Just a few general questions for TB or TC...
You've claimed that the Flood waters rose and fell hundreds or thousands of times to account for the cyclothems and all the other marine transgressions in the gelogic record.
You've also claimed that the mechanisms for this is the same as in conventional science - just accelerated by half a billion times.
Well then, let's list those mechanisms, and invite TB or TC to explain exactly how this all works.
Pennsylvanian cyclothems:
Midwestern North American cyclothems are thought to be controlled dominantly by eustatic sea-level changes caused by variations in ice volumes at the South pole. Evidence for this glaciation is abundant and well correlated with the cyclothems.
How do glaciations exist in a Flood? And how do they change in volume by the required amounts in a matter of hours or days? The thickness of the ice cover needs to change by a LOT - very quickly.
Eastern U.S. cyclothems are more tectonically controlled - subsidence, delta-switching, etc. In the normal scientific paradigm, the weight of the sediment accumulating isostaticlly depresses the crust. Mountain building buckles the crust into basins and uplands, which erode into the basins. Rivers change course.
If we speed things up by half a billion times, how can these sedimentary basins move up and down so quickly? Do we need rainfall to increase by half a billion times to allow rivers to do their thing so quickly? How can erosion reduce granites and other highly resistant rocks into clay, sand, and silt in a matter of days? Anyone who studies erosion soon learns that water alone does almost nothing to break down rocks into clays. It's a chemical reaction driven by soil acids. Can we calculate the required acidity of the soil and/or rainwater to accomplish the required erosion in only a few days?
The larger trends in eustatic sea-level change are thought to be caused by changes in sea-floor spreading rates, which lead to changes in average oceanic crustal temperatures -> crustal bouyancy -> ocean basin depth.
How can oceanic crust temperatures change significantly in a matter of weeks? Do we need to postulate thermal conductivity rates that are higher by half a billion times?
