But the salt crystal is spinning, at least once a day. Shrink it down to a really, really tiny fraction of its current size--which is exactly what happens to a molecular cloud--and you will see it achieve a surprisingly large angular velocity.
The only way to have a molecular cloud with a zero net angular momentum is to arrange it that way ahead of time (i.e. fine tuning).
Sauce for the goose.
More computer power will help, but the problem will remain that giant impacts are inherently improbable, and the Solar System's chaotic nature makes it impossible to re-run history and get the same outcome. "None of the scenarios for the Moon's formation is highly likely," Stevenson says.
That does not indicate what I believe about either scenario, it just means I don't think ludicrous applies.
That is due to external causes, which I have explicitly left out. The crystal also spins once a year and once every ~220 million years among likely other centers.
Yeah, no kidding. I read that as a lark a few months ago. When I finished, I started over from the beginning, trying to poke holes in it somewhere. I remember being surprised as how well-constructed the paper turned out to be.
Nerds-R-Us :^D
All I will tell you is that RA is in no danger of losing his eyesight.
Not at all. I told you I don't buy the "Mars-sized body" idea, either. I also have an impact-parameter fine-tuning argument against the notion, which I won't bother to write up here.
Still, the Venus idea is ludicrous for many more reasons than the MSB idea. First, the MSB would either be an interloper or dislodged by an interloper, so the formation arguments wouldn't apply. In Velikovsky's (medved's) model, Venus is excreted spontaneously by Jupiter, which is ludicrous in and of itself. Furthermore, the MSB would only have to interact once, whereas Velikovsky's Venus is asked to perform tasks all around the solar system. Finally, the MSB would have done its dirty work over four billion years ago, not recently as Velikovsky would have it.
One little spelling error and it's reproduced ad infinitum. It should be spelled, perturbations. Ok fellas, now have fun with that...
Well, there you go. But assume the salt crystal isn't on the Earth, but that you place it in space somewhere. I don't care where you put it or how, but I can tell you that it is not going to have zero angular momentum unless you work very hard at cancelling it out. The placement process, whatever it may be, will undoubtedly impart a nonzero angular momentum to it.
Molecular clouds are the same way, except that there is nobody meddling with it to make sure it doesn't spin. And if it does spin, however slowly, that angular velocity will be amplified by the collapse process. You see?
That's right and the name of our private home school is the same as your screen name. We're raising our kids to be critical thinkers so they can recognize the bad science behind the theory of evolution. Sorry evos, had to get that in there.
Thanks for the Feng story. It's a great reminder of the freedoms we have here that I will fight to the death to keep.
The sauce comment was not meant for you but for those that believe the moon hypothesis and so contemptuously dismiss the other.
But you are talking about the whole enchilada when you place it. That is external reference. I know that something spinning, spins. And as I pointed out to you long ago, which you did not understand, when something moves, everything moves.
But the question is, is that same "critical eye" universally applied?
As I've long suspected, that "control room" of his is just a cover for some really kinky activities. His guise as a SETI researcher is crumbling. But I'm glad you're taking care of his eyesight.
Actually, I've always liked the idea that the Moon orbited the mysterious fifth planet, and when those folks blew themselves up fighting off giant bugs 300 million years ago, the Moon was cast free and eventually ended up orbiting our world.
Yeah, he's one of those people that if he says something that is contrary to my judgment, I immediately start cross-examining myself because it is probably me that is wrong. I remember discussing this very concept with him when he was working on the paper and looking for some conceptual feedback to flesh it out, and he fielded my objections and questions with ease.
