Radioisotope dating

Its crust is continually being created, modified, and destroyed.As a result, rocks that record its earliest history have not been found and probably no longer exist.

After all, the ever-changing Earth rarely left a complete geological record.Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms." When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.Fossils are generally found in sedimentary rock — not igneous rock.Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!

Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.That means that in 704 million years, one gram of uranium will be reduced to ½ gram of uranium.



(On a planet like Venus, with no water, the depressions appear to form a vast plain above which rise plateaux).… continue reading »
