aharvey said:Okay, I've found where Brown does indeed say the top layer is granite and the bottom layer is basalt. I tell you, he doesn't make it easy!
For example, here's an odd tidbit. Here he writes that during the flood phase the water jetting upwards at supersonic speeds scraped off massive amounts of the cliffs, which seems a reasonable expectation. However, he then says that about 35% of the sediments so eroded in fact came from the basalt of the chamber floor.
This seemed odd to me for any number of reasons (basalt seeming less prone to erosion than granite, water would not be moving at supersonic speeds until it left the basalt floor, and would take potentially eroding sediments away from the basalt, etc.). So I checked out his footnote 38, which mostly documents why the water would move at subsonic speeds under the plate and discusses the implications for continental slopes and shelves, none of which seem to have anything to do with why the model predicts a 65/35 granite/basalt sediment composition.
If you read the last paragraph in this footnote, however, you will discover that this ratio is an empirical result of previous research, and neither an assumption, a premise, nor a prediction of his model at all!
bob, the post of mine that you quote here already told you what he said, gave you the link to the place where he said it, and provided the number of the footnote that supposedly explains it. What more could you possibly need? At this point I'm trying simply to understand exactly what the hydroplate theory is, which is enough of a struggle given the baffling way in which his ideas are "organized" in his book (at least the online version; is the printed version laid out differently perhaps?). If you are familiar with the theory and are willing to help, I appreciate it. Asking me to show you where Brown says a distorted version of what I said he said (complete with links to where and why) is not helpful.bob b said:I wonder if you could point out the place in his book where Dr. Brown claims that his model predicts a 65/35 granite/basalt sediment composition.
I was under the impression that this part was explained by the forces acting on a rotating object. Those forces make a rotating object's preferred shape a sphere and the molten inner Earth would respond to changes in its balance by moving mantle around to compensate. Of course this is dependent on a molten core which would need to be a result of creation, not of the flood.aharvey said:This ties in with a related issue I've been trying to understand. Brown repeatedly alludes (including in the link above) to the pre-Flood situation in which the weight of the hydroplate and hydroshell exactly balances the upward pressure of the mantle; when this balance is disrupted thanks to that fateful microscopic crack blasting water and hydroplate from along its seam into space, the mantle pushes up and buckles through, forming the worldwide Mid-Oceanic ridge. But why is the mantle exerting such a tremendous outward pressure over the entire planet? Again, given the relative mass of the Earth above and below the subterranean crust surface, logic would seem to suggest that changes in the hydroplate+hydroshell would barely be registered by the Earth's interior. It would rather be like breaking the skin of an apple causing its flesh to immediately push up through the cut. Does Brown explain this?
If I'm not mistaken, the spherical shape of a planet is largely a result of gravity pulling all particles as close to the center as possible. That's part of my puzzlement about why the surface under the hydroshell would be pushing out away from the center.stipe said:I was under the impression that this part was explained by the forces acting on a rotating object.

What goes up??stipe said:That would be because the crust was originally squashing it down. Remove the crust and, with nothing to push it down, it goes up.
But I thought it was crust, then water, then the mantle (also know as "The Mick"?--although since you are not from NY you are not likely to get that reference--but I will be mucho impressed if you do).stipe said:th' mantle.
Assuming it's molten.
Good work. The Mick is (was) Mickey Mantle--famous NY Yankee baseball player.stipe said:I don't know what you're saing Jukia. Yes it is crust-water-mantle, with the chamber basement in between the mantle and the water, but isn't the mantle molten today? I'm certain it is though I did leave university over 10 years ago. Things might have changed in that time...
Is 'The Mick' a baseball player?
mantle molten mantle molten...
Mantle was the best for a while, although he wasted a great portion of his talent on booze and women. When a kid I once ran into Mantle, Whitey Ford and Billy Martin in a hotel coffee shop in DC, they were having breakfast. When I asked for an autograph they said "Not right now, kid". If it happened today I would have realized that those 3 had probably not been to bed yet!stipe said:The current seafloor is supposed to be the remains of the original chamber floor. It has to underlay all the sediment deposited by the flood.
Mickey Mantle does ring a bell, though I guessed baseball on the strength of the Taiwanese pitcher over there at the moment. Wang Chien-Ming (王建民 ).
That sounds right.Jukia said:But to Dr. Brown. His theory states that the sea floor should be sediement and then the bottom of the original chamber floor? Do I have that right?
