It is doubtful it was captured at all. Are you saying the moon doesn't have any carbonado (aka black diamond)? Who knows? It can probably be produced by shock, so on a cratered body like the Moon, you'd likely find some. I'm sure it's pretty rare, though. Just another trace mineral. From that absolutely terrific 2500 km crater, where the hell did the bulk of that lunar basalt and shards from the impactor go? Which crater is that? In any case, you'd expect the bulk of the material to come back down onto the surface. Very little is likely to achieve escape velocity. |

That is hardly surprising, given the broad definition of basalt, and the wide range of materials it can incorporate. Perhaps less than 1% of accessible basalt that's purely terrestrial is near 3.5 g/cm3. Are you talking about 10+ km deep TBM excavated basalt? (because that could fit) Are you suggesting that our moon was only recently captured? It is doubtful it was captured at all. Your purely subjective doubt is noted. Here’s an extremely simplistic simulator package that has a little something for everyone. Obviously aerodynamic drag that should have been much greater before we had that moon, as well as lacking important other factors of the lithobraking impact(s), loss/transfer of whatever ice and rock mass plus other tidal forces of the sun and possibly Venus are not involved within this simulation, but none the less it’s a good enough example of how a capture might actually be easily accomplished when the approach angle and velocity are just right. http://isthis4real.com/orbit.xml Launch angle / Launch force *** -128 6.2~6.15 *** -129 6.0 *** -142 4.8 *** -126.35 6.7 *** -126.34 6.71 *** -126.335 6.71 Just for fun, go with whatever launch angle and initial force. How about the complex tidal capture of Cruithne? Of course retro moons are still considered as most likely captured, and items like Sedna seem unlikely as original equipment. Only thus far have 540,000 some odd asteroids and small planetoids been identified, and those could represent 10% of what's out there, not to mention the Kuiper belt and Oort cloud of whatever Sirius should have to offer. Are you saying the moon doesn't have any carbonado (aka black diamond)? Who knows? It can probably be produced by shock, so on a cratered body like the Moon, you'd likely find some. I'm sure it's pretty rare, though. Just another trace mineral. Carbon isn't very rare, nor are those heavy metallicity elements. Are you suggesting that the vast majority of asteroids are made of wussy density and of only poor metallicity, and thereby of practically no value? From that absolutely terrific 2500 km crater, where the hell did the bulk of that lunar basalt and shards from the impactor go? Which crater is that? South pole crater, as mostly filled back in but having hundreds of other big, medium and small craters within. "The Aitken Basin is 2500 kilometers across" http://en.wikipedia.org/wiki/South_P...3_Aitken_basin In any case, you'd expect the bulk of the material to come back down onto the surface. Very little is likely to achieve escape velocity. I believe it kind of depends on the impact velocity and its angle of contact. Glancing blows would certainly allow greater amounts of impactor shards and crater mass ejection to exceed 2.4 km/sec. Then where did all of that crater displaced and/or ejected material go? (because our NASA/Apollo missions found hardly any, and most of it was a pastel gray or kind of guano off-white monochromatic material that wasn't even the least bit UV reactive, as well as they never even brought back any sodium or hardly a speck of any heavy elements, as though our moon that's supposedly made from Earth is inert) http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” |

Adult lion on adult lion they do not normally fight to the death. Adult humans do not normally kill other humans of any age...were you trying to make some sort of point? Lion on other preditor species like tiger they will. And you cannot blame an obligate carnivore for killing other animals or eating fresh meat. No one blames them, but because they respect no rights, and have no concept of rights, they have no rights. They do follow the "Might is right" philosophy - a trait they share in common with most dictators and power hungry politicians. Who, having violated the natural rights of so many others, eventually find out that they have lost claim to most if not all natural rights. Think Gaddafi. How is that different from human behavior? Throughout most of history, and in some societies today, it is considered the right of the father, and sometimes mother, to kill their offspring. It has been considered the right of the strong to take from the weak. "Might is right" has been (and in truth, still is) considered the natural order of things, and not connected to fairness. Indeed. You only have to look at all the stories involving wicked step-mothers in fairy tales and pantomimes to see that human society has historically rather similar behaviour. Most of these narrative tales have a certain amount of truth in them. Those sorts of tales portray the acts of a small minority of "wicked" characters. The real, normal, peaceful people who recognize right from wrong, and respect natural rights, do not generally inspire any stories. Infanticide is still practiced and *skews the sex ratio in certain countries even today. In the past female life expectancy was lower because of childbirth and fathers remarried more often - modern medicine has reversed that. What you and Peterson seem to be utterly unable to grasp is that just because natural rights are sometimes violated, that does NOT mean that natural rights do not exist. You're viewing the world through rose colored glasses if you think otherwise! Nature is red in tooth and claw. Humans are unusual in that we have codified rules of good behaviour and developed written culture. No other animal has made that leap. We wrote down the natural rights, but they existed anyway. Though plenty of species have developed societal learned behaviour passed down generations like songs, or particular ways of exploiting resources. Corvids now appear to be a lot smarter than people thought and are quite clever at learning to use tools. Learned calls and tool use by animals don't have anything to do with the natural rights possessed by humans. |

It can be. And if you'd read any of the research, A whole lot of soft science, open to interpretation. you'd know that these matters are discussed. And controlled. Hand waving. Which means that there is good reason to think that the researchers are actually seeing what they appear to be seeing. Wishful thinking, which has no bearing on the fact that humans have natural rights and animals do not. For example, monkeys might share food, but that is due to some survival value for the species than to any concept of fairness or justice. *Certainly lions, which kill cubs of other lions and which have been seen eating prey that is still alive, have no concept of "rights." That is not certain at all. It is possible. But it is certain that animals other than humans have culture, and it is virtually certain that animals other than humans have consciousness and self-awareness. It is also certain that human behavior stems from issues of survival value, just like all other animals. So logically, it would be extraordinary if we DIDN'T see parallels to complex human behavior in other animals. And it strongly appears that we do. None of that, even if it were true, has any bearing on a human being's natural rights. You use the word "logically" but your statements have no logic. It increasingly appears that the differences between humans and other animals is a matter of degree, not fundamental quality. What a meaningless statement, bordering on tautology. Hardly. It is an increasingly mainstream viewpoint of both anthropologists and animal behaviorists. Soft science. You are guilty of allowing your PHILOSOPHY to alter your interpretation of SCIENCE. So far you have offered absolutely no evidence at all that animals have a concept of rights. |

So if your neighbors come over and steal your horses, that would be OK, then? You're viewing the world through rose colored glasses if you think otherwise! Might is not right, and never has been. |

A child will (as we would normally expect) mature and recognize right from wrong, but a lion will never do so. One doesn't usually see a lion cub committing "murder". So what is your point? Murder is the unlawful killing of one human by another, so the term doesn't apply here. Earlier it had been suggested that killing an animal might someday be considered akin to murder. So which is it? What you should be discussing is killing, and in most species, the killing of one member of a society by another member of that same society is fairly rare. It happens all the time among newly hatched birds. And that's not surprising, given that there are obvious evolutionary reasons that such behavior would be uncommon. You need to study some evolution. There are also many cases where killing does occur, both in human and animal societies. In neither case is much of this connected to any sort of concept of right or wrong. NO, we consider the killing of innocent humans to be wrong. Natural rights to which we are all entitled, even if some of us (you included) want to use some different system. Sorry, you have still failed to demonstrate in any way that this concept has any meaning. Again, you are allowing your PHILOSOPHY to blind you to actual evidence. Natural rights exist, even if your particular side branch of the human family tree hasn't evolved enough to understand them. It is possible that natural rights exist, just as it's possible that some natural rights giver exists. Now you are trying to tie the concept to religion. That is a very illogical and deceitful strategy on your part. But in the absence of evidence for either, I prefer the intellectually honest route of not believing in something for no reason other than the warm and fuzzy feeling it might produce. There is really nothing intellectually honest about you. The intelligence and insight required to be able to understand natural rights is not something you possess. Your natural rights remain, so long as you recognize that other humans have the same rights. *A stable and just government is not possible without the recognition of and respect for natural rights. Nonsense. Most stable governments have done just fine without any such recognition. And "just" means nothing more than what most people in that society choose to make it mean. Stable AND just government, not stable OR just government. Learn how to read. No. A relatively small percentage of people in most societies were actually slaves and an even smaller percentage were slave owners. Irrelevant. Most societies have considered slavery normal and right. The relative number of slaves to slave owners doesn't matter. Ok, let's see. Most people recognize the existence of natural rights and abide by them. A small number of people do not, thereby, in your small mind, negating the possibility of natural rights. It was hardly the norm in most societies. *And I doubt very many of the slaves were happy about it either. Not only was it the norm, but most historical evidence suggests that slaves considered their status normal. "Escape" wasn't normal, and slave societies often had their own hierarchies. So if slavery were legal, you would not have any problem with that? If someone decided tomorrow to seize your property and send you to a "work camp" you would have problem with it? I mean, after all, such things are the historical "norm" according to you. Haven't read much history, have you? I doubt you have read any at all. Even if you did, you sure didn't understand much of it. |

Or more relevant to this discussion, any evidence supporting the existence of natural rights for humans. Your position is philosophical, and not particularly rational. It is perfectly rational. YOU are irrational. In the absence of evidence for something, a rational person will take the simpler view that this "something" doesn't exist. A rational person understands that natural rights exist. You choose to believe in something that lacks support, I choose to treat it as not existing. If you choose to deny the existence of natural rights, then you would have to rely on a government or "society" to tell you not to kill or steal, and to keep others from killing you or stealing from you. There's a big difference, there. Perhaps you were raised to believe in religion as a child. You really should not have gone there, Peterson. If you think that right and wrong are determined by governments and society, you now need to explain away the fact that religions are often largely concerned with concepts of right and wrong. If you don't think that natural rights exist, and you deny the value of religion, then how do the concepts that lead to laws against murder, slavery and theft arise? Count yourself lucky that even though you have no belief in natural rights, most of those around you do. Your life would be much harder otherwise. That is usually enough to ruin a person's mind for the rest of their life. I would suggest that since you do not already understand the concept of natural rights among human beings, that perhaps you are not a human being. Or perhaps you are -almost- genetically human, but lack true humanity. Or perhaps you are a 'bot or maybe something even worse. |
