Radioactivity and Earth´s Age

JOYLE_1909_Radioactivity_Geology

For a long time the apparent discrepancy between the age of earth and the age of the cosmos posed a great problem to geologists and astronomers alike.

Earth’s Age and the Cosmic Calendar

BRESSAN_Capo_Spartivento

During  the 19th century geologists realized that earth was quite older than previously believed, however this discovery posed an even greater question: what about the universe?  Did earth (like some fundamental creationists believed and still believe) predate the cosmos, were  earth and the cosmos created at the same time or came earth later?

On earth these minerals are mostly gypsum and halite, associated  with borates, potassium and magnesium salts. These minerals (not surprisingly) if found in [...]
