theories) to have been present at the big bang where matter inflated. Either we can't get negative mass or if we do it would be incredibly unstable. It is after all the stuff of Inflation. If all you need is negative mass, that which pushes, just collect some dark matter ... or would that be dark force? It is hard to talk about the dark side of the force. But since dark matter hangs around light matter and Vger is accelerating perhaps it is just the speed of light that is changing as it gets further from the light/dark mass of the sun. If we have FTL particles "tachyons", they are possible, whether they exist is an open question, but if they do they are subject to Cosmic Censorship. They cannot be used for routine signalling. As with other particles, discover a tachyon and we will have an entire cascade of new particles that don't make a lick of sense in the same discovery. None of the above is to be taken seriously. Rather I only pose them against the certainty given to a century old idea that cannot be fit into any unified theory of everything. I don't just say things, I look at the way human technology is moving. ET technology will have traversed a similar route to the one we are traversing. This is my central assumption. To me it is the only assumption worth making. If technology on ET planet has moved any other way an explanation of why terrestrial technology has taken the route it has is clearly called for. Why would you require an explanation for a sample size of one? Because that sample tells us the technological possibilities. The point being it can only address the scientific not the engineering possibilities. And it says nothing about the human or inhuman paths to those choices nor the decisions that will be made among them. As to how human technology is moving, I can see one line of thought in that but without disease being the punishment of god the biological revolution could have easily preceded the industrial revolution and that would put us in a much different place than we are today. Interesting but wrong. Katrina (and 9/11 as well) was considered by the likes of Pat Robertson and Gerry Falwell to be the punishment of God. But today few take them seriously and almost no one does outside the sermon. The two ideas are compartmentalized today. It was not always so. Newton, being a minister in all but ordination, did not compartmentalize. And most of his life's work was on alchemy. Nothing like barking up the wrong particle tree. One interesting point I am reminded of here. One thing that has been discussed in this usergroup has been a sunshield to prevent global warming. If you put it at the Lagrange point it is not flexable. If hovever you are at MEO you could in fact think in terms of controlling hurricanes. After all hurricanes are chaos. What is chaos? It is to do with the eigenvalues of the system. Chaos happens when we have positive eigenvalues that can grow. Damp them down and there is no hurricane. Diffiicult, but not impossible. Which of course depends upon that description being correct and a very correct guess as to the right thing to control. One can hope but if math works it isn't chaos but the engineer running the satellite is Maxwell Smart. All civilizations, whatever their religious beliefs have given a high priority to the advance of medical science. In effect the medical profession have always told the religious leaders to "go to Hell" if that isn't too much of a pun. All OUR civilizations says nothing about anything else. The problem with advances is it takes some skill to measure an advance to see if you have one. If Pasteur had not had the drama of rabbis he might have been run out of the profession as was the man who discovered handwashing would prevent birth fever from killing 30+% of women. Pasteur had near 100% success whereas whathisname only reduced it to about 10% and statistical tools were not standard medical practice. But that was some 40-50 years before Pasteur. So have statistics adopted by doctors before his time and we have the germ theory earlier. Or, as I suggested in another forum, have him born two centuries earlier when he would have his washing solution blessed by a priest and we get the benefits if not the reason why centuries earlier. Rate these 3 things. Sanitation/sewerage, Anathesia or DNA. Which of those was more important. The general public says "sanitation", the medical profession says "anathesia" and scientists say DNA. To build a sewerage system you need industrialisation. Rome didn't. In fact all of our systems are still based upon observing water runs downhill. Anathesia requires a good knowlege of chenistry. But no one knows why they work. The funny thing is all the anesthetics, save for the "stupefying" ones like nitrous oxide, have the same solubility effect on the layer covering nerve cells and zero effect on electrical transmission. DNA promises not only a revolution in disease control, but also better mineral extraction, perhaps even a role in producing hydrogen from sunlight. So you would rate two in the bush over one in the hand. See my point on the power of decision in determining the path of progress? You are aware the promise of DNA has been around three years longer than the promise of fusion power? Could a civilization have developed genetic enginnering before it developed deep mining. Good SF, but I doubt it. Just an example of course. Forget the name at the moment but some monk was the first to develop the rules of breeding but was only discovered after someone else was given the credit. Have the monk get published and the original credit. Then scientific breeding begins a century earlier. GM is not much more than a fast track to breeding. If you want a crop that can grow with less water you find a strain that does and breed for it instead of finding a gene for it some place else and inserting it. If you want might have beens, assuming all else being equal a shift in gun technology by a mere twenty years faster or slower would change the entire character of the American Civil War as well as WWI and thus WWII. There is nothing inherently preventing such a minor shift. The wars might not have taken place at all. Precisely. A major difference in civilization which shifts something like the brass cartridge only a couple decades changes the development of the Bomb in 1945. And most of it was trial and error. One lucky working idea early on or it not coming until much later and a non-deterministic process is entirely changed. If ET has developed molecular memories. DNA (400 MB on a sperm or ova) this would give an initial weight of a gram of less for a VN probe. This is a matter of pure maths. I am not just saying it. It would seem inconceivable to me that an interstellar flight would begin without such technology. Which is the paradox of the paradox. If we assume that we cannot say there is a Fermi paradox. Why not? This rechnology is perfectly possible to develop. Because if you assume there is no way to tell if they are here or not then the question, Where are they?, is meaningless. Without the question there is no paradox. About Fred and Rand - I wonder one thing. Are they professional disinformers? Is there a reason why we should believe in UFOs in the 1950s sense. Are real UFOs black aircraft for which ET is a cover? It would all fit. I can't of course prove it. I can only prove that ET based UFOs cannot exist. I can't say what else does. I am not aware anyone who has seriously considered the possibility of ET visiting who is stuck in the 1950s which were little different from War of the Worlds. There are still kids around but we don't take them seriously. I have considered it from the mid-50s before I heard of puberty and I haven't thought so simply since then. Rand & fred. The Fermi paradox is far too serious a scirentific question for the likes of you to muddy the water. If by that you mean it do not leave it in the simplest and earliest form and likely not the way Fermi meant it in the first place, remember it is only someone saying what he remembers Fermi saying, then I admit to muddying the water. However there is no water to muddy as this is a discussion of the idea not of a particular formulation of the idea. If you want to discuss what someone remember Fermi saying that is worthy of a separate thread that everyone taking this seriously can ignore. What I am alluding to is this. ET spaceships of whatever vintage are a good cover for black flight. In fact when a stealth bomber was seen over Phoenix the Pentagon pulled out all the stops and produced an ET mannikin. This is what I am talking about. We need to discuss the Fermi Paradox without the Pentagon flying steath bombers and blaming ET. Similarly unless all observations are really alien visitors any visitor can expect natural phenomena to cover its visits and not need to take any precautions. It would not take the first scout too long to discover people in all history have been seeing things in the night sky even entire armies of men on horses. In fact all the christian talk of heavenly hosts meaning angels it properly translated as armies in the skies. In that time a flying saucer would be a disappointment to anyone expecting to see something interesting. -- In time of war both sides claim to be defending themselves to the public but in retrospect we know both governments wanted the war but the people did not. -- The Iron Webmaster, 4843 nizkor http://www.giwersworld.org/nizkook/nizkook.phtml commentary http://www.giwersworld.org/opinion/running.phtml a5 |
