If I were to try and revolutionize science, I wouldn't bother with the higher order observations such as stratigraphy, landscape evolution, or even biological evolution. Because these are all tightly-bound, and widely agreeing observations. They all point to an old earth, and changes in organisms over long spans of time. Nor would I try and sow doubt by pointing out minor and insignificant anomalies. By pecking at the surface of science, YECP's are doing little more than rearranging the deck chairs on the Titanic. Sure, it may look different, but the icebergs are still in the water, and the boat is still moving forward.
Instead, if I were to try and disprove all of these observations, I would attack the physical constants. If I could demonstrate that universal "constants" such as gravitation, nuclear strong and weak, even electrostatic forces varied over time, only then would it be possible to cast sufficient doubt over the concept of Unformity, providing an empirical and non-religious basis to support a young-Earth flood model.
If nuclear decay was faster, that means more heat - if we could show heat-flow through rock was reduced, then perhaps all this radioactive decay wouldn't have cooked all of Noah's family and the animals headed to the Ark. Unfortunately, we are faced with the problem of large bodies of intrusive, igneous rocks. To quickly cool (within a thousand years or less), heat dissipation would have had to be higher. Thus not only would we have to demonstrate heat flow was less, we then have to demonstrate how it also (either concurrently, or immediately following this flood) sped up. We could, perhaps, avoid some problems by focusing on the elements in rock forming minerals, such as silicon, iron, and magnesium - this way we can concentrate these variations within the crust. Or, perhaps there is some multiplier attached to these constants that can change - thereby altering the magnitude and direction of these constants.
So what is the value of this "constant" modifier? Well, the only source of information that suggests this is possible comes from some interpretations of biblical Genesis. We don't see consistent (let alone any) and, importantly, independent evidence of this modifier in action. The only record is a religious text (and, depending on which chapter you read, a widely varying one). Thus, it fails the basic requirement of science.
But, if YECP's could effectively demonstrate that physical constants could change - then things would at least become more interesting. Instead, nearly 60 years after Morris' "Flood Geology" book, we are still faced with the same inane arguments about the same rocks, the same claims, and the same lack of basic science (albeit dressed up with fancy new words and some vaguely scientific techniques).
