6-3-'24, WBR Live, “Daily Constitution”, “Weekend Spam”, (pics on wimkin) I'd like to start this week off with a couple of pics that keep reappearing on the 'net'. Sometime, in the Earth's distant past, this solar system was playing pool with the planets and material then available. It is unlikely that all the following happened all at once, but that too is possible. We can reasonably assume, now, that the moon was formed by the impact of a small planet/very large rock, very early in development. These kind of collisions appear to have been 'common' at that time, with reduced impacts as the system developed and stabilized. That may have been what happened to the mass between Mars and Jupiter as well, as well as -maybe- where (at least some) of the rocks causing collisions to the rest of the planets here as well. We usually don't see the amount of planetary collisions because of time and most planets are 'air/water/mud' conditions and 'heal' quickly. My question is: has / do the time and orbital mechanics reduce the amount and intensity of these collisions and near miss fly bys as all the mass somehow, eventually, 'finds a home'? Mars has the big azz scar across the surface, with indications of planetary disruption, long ago. The Earth has this big azz gap in Arizona called the Grand Canyon. How do we know that the canyon was formed by erosion? Were -both- these scars formed by some energy activity reaction from a close “Fly By” (different in distance and velocity) in the distant past (possibly by the same 'rock' at the same time even?). Do 'erosion' and vaporization of a specific surface interaction leave separate, provable residue? IF so, and IF we can find a time of the event, -geologic-, we may have one step more of evidence that “Mu” was moved from the Indian ocean depth area to the south pole at the same time 100,000 years ago (+,-)?
