(continued from Part 1)I have already concluded that attempts by Snelling, Austin, and Humphreys to estimate a maximum age of Earth’s oceans are both unscientific and inaccurate. More recent work […]
I suppose every good science story deserves a creative headline. Reporting the latest research on the boundary between the upper and lower mantle, however, were catchy titles like this:• New evidence […]
Is our universe is full of clues that it cannot be millions—let alone billions—of years old?Many young-Earth creationists are convinced this is the case, despite that no scientists are scrambling […]
