" Answer: Radiometric dating does not fit with the “young earth” view.
The moist-heat cooking method involves cooking with water or stock, like poaching fish and steaming broccoli.) in the history of mathematics reached an accuracy within 0.04% of the true value before the beginning of the Common Era (Archimedes).In Chinese mathematics, this was improved to approximations correct to what corresponds to about seven decimal digits by the 5th century.In this particular case, it takes 4,460,000,000 years for half of a sample of U238 to decay into Pb206.It takes another 4,460,000,000 years for half of the remaining sample to decay into Pb206 and then another 4,460,000,000 years for half of what’s then left to decay, and so on.If any of these assumptions are wrong, the method cannot accurately determine the age of a specimen.
While the second and third assumptions have always been a bit troublesome, especially the third assumption, which considers the original constitution of a particular specimen, the first assumption was thought to be a pretty safe bet since scientists were not able to vary the decay rates much in a lab. Carl Wieland explains, “When uranium decays to lead, a by-product of this process is the formation of helium, a very light, inert gas which readily escapes from rock.
Cooking methods can be broken down into three sub-categories: dry heat, moist heat, and a combination of the two.
The dry-heat method, which is a relatively quick process, adds crispness and flavor, but doesn’t tenderize.
It’s the slow-cooking of ribs that makes them fall-off-the-bone tender, and the hot deep-frying oil that gives donuts a crispy, golden brown exterior and soft, doughy middle.

The time it takes for half of a sample to decay is called a “half-life.” By measuring radioactive half-lives, by measuring how much parent and daughter are present in any given specimen, and by making certain key assumptions, scientists believe they are able to accurately determine the age of a specimen. The question is what are the underlying key assumptions and how reliable are they?
