Charles, if stars shrink to become planets/moons, and if stars' cores and inner layers have elements heavier than Manganese, shouldn't planets/moons have a larger percentage of such elements? After all, it seems that the outer layers of stars would have to be lost first. Wouldn't they? Or would the heavy elements in the cores and inner layers transmute somehow to lighter elements?
If a planetoid were on an elliptical orbit with a perihelion inside Jupiter's orbit and an aphelion outside, can you calculate whether close approaches between the planetoid and Jupiter would more likely result in the planetoid being repelled from Jupiter or being gravitationally pulled into Jupiter resulting in a crash? Do you think the SL9 comet fragments that crashed into Jupiter were at all electrically repelled from Jupiter, despite then crashing into it?
Did you mean radiometric dating was reset? Radiocarbon dating only dates to 50 thousand years or less, in general. What exactly was dated to 4 billion years? Uranium-Lead ratios in lunar samples? I heard of samples that dated to 20 billion years too. What dates to 4000 years ago is the giant mammal extinctions, which apparently was caused in part by rapid continental drift, which caused the northern continents to move near the Arctic Circle, which caused the sudden freezing to death of the mammoths and other mammals in what is now the Arctic. Some of them were hit by micrometeorites from an impact, at least in eastern Siberia. The Younger Dryas impact layer extends at least over North America and Europe, apparently from before the supercontinent broke up, as would be shown by whether any of the YD markers, like nanodiamonds, are found anywhere on the Atlantic seafloor.Charles said: The planets "probably" formed at the same time, but the Earth seems to have been remelted during the Late Heavy Bombardment, and the radiocarbon dating was reset. That "seems" to be around 4 billion years ago, which matches the date of the mares on the Moon and on Mars. But is that number actually 4 billion years, or 4 million, or what? I don't think that it's 4 thousand, but I'm not familiar enough with the other dating methods to have my own opinion on the actual ranges.
Speaking of the Avalon forum, I change my mind about it, because they banned me after I tried to contact their members about trying to start a work group.
